d4417eb662 pullup:
Partial fix for RT #2053.  The potential for deadlock still exists,
but it is much less likely to occur because we now only take the ADB lock when
the
external reference count reaches zero, not every time it is decremented.
Althought this does not actually fix the bug, it at least lets us make
progress on testing fixes for other bugs affecting shutdown of multithreaded
servers.

When returning DNS_R_CNAME or DNS_R_DNAME as the result of an ANY or SIG

Frequently Asked Questions about BIND 9
Copyright © 2004-2010 Internet Systems Consortium, Inc. ("ISC")
Copyright © 2000-2003 Internet Software Consortium.
Q: Why doesn't -u work on Linux 2.2.x?
-----------------------------------------------------------------------
A: Linux threads do not fully implement the Posix threads (pthreads) standard.
In particular, setuid() operates only on the current thread, not the full
process. Because of this limitation, BIND 9 cannot use setuid() on Linux as it
can on all other supported platforms. setuid() cannot be called before
creating threads, since the server does not start listening on reserved ports
until after threads have started.
1. Compilation and Installation Questions
In the 2.3.99-pre3 and newer kernels, the ability to preserve capabilities
across a setuid() call is present. This allows BIND 9 to call setuid() early,
while retaining the ability to bind reserved ports. This is a Linux-specific
hack.
Q: I'm trying to compile BIND 9, and "make" is failing due to files not
being found. Why?
On a 2.2 kernel, BIND 9 does drop many root privileges, so it should be less
of a security risk than a root process that has not dropped privileges.
A: Using a parallel or distributed "make" to build BIND 9 is not
supported, and doesn't work. If you are using one of these, use normal
make or gmake instead.
If Linux threads ever work correctly, this restriction will go away.
Q: Isn't "make install" supposed to generate a default named.conf?
Configuring BIND9 with the --disable-threads option causes a non-threaded
version to be built, which will allow -u to be used.
A: Short Answer: No.
Long Answer: There really isn't a default configuration which fits any
site perfectly. There are lots of decisions that need to be made and
there is no consensus on what the defaults should be. For example
FreeBSD uses /etc/namedb as the location where the configuration files
for named are stored. Others use /var/named.
Q: Why does named log the error message "no TTL specified" and refuse
to load my zone file?
What addresses to listen on? For a laptop on the move a lot you may
only want to listen on the loop back interfaces.
Who do you offer recursive service to? Is there are firewall to
consider? If so is it stateless or stateful. Are you directly on the
Internet? Are you on a private network? Are you on a NAT'd network? The
answers to all these questions change how you configure even a caching
name server.
2. Configuration and Setup Questions
Q: Why does named log the warning message "no TTL specified - using SOA
MINTTL instead"?
A: Your zone file is illegal according to RFC1035. It must either have a
line like:
A: Your zone file must either have a line like
$TTL 86400
at the beginning, or the first record in it must have a TTL field, like
the "84600" in this example:
at the beginning, or the first record in it must have a TTL field,
like the "84600" in this example:
example.com. 86400 IN SOA ns hostmaster ( 1 3600 1800 1814400 3600 )
Q: Why do I get errors like "dns_zone_load: zone foo/IN: loading master
file bar: ran out of space"?
BIND 8 incorrectly accepted files that had neither.
A: This is often caused by TXT records with missing close quotes. Check
that all TXT records containing quoted strings have both open and close
quotes.
Q: How do I restrict people from looking up the server version?
A: Put a "version" option containing something other than the real version
in the "options" section of named.conf. Note doing this will not
prevent attacks and may impede people trying to diagnose problems with
your server. Also it is possible to "fingerprint" nameservers to
determine their version.
Q: How do I restrict only remote users from looking up the server version?
A: The following view statement will intercept lookups as the internal
view that holds the version information will be matched last. The
caveats of the previous answer still apply, of course.
view "chaos" chaos {
match-clients { <those to be refused>; };
allow-query { none; };
zone "." {
type hint;
file "/dev/null"; // or any empty file
};
};
Q: What do "no source of entropy found" or "could not open entropy source
foo" mean?
A: The server requires a source of entropy to perform certain operations,
mostly DNSSEC related. These messages indicate that you have no source
of entropy. On systems with /dev/random or an equivalent, it is used by
default. A source of entropy can also be defined using the
random-device option in named.conf.
Q: I'm trying to use TSIG to authenticate dynamic updates or zone
transfers. I'm sure I have the keys set up correctly, but the server is
rejecting the TSIG. Why?
A: This may be a clock skew problem. Check that the the clocks on the
client and server are properly synchronised (e.g., using ntp).
Q: I see a log message like the following. Why?
couldn't open pid file '/var/run/named.pid': Permission denied
A: You are most likely running named as a non-root user, and that user
does not have permission to write in /var/run. The common ways of
fixing this are to create a /var/run/named directory owned by the named
user and set pid-file to "/var/run/named/named.pid", or set pid-file to
"named.pid", which will put the file in the directory specified by the
directory option (which, in this case, must be writable by the named
user).
Q: I can query the nameserver from the nameserver but not from other
machines. Why?
A: This is usually the result of the firewall configuration stopping the
queries and / or the replies.
Q: How can I make a server a slave for both an internal and an external
view at the same time? When I tried, both views on the slave were
transferred from the same view on the master.
A: You will need to give the master and slave multiple IP addresses and
use those to make sure you reach the correct view on the other machine.
Master: 10.0.1.1 (internal), 10.0.1.2 (external, IP alias)
internal:
match-clients { !10.0.1.2; !10.0.1.4; 10.0.1/24; };
notify-source 10.0.1.1;
transfer-source 10.0.1.1;
query-source address 10.0.1.1;
external:
match-clients { any; };
recursion no; // don't offer recursion to the world
notify-source 10.0.1.2;
transfer-source 10.0.1.2;
query-source address 10.0.1.2;
Slave: 10.0.1.3 (internal), 10.0.1.4 (external, IP alias)
internal:
match-clients { !10.0.1.2; !10.0.1.4; 10.0.1/24; };
notify-source 10.0.1.3;
transfer-source 10.0.1.3;
query-source address 10.0.1.3;
external:
match-clients { any; };
recursion no; // don't offer recursion to the world
notify-source 10.0.1.4;
transfer-source 10.0.1.4;
query-source address 10.0.1.4;
You put the external address on the alias so that all the other dns
clients on these boxes see the internal view by default.
A: BIND 9.3 and later: Use TSIG to select the appropriate view.
Master 10.0.1.1:
key "external" {
algorithm hmac-sha256;
secret "xxxxxxxxxxxxxxxxxxxxxxxx";
};
view "internal" {
match-clients { !key external; // reject message ment for the
// external view.
10.0.1/24; }; // accept from these addresses.
...
};
view "external" {
match-clients { key external; any; };
server 10.0.1.2 { keys external; }; // tag messages from the
// external view to the
// other servers for the
// view.
recursion no;
...
};
Slave 10.0.1.2:
key "external" {
algorithm hmac-sha256;
secret "xxxxxxxxxxxxxxxxxxxxxxxx";
};
view "internal" {
match-clients { !key external; 10.0.1/24; };
...
};
view "external" {
match-clients { key external; any; };
server 10.0.1.1 { keys external; };
recursion no;
...
};
Q: I get error messages like "multiple RRs of singleton type" and "CNAME
and other data" when transferring a zone. What does this mean?
A: These indicate a malformed master zone. You can identify the exact
records involved by transferring the zone using dig then running
named-checkzone on it.
dig axfr example.com @master-server > tmp
named-checkzone example.com tmp
A CNAME record cannot exist with the same name as another record except
for the DNSSEC records which prove its existence (NSEC).
RFC 1034, Section 3.6.2: "If a CNAME RR is present at a node, no other
data should be present; this ensures that the data for a canonical name
and its aliases cannot be different. This rule also insures that a
cached CNAME can be used without checking with an authoritative server
for other RR types."
Q: I get error messages like "named.conf:99: unexpected end of input"
where 99 is the last line of named.conf.
A: There are unbalanced quotes in named.conf.
A: Some text editors (notepad and wordpad) fail to put a line title
indication (e.g. CR/LF) on the last line of a text file. This can be
fixed by "adding" a blank line to the end of the file. Named expects to
see EOF immediately after EOL and treats text files where this is not
met as truncated.
Q: How do I share a dynamic zone between multiple views?
A: You choose one view to be master and the second a slave and transfer
the zone between views.
Master 10.0.1.1:
key "external" {
algorithm hmac-sha256;
secret "xxxxxxxxxxxxxxxxxxxxxxxx";
};
key "mykey" {
algorithm hmac-sha256;
secret "yyyyyyyyyyyyyyyyyyyyyyyy";
};
view "internal" {
match-clients { !key external; 10.0.1/24; };
server 10.0.1.1 {
/* Deliver notify messages to external view. */
keys { external; };
};
zone "example.com" {
type master;
file "internal/example.db";
allow-update { key mykey; };
also-notify { 10.0.1.1; };
};
};
view "external" {
match-clients { key external; any; };
zone "example.com" {
type slave;
file "external/example.db";
masters { 10.0.1.1; };
transfer-source 10.0.1.1;
// allow-update-forwarding { any; };
// allow-notify { ... };
};
};
Q: I get a error message like "zone wireless.ietf56.ietf.org/IN: loading
master file primaries/wireless.ietf56.ietf.org: no owner".
A: This error is produced when a line in the master file contains leading
white space (tab/space) but the is no current record owner name to
inherit the name from. Usually this is the result of putting white
space before a comment, forgetting the "@" for the SOA record, or
indenting the master file.
Q: Why are my logs in GMT (UTC).
A: You are running chrooted (-t) and have not supplied local timezone
information in the chroot area.
FreeBSD: /etc/localtime
Solaris: /etc/TIMEZONE and /usr/share/lib/zoneinfo
OSF: /etc/zoneinfo/localtime
See also tzset(3) and zic(8).
Q: I get "rndc: connect failed: connection refused" when I try to run
rndc.
A: This is usually a configuration error.
First ensure that named is running and no errors are being reported at
startup (/var/log/messages or equivalent). Running "named -g <usual
arguments>" from a title can help at this point.
Secondly ensure that named is configured to use rndc either by
"rndc-confgen -a", rndc-confgen or manually. The Administrators
Reference manual has details on how to do this.
Old versions of rndc-confgen used localhost rather than 127.0.0.1 in /
etc/rndc.conf for the default server. Update /etc/rndc.conf if
necessary so that the default server listed in /etc/rndc.conf matches
the addresses used in named.conf. "localhost" has two address
(127.0.0.1 and ::1).
If you use "rndc-confgen -a" and named is running with -t or -u ensure
that /etc/rndc.conf has the correct ownership and that a copy is in the
chroot area. You can do this by re-running "rndc-confgen -a" with
appropriate -t and -u arguments.
Q: I get "transfer of 'example.net/IN' from 192.168.4.12#53: failed while
receiving responses: permission denied" error messages.
A: These indicate a filesystem permission error preventing named creating
/ renaming the temporary file. These will usually also have other
associated error messages like
"dumping master file: sl/tmp-XXXX5il3sQ: open: permission denied"
Named needs write permission on the directory containing the file.
Named writes the new cache file to a temporary file then renames it to
the name specified in named.conf to ensure that the contents are always
complete. This is to prevent named loading a partial zone in the event
of power failure or similar interrupting the write of the master file.
Note file names are relative to the directory specified in options and
any chroot directory ([<chroot dir>/][<options dir>]).
If named is invoked as "named -t /chroot/DNS" with the following
named.conf then "/chroot/DNS/var/named/sl" needs to be writable by the
user named is running as.
options {
directory "/var/named";
};
zone "example.net" {
type slave;
file "sl/example.net";
masters { 192.168.4.12; };
};
Q: I want to forward all DNS queries from my caching nameserver to another
server. But there are some domains which have to be served locally, via
rbldnsd.
How do I achieve this ?
A: options {
forward only;
forwarders { <ip.of.primary.nameserver>; };
};
zone "sbl-xbl.spamhaus.org" {
type forward; forward only;
forwarders { <ip.of.rbldns.server> port 530; };
};
zone "list.dsbl.org" {
type forward; forward only;
forwarders { <ip.of.rbldns.server> port 530; };
};
Q: Can you help me understand how BIND 9 uses memory to store DNS zones?
Some times it seems to take several times the amount of memory it needs
to store the zone.
A: When reloading a zone named my have multiple copies of the zone in
memory at one time. The zone it is serving and the one it is loading.
If reloads are ultra fast it can have more still.
e.g. Ones that are transferring out, the one that it is serving and the
one that is loading.
BIND 8 destroyed the zone before loading and also killed off outgoing
transfers of the zone.
The new strategy allows slaves to get copies of the new zone regardless
of how often the master is loaded compared to the transfer time. The
slave might skip some intermediate versions but the transfers will
complete and it will keep reasonably in sync with the master.
The new strategy also allows the master to recover from syntax and
other errors in the master file as it still has an in-core copy of the
old contents.
Q: I want to use IPv6 locally but I don't have a external IPv6 connection.
External lookups are slow.
A: You can use server clauses to stop named making external lookups over
IPv6.
server fd81:ec6c:bd62::/48 { bogus no; }; // site ULA prefix
server ::/0 { bogus yes; };
3. Operations Questions
Q: How to change the nameservers for a zone?
A: Step 1: Ensure all nameservers, new and old, are serving the same zone
content.
Step 2: Work out the maximum TTL of the NS RRset in the parent and
child zones. This is the time it will take caches to be clear of a
particular version of the NS RRset. If you are just removing
nameservers you can skip to Step 6.
Step 3: Add new nameservers to the NS RRset for the zone and wait until
all the servers for the zone are answering with this new NS RRset.
Step 4: Inform the parent zone of the new NS RRset then wait for all
the parent servers to be answering with the new NS RRset.
Step 5: Wait for cache to be clear of the old NS RRset. See Step 2 for
how long. If you are just adding nameservers you are done.
Step 6: Remove any old nameservers from the zones NS RRset and wait for
all the servers for the zone to be serving the new NS RRset.
Step 7: Inform the parent zone of the new NS RRset then wait for all
the parent servers to be answering with the new NS RRset.
Step 8: Wait for cache to be clear of the old NS RRset. See Step 2 for
how long.
Step 9: Turn off the old nameservers or remove the zone entry from the
configuration of the old nameservers.
Step 10: Increment the serial number and wait for the change to be
visible in all nameservers for the zone. This ensures that zone
transfers are still working after the old servers are decommissioned.
Note: the above procedure is designed to be transparent to dns clients.
Decommissioning the old servers too early will result in some clients
not being able to look up answers in the zone.
Note: while it is possible to run the addition and removal stages
together it is not recommended.
4. General Questions
Q: I keep getting log messages like the following. Why?
Dec 4 23:47:59 client 10.0.0.1#1355: updating zone 'example.com/IN':
update failed: 'RRset exists (value dependent)' prerequisite not
satisfied (NXRRSET)
A: DNS updates allow the update request to test to see if certain
conditions are met prior to proceeding with the update. The message
above is saying that conditions were not met and the update is not
proceeding. See doc/rfc/rfc2136.txt for more details on prerequisites.
Q: I keep getting log messages like the following. Why?
Jun 21 12:00:00.000 client 10.0.0.1#1234: update denied
A: Someone is trying to update your DNS data using the RFC2136 Dynamic
Update protocol. Windows 2000 machines have a habit of sending dynamic
update requests to DNS servers without being specifically configured to
do so. If the update requests are coming from a Windows 2000 machine,
see <http://support.microsoft.com/support/kb/articles/q246/8/04.asp>
for information about how to turn them off.
Q: When I do a "dig . ns", many of the A records for the root servers are
missing. Why?
A: This is normal and harmless. It is a somewhat confusing side effect of
the way BIND 9 does RFC2181 trust ranking and of the efforts BIND 9
makes to avoid promoting glue into answers.
When BIND 9 first starts up and primes its cache, it receives the root
server addresses as additional data in an authoritative response from a
root server, and these records are eligible for inclusion as additional
data in responses. Subsequently it receives a subset of the root server
addresses as additional data in a non-authoritative (referral) response
from a root server. This causes the addresses to now be considered
non-authoritative (glue) data, which is not eligible for inclusion in
responses.
The server does have a complete set of root server addresses cached at
all times, it just may not include all of them as additional data,
depending on whether they were last received as answers or as glue. You
can always look up the addresses with explicit queries like "dig
a.root-servers.net A".
Q: Why don't my zones reload when I do an "rndc reload" or SIGHUP?
A: A zone can be updated either by editing zone files and reloading the
server or by dynamic update, but not both. If you have enabled dynamic
update for a zone using the "allow-update" option, you are not supposed
to edit the zone file by hand, and the server will not attempt to
reload it.
Q: Why is named listening on UDP port other than 53?
A: Named uses a system selected port to make queries of other nameservers.
This behaviour can be overridden by using query-source to lock down the
port and/or address. See also notify-source and transfer-source.
Q: I get warning messages like "zone example.com/IN: refresh: failure
trying master 1.2.3.4#53: timed out".
A: Check that you can make UDP queries from the slave to the master
dig +norec example.com soa @1.2.3.4
You could be generating queries faster than the slave can cope with.
Lower the serial query rate.
serial-query-rate 5; // default 20
Q: I don't get RRSIG's returned when I use "dig +dnssec".
A: You need to ensure DNSSEC is enabled (dnssec-enable yes;).
Q: Can a NS record refer to a CNAME.
A: No. The rules for glue (copies of the *address* records in the parent
zones) and additional section processing do not allow it to work.
You would have to add both the CNAME and address records (A/AAAA) as
glue to the parent zone and have CNAMEs be followed when doing
additional section processing to make it work. No nameserver
implementation supports either of these requirements.
Q: What does "RFC 1918 response from Internet for 0.0.0.10.IN-ADDR.ARPA"
mean?
A: If the IN-ADDR.ARPA name covered refers to a internal address space you
are using then you have failed to follow RFC 1918 usage rules and are
leaking queries to the Internet. You should establish your own zones
for these addresses to prevent you querying the Internet's name servers
for these addresses. Please see <http://as112.net/> for details of the
problems you are causing and the counter measures that have had to be
deployed.
If you are not using these private addresses then a client has queried
for them. You can just ignore the messages, get the offending client to
stop sending you these messages as they are most probably leaking them
or setup your own zones empty zones to serve answers to these queries.
zone "10.IN-ADDR.ARPA" {
type master;
file "empty";
};
zone "16.172.IN-ADDR.ARPA" {
type master;
file "empty";
};
...
zone "31.172.IN-ADDR.ARPA" {
type master;
file "empty";
};
zone "168.192.IN-ADDR.ARPA" {
type master;
file "empty";
};
empty:
@ 10800 IN SOA <name-of-server>. <contact-email>. (
1 3600 1200 604800 10800 )
@ 10800 IN NS <name-of-server>.
Note
Future versions of named are likely to do this automatically.
Q: Will named be affected by the 2007 changes to daylight savings rules in
the US.
A: No, so long as the machines internal clock (as reported by "date -u")
remains at UTC. The only visible change if you fail to upgrade your OS,
if you are in a affected area, will be that log messages will be a hour
out during the period where the old rules do not match the new rules.
For most OS's this change just means that you need to update the
conversion rules from UTC to local time. Normally this involves
updating a file in /etc (which sets the default timezone for the
machine) and possibly a directory which has all the conversion rules
for the world (e.g. /usr/share/zoneinfo). When updating the OS do not
forget to update any chroot areas as well. See your OS's documentation
for more details.
The local timezone conversion rules can also be done on a individual
basis by setting the TZ environment variable appropriately. See your
OS's documentation for more details.
Q: Is there a bugzilla (or other tool) database that mere mortals can have
(read-only) access to for bind?
A: No. The BIND 9 bug database is kept closed for a number of reasons.
These include, but are not limited to, that the database contains
proprietory information from people reporting bugs. The database has in
the past and may in future contain unfixed bugs which are capable of
bringing down most of the Internet's DNS infrastructure.
The release pages for each version contain up to date lists of bugs
that have been fixed post release. That is as close as we can get to
providing a bug database.
Q: Why do queries for NSEC3 records fail to return the NSEC3 record?
A: NSEC3 records are strictly meta data and can only be returned in the
authority section. This is done so that signing the zone using NSEC3
records does not bring names into existence that do not exist in the
unsigned version of the zone.
5. Operating-System Specific Questions
5.1. HPUX
Q: I get the following error trying to configure BIND:
checking if unistd.h or sys/types.h defines fd_set... no
configure: error: need either working unistd.h or sys/select.h
A: You have attempted to configure BIND with the bundled C compiler. This
compiler does not meet the minimum compiler requirements to for
building BIND. You need to install a ANSI C compiler and / or teach
configure how to find the ANSI C compiler. The later can be done by
adjusting the PATH environment variable and / or specifying the
compiler via CC.
./configure CC=<compiler> ...
5.2. Linux
Q: Why do I get the following errors:
general: errno2result.c:109: unexpected error:
general: unable to convert errno to isc_result: 14: Bad address
client: UDP client handler shutting down due to fatal receive error: unexpected error
A: This is the result of a Linux kernel bug.
See: <http://marc.theaimsgroup.com/?l=linux-netdev&m=113081708031466&w=
2>
Q: Why does named lock up when it attempts to connect over IPSEC tunnels?
A: This is due to a kernel bug where the fact that a socket is marked
non-blocking is ignored. It is reported that setting xfrm_larval_drop
to 1 helps but this may have negative side effects. See: <https://
bugzilla.redhat.com/show_bug.cgi?id=427629> and <http://lkml.org/lkml/
2007/12/4/260>.
xfrm_larval_drop can be set to 1 by the following procedure:
echo "1" > proc/sys/net/core/xfrm_larval_drop
Q: Why do I see 5 (or more) copies of named on Linux?
A: Linux threads each show up as a process under ps. The approximate
number of threads running is n+4, where n is the number of CPUs. Note
that the amount of memory used is not cumulative; if each process is
using 10M of memory, only a total of 10M is used.

the amount of memory used is not cumulative; if each process is using 10M of

Newer versions of Linux's ps command hide the individual threads and
require -L to display them.
Q: Why does BIND 9 log "permission denied" errors accessing its
configuration files or zones on my Linux system even though it is
running as root?
configuration files or zones on my Linux system even though it is running
as root?
A: On Linux, BIND 9 drops most of its root privileges on startup. This
including the privilege to open files owned by other users. Therefore,
if the server is running as root, the configuration files and zone
files should also be owned by root.
A: On Linux, BIND 9 drops most of its root privileges on startup.
This including the privilege to open files owned by other users.
Therefore, if the server is running as root, the configuration files
and zone files should also be owned by root.
Q: I get the error message "named: capset failed: Operation not permitted"
when starting named.
A: The capability module, part of "Linux Security Modules/LSM", has not
been loaded into the kernel. See insmod(8), modprobe(8).
Q: Why do I get errors like "dns_zone_load: zone foo/IN: loading master file
bar: ran out of space"
The relevant modules can be loaded by running:
A: This is often caused by TXT records with missing close quotes. Check that
all TXT records containing quoted strings have both open and close quotes.
modprobe commoncap
modprobe capability
Q: I'm running BIND on Red Hat Enterprise Linux or Fedora Core -
Q: How do I produce a usable core file on Linux?
Why can't named update slave zone database files?
A: Apply the kernel patch found in bind9/linux/coredump-patch and rebuild
the kernel. This patch causes multithreaded programs to dump the correct
thread.
Why can't named create DDNS journal files or update the master zones
from journals?
Why can't named create custom log files?
Q: How do I restrict people from looking up the server version?
A: Red Hat Security Enhanced Linux (SELinux) policy security protections :
A: Put a "version" option containing something other than the real
version in the "options" section of named.conf. Note doing this will
not prevent attacks and may impede people trying to diagnose problems
with your server. Also it is possible to "fingerprint" nameservers to
determine their version.
Red Hat have adopted the National Security Agency's SELinux security
policy (see <http://www.nsa.gov/selinux>) and recommendations for BIND
security , which are more secure than running named in a chroot and
make use of the bind-chroot environment unnecessary .
By default, named is not allowed by the SELinux policy to write, create
or delete any files EXCEPT in these directories:
Q: How do I restrict only remote users from looking up the server
version?
$ROOTDIR/var/named/slaves
$ROOTDIR/var/named/data
$ROOTDIR/var/tmp
A: The following view statement will intercept lookups as the internal
view that holds the version information will be matched last. The
caveats of the previous answer still apply, of course.
view "chaos" chaos {
match-clients { <those to be refused>; };
allow-query { none; };
zone "." {
type hint;
file "/dev/null"; // or any empty file
};
};
where $ROOTDIR may be set in /etc/sysconfig/named if bind-chroot is
installed.
The SELinux policy particularly does NOT allow named to modify the
$ROOTDIR/var/named directory, the default location for master zone
database files.
Q: What do "no source of entropy found" or "could not open entropy source foo"
mean?
SELinux policy overrules file access permissions - so even if all the
files under /var/named have ownership named:named and mode rw-rw-r--,
named will still not be able to write or create files except in the
directories above, with SELinux in Enforcing mode.
A: The server requires a source of entropy to perform certain operations,
mostly DNSSEC related. These messages indicate that you have no source
of entropy. On systems with /dev/random or an equivalent, it is used by
default. A source of entropy can also be defined using the random-device
option in named.conf.
So, to allow named to update slave or DDNS zone files, it is best to
locate them in $ROOTDIR/var/named/slaves, with named.conf zone
statements such as:
zone "slave.zone." IN {
type slave;
file "slaves/slave.zone.db";
...
};
zone "ddns.zone." IN {
type master;
allow-updates {...};
file "slaves/ddns.zone.db";
};
Q: I installed BIND 9 and restarted named, but it's still BIND 8. Why?
A: BIND 9 is installed under /usr/local by default. BIND 8 is often
installed under /usr. Check that the correct named is running.
To allow named to create its cache dump and statistics files, for
example, you could use named.conf options statements such as:
options {
...
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
...
};
Q: I'm trying to install on AIX and compilation is failing with
errors like
"confparser.c", line 8244.1: 1506-343 (S) Redeclaration of
token_to_keyword differs from previous declaration on line 348 of
"confparser.c".
You can also tell SELinux to allow named to update any zone database
files, by setting the SELinux tunable boolean parameter
'named_write_master_zones=1', using the system-config-securitylevel
GUI, using the 'setsebool' command, or in /etc/selinux/targeted/
booleans.
A: You probably have a buggy version of GNU bison installed on your
system. Remove bison it from your path, remove the config.cache file,
and rerun configure so that it picks up the AIX yacc instead.
You can disable SELinux protection for named entirely by setting the
'named_disable_trans=1' SELinux tunable boolean parameter.
The SELinux named policy defines these SELinux contexts for named:
Q: I'm trying to use TSIG to authenticate dynamic updates or zone
transfers. I'm sure I have the keys set up correctly, but the server
is rejecting the TSIG. Why?
named_zone_t : for zone database files - $ROOTDIR/var/named/*
named_conf_t : for named configuration files - $ROOTDIR/etc/{named,rndc}.*
named_cache_t: for files modifiable by named - $ROOTDIR/var/{tmp,named/{slaves,data}}
A: This may be a clock skew problem. Check that the the clocks on
the client and server are properly synchronized (e.g., using ntp).
If you want to retain use of the SELinux policy for named, and put
named files in different locations, you can do so by changing the
context of the custom file locations .
Q: I'm trying to compile BIND 9, and "make" is failing due to files not
being found. Why?
To create a custom configuration file location, e.g. '/root/
named.conf', to use with the 'named -c' option, do:
A: Using a parallel or distributed "make" to build BIND 9 is not
supported, and doesn't work. If you are using one of these, use
normal make or gmake instead.
# chcon system_u:object_r:named_conf_t /root/named.conf
Q: I have a BIND 9 master and a BIND 8.2.3 slave, and the master is
logging error messages like "notify to 10.0.0.1#53 failed: unexpected
end of input". What's wrong?
To create a custom modifiable named data location, e.g. '/var/log/
named' for a log file, do:
# chcon system_u:object_r:named_cache_t /var/log/named
To create a custom zone file location, e.g. /root/zones/, do:
# chcon system_u:object_r:named_zone_t /root/zones/{.,*}
See these man-pages for more information : selinux(8), named_selinux
(8), chcon(1), setsebool(8)
Q: I'm running BIND on Ubuntu -
Why can't named update slave zone database files?
Why can't named create DDNS journal files or update the master zones
from journals?
Why can't named create custom log files?
A: Ubuntu uses AppArmor <http://en.wikipedia.org/wiki/AppArmor> in
addition to normal file system permissions to protect the system.
Adjust the paths to use those specified in /etc/apparmor.d/
usr.sbin.named or adjust /etc/apparmor.d/usr.sbin.named to allow named
to write at the location specified in named.conf.
Q: Listening on individual IPv6 interfaces does not work.
A: This is usually due to "/proc/net/if_inet6" not being available in the
chroot file system. Mount another instance of "proc" in the chroot file
system.
This can be be made permanent by adding a second instance to /etc/
fstab.
proc /proc proc defaults 0 0
proc /var/named/proc proc defaults 0 0
5.3. Windows
Q: Zone transfers from my BIND 9 master to my Windows 2000 slave fail.
Why?
A: This may be caused by a bug in the Windows 2000 DNS server where DNS
messages larger than 16K are not handled properly. This can be worked
around by setting the option "transfer-format one-answer;". Also check
whether your zone contains domain names with embedded spaces or other
special characters, like "John\032Doe\213s\032Computer", since such
names have been known to cause Windows 2000 slaves to incorrectly
reject the zone.
Q: I get "Error 1067" when starting named under Windows.
A: This is the service manager saying that named exited. You need to
examine the Application log in the EventViewer to find out why.
Common causes are that you failed to create "named.conf" (usually "C:\
windows\dns\etc\named.conf") or failed to specify the directory in
named.conf.
options {
Directory "C:\windows\dns\etc";
};
5.4. FreeBSD
Q: I have FreeBSD 4.x and "rndc-confgen -a" just sits there.
A: /dev/random is not configured. Use rndcontrol(8) to tell the kernel to
use certain interrupts as a source of random events. You can make this
permanent by setting rand_irqs in /etc/rc.conf.
rand_irqs="3 14 15"
See also <http://people.freebsd.org/~dougb/randomness.html>.
5.5. Solaris
Q: How do I integrate BIND 9 and Solaris SMF
A: Sun has a blog entry describing how to do this.
<http://blogs.sun.com/roller/page/anay/Weblog?catname=%2FSolaris>
5.6. Apple Mac OS X
Q: How do I run BIND 9 on Apple Mac OS X?
A: If you run Tiger(Mac OS 10.4) or later then this is all you need to do:
% sudo rndc-confgen > /etc/rndc.conf
Copy the key statement from /etc/rndc.conf into /etc/rndc.key, e.g.:
key "rndc-key" {
algorithm hmac-md5;
secret "uvceheVuqf17ZwIcTydddw==";
};
Then start the relevant service:
% sudo service org.isc.named start
This is persistent upon a reboot, so you will have to do it only once.
A: Alternatively you can just generate /etc/rndc.key by running:
% sudo rndc-confgen -a
Then start the relevant service:
% sudo service org.isc.named start
Named will look for /etc/rndc.key when it starts if it doesn't have a
controls section or the existing controls are missing keys sub-clauses.
This is persistent upon a reboot, so you will have to do it only once.
A: This error message is caused by a known bug in BIND 8.2.3 and will
be fixed in 8.2.4. It can be safely ignored - the notify has been
acted on by the slave despite the error message.

BIND 9.7.0
BIND 9.7.0 includes a number of changes from BIND 9.6 and earlier
releases. Most are intended to simplify DNSSEC configuration.
New features include:
BIND 9.1.3
- Fully automatic signing of zones by "named".
- Simplified configuration of DNSSEC Lookaside Validation (DLV).
- Simplified configuration of Dynamic DNS, using the "ddns-confgen"
command line tool or the "local" update-policy option. (As a side
effect, this also makes it easier to configure automatic zone
re-signing.)
- New named option "attach-cache" that allows multiple views to
share a single cache.
- DNS rebinding attack prevention.
- New default values for dnssec-keygen parameters.
- Support for RFC 5011 automated trust anchor maintenance
(see README.rfc5011 for additional details).
- Smart signing: simplified tools for zone signing and key
maintenance.
- The "statistics-channels" option is now available on Windows.
- A new DNSSEC-aware libdns API for use by non-BIND9 applications
(see README.libdns for details).
- On some platforms, named and other binaries can now print out
a stack backtrace on assertion failure, to aid in debugging.
- A "tools only" installation mode on Windows, which only installs
dig, host, nslookup and nsupdate.
- Improved PKCS#11 support, including Keyper support and explicit
OpenSSL engine selection (see README.pkcs11 for additional details).
BIND 9.1.3 is a maintenance release, containing fixes for
a number of bugs in 9.1.2 but no new features.
COMPATIBILITY NOTES:
Features introduced in 9.1.0 included:
- If you had built BIND 9.6 with any of ALLOW_NSEC3PARAM_UPDATE,
ALLOW_SECURE_TO_INSECURE or ALLOW_INSECURE_TO_SECURE defined, then
you should ensure that all changes that are in progress have
completed prior to upgrading to BIND 9.7. BIND 9.7 implements
those features in a way which is not backwards compatible.
- Many BIND 8 features previously unimplemented in BIND 9,
including domain-specific forwarding, the $GENERATE
master file directive, and the "blackhole", "dialup",
and "sortlist" options
- Prior releases had a bug which caused HMAC-SHA* keys with long
secrets to be used incorrectly. Fixing this bug means that older
versions of BIND 9 may fail to interoperate with this version
when using TSIG keys. If this occurs, the new "isc-hmac-fixup"
tool will convert a key with a long secret into a form that works
correctly with all versions of BIND 9. See the "isc-hmac-fixup"
man page for additional details.
- Forwarding of dynamic update requests; this is enabled
by the "allow-update-forwarding" option
- Revoking a DNSSEC key with "dnssec-revoke" changes its key ID.
It is possible for the new key ID to collide with that of a
different key. Newly generated keys will not have this problem,
as "dnssec-keygen" looks for potential collisions before
generating keys, but exercise caution if using key revokation
with keys that were generated by older versions of BIND 9.
See README.rfc5011 for more details.
- A bug was fixed in which a key's scheduled inactivity date was
stored incorectly. Users who participated in the 9.7.0 BETA
test and had DNSSEC keys with scheduled inactivity dates will
need to reset those keys' dates using "dnssec-settime -I".
- A new, simplified database interface and a number of
sample drivers based on it; see doc/misc/sdb for details
BIND 9.6.0
- Support for building single-threaded servers for
environments that do not supply POSIX threads
BIND 9.6.0 includes a number of changes from BIND 9.5 and earlier
releases, including:
- New configuration options: "min-refresh-time",
"max-refresh-time", "min-retry-time", "max-retry-time",
"additional-from-auth", "additional-from-cache",
"notify explicit"
Full NSEC3 support
- Faster lookups, particularly in large zones.
Automatic zone re-signing
BIND 9.1 also includes experimental implementations of a
number of DNS protocols extensions still under development
in the IETF. These include transparent processing of
unknown RR types and use of the EDNS "DNSSEC OK" bit to
explicitly enable DNSSEC processing in responses.
New update-policy methods tcp-self and 6to4-self
Cryptographic operations are now based on the OpenSSL
library instead of DNSsafe.
The BIND 8 resolver library, libbind, has been removed from the
BIND 9 distribution and is now available as a separate download.
BIND 9.1 is primarily a name server software distribution.
In addition to the name server, it also includes a new
lightweight stub resolver library and associated resolver
daemon that fully support forward and reverse lookups of both
IPv4 and IPv6 addresses. This library is still considered
experimental and is not a complete replacement for the BIND 8
resolver library. Applications that use the BIND 8 res_*
functions to perform DNS lookups or dynamic updates still need
to be linked against the BIND 8 libraries. For DNS lookups,
they can also use the new "getrrsetbyname()" API.
Change the default pid file location from /var/run to
/var/run/{named,lwresd} for improved chroot/setuid support.
BIND 9.5.0
BIND 9.5.0 has a number of new features over 9.4,
including:
GSS-TSIG support (RFC 3645).
DHCID support.
Experimental http server and statistics support for named via xml.
More detailed statistics counters including those supported in BIND 8.
Faster ACL processing.
Use Doxygen to generate internal documentation.
Efficient LRU cache-cleaning mechanism.
NSID support.
BIND 9.4.0
BIND 9.4.0 has a number of new features over 9.3,
including:
Implemented "additional section caching (or acache)", an
internal cache framework for additional section content to
improve response performance. Several configuration options
were provided to control the behavior.
New notify type 'master-only'. Enable notify for master
zones only.
Accept 'notify-source' style syntax for query-source.
rndc now allows addresses to be set in the server clauses.
New option "allow-query-cache". This lets "allow-query"
be used to specify the default zone access level rather
than having to have every zone override the global value.
"allow-query-cache" can be set at both the options and view
levels. If "allow-query-cache" is not set then "allow-recursion"
is used if set, otherwise "allow-query" is used if set
unless "recursion no;" is set in which case "none;" is used,
otherwise the default (localhost; localnets;) is used.
rndc: the source address can now be specified.
ixfr-from-differences now takes master and slave in addition

libbind: corresponds to that from BIND 8.4.5.
BIND 9.2.0
BIND 9.2.0 has a number of new features over 9.1,
including:
- The size of the cache can now be limited using the
"max-cache-size" option.
- The server can now automatically convert RFC1886-style
recursive lookup requests into RFC2874-style lookups,
when enabled using the new option "allow-v6-synthesis".
This allows stub resolvers that support AAAA records
but not A6 record chains or binary labels to perform
lookups in domains that make use of these IPv6 DNS
features.
- Performance has been improved.
- The man pages now use the more portable "man" macros
rather than the "mandoc" macros, and are installed
by "make install".
- The named.conf parser has been completely rewritten.
It now supports "include" directives in more
places such as inside "view" statements, and it no
longer has any reserved words.
- The "rndc status" command is now implemented.
- rndc can now be configured automatically.
- A BIND 8 compatible stub resolver library is now
included in lib/bind.
- OpenSSL has been removed from the distribution. This
means that to use DNSSEC, OpenSSL must be installed and
the --with-openssl option must be supplied to configure.
This does not apply to the use of TSIG, which does not
require OpenSSL.
- The source distribution now builds on Windows.
See win32utils/readme1.txt and win32utils/win32-build.txt
for details.
This distribution also includes a new lightweight stub
resolver library and associated resolver daemon that fully
support forward and reverse lookups of both IPv4 and IPv6
addresses. This library is considered experimental and
is not a complete replacement for the BIND 8 resolver library.
Applications that use the BIND 8 res_* functions to perform
DNS lookups or dynamic updates still need to be linked against
the BIND 8 libraries. For DNS lookups, they can also use the
new "getrrsetbyname()" API.

DNSSEC and Dynamic Zones
As of BIND 9.7.0 it is possible to change a dynamic zone from
insecure to secure and back again. A secure zone can use either
NSEC or NSEC3 chains.
Converting from insecure to secure
Changing a zone from insecure to secure can be done in two ways:
using a dynamic DNS update, or the "auto-dnssec" zone option.
For either method, you need to configure named so that it can see
the K* files which contain the public and private parts of the keys
that will be used to sign the zone. These files will have been
generated by dnssec-keygen. You can do this by placing them in
the key-directory, as specified in named.conf:
zone example.net {
type master;
update-policy local;
file "dynamic/example.net/example.net";
key-directory "dynamic/example.net";
};
If one KSK and one ZSK DNSKEY key have been generated, this configuration
will cause all records in the zone to be signed with the ZSK, and the
DNSKEY RRset to be signed with the KSK as well. An NSEC chain will be
generated as part of the initial signing process.
Dynamic DNS update method
To insert the keys via dynamic update:
% nsupdate
> ttl 3600
> update add example.net DNSKEY 256 3 7 AwEAAZn17pUF0KpbPA2c7Gz76Vb18v0teKT3EyAGfBfL8eQ8al35zz3Y I1m/SAQBxIqMfLtIwqWPdgthsu36azGQAX8=
> update add example.net DNSKEY 257 3 7 AwEAAd/7odU/64o2LGsifbLtQmtO8dFDtTAZXSX2+X3e/UNlq9IHq3Y0 XtC0Iuawl/qkaKVxXe2lo8Ct+dM6UehyCqk=
> send
While the update request will complete almost immediately, the zone
will not be completely signed until named has had time to walk the
zone and generate the NSEC and RRSIG records. The NSEC record at the
apex will be added last, to signal that there is a complete NSEC chain.
If you wish to sign using NSEC3 instead of NSEC, you should add an
NSEC3PARAM record to the initial update request. If you wish the
NSEC3 chain to have the OPTOUT bit set, set it in the flags field
of the NSEC3PARAM record.
% nsupdate
> ttl 3600
> update add example.net DNSKEY 256 3 7 AwEAAZn17pUF0KpbPA2c7Gz76Vb18v0teKT3EyAGfBfL8eQ8al35zz3Y I1m/SAQBxIqMfLtIwqWPdgthsu36azGQAX8=

> update add example.net NSEC3PARAM 1 1 100 1234567890
> send
Again, this update request will complete almost immediately; however,
the record won't show up until named has had a chance to build/remove
the relevant chain. A private type record will be created to record
the state of the operation (see below for more details), and will be
removed once the operation completes.
While the initial signing and NSEC/NSEC3 chain generation is happening,
other updates are possible as well.
Fully automatic zone signing
To enable automatic signing, add the "auto-dnssec" option to the zone
statement in named.conf. "auto-dnssec" has two possible arguments:
"allow" or "maintain".
With "auto-dnssec allow", named can search the key directory for keys
matching the zone, insert them into the zone, and use them to sign the
zone. It will do so only when it receives an "rndc sign <zonename>"
command.
"auto-dnssec maintain" includes the above functionality, but will also
automatically adjust the zone's DNSKEY records on schedule according to the
keys' timing metadata (see the man pages for dnssec-keygen and
dnssec-settime for more information). If keys are present in the key
directory the first time the zone is loaded, it will be signed
immediately, without waiting for an "rndc sign" command. (This
command can still be used for unscheduled key changes, however.)
Using the "auto-dnssec" option requires the zone to be configured to
allow dynamic updates, by adding an "allow-update" or "update-policy"
statement to the zone configuration. If this has not been done, the
configuration will fail.
Private-type records
The state of the signing process is signaled by private-type records
(with a default type value of 65534). When signing is complete, these
records will have a nonzero value for the final octet (for those records
which have a nonzero initial octet).
The private type record format:
If the first octet is non-zero then the record indicates that the zone needs
to be signed with the key matching the record, or that all signatures that
match the record should be removed.
algorithm (octet 1)
key id in network order (octet 2 and 3)
removal flag (octet 4)
complete flag (octet 5)
Only records flagged as "complete" can be removed via dynamic update.
Attempts to remove other private type records will be silently ignored.
If the first octet is zero (this is a reserved algorithm number
that should never appear in a DNSKEY record) then the record indicates
changes to the NSEC3 chains are in progress. The rest of the record
contains an NSEC3PARAM record. The flag field tells what operation
to perform based on the flag bits.
0x01 OPTOUT
0x80 CREATE
0x40 REMOVE
0x20 NONSEC
DNSKEY rollovers via UPDATE
It is possible to perform key rollovers via dynamic update. You need
to add the K* files for the new keys so that named can find them. You
can then add the new DNSKEY RRs via dynamic update. Named will then cause
the zone to be signed with the new keys. When the signing is
complete the private type records will be updated so that the last
octet is non zero.
If this is for a KSK you need to inform the parent and any trust
anchor repositories of the new KSK.
You should then wait for the maximum TTL in the zone before removing the
old DNSKEY. If it is a KSK that is being updated, you also need to wait
for the DS RRset in the parent to be updated and its TTL to expire.
This ensures that all clients will be able to verify at least one
signature when you remove the old DNSKEY.
The old DNSKEY can be removed via UPDATE. Take care to specify
the correct key. Named will clean out any signatures generated by
the old key after the update completes.
NSEC3PARAM rollovers via UPDATE
Add the new NSEC3PARAM record via dynamic update. When the new NSEC3 chain
has been generated, the NSEC3PARAM flag field will be zero. At this
point you can remove the old NSEC3PARAM record. The old chain will
be removed after the update request completes.
Converting from NSEC to NSEC3
To do this, you just need to add an NSEC3PARAM record. When the
conversion is complete, the NSEC chain will have been removed and
the NSEC3PARAM record will have a zero flag field. The NSEC3 chain
will be generated before the NSEC chain is destroyed.
Converting from NSEC3 to NSEC
To do this, remove all NSEC3PARAM records with a zero flag field. The
NSEC chain will be generated before the NSEC3 chain is removed.
Converting from secure to insecure
To do this, remove all the DNSKEY records. Any NSEC or NSEC3 chains
will be removed as well, along with associated NSEC3PARAM records.
This will take place after the update request completes. This
requires the "dnssec-secure-to-insecure" option to be set to "yes"
in named.conf.
Periodic re-signing
In any secure zone which supports dynamic updates, named will
periodically re-sign RRsets which have not been re-signed as
a result of some update action. The signature lifetimes will
be adjusted so as to spread the re-sign load over time rather than
all at once.
NSEC3 and OPTOUT
Named only supports creating new NSEC3 chains where all the NSEC3
records in the zone have the same OPTOUT state. Named supports
UPDATES to zones where the NSEC3 records in the chain have mixed
OPTOUT state. Named does not support changing the OPTOUT state of
an individual NSEC3 record, the entire chain needs to be changed if
the OPTOUT state of an individual NSEC3 needs to be changed.

BIND-9 DNS Library Support
This version of BIND9 "exports" its internal libraries so that they
can be used by third-party applications more easily (we call them
"export" libraries in this document). In addition to all major
DNS-related APIs BIND9 is currently using, the export libraries
provide the following features:
- The newly created "DNS client" module. This is a higher level API
that provides an interface to name resolution, single DNS
transaction with a particular server, and dynamic update. Regarding
name resolution, it supports advanced features such as DNSSEC
validation and caching. This module supports both synchronous and
asynchronous mode.
- The new "IRS" (Information Retrieval System) library. It provides
an interface to parse the traditional resolv.conf file and more
advanced, DNS-specific configuration file for the rest of this
package (see the description for the dns.conf file below).
- As part of the IRS library, newly implemented standard address-name
mapping functions, getaddrinfo() and getnameinfo(), are provided.
They use the DNSSEC-aware validating resolver backend, and could use
other advanced features of the BIND9 libraries such as caching. The
getaddrinfo() function resolves both A and AAAA RRs concurrently
(when the address family is unspecified).
- An experimental framework to support other event libraries than
BIND9's internal event task system.
* Prerequisite
GNU make is required to build the export libraries (other part of
BIND9 can still be built with other types of make). In the reminder
of this document, "make" means GNU make. Note that in some platforms
you may need to invoke a different command name than "make"
(e.g. "gmake") to indicate it's GNU make.
* Compilation
1. ./configure --enable-exportlib [other flags]
2. make
This will create (in addition to usual BIND9 programs) and a separate
set of libraries under the lib/export directory. For example,
lib/export/dns/libdns.a is the archive file of the export version of
the BIND9 DNS library.
Sample application programs using the libraries will also be built
under the lib/export/samples directory (see below).
* Installation
1. cd lib/export
2. make install (root privilege is normally required)
(make install at the top directory will do the same)
This will install library object files under the directory specified
by the --with-export-libdir configure option (default:
EPREFIX/lib/bind9), and header files under the directory specified by
the --with-export-includedir configure option (default:
PREFIX/include/bind9).
To see how to build your own application after the installation, see
lib/export/samples/Makefile-postinstall.in
* Known Defects/Restrictions
- Currently, win32 is not supported for the export library. (Normal
BIND9 application can be built as before).
- The "fixed" RRset order is not (currently) supported in the export
library. If you want to use "fixed" RRset order for, e.g. named
while still building the export library even without the fixed
order support, build them separately:
% ./configure --enable-fixed-rrset [other flags, but not --enable-exportlib]
% make (this doesn't have to be make)
% ./configure --enable-exportlib [other flags, but not --enable-fixed-rrset]
% cd lib/export
% make
- The client module and the IRS library currently do not support
DNSSEC validation using DLV (the underlying modules can handle it,
but there is no tunable interface to enable the feature).
- RFC5011 is not supported in the validating stub resolver of the
export library. In fact, it is not clear whether it should: trust
anchors would be a system-wide configuration which would be managed
by an administrator, while the stub resolver will be used by
ordinary applications run by a normal user.
- Not all common /etc/resolv.conf options are supported in the IRS library.
The only available options in this version are "debug" and "ndots".
* The dns.conf File
The IRS library supports an "advanced" configuration file related to
the DNS library for configuration parameters that would be beyond the
capability of the resolv.conf file. Specifically, it is intended to
provide DNSSEC related configuration parameters.
By default the path to this configuration file is /etc/dns.conf.
This module is very experimental and the configuration syntax or
library interfaces may change in future versions. Currently, only the
'trusted-keys' statement is supported, whose syntax is the same as the
same name of statement for named.conf.
* Sample Applications
Some sample application programs using this API are provided for
reference. The following is a brief description of these
applications.
- sample: a simple stub resolver utility.
It sends a query of a given name (of a given optional RR type)
to a specified recursive server, and prints the result as a list of
RRs. It can also act as a validating stub resolver if a trust
anchor is given via a set of command line options.
Usage: sample [options] server_address hostname
Options and Arguments:
-t RRtype
specify the RR type of the query. The default is the A RR.
[-a algorithm] [-e] -k keyname -K keystring
specify a command-line DNS key to validate the answer. For
example, to specify the following DNSKEY of example.com:
example.com. 3600 IN DNSKEY 257 3 5 xxx
specify the options as follows:
-e -k example.com -K "xxx"
-e means that this key is a zone's "key signing key" (as known
as "secure Entry point").
when -a is omitted rsasha1 will be used by default.
-s domain:alt_server_address
specify a separate recursive server address for the specific
"domain". Example: -s example.com:2001:db8::1234
server_address
an IP(v4/v6) address of the recursive server to which queries
are sent.
hostname
the domain name for the query
- sample-async: a simple stub resolver, working asynchronously.
Similar to "sample", but accepts a list of (query) domain names as a
separate file and resolves the names asynchronously.
Usage: sample-async [-s server_address] [-t RR_type] input_file
Options and Arguments:
-s server_address
an IPv4 address of the recursive server to which queries are
sent. (IPv6 addresses are not supported in this implementation)
-t RR_type
specify the RR type of the queries. The default is the A RR.
input_file
a list of domain names to be resolved. each line consists of a
single domain name. Example:
www.example.com
mx.examle.net
ns.xxx.example
- sample-request: a simple DNS transaction client.
It sends a query to a specified server, and prints the response with
minimal processing. It doesn't act as a "stub resolver": it stops
the processing once it gets any response from the server, whether
it's a referral or an alias (CNAME or DNAME) that would require
further queries to get the ultimate answer. In other words, this
utility acts as a very simplified dig.
Usage: sample-request [-t RRtype] server_address hostname
Options and Arguments:
-t RRtype
specify the RR type of the queries. The default is the A RR.
server_address
an IP(v4/v6) address of the recursive server to which the query is
sent.
hostname
the domain name for the query
- sample-gai: getaddrinfo() and getnameinfo() test code.
This is a test program to check getaddrinfo() and getnameinfo()
behavior. It takes a host name as an argument, calls getaddrinfo()
with the given host name, and calls getnameinfo() with the resulting
IP addresses returned by getaddrinfo(). If the dns.conf file exists
and defines a trust anchor, the underlying resolver will act as a
validating resolver, and getaddrinfo()/getnameinfo() will fail with
an EAI_INSECUREDATA error when DNSSEC validation fails.
Usage: sample-gai hostname
- sample-update: a simple dynamic update client program
It accepts a single update command as a command-line argument, sends
an update request message to the authoritative server, and shows the
response from the server. In other words, this is a simplified
nsupdate.
Usage: sample-update [options] (add|delete) "update data"
Options and Arguments:
-a auth_server
An IP address of the authoritative server that has authority
for the zone containing the update name. This should normally
be the primary authoritative server that accepts dynamic
updates. It can also be a secondary server that is configured
to forward update requests to the primary server.
-k keyfile
A TSIG key file to secure the update transaction. The keyfile
format is the same as that for the nsupdate utility.
-p prerequisite
A prerequisite for the update (only one prerequisite can be
specified). The prerequisite format is the same as that is
accepted by the nsupdate utility.
-r recursive_server
An IP address of a recursive server that this utility will
use. A recursive server may be necessary to identify the
authoritative server address to which the update request is
sent.
-z zonename
The domain name of the zone that contains
(add|delete)
Specify the type of update operation. Either "add" or "delete"
must be specified.
"update data"
Specify the data to be updated. A typical example of the data
would look like "name TTL RRtype RDATA".
Note: in practice, either -a or -r must be specified. Others can
be optional; the underlying library routine tries to identify the
appropriate server and the zone name for the update.
Examples: assuming the primary authoritative server of the
dynamic.example.com zone has an IPv6 address 2001:db8::1234,
+ sample-update -a sample-update -k Kxxx.+nnn+mmmm.key add "foo.dynamic.example.com 30 IN A 192.168.2.1"
adds an A RR for foo.dynamic.example.com using the given key.
+ sample-update -a sample-update -k Kxxx.+nnn+mmmm.key delete "foo.dynamic.example.com 30 IN A"
removes all A RRs for foo.dynamic.example.com using the given key.
+ sample-update -a sample-update -k Kxxx.+nnn+mmmm.key delete "foo.dynamic.example.com"
removes all RRs for foo.dynamic.example.com using the given key.
- nsprobe: domain/name server checker in terms of RFC4074.
It checks a set of domains to see the name servers of the domains
behave correctly in terms of RFC4074. This is included in the set
of sample programs to show how the export library can be used in a
DNS-related application.
Usage: nsprobe [-d] [-v [-v...]] [-c cache_address] [input_file]
Options
-d
run in the "debug" mode. with this option nsprobe will dump
every RRs it receives.
-v
increase verbosity of other normal log messages. This can be
specified multiple times
-c cache_address
specify an IP address of a recursive (caching) name server.
nsprobe uses this server to get the NS RRset of each domain and
the A and/or AAAA RRsets for the name servers. The default
value is 127.0.0.1.
input_file
a file name containing a list of domain (zone) names to be
probed. when omitted the standard input will be used. Each
line of the input file specifies a single domain name such as
"example.com". In general this domain name must be the apex
name of some DNS zone (unlike normal "host names" such as
"www.example.com"). nsprobe first identifies the NS RRsets for
the given domain name, and sends A and AAAA queries to these
servers for some "widely used" names under the zone;
specifically, adding "www" and "ftp" to the zone name.

BIND 9 PKCS #11 (Cryptoki) support
INTRODUCTION
PKCS #11 (Public Key Cryptography Standard #11) defines a platform-
independent API for the control of hardware security modules (HSMs)
and other cryptographic support devices.
BIND 9 is known to work with two HSMs: The Sun SCA 6000 cryptographic
acceleration board, tested under Solaris x86, and the AEP Keyper
network-attached key storage device, tested with Debian Linux,
Solaris x86 and Windows Server 2003.
PREREQUISITES
See the HSM vendor documentation for information about installing,
initializing, testing and troubleshooting the HSM.
BIND 9 uses OpenSSL for cryptography, but stock OpenSSL does not
yet fully support PKCS #11. However, a PKCS #11 engine for OpenSSL
is available from the OpenSolaris project. It has been modified by
ISC to work with with BIND 9, and to provide new features such as
PIN management and key by reference.
The patched OpenSSL depends on a "PKCS #11 provider". This is a shared
library object, providing a low-level PKCS #11 interface to the HSM
hardware. It is dynamically loaded by OpenSSL at runtime. The PKCS #11
provider comes from the HSM vendor, and and is specific to the HSM to be
controlled.
There are two "flavors" of PKCS #11 support provided by the patched
OpenSSL, one of which must be chosen at configuration time. The correct
choice depends on the HSM hardware:
- Use 'crypto-accelerator' with HSMs that have hardware cryptographic
acceleration features, such as the SCA 6000 board. This causes OpenSSL
to run all supported cryptographic operations in the HSM.
- Use 'sign-only' with HSMs that are designed to function primarily as
secure key storage devices, but lack hardware acceleration. These
devices are highly secure, but are not necessarily any faster at
cryptography than the system CPU--often, they are slower. It is
therefore most efficient to use them only for those cryptographic
functions that require access to the secured private key, such as
zone signing, and to use the system CPU for all other computationally-
intensive operations. The AEP Keyper is an example of such a device.
The modified OpenSSL code is included in the BIND 9.7.0b1 release, in the
form of a context diff against OpenSSL 0.9.8l. Before building BIND 9
with PKCS #11 support, it will be necessary to build OpenSSL with this
patch in place and inform it of the path to the HSM-specific PKCS #11
provider library.
Obtain OpenSSL 0.9.8l:
wget http://www.openssl.org/source/openssl-0.9.8l.tar.gz
Extract the tarball:
tar zxf openssl-0.9.8l.tar.gz
Apply the patch from the BIND 9 release:
patch -p1 -d openssl-0.9.8l \
< bind-9.7.0b1/bin/pkcs11/openssl-0.9.8l-patch
(Note that the patch file may not be compatible with the "patch"
utility on all operating systems. You may need to install GNU patch.)
When building OpenSSL, place it in a non-standard location so that it
does not interfere with OpenSSL libraries elsewhere on the system.
In the following examples, we choose to install into "/opt/pkcs11/usr".
We will use this location when we configure BIND 9.
EXAMPLE 1--BUILDING OPENSSL FOR THE AEP KEYPER ON LINUX:
The AEP Keyper is a highly secure key storage device, but does
not provide hardware cryptographic acceleration. It can carry out
cryptographic operations, but it is probably slower than your
system's CPU. Therefore, we choose the 'sign-only' flavor when
building OpenSSL.
The Keyper-specific PKCS #11 provider library is delivered with the
Keyper software. In this example, we place it /opt/pkcs11/usr/lib:
cp pkcs11.GCC4.0.2.so.4.05 /opt/pkcs11/usr/lib/libpkcs11.so
This library is only available for Linux as a 32-bit binary. If we are
compiling on a 64-bit Linux system, it is necessary to force a 32-bit
build, by specifying -m32 in the build options.
Finally, the Keyper library requires threads, so we must specify -pthread.
cd openssl-0.9.8l
./Configure linux-generic32 -m32 -pthread \
--pk11-libname=/opt/pkcs11/usr/lib/libpkcs11.so \
--pk11-flavor=sign-only \
--prefix=/opt/pkcs11/usr
After configuring, run "make" and "make test". If "make test" fails
with "pthread_atfork() not found", you forgot to add the -pthread
above.
EXAMPLE 2--BUILDING OPENSSL FOR THE SCA 6000 ON SOLARIS:
The SCA-6000 PKCS #11 provider is installed as a system library,
libpkcs11. It is a true crypto accelerator, up to 4 times faster
than any CPU, so the flavor shall be 'crypto-accelerator'.
In this example, we are building on Solaris x86 on an AMD64 system.
cd openssl-0.9.8l
./Configure solaris64-x86_64-cc \
--pk11-libname=/usr/lib/64/libpkcs11.so \
--pk11-flavor=crypto-accelerator \
--prefix=/opt/pkcs11/usr
(For a 32-bit build, use "solaris-x86-cc" and /usr/lib/libpkcs11.so.)
After configuring, run "make" and "make test".
Once you have built OpenSSL, run "apps/openssl engine pkcs11" to confirm
that PKCS #11 support was compiled in correctly. The output should be
one of the following lines, depending on the flavor selected:
(pkcs11) PKCS #11 engine support (sign only)
Or:
(pkcs11) PKCS #11 engine support (crypto accelerator)
Next, run "apps/openssl engine pkcs11 -t". This will attempt to initialize
the PKCS #11 engine. If it is able to do so successfully, it will report
"[ available ]".
If the output is correct, run "make install".
BUILDING BIND 9
When building BIND 9, the location of the custom-built OpenSSL
library must be specified via configure.
EXAMPLE 3--CONFIGURING BIND 9 FOR LINUX
To link with the PKCS #11 provider, threads must be enabled in the
BIND 9 build.
The PKCS #11 library for the AEP Keyper is currently only available as
a 32-bit binary. If we are building on a 64-bit host, we must force a
32-bit build by adding "-m32" to the CC options on the "configure"
command line.
cd ../bind-9.7.0b1
./configure CC="gcc -m32" --enable-threads \
--with-openssl=/opt/pkcs11/usr \
--with-pkcs11=/opt/pkcs11/usr/lib/libpkcs11.so
EXAMPLE 4--CONFIGURING BIND 9 FOR SOLARIS
To link with the PKCS #11 provider, threads must be enabled in the
BIND 9 build.
cd ../bind-9.7.0b1
./configure CC="cc -xarch=amd64" --enable-threads \
--with-openssl=/opt/pkcs11/usr \
--with-pkcs11=/usr/lib/64/libpkcs11.so
(For a 32-bit build, omit CC="cc -xarch=amd64".)
If configure complains about OpenSSL not working, you may have a 32/64-bit
architecture mismatch. Or, you may have incorrectly specified the path to
OpenSSL (it should be the same as the --prefix argument to the OpenSSL
Configure).
After configuring, run "make", "make test" and "make install".
PKCS #11 TOOLS
BIND 9 includes a minimal set of tools to operate the HSM, including
"pkcs11-keygen" to generate a new key pair within the HSM, "pkcs11-list"
to list objects currently available, and "pkcs11-destroy" to remove
objects.
In UNIX/Linux builds, these tools are built only if BIND 9 is configured
with the --with-pkcs11 option. (NOTE: If --with-pkcs11 is set to "yes",
rather than to the path of the PKCS #11 provider, then the tools will be
built but the provider will be left undefined. Use the -m option or the
PKCS11_PROVIDER environment variable to specify the path to the provider.)
USING THE HSM
First, we must set up the runtime environment so the OpenSSL and PKCS #11
libraries can be loaded:
export LD_LIBRARY_PATH=/opt/pkcs11/usr/lib:${LD_LIBRARY_PATH}
When operating an AEP Keyper, it is also necessary to specify the
location of the "machine" file, which stores information about the Keyper
for use by PKCS #11 provider library. If the machine file is in
/opt/Keyper/PKCS11Provider/machine, use:
export KEYPER_LIBRARY_PATH=/opt/Keyper/PKCS11Provider
These environment variables must be set whenever running any tool
that uses the HSM, including pkcs11-keygen, pkcs11-list, pkcs11-destroy,
dnssec-keyfromlabel, dnssec-signzone, dnssec-keygen (which will use
the HSM for random number generation), and named.
We can now create and use keys in the HSM. In this case, we will
create a 2048 bit key and give it the label "sample-ksk":
pkcs11-keygen -b 2048 -l sample-ksk
To confirm that the key exists:
pkcs11-list
Enter PIN:
object[0]: handle 2147483658 class 3 label[8] 'sample-ksk' id[0]
object[1]: handle 2147483657 class 2 label[8] 'sample-ksk' id[0]
Before using this key to sign a zone, we must create a pair of BIND 9
key files. The "dnssec-keyfromlabel" utility does this. In this case,
we will be using the HSM key "sample-ksk" as the key-signing key for
"example.net":
dnssec-keyfromlabel -l sample-ksk -f KSK example.net
The resulting K*.key and K*.private files can now be used to sign the
zone. Unlike normal K* files, which contain both public and private
key data, these files will contain only the public key data, plus an
identifier for the private key which remains stored within the HSM.
The HSM handles signing with the private key.
If you wish to generate a second key in the HSM for use as a zone-signing
key, follow the same procedure above, using a different keylabel, a
smaller key size, and omitting "-f KSK" from the dnssec-keyfromlabel
arguments:
pkcs11-keygen -b 1024 -l sample-zsk
dnssec-keyfromlabel -l sample-zsk example.net
Alternatively, you may prefer to generate a conventional on-disk key,
using dnssec-keygen:
dnssec-keygen example.net
This provides less security than an HSM key, but since HSMs can be
slow or cumbersome to use for security reasons, it may be more
efficient to reserve HSM keys for use in the less frequent
key-signing operation. The zone-signing key can be rolled more
frequently, if you wish, to compensate for a reduction in key
security.
Now you can sign the zone. (Note: If not using the -S option to
dnssec-signzone, it will be necessary to add the contents of both
K*.key files to the zone master file before signing it.)
dnssec-signzone -S example.net
Enter PIN:
Verifying the zone using the following algorithms: NSEC3RSASHA1.
Zone signing complete:
Algorithm: NSEC3RSASHA1: ZSKs: 1, KSKs: 1 active, 0 revoked, 0 stand-by
example.net.signed
SPECIFYING THE ENGINE ON THE COMMAND LINE
The OpenSSL engine can be specified in named and all of the dnssec-*
tools by using the "-E <engine>" command line option. If BIND 9 is built
with the --with-pkcs11 option, this option defaults to "pkcs11".
Specifying the engine will generally not be necessary unless for
some reason you wish to use a different OpenSSL engine.
If you wish to disable use of the "pkcs11" engine--for troubleshooting
purposes, or because the HSM is unavailable--set the engine to the empty
string. For example:
dnssec-signzone -E '' -S example.net
This causes dnssec-signzone to run as if it were compiled without the
--with-pkcs11 option.
RUNNING NAMED WITH AUTOMATIC ZONE RE-SIGNING
If you want named to dynamically re-sign zones using HSM keys, and/or to
to sign new records inserted via nsupdate, then named must have access
to the HSM PIN. This can be accomplished by placing the PIN into the
openssl.cnf file (in the above examples, /opt/pkcs11/usr/ssl/openssl.cnf).
The location of the openssl.cnf file can be overridden by setting the
OPENSSL_CONF environment variable before running named.
Sample openssl.cnf:
openssl_conf = openssl_def
[ openssl_def ]
engines = engine_section
[ engine_section ]
pkcs11 = pkcs11_section
[ pkcs11_section ]
PIN = <PLACE PIN HERE>
This will also allow the dnssec-* tools to access the HSM without
PIN entry. (The pkcs11-* tools access the HSM directly, not via
OpenSSL, so a PIN will still be required to use them.)
PLEASE NOTE: Placing the HSM's PIN in a text file in this manner
may reduce the security advantage of using an HSM. Be sure this
is what you want to do before configuring BIND 9 in this way.

BIND 9 RFC 5011 support
BIND 9.7.0 introduces support for RFC 5011, dynamic trust anchor
management. Using this feature allows named to keep track of changes to
critical DNSSEC keys without any need for the operator to make changes to
configuration files.
VALIDATING RESOLVER
-------------------
To configure a validating resolver to use RFC5011 to maintain a trust
anchor, configure the trust anchor using a "managed-keys" statement.
Information about this can be found in the ARM, in the section titled
"managed-keys Statement Definition".
AUTHORITATIVE SERVER
--------------------
To set up an authoritative zone for RFC5011 trust anchor maintenance,
generate two (or more) key signing keys (KSKs) for the zone. Sign the zone
with one of them; this is the "active" KSK. All KSK's which do not sign
the zone are "stand-by" keys.
Any validating resolver which is configured to use the active KSK as an
RFC5011-managed trust anchor will take note of the stand-by KSKs in the
zone's DNSKEY RRset, and store them for future reference. The resolver
will recheck the zone periodically, and after 30 days, if the new key is
still there, then the key will be accepted by the resolver as a valid
trust anchor for the zone. Any time after this 30-day acceptance timer
has completed, the active KSK can be revoked, and the zone can be "rolled
over" to the newly accepted key.
The easiest way to place a stand-by key in a zone is to use the "smart
signing" features of dnssec-keygen and dnssec-signzone. If a key with a
publication date in the past, but an activation date which is unset or in
the future, "dnssec-signzone -S" will include the DNSKEY record in the
zone, but will not sign with it:
$ dnssec-keygen -K keys -f KSK -P now -A now+2y example.net
$ dnssec-signzone -S -K keys example.net
To revoke a key, the new command "dnssec-revoke" has been added. This adds
the REVOKED bit to the key flags and re-generates the K*.key and K*.private
files.
After revoking the active key, the zone must be signed with both the
revoked KSK and the new active KSK. (Smart signing takes care of this
automatically.)
Once a key has been revoked and used to sign the DNSKEY RRset in which it
appears, that key will never again be accepted as a valid trust anchor by
the resolver. However, validation can proceed using the new active key
(which had been accepted by the resolver when it was a stand-by key).
See RFC 5011 for more details on key rollover scenarios.
When a key has been revoked, its key ID changes, increasing by
128, and wrapping around at 65535. So, for example, the key
"Kexample.com.+005+10000" becomes "Kexample.com.+005+10128".
If two keys have ID's exactly 128 apart, and one is revoked, then the
two key ID's will collide, causing several problems. To prevent this,
dnssec-keygen will not generate a new key if another key is present which
may collide. This checking will only occur if the new keys are written
to the same directory which holds all other keys in use for that zone.
Older versions of BIND 9 did not have this precaution. Exercise caution if
using key revocation on keys that were generated by previous releases, or
if using keys stored in multiple directories or on multiple machines.
It is expected that a future release of BIND 9 will address this problem
in a different way, by storing revoked keys with their original unrevoked
key ID's.

.SH "NAME"
named\-checkconf \- named configuration file syntax checking tool
.SH "SYNOPSIS"
.HP 16
\fBnamed\-checkconf\fR [\fB\-h\fR] [\fB\-v\fR] [\fB\-j\fR] [\fB\-t\ \fR\fB\fIdirectory\fR\fR] {filename} [\fB\-p\fR] [\fB\-z\fR]
.SH "DESCRIPTION"
.PP
\fBnamed\-checkconf\fR
checks the syntax, but not the semantics, of a
\fBnamed\fR
configuration file. The file is parsed and checked for syntax errors, along with all files included by it. If no file is specified,
\fI/etc/named.conf\fR
is read by default.
.PP
Note: files that
\fBnamed\fR
reads in separate parser contexts, such as
\fIrndc.key\fR
and
\fIbind.keys\fR, are not automatically read by
\fBnamed\-checkconf\fR. Configuration errors in these files may cause
\fBnamed\fR
to fail to run, even if
\fBnamed\-checkconf\fR
was successful.
\fBnamed\-checkconf\fR
can be run on these files explicitly, however.
.SH "OPTIONS"
.PP
\-h
.RS 4
Print the usage summary and exit.
.RE
.PP
\-t \fIdirectory\fR
.RS 4
Chroot to
\fIdirectory\fR
so that include directives in the configuration file are processed as if run by a similarly chrooted named.
.RE
.PP
\-v
.RS 4
Print the version of the
\fBnamed\-checkconf\fR
program and exit.
.RE
.PP
\-p
.RS 4
Print out the
\fInamed.conf\fR
and included files in canonical form if no errors were detected.
.RE
.PP
\-z
.RS 4
Perform a test load of all master zones found in
\fInamed.conf\fR.
.RE
.PP
\-j
.RS 4
When loading a zonefile read the journal if it exists.
.RE
.PP
filename
.RS 4
The name of the configuration file to be checked. If not specified, it defaults to
\fI/etc/named.conf\fR.
.RE
.SH "RETURN VALUES"
.PP
\fBnamed\-checkconf\fR
returns an exit status of 1 if errors were detected and 0 otherwise.
.SH "SEE ALSO"

.SH "DESCRIPTION"
.PP
\fBnamed\-checkzone\fR
checks the syntax and integrity of a zone file. It performs the same checks as
\fBnamed\fR
does when loading a zone. This makes
\fBnamed\-checkzone\fR
useful for checking zone files before configuring them into a name server.
.PP
\fBnamed\-compilezone\fR
is similar to
\fBnamed\-checkzone\fR, but it always dumps the zone contents to a specified file in a specified format. Additionally, it applies stricter check levels by default, since the dump output will be used as an actual zone file loaded by
\fBnamed\fR. When manually specified otherwise, the check levels must at least be as strict as those specified in the
\fBnamed\fR
configuration file.
.SH "OPTIONS"
.PP
\-d
.RS 4
Enable debugging.
.RE
.PP
\-h
.RS 4
Print the usage summary and exit.
.RE
.PP
\-q
.RS 4
Quiet mode \- exit code only.
.RE
.PP
\-v
.RS 4
Print the version of the
\fBnamed\-checkzone\fR
program and exit.
.RE
.PP
\-j
.RS 4
When loading the zone file read the journal if it exists.
.RE
.PP
\-c \fIclass\fR
.RS 4
Specify the class of the zone. If not specified, "IN" is assumed.
.RE
.PP
\-i \fImode\fR
.RS 4
Perform post\-load zone integrity checks. Possible modes are
\fB"full"\fR
(default),
\fB"full\-sibling"\fR,
\fB"local"\fR,
\fB"local\-sibling"\fR
and
\fB"none"\fR.
.sp
Mode
\fB"full"\fR
checks that MX records refer to A or AAAA record (both in\-zone and out\-of\-zone hostnames). Mode
\fB"local"\fR
only checks MX records which refer to in\-zone hostnames.
.sp
Mode
\fB"full"\fR
checks that SRV records refer to A or AAAA record (both in\-zone and out\-of\-zone hostnames). Mode
\fB"local"\fR
only checks SRV records which refer to in\-zone hostnames.
.sp
Mode
\fB"full"\fR
checks that delegation NS records refer to A or AAAA record (both in\-zone and out\-of\-zone hostnames). It also checks that glue address records in the zone match those advertised by the child. Mode
\fB"local"\fR
only checks NS records which refer to in\-zone hostnames or that some required glue exists, that is when the nameserver is in a child zone.
.sp
Mode
\fB"full\-sibling"\fR
and
\fB"local\-sibling"\fR
disable sibling glue checks but are otherwise the same as
\fB"full"\fR
and
\fB"local"\fR
respectively.
.sp
Mode
\fB"none"\fR
disables the checks.
.RE
.PP
\-f \fIformat\fR
.RS 4
Specify the format of the zone file. Possible formats are
\fB"text"\fR
(default) and
\fB"raw"\fR.
.RE
.PP
\-F \fIformat\fR
.RS 4
Specify the format of the output file specified. Possible formats are
\fB"text"\fR
(default) and
\fB"raw"\fR. For
\fBnamed\-checkzone\fR, this does not cause any effects unless it dumps the zone contents.
.RE
.PP
\-k \fImode\fR
.RS 4
Perform
\fB"check\-names"\fR
checks with the specified failure mode. Possible modes are
\fB"fail"\fR
(default for
\fBnamed\-compilezone\fR),
\fB"warn"\fR
(default for
\fBnamed\-checkzone\fR) and
\fB"ignore"\fR.
.RE
.PP
\-m \fImode\fR
.RS 4
Specify whether MX records should be checked to see if they are addresses. Possible modes are
\fB"fail"\fR,
\fB"warn"\fR
(default) and
\fB"ignore"\fR.
.RE
.PP
\-M \fImode\fR
.RS 4
Check if a MX record refers to a CNAME. Possible modes are
\fB"fail"\fR,
\fB"warn"\fR
(default) and
\fB"ignore"\fR.
.RE
.PP
\-n \fImode\fR
.RS 4
Specify whether NS records should be checked to see if they are addresses. Possible modes are
\fB"fail"\fR
(default for
\fBnamed\-compilezone\fR),
\fB"warn"\fR
(default for
\fBnamed\-checkzone\fR) and
\fB"ignore"\fR.
.RE
.PP
\-o \fIfilename\fR
.RS 4
Write zone output to
\fIfilename\fR. If
\fIfilename\fR
is
\fI\-\fR
then write to standard out. This is mandatory for
\fBnamed\-compilezone\fR.
.RE
.PP
\-r \fImode\fR
.RS 4
Check for records that are treated as different by DNSSEC but are semantically equal in plain DNS. Possible modes are
\fB"fail"\fR,
\fB"warn"\fR
(default) and
\fB"ignore"\fR.
.RE
.PP
\-s \fIstyle\fR
.RS 4
Specify the style of the dumped zone file. Possible styles are
\fB"full"\fR
(default) and
\fB"relative"\fR. The full format is most suitable for processing automatically by a separate script. On the other hand, the relative format is more human\-readable and is thus suitable for editing by hand. For
\fBnamed\-checkzone\fR
this does not cause any effects unless it dumps the zone contents. It also does not have any meaning if the output format is not text.
.RE
.PP
\-S \fImode\fR
.RS 4
Check if a SRV record refers to a CNAME. Possible modes are
\fB"fail"\fR,
\fB"warn"\fR
(default) and
\fB"ignore"\fR.
.RE
.PP
\-t \fIdirectory\fR
.RS 4
Chroot to
\fIdirectory\fR
so that include directives in the configuration file are processed as if run by a similarly chrooted named.
.RE
.PP
\-w \fIdirectory\fR
.RS 4
chdir to
\fIdirectory\fR
so that relative filenames in master file $INCLUDE directives work. This is similar to the directory clause in
\fInamed.conf\fR.
.RE
.PP
\-D
.RS 4
Dump zone file in canonical format. This is always enabled for
\fBnamed\-compilezone\fR.
.RE
.PP
\-W \fImode\fR
.RS 4
Specify whether to check for non\-terminal wildcards. Non\-terminal wildcards are almost always the result of a failure to understand the wildcard matching algorithm (RFC 1034). Possible modes are
\fB"warn"\fR
(default) and
\fB"ignore"\fR.
.RE
.PP
zonename
.RS 4
The domain name of the zone being checked.
.RE
.PP
filename
.RS 4
The name of the zone file.
.RE
.SH "RETURN VALUES"
.PP
\fBnamed\-checkzone\fR
returns an exit status of 1 if errors were detected and 0 otherwise.
.SH "SEE ALSO"

<title>DESCRIPTION</title>
<para><command>named-checkzone</command>
checks the syntax and integrity of a zone file. It performs the
same checks as <command>named</command> does when loading a
zone. This makes <command>named-checkzone</command> useful for
checking zone files before configuring them into a name server.
</para>
<para>
<command>named-compilezone</command> is similar to
<command>named-checkzone</command>, but it always dumps the
zone contents to a specified file in a specified format.
Additionally, it applies stricter check levels by default,
since the dump output will be used as an actual zone file
loaded by <command>named</command>.
When manually specified otherwise, the check levels must at
least be as strict as those specified in the
<command>named</command> configuration file.

<a name="id2543691"></a><h2>DESCRIPTION</h2>
<p><span><strong class="command">named-checkzone</strong></span>
checks the syntax and integrity of a zone file. It performs the
same checks as <span><strong class="command">named</strong></span> does when loading a
zone. This makes <span><strong class="command">named-checkzone</strong></span> useful for
checking zone files before configuring them into a name server.
</p>
<p>
<span><strong class="command">named-compilezone</strong></span> is similar to
<span><strong class="command">named-checkzone</strong></span>, but it always dumps the
zone contents to a specified file in a specified format.
Additionally, it applies stricter check levels by default,
since the dump output will be used as an actual zone file
loaded by <span><strong class="command">named</strong></span>.
When manually specified otherwise, the check levels must at
least be as strict as those specified in the
<span><strong class="command">named</strong></span> configuration file.

.SH "DESCRIPTION"
.PP
\fBddns\-confgen\fR
generates a key for use by
\fBnsupdate\fR
and
\fBnamed\fR. It simplifies configuration of dynamic zones by generating a key and providing the
\fBnsupdate\fR
and
\fBnamed.conf\fR
syntax that will be needed to use it, including an example
\fBupdate\-policy\fR
statement.
.PP
If a domain name is specified on the command line, it will be used in the name of the generated key and in the sample
\fBnamed.conf\fR
syntax. For example,
\fBddns\-confgen example.com\fR
would generate a key called "ddns\-key.example.com", and sample
\fBnamed.conf\fR
command that could be used in the zone definition for "example.com".
.PP
Note that
\fBnamed\fR
itself can configure a local DDNS key for use with
\fBnsupdate \-l\fR.
\fBddns\-confgen\fR
is only needed when a more elaborate configuration is required: for instance, if
\fBnsupdate\fR
is to be used from a remote system.
.SH "OPTIONS"
.PP
\-a \fIalgorithm\fR
.RS 4
Specifies the algorithm to use for the TSIG key. Available choices are: hmac\-md5, hmac\-sha1, hmac\-sha224, hmac\-sha256, hmac\-sha384 and hmac\-sha512. The default is hmac\-sha256.
.RE
.PP
\-h
.RS 4
Prints a short summary of the options and arguments to
\fBddns\-confgen\fR.
.RE
.PP
\-k \fIkeyname\fR
.RS 4
Specifies the key name of the DDNS authentication key. The default is
\fBddns\-key\fR
when neither the
\fB\-s\fR
nor
\fB\-z\fR
option is specified; otherwise, the default is
\fBddns\-key\fR
as a separate label followed by the argument of the option, e.g.,
\fBddns\-key.example.com.\fR
The key name must have the format of a valid domain name, consisting of letters, digits, hyphens and periods.
.RE
.PP
\-q
.RS 4
Quiet mode: Print only the key, with no explanatory text or usage examples.
.RE
.PP
\-r \fIrandomfile\fR
.RS 4
Specifies a source of random data for generating the authorization. If the operating system does not provide a
\fI/dev/random\fR
or equivalent device, the default source of randomness is keyboard input.
\fIrandomdev\fR
specifies the name of a character device or file containing random data to be used instead of the default. The special value
\fIkeyboard\fR
indicates that keyboard input should be used.
.RE
.PP
\-s \fIname\fR
.RS 4
Single host mode: The example
\fBnamed.conf\fR
text shows how to set an update policy for the specified
\fIname\fR
using the "name" nametype. The default key name is ddns\-key.\fIname\fR. Note that the "self" nametype cannot be used, since the name to be updated may differ from the key name. This option cannot be used with the
\fB\-z\fR
option.
.RE
.PP
\-z \fIzone\fR
.RS 4
zone mode: The example
\fBnamed.conf\fR
text shows how to set an update policy for the specified
\fIzone\fR
using the "zonesub" nametype, allowing updates to all subdomain names within that
\fIzone\fR. This option cannot be used with the
\fB\-s\fR
option.

rndc\-confgen \- rndc key generation tool
.SH "SYNOPSIS"
.HP 13
\fBrndc\-confgen\fR [\fB\-a\fR] [\fB\-b\ \fR\fB\fIkeysize\fR\fR] [\fB\-c\ \fR\fB\fIkeyfile\fR\fR] [\fB\-h\fR] [\fB\-k\ \fR\fB\fIkeyname\fR\fR] [\fB\-p\ \fR\fB\fIport\fR\fR] [\fB\-r\ \fR\fB\fIrandomfile\fR\fR] [\fB\-s\ \fR\fB\fIaddress\fR\fR] [\fB\-t\ \fR\fB\fIchrootdir\fR\fR] [\fB\-u\ \fR\fB\fIuser\fR\fR]
.SH "DESCRIPTION"
.PP
\fBrndc\-confgen\fR
generates configuration files for
\fBrndc\fR. It can be used as a convenient alternative to writing the
\fIrndc.conf\fR
file and the corresponding
\fBcontrols\fR
and
\fBkey\fR
statements in
\fInamed.conf\fR
by hand. Alternatively, it can be run with the
\fB\-a\fR
option to set up a
\fIrndc.key\fR
file and avoid the need for a
\fIrndc.conf\fR
file and a
\fBcontrols\fR
statement altogether.
.SH "OPTIONS"
.PP
\-a
.RS 4
Do automatic
\fBrndc\fR
configuration. This creates a file
\fIrndc.key\fR
in
\fI/etc\fR
(or whatever
\fIsysconfdir\fR
was specified as when
BIND
was built) that is read by both
\fBrndc\fR
and
\fBnamed\fR
on startup. The
\fIrndc.key\fR
file defines a default command channel and authentication key allowing
\fBrndc\fR
to communicate with
\fBnamed\fR
on the local host with no further configuration.
.sp
Running
\fBrndc\-confgen \-a\fR
allows BIND 9 and
\fBrndc\fR
to be used as drop\-in replacements for BIND 8 and
\fBndc\fR, with no changes to the existing BIND 8
\fInamed.conf\fR
file.
.sp
If a more elaborate configuration than that generated by
\fBrndc\-confgen \-a\fR
is required, for example if rndc is to be used remotely, you should run
\fBrndc\-confgen\fR
without the
\fB\-a\fR
option and set up a
\fIrndc.conf\fR
and
\fInamed.conf\fR
as directed.
.RE
.PP
\-b \fIkeysize\fR
.RS 4
Specifies the size of the authentication key in bits. Must be between 1 and 512 bits; the default is 128.
.RE
.PP
\-c \fIkeyfile\fR
.RS 4
Used with the
\fB\-a\fR
option to specify an alternate location for
\fIrndc.key\fR.
.RE
.PP
\-h
.RS 4
Prints a short summary of the options and arguments to
\fBrndc\-confgen\fR.
.RE
.PP
\-k \fIkeyname\fR
.RS 4
Specifies the key name of the rndc authentication key. This must be a valid domain name. The default is
\fBrndc\-key\fR.
.RE
.PP
\-p \fIport\fR
.RS 4
Specifies the command channel port where
\fBnamed\fR
listens for connections from
\fBrndc\fR. The default is 953.
.RE
.PP
\-r \fIrandomfile\fR
.RS 4
Specifies a source of random data for generating the authorization. If the operating system does not provide a
\fI/dev/random\fR
or equivalent device, the default source of randomness is keyboard input.
\fIrandomdev\fR
specifies the name of a character device or file containing random data to be used instead of the default. The special value
\fIkeyboard\fR
indicates that keyboard input should be used.
.RE
.PP
\-s \fIaddress\fR
.RS 4
Specifies the IP address where
\fBnamed\fR
listens for command channel connections from
\fBrndc\fR. The default is the loopback address 127.0.0.1.
.RE
.PP
\-t \fIchrootdir\fR
.RS 4
Used with the
\fB\-a\fR
option to specify a directory where
\fBnamed\fR
will run chrooted. An additional copy of the
\fIrndc.key\fR
will be written relative to this directory so that it will be found by the chrooted
\fBnamed\fR.
.RE
.PP
\-u \fIuser\fR
.RS 4
Used with the
\fB\-a\fR
option to set the owner of the
\fIrndc.key\fR
file generated. If
\fB\-t\fR
is also specified only the file in the chroot area has its owner changed.
.RE
.SH "EXAMPLES"
.PP
To allow
\fBrndc\fR
to be used with no manual configuration, run
.PP
\fBrndc\-confgen \-a\fR
.PP
To print a sample
\fIrndc.conf\fR
file and corresponding
\fBcontrols\fR
and
\fBkey\fR
statements to be manually inserted into
\fInamed.conf\fR, run
.PP
\fBrndc\-confgen\fR

<title>DESCRIPTION</title>
<para><command>rndc-confgen</command>
generates configuration files
for <command>rndc</command>. It can be used as a
convenient alternative to writing the
<filename>rndc.conf</filename> file
and the corresponding <command>controls</command>
and <command>key</command>
statements in <filename>named.conf</filename> by hand.
Alternatively, it can be run with the <command>-a</command>
option to set up a <filename>rndc.key</filename> file and
avoid the need for a <filename>rndc.conf</filename> file
and a <command>controls</command> statement altogether.
</para>
</refsect1>

<title>OPTIONS</title>
<variablelist>
<varlistentry>
<term>-a</term>
<listitem>
<para>
Do automatic <command>rndc</command> configuration.
This creates a file <filename>rndc.key</filename>
in <filename>/etc</filename> (or whatever
<varname>sysconfdir</varname>
was specified as when <acronym>BIND</acronym> was
built)
that is read by both <command>rndc</command>
and <command>named</command> on startup. The
<filename>rndc.key</filename> file defines a default
command channel and authentication key allowing
<command>rndc</command> to communicate with
<command>named</command> on the local host
with no further configuration.
</para>
<para>
Running <command>rndc-confgen -a</command> allows
BIND 9 and <command>rndc</command> to be used as
drop-in
replacements for BIND 8 and <command>ndc</command>,
with no changes to the existing BIND 8
<filename>named.conf</filename> file.
</para>
<para>
If a more elaborate configuration than that
generated by <command>rndc-confgen -a</command>
is required, for example if rndc is to be used remotely,
you should run <command>rndc-confgen</command> without
the
<command>-a</command> option and set up a
<filename>rndc.conf</filename> and
<filename>named.conf</filename>
as directed.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-b <replaceable class="parameter">keysize</replaceable></term>

<varlistentry>
<term>-p <replaceable class="parameter">port</replaceable></term>

The default is 953.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-r <replaceable class="parameter">randomfile</replaceable></term>
<listitem>
<para>
Specifies a source of random data for generating the
authorization. If the operating
system does not provide a <filename>/dev/random</filename>
or equivalent device, the default source of randomness
is keyboard input. <filename>randomdev</filename>
specifies
the name of a character device or file containing random
data to be used instead of the default. The special value
<filename>keyboard</filename> indicates that keyboard
input should be used.
</para>
</listitem>
</varlistentry>

<term>-s <replaceable class="parameter">address</replaceable></term>
<listitem>
<para>
Specifies the IP address where <command>named</command>

</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-t <replaceable class="parameter">chrootdir</replaceable></term>
<listitem>
<para>
Used with the <command>-a</command> option to specify
a directory where <command>named</command> will run
chrooted. An additional copy of the <filename>rndc.key</filename>
will be written relative to this directory so that
it will be found by the chrooted <command>named</command>.

\fBdig\fR
(domain information groper) is a flexible tool for interrogating DNS name servers. It performs DNS lookups and displays the answers that are returned from the name server(s) that were queried. Most DNS administrators use
\fBdig\fR
to troubleshoot DNS problems because of its flexibility, ease of use and clarity of output. Other lookup tools tend to have less functionality than
\fBdig\fR.
.PP
Although
\fBdig\fR
is normally used with command\-line arguments, it also has a batch mode of operation for reading lookup requests from a file. A brief summary of its command\-line arguments and options is printed when the
\fB\-h\fR
option is given. Unlike earlier versions, the BIND 9 implementation of
\fBdig\fR
allows multiple lookups to be issued from the command line.
.PP
Unless it is told to query a specific name server,
\fBdig\fR
will try each of the servers listed in
\fI/etc/resolv.conf\fR.
.PP
When no command line arguments or options are given,
\fBdig\fR
will perform an NS query for "." (the root).
.PP
It is possible to set per\-user defaults for
\fBdig\fR
via
\fI${HOME}/.digrc\fR. This file is read and any options in it are applied before the command line arguments.
.PP
The IN and CH class names overlap with the IN and CH top level domains names. Either use the
\fB\-t\fR
and
\fB\-c\fR
options to specify the type and class, use the
\fB\-q\fR
the specify the domain name, or use "IN." and "CH." when looking up these top level domains.
.SH "SIMPLE USAGE"
.PP
A typical invocation of
\fBdig\fR
looks like:
.sp
.RS 4
.nf
dig @server name type
.fi
.RE
.sp
where:
.PP
\fBserver\fR
.RS 4
is the name or IP address of the name server to query. This can be an IPv4 address in dotted\-decimal notation or an IPv6 address in colon\-delimited notation. When the supplied
\fIserver\fR
argument is a hostname,
\fBdig\fR
resolves that name before querying that name server. If no
\fIserver\fR
argument is provided,
\fBdig\fR
consults
\fI/etc/resolv.conf\fR
and queries the name servers listed there. The reply from the name server that responds is displayed.
.RE
.PP
\fBname\fR
.RS 4
is the name of the resource record that is to be looked up.
.RE
.PP
\fBtype\fR
.RS 4
indicates what type of query is required \(em ANY, A, MX, SIG, etc.
\fItype\fR
can be any valid query type. If no
\fItype\fR
argument is supplied,
\fBdig\fR
will perform a lookup for an A record.
.RE
.SH "OPTIONS"
.PP
The
\fB\-b\fR
option sets the source IP address of the query to
\fIaddress\fR. This must be a valid address on one of the host's network interfaces or "0.0.0.0" or "::". An optional port may be specified by appending "#<port>"
.PP
The default query class (IN for internet) is overridden by the
\fB\-c\fR
option.
\fIclass\fR
is any valid class, such as HS for Hesiod records or CH for Chaosnet records.
.PP
The
\fB\-f\fR
option makes
\fBdig \fR
operate in batch mode by reading a list of lookup requests to process from the file
\fIfilename\fR. The file contains a number of queries, one per line. Each entry in the file should be organized in the same way they would be presented as queries to
\fBdig\fR
using the command\-line interface.
.PP
The
\fB\-m\fR
option enables memory usage debugging.
.PP
If a non\-standard port number is to be queried, the
\fB\-p\fR
option is used.
\fIport#\fR
is the port number that
\fBdig\fR
will send its queries instead of the standard DNS port number 53. This option would be used to test a name server that has been configured to listen for queries on a non\-standard port number.
.PP
The
\fB\-4\fR
option forces
\fBdig\fR
to only use IPv4 query transport. The
\fB\-6\fR
option forces
\fBdig\fR
to only use IPv6 query transport.
.PP
The
\fB\-t\fR
option sets the query type to
\fItype\fR. It can be any valid query type which is supported in BIND 9. The default query type is "A", unless the
\fB\-x\fR
option is supplied to indicate a reverse lookup. A zone transfer can be requested by specifying a type of AXFR. When an incremental zone transfer (IXFR) is required,
\fItype\fR
is set to
ixfr=N. The incremental zone transfer will contain the changes made to the zone since the serial number in the zone's SOA record was
\fIN\fR.
.PP
The
\fB\-q\fR
option sets the query name to
\fIname\fR. This useful do distinguish the
\fIname\fR
from other arguments.
.PP
Reverse lookups \(em mapping addresses to names \(em are simplified by the
\fB\-x\fR
option.
\fIaddr\fR
is an IPv4 address in dotted\-decimal notation, or a colon\-delimited IPv6 address. When this option is used, there is no need to provide the
\fIname\fR,
\fIclass\fR
and
\fItype\fR
arguments.
\fBdig\fR
automatically performs a lookup for a name like
11.12.13.10.in\-addr.arpa
and sets the query type and class to PTR and IN respectively. By default, IPv6 addresses are looked up using nibble format under the IP6.ARPA domain. To use the older RFC1886 method using the IP6.INT domain specify the
\fB\-i\fR
option. Bit string labels (RFC2874) are now experimental and are not attempted.
.PP
To sign the DNS queries sent by
\fBdig\fR
and their responses using transaction signatures (TSIG), specify a TSIG key file using the
\fB\-k\fR
option. You can also specify the TSIG key itself on the command line using the
\fB\-y\fR
option;
\fIhmac\fR
is the type of the TSIG, default HMAC\-MD5,
\fIname\fR
is the name of the TSIG key and
\fIkey\fR
is the actual key. The key is a base\-64 encoded string, typically generated by
\fBdnssec\-keygen\fR(8). Caution should be taken when using the
\fB\-y\fR
option on multi\-user systems as the key can be visible in the output from
\fBps\fR(1)
or in the shell's history file. When using TSIG authentication with
\fBdig\fR, the name server that is queried needs to know the key and algorithm that is being used. In BIND, this is done by providing appropriate
\fBkey\fR
and
\fBserver\fR
statements in
\fInamed.conf\fR.
.SH "QUERY OPTIONS"
.PP
\fBdig\fR
provides a number of query options which affect the way in which lookups are made and the results displayed. Some of these set or reset flag bits in the query header, some determine which sections of the answer get printed, and others determine the timeout and retry strategies.
.PP
Each query option is identified by a keyword preceded by a plus sign (+). Some keywords set or reset an option. These may be preceded by the string
no
to negate the meaning of that keyword. Other keywords assign values to options like the timeout interval. They have the form
\fB+keyword=value\fR. The query options are:
.PP
\fB+[no]tcp\fR
.RS 4
Use [do not use] TCP when querying name servers. The default behavior is to use UDP unless an AXFR or IXFR query is requested, in which case a TCP connection is used.
.RE
.PP
\fB+[no]vc\fR
.RS 4
Use [do not use] TCP when querying name servers. This alternate syntax to
\fI+[no]tcp\fR
is provided for backwards compatibility. The "vc" stands for "virtual circuit".
.RE
.PP
\fB+[no]ignore\fR
.RS 4
Ignore truncation in UDP responses instead of retrying with TCP. By default, TCP retries are performed.
.RE
.PP
\fB+domain=somename\fR
.RS 4
Set the search list to contain the single domain
\fIsomename\fR, as if specified in a
\fBdomain\fR
directive in
\fI/etc/resolv.conf\fR, and enable search list processing as if the
\fI+search\fR
option were given.
.RE
.PP
\fB+[no]search\fR
.RS 4
Use [do not use] the search list defined by the searchlist or domain directive in
\fIresolv.conf\fR
(if any). The search list is not used by default.
.RE
.PP
\fB+[no]showsearch\fR
.RS 4

.RE
.PP
\fB+[no]aaflag\fR
.RS 4
A synonym for
\fI+[no]aaonly\fR.
.RE
.PP
\fB+[no]adflag\fR
.RS 4
Set [do not set] the AD (authentic data) bit in the query. This requests the server to return whether all of the answer and authority sections have all been validated as secure according to the security policy of the server. AD=1 indicates that all records have been validated as secure and the answer is not from a OPT\-OUT range. AD=0 indicate that some part of the answer was insecure or not validated.
.RE
.PP
\fB+[no]cdflag\fR
.RS 4
Set [do not set] the CD (checking disabled) bit in the query. This requests the server to not perform DNSSEC validation of responses.
.RE
.PP
\fB+[no]cl\fR
.RS 4
Display [do not display] the CLASS when printing the record.
.RE
.PP
\fB+[no]ttlid\fR
.RS 4
Display [do not display] the TTL when printing the record.
.RE
.PP
\fB+[no]recurse\fR
.RS 4
Toggle the setting of the RD (recursion desired) bit in the query. This bit is set by default, which means
\fBdig\fR
normally sends recursive queries. Recursion is automatically disabled when the
\fI+nssearch\fR
or
\fI+trace\fR
query options are used.
.RE
.PP
\fB+[no]nssearch\fR
.RS 4
When this option is set,
\fBdig\fR
attempts to find the authoritative name servers for the zone containing the name being looked up and display the SOA record that each name server has for the zone.
.RE
.PP
\fB+[no]trace\fR
.RS 4
Toggle tracing of the delegation path from the root name servers for the name being looked up. Tracing is disabled by default. When tracing is enabled,
\fBdig\fR
makes iterative queries to resolve the name being looked up. It will follow referrals from the root servers, showing the answer from each server that was used to resolve the lookup.
.RE
.PP
\fB+[no]cmd\fR
.RS 4
Toggles the printing of the initial comment in the output identifying the version of
\fBdig\fR
and the query options that have been applied. This comment is printed by default.
.RE
.PP
\fB+[no]short\fR
.RS 4
Provide a terse answer. The default is to print the answer in a verbose form.
.RE
.PP
\fB+[no]identify\fR
.RS 4
Show [or do not show] the IP address and port number that supplied the answer when the
\fI+short\fR
option is enabled. If short form answers are requested, the default is not to show the source address and port number of the server that provided the answer.
.RE
.PP
\fB+[no]comments\fR
.RS 4
Toggle the display of comment lines in the output. The default is to print comments.
.RE
.PP
\fB+[no]stats\fR
.RS 4
This query option toggles the printing of statistics: when the query was made, the size of the reply and so on. The default behavior is to print the query statistics.
.RE
.PP
\fB+[no]qr\fR
.RS 4
Print [do not print] the query as it is sent. By default, the query is not printed.
.RE
.PP
\fB+[no]question\fR
.RS 4
Print [do not print] the question section of a query when an answer is returned. The default is to print the question section as a comment.
.RE
.PP
\fB+[no]answer\fR
.RS 4
Display [do not display] the answer section of a reply. The default is to display it.
.RE
.PP
\fB+[no]authority\fR
.RS 4
Display [do not display] the authority section of a reply. The default is to display it.
.RE
.PP
\fB+[no]additional\fR
.RS 4
Display [do not display] the additional section of a reply. The default is to display it.
.RE
.PP
\fB+[no]all\fR
.RS 4
Set or clear all display flags.
.RE
.PP
\fB+time=T\fR
.RS 4
Sets the timeout for a query to
\fIT\fR
seconds. The default timeout is 5 seconds. An attempt to set
\fIT\fR
to less than 1 will result in a query timeout of 1 second being applied.
.RE
.PP
\fB+tries=T\fR
.RS 4
Sets the number of times to try UDP queries to server to
\fIT\fR
instead of the default, 3. If
\fIT\fR
is less than or equal to zero, the number of tries is silently rounded up to 1.
.RE
.PP
\fB+retry=T\fR
.RS 4
Sets the number of times to retry UDP queries to server to
\fIT\fR
instead of the default, 2. Unlike
\fI+tries\fR, this does not include the initial query.
.RE
.PP
\fB+ndots=D\fR
.RS 4
Set the number of dots that have to appear in
\fIname\fR
to
\fID\fR
for it to be considered absolute. The default value is that defined using the ndots statement in
\fI/etc/resolv.conf\fR, or 1 if no ndots statement is present. Names with fewer dots are interpreted as relative names and will be searched for in the domains listed in the
\fBsearch\fR
or
\fBdomain\fR
directive in
\fI/etc/resolv.conf\fR.
.RE
.PP
\fB+bufsize=B\fR
.RS 4
Set the UDP message buffer size advertised using EDNS0 to
\fIB\fR
bytes. The maximum and minimum sizes of this buffer are 65535 and 0 respectively. Values outside this range are rounded up or down appropriately. Values other than zero will cause a EDNS query to be sent.
.RE
.PP
\fB+edns=#\fR
.RS 4
Specify the EDNS version to query with. Valid values are 0 to 255. Setting the EDNS version will cause a EDNS query to be sent.
\fB+noedns\fR
clears the remembered EDNS version.
.RE
.PP
\fB+[no]multiline\fR
.RS 4
Print records like the SOA records in a verbose multi\-line format with human\-readable comments. The default is to print each record on a single line, to facilitate machine parsing of the
\fBdig\fR
output.
.RE
.PP
\fB+[no]fail\fR
.RS 4
Do not try the next server if you receive a SERVFAIL. The default is to not try the next server which is the reverse of normal stub resolver behavior.
.RE
.PP
\fB+[no]besteffort\fR
.RS 4
Attempt to display the contents of messages which are malformed. The default is to not display malformed answers.
.RE
.PP
\fB+[no]dnssec\fR
.RS 4
Requests DNSSEC records be sent by setting the DNSSEC OK bit (DO) in the OPT record in the additional section of the query.
.RE
.PP
\fB+[no]sigchase\fR
.RS 4
Chase DNSSEC signature chains. Requires dig be compiled with \-DDIG_SIGCHASE.
.RE
.PP
\fB+trusted\-key=####\fR
.RS 4
Specifies a file containing trusted keys to be used with
\fB+sigchase\fR. Each DNSKEY record must be on its own line.
.sp
If not specified,
\fBdig\fR
will look for
\fI/etc/trusted\-key.key\fR
then
\fItrusted\-key.key\fR
in the current directory.
.sp
Requires dig be compiled with \-DDIG_SIGCHASE.
.RE
.PP

.RE
.PP
\fB+[no]nsid\fR
.RS 4
Include an EDNS name server ID request when sending a query.
.RE
.SH "MULTIPLE QUERIES"
.PP
The BIND 9 implementation of
\fBdig \fR
supports specifying multiple queries on the command line (in addition to supporting the
\fB\-f\fR
batch file option). Each of those queries can be supplied with its own set of flags, options and query options.
.PP
In this case, each
\fIquery\fR
argument represent an individual query in the command\-line syntax described above. Each consists of any of the standard options and flags, the name to be looked up, an optional query type and class and any query options that should be applied to that query.
.PP
A global set of query options, which should be applied to all queries, can also be supplied. These global query options must precede the first tuple of name, class, type, options, flags, and query options supplied on the command line. Any global query options (except the
\fB+[no]cmd\fR
option) can be overridden by a query\-specific set of query options. For example:
.sp
.RS 4
.nf
dig +qr www.isc.org any \-x 127.0.0.1 isc.org ns +noqr
.fi
.RE
.sp
shows how
\fBdig\fR
could be used from the command line to make three lookups: an ANY query for
www.isc.org, a reverse lookup of 127.0.0.1 and a query for the NS records of
isc.org. A global query option of
\fI+qr\fR
is applied, so that
\fBdig\fR
shows the initial query it made for each lookup. The final query has a local query option of
\fI+noqr\fR
which means that
\fBdig\fR
will not print the initial query when it looks up the NS records for
isc.org.
.SH "IDN SUPPORT"
.PP
If
\fBdig\fR
has been built with IDN (internationalized domain name) support, it can accept and display non\-ASCII domain names.
\fBdig\fR
appropriately converts character encoding of domain name before sending a request to DNS server or displaying a reply from the server. If you'd like to turn off the IDN support for some reason, defines the
\fBIDN_DISABLE\fR
environment variable. The IDN support is disabled if the variable is set when
\fBdig\fR
runs.
.SH "FILES"

</variablelist>
</para>
</refsect1>
<refsect1>
<title>OPTIONS</title>
<para>
The <option>-b</option> option sets the source IP address of the query
to <parameter>address</parameter>. This must be a valid
address on
one of the host's network interfaces or "0.0.0.0" or "::". An optional
port
may be specified by appending "#&lt;port&gt;"
</para>
<para>
The default query class (IN for internet) is overridden by the
<option>-c</option> option. <parameter>class</parameter> is
any valid
class, such as HS for Hesiod records or CH for Chaosnet records.
</para>
<para>
The <option>-f</option> option makes <command>dig </command>
operate
in batch mode by reading a list of lookup requests to process from the
file <parameter>filename</parameter>. The file contains a
number of
queries, one per line. Each entry in the file should be organized in
the same way they would be presented as queries to
<command>dig</command> using the command-line interface.
</para>
<para>
The <option>-m</option> option enables memory usage debugging.
<!-- It enables ISC_MEM_DEBUGTRACE and ISC_MEM_DEBUGRECORD
documented in include/isc/mem.h -->
</para>
<para>
If a non-standard port number is to be queried, the
<option>-p</option> option is used. <parameter>port#</parameter> is
the port number that <command>dig</command> will send its
queries
instead of the standard DNS port number 53. This option would be used
to test a name server that has been configured to listen for queries
on a non-standard port number.
</para>
<para>
The <option>-4</option> option forces <command>dig</command>
to only
use IPv4 query transport. The <option>-6</option> option forces
<command>dig</command> to only use IPv6 query transport.
</para>
<para>
The <option>-t</option> option sets the query type to
<parameter>type</parameter>. It can be any valid query type
which is
supported in BIND 9. The default query type is "A", unless the
<option>-x</option> option is supplied to indicate a reverse lookup.
A zone transfer can be requested by specifying a type of AXFR. When
an incremental zone transfer (IXFR) is required,
<parameter>type</parameter> is set to <literal>ixfr=N</literal>.
The incremental zone transfer will contain the changes made to the zone
since the serial number in the zone's SOA record was
<parameter>N</parameter>.
</para>
<para>
The <option>-q</option> option sets the query name to
<parameter>name</parameter>. This useful do distinguish the
<parameter>name</parameter> from other arguments.
</para>
<para>
Reverse lookups &mdash; mapping addresses to names &mdash; are simplified by the
<option>-x</option> option. <parameter>addr</parameter> is
an IPv4
address in dotted-decimal notation, or a colon-delimited IPv6 address.
When this option is used, there is no need to provide the
<parameter>name</parameter>, <parameter>class</parameter> and
<parameter>type</parameter> arguments. <command>dig</command>
automatically performs a lookup for a name like
<literal>11.12.13.10.in-addr.arpa</literal> and sets the
query type and
class to PTR and IN respectively. By default, IPv6 addresses are
looked up using nibble format under the IP6.ARPA domain.
To use the older RFC1886 method using the IP6.INT domain
specify the <option>-i</option> option. Bit string labels (RFC2874)
are now experimental and are not attempted.
</para>
<para>
To sign the DNS queries sent by <command>dig</command> and
their
responses using transaction signatures (TSIG), specify a TSIG key file
using the <option>-k</option> option. You can also specify the TSIG
key itself on the command line using the <option>-y</option> option;
<parameter>hmac</parameter> is the type of the TSIG, default HMAC-MD5,
<parameter>name</parameter> is the name of the TSIG key and
<parameter>key</parameter> is the actual key. The key is a
base-64
encoded string, typically generated by
<citerefentry>
<refentrytitle>dnssec-keygen</refentrytitle><manvolnum>8</manvolnum>
</citerefentry>.
Caution should be taken when using the <option>-y</option> option on
multi-user systems as the key can be visible in the output from
<citerefentry>
<refentrytitle>ps</refentrytitle><manvolnum>1</manvolnum>
</citerefentry>
or in the shell's history file. When
using TSIG authentication with <command>dig</command>, the name
server that is queried needs to know the key and algorithm that is
being used. In BIND, this is done by providing appropriate
<command>key</command> and <command>server</command> statements in
<filename>named.conf</filename>.
</para>
</refsect1>
<refsect1>
<title>QUERY OPTIONS</title>
<para><command>dig</command>
provides a number of query options which affect
the way in which lookups are made and the results displayed. Some of
these set or reset flag bits in the query header, some determine which
sections of the answer get printed, and others determine the timeout
and retry strategies.
</para>
<para>
Each query option is identified by a keyword preceded by a plus sign
(<literal>+</literal>). Some keywords set or reset an
option. These may be preceded
by the string <literal>no</literal> to negate the meaning of
that keyword. Other
keywords assign values to options like the timeout interval. They
have the form <option>+keyword=value</option>.
The query options are:
<variablelist>
<varlistentry>
<term><option>+[no]tcp</option></term>
<listitem>
<para>
Use [do not use] TCP when querying name servers. The default
behavior is to use UDP unless an AXFR or IXFR query is

<title>MULTIPLE QUERIES</title>
<para>
The BIND 9 implementation of <command>dig </command>
supports
specifying multiple queries on the command line (in addition to
supporting the <option>-f</option> batch file option). Each of those
queries can be supplied with its own set of flags, options and query
options.
</para>
<para>
In this case, each <parameter>query</parameter> argument
represent an
individual query in the command-line syntax described above. Each
consists of any of the standard options and flags, the name to be
looked up, an optional query type and class and any query options that
should be applied to that query.
</para>
<para>
A global set of query options, which should be applied to all queries,
can also be supplied. These global query options must precede the
first tuple of name, class, type, options, flags, and query options
supplied on the command line. Any global query options (except
the <option>+[no]cmd</option> option) can be
overridden by a query-specific set of query options. For example:
<programlisting>
dig +qr www.isc.org any -x 127.0.0.1 isc.org ns +noqr
</programlisting>
shows how <command>dig</command> could be used from the
command line
to make three lookups: an ANY query for <literal>www.isc.org</literal>, a
reverse lookup of 127.0.0.1 and a query for the NS records of
<literal>isc.org</literal>.
A global query option of <parameter>+qr</parameter> is
applied, so
that <command>dig</command> shows the initial query it made
for each
lookup. The final query has a local query option of
<parameter>+noqr</parameter> which means that <command>dig</command>
will not print the initial query when it looks up the NS records for
<literal>isc.org</literal>.
</para>
</refsect1>
<refsect1>
<title>IDN SUPPORT</title>
<para>
If <command>dig</command> has been built with IDN (internationalized
domain name) support, it can accept and display non-ASCII domain names.
<command>dig</command> appropriately converts character encoding of
domain name before sending a request to DNS server or displaying a
reply from the server.
If you'd like to turn off the IDN support for some reason, defines
the <envar>IDN_DISABLE</envar> environment variable.
The IDN support is disabled if the variable is set when
<command>dig</command> runs.

<a name="id2543518"></a><h2>DESCRIPTION</h2>
<p><span><strong class="command">dig</strong></span>
(domain information groper) is a flexible tool
for interrogating DNS name servers. It performs DNS lookups and
displays the answers that are returned from the name server(s) that
were queried. Most DNS administrators use <span><strong class="command">dig</strong></span> to
troubleshoot DNS problems because of its flexibility, ease of use and
clarity of output. Other lookup tools tend to have less functionality
than <span><strong class="command">dig</strong></span>.
</p>
<p>
Although <span><strong class="command">dig</strong></span> is normally used with
command-line
arguments, it also has a batch mode of operation for reading lookup
requests from a file. A brief summary of its command-line arguments
and options is printed when the <code class="option">-h</code> option is given.
Unlike earlier versions, the BIND 9 implementation of
<span><strong class="command">dig</strong></span> allows multiple lookups to be issued
from the
command line.
</p>
<p>
Unless it is told to query a specific name server,
<span><strong class="command">dig</strong></span> will try each of the servers listed
in
<code class="filename">/etc/resolv.conf</code>.
</p>
<p>
When no command line arguments or options are given,
<span><strong class="command">dig</strong></span> will perform an NS query for "." (the root).
</p>
<p>
It is possible to set per-user defaults for <span><strong class="command">dig</strong></span> via
<code class="filename">${HOME}/.digrc</code>. This file is read and
any options in it
are applied before the command line arguments.
</p>
<p>
The IN and CH class names overlap with the IN and CH top level
domains names. Either use the <code class="option">-t</code> and
<code class="option">-c</code> options to specify the type and class,
use the <code class="option">-q</code> the specify the domain name, or
use "IN." and "CH." when looking up these top level domains.
</p>
</div>
<div class="refsect1" lang="en">
<a name="id2543592"></a><h2>SIMPLE USAGE</h2>
<p>
A typical invocation of <span><strong class="command">dig</strong></span> looks like:
</p>
<pre class="programlisting"> dig @server name type </pre>
<p>
where:
</p>
<div class="variablelist"><dl>
<dt><span class="term"><code class="constant">server</code></span></dt>
<dd><p>
is the name or IP address of the name server to query. This can
be an IPv4
address in dotted-decimal notation or an IPv6
address in colon-delimited notation. When the supplied
<em class="parameter"><code>server</code></em> argument is a
hostname,
<span><strong class="command">dig</strong></span> resolves that name before
querying that name
server. If no <em class="parameter"><code>server</code></em>
argument is provided,
<span><strong class="command">dig</strong></span> consults <code class="filename">/etc/resolv.conf</code>
and queries the name servers listed there. The reply from the
name
server that responds is displayed.
</p></dd>
<dt><span class="term"><code class="constant">name</code></span></dt>
<dd><p>
is the name of the resource record that is to be looked up.
</p></dd>
<dt><span class="term"><code class="constant">type</code></span></dt>
<dd><p>
indicates what type of query is required &#8212;
ANY, A, MX, SIG, etc.
<em class="parameter"><code>type</code></em> can be any valid query
type. If no
<em class="parameter"><code>type</code></em> argument is supplied,
<span><strong class="command">dig</strong></span> will perform a lookup for an
A record.
</p></dd>
</dl></div>
<p>
</p>
</div>
<div class="refsect1" lang="en">
<a name="id2543683"></a><h2>OPTIONS</h2>
<p>
The <code class="option">-b</code> option sets the source IP address of the query
to <em class="parameter"><code>address</code></em>. This must be a valid
address on
one of the host's network interfaces or "0.0.0.0" or "::". An optional
port
may be specified by appending "#&lt;port&gt;"
</p>
<p>
The default query class (IN for internet) is overridden by the
<code class="option">-c</code> option. <em class="parameter"><code>class</code></em> is
any valid
class, such as HS for Hesiod records or CH for Chaosnet records.
</p>
<p>
The <code class="option">-f</code> option makes <span><strong class="command">dig </strong></span>
operate
in batch mode by reading a list of lookup requests to process from the
file <em class="parameter"><code>filename</code></em>. The file contains a
number of
queries, one per line. Each entry in the file should be organized in
the same way they would be presented as queries to
<span><strong class="command">dig</strong></span> using the command-line interface.
</p>
<p>
The <code class="option">-m</code> option enables memory usage debugging.
</p>
<p>
If a non-standard port number is to be queried, the
<code class="option">-p</code> option is used. <em class="parameter"><code>port#</code></em> is
the port number that <span><strong class="command">dig</strong></span> will send its
queries
instead of the standard DNS port number 53. This option would be used
to test a name server that has been configured to listen for queries
on a non-standard port number.
</p>
<p>
The <code class="option">-4</code> option forces <span><strong class="command">dig</strong></span>
to only
use IPv4 query transport. The <code class="option">-6</code> option forces
<span><strong class="command">dig</strong></span> to only use IPv6 query transport.
</p>
<p>
The <code class="option">-t</code> option sets the query type to
<em class="parameter"><code>type</code></em>. It can be any valid query type
which is
supported in BIND 9. The default query type is "A", unless the
<code class="option">-x</code> option is supplied to indicate a reverse lookup.
A zone transfer can be requested by specifying a type of AXFR. When
an incremental zone transfer (IXFR) is required,
<em class="parameter"><code>type</code></em> is set to <code class="literal">ixfr=N</code>.
The incremental zone transfer will contain the changes made to the zone
since the serial number in the zone's SOA record was
<em class="parameter"><code>N</code></em>.
</p>
<p>
The <code class="option">-q</code> option sets the query name to
<em class="parameter"><code>name</code></em>. This useful do distinguish the
<em class="parameter"><code>name</code></em> from other arguments.
</p>
<p>
Reverse lookups &#8212; mapping addresses to names &#8212; are simplified by the
<code class="option">-x</code> option. <em class="parameter"><code>addr</code></em> is
an IPv4
address in dotted-decimal notation, or a colon-delimited IPv6 address.
When this option is used, there is no need to provide the
<em class="parameter"><code>name</code></em>, <em class="parameter"><code>class</code></em> and
<em class="parameter"><code>type</code></em> arguments. <span><strong class="command">dig</strong></span>
automatically performs a lookup for a name like
<code class="literal">11.12.13.10.in-addr.arpa</code> and sets the
query type and
class to PTR and IN respectively. By default, IPv6 addresses are
looked up using nibble format under the IP6.ARPA domain.
To use the older RFC1886 method using the IP6.INT domain
specify the <code class="option">-i</code> option. Bit string labels (RFC2874)
are now experimental and are not attempted.
</p>
<p>
To sign the DNS queries sent by <span><strong class="command">dig</strong></span> and
their
responses using transaction signatures (TSIG), specify a TSIG key file
using the <code class="option">-k</code> option. You can also specify the TSIG
key itself on the command line using the <code class="option">-y</code> option;
<em class="parameter"><code>hmac</code></em> is the type of the TSIG, default HMAC-MD5,
<em class="parameter"><code>name</code></em> is the name of the TSIG key and
<em class="parameter"><code>key</code></em> is the actual key. The key is a
base-64
encoded string, typically generated by
<span class="citerefentry"><span class="refentrytitle">dnssec-keygen</span>(8)</span>.
Caution should be taken when using the <code class="option">-y</code> option on
multi-user systems as the key can be visible in the output from
<span class="citerefentry"><span class="refentrytitle">ps</span>(1)</span>
or in the shell's history file. When
using TSIG authentication with <span><strong class="command">dig</strong></span>, the name
server that is queried needs to know the key and algorithm that is
being used. In BIND, this is done by providing appropriate
<span><strong class="command">key</strong></span> and <span><strong class="command">server</strong></span> statements in
<code class="filename">named.conf</code>.
</p>
</div>
<div class="refsect1" lang="en">
<a name="id2544032"></a><h2>QUERY OPTIONS</h2>
<p><span><strong class="command">dig</strong></span>
provides a number of query options which affect
the way in which lookups are made and the results displayed. Some of
these set or reset flag bits in the query header, some determine which
sections of the answer get printed, and others determine the timeout
and retry strategies.
</p>
<p>
Each query option is identified by a keyword preceded by a plus sign
(<code class="literal">+</code>). Some keywords set or reset an
option. These may be preceded
by the string <code class="literal">no</code> to negate the meaning of
that keyword. Other
keywords assign values to options like the timeout interval. They
have the form <code class="option">+keyword=value</code>.
The query options are:
</p>
<div class="variablelist"><dl>
<dt><span class="term"><code class="option">+[no]tcp</code></span></dt>
<dd><p>
Use [do not use] TCP when querying name servers. The default

requested, in
which case a TCP connection is used.
</p></dd>
<dt><span class="term"><code class="option">+[no]vc</code></span></dt>
<dd><p>
Use [do not use] TCP when querying name servers. This alternate
syntax to <em class="parameter"><code>+[no]tcp</code></em> is
provided for backwards
compatibility. The "vc" stands for "virtual circuit".
</p></dd>
<dt><span class="term"><code class="option">+[no]ignore</code></span></dt>

<dd><p>
Set [do not set] the AD (authentic data) bit in the
query. This requests the server to return whether
all of the answer and authority sections have all
been validated as secure according to the security
policy of the server. AD=1 indicates that all records
have been validated as secure and the answer is not
from a OPT-OUT range. AD=0 indicate that some part

<dt><span class="term"><code class="option">+[no]recurse</code></span></dt>
<dd><p>
Toggle the setting of the RD (recursion desired) bit in the
query.
This bit is set by default, which means <span><strong class="command">dig</strong></span>
normally sends recursive queries. Recursion is automatically
disabled
when the <em class="parameter"><code>+nssearch</code></em> or

</p></dd>
<dt><span class="term"><code class="option">+[no]trace</code></span></dt>
<dd><p>
Toggle tracing of the delegation path from the root name servers
for
the name being looked up. Tracing is disabled by default. When
tracing is enabled, <span><strong class="command">dig</strong></span> makes
iterative queries to
resolve the name being looked up. It will follow referrals from
the

<a name="id2545166"></a><h2>MULTIPLE QUERIES</h2>
<p>
The BIND 9 implementation of <span><strong class="command">dig </strong></span>
supports
specifying multiple queries on the command line (in addition to
supporting the <code class="option">-f</code> batch file option). Each of those
queries can be supplied with its own set of flags, options and query
options.
</p>
<p>
In this case, each <em class="parameter"><code>query</code></em> argument
represent an
individual query in the command-line syntax described above. Each
consists of any of the standard options and flags, the name to be
looked up, an optional query type and class and any query options that
should be applied to that query.
</p>
<p>
A global set of query options, which should be applied to all queries,
can also be supplied. These global query options must precede the
first tuple of name, class, type, options, flags, and query options
supplied on the command line. Any global query options (except
the <code class="option">+[no]cmd</code> option) can be
overridden by a query-specific set of query options. For example:
</p>
<pre class="programlisting">
dig +qr www.isc.org any -x 127.0.0.1 isc.org ns +noqr
</pre>
<p>
shows how <span><strong class="command">dig</strong></span> could be used from the
command line
to make three lookups: an ANY query for <code class="literal">www.isc.org</code>, a
reverse lookup of 127.0.0.1 and a query for the NS records of
<code class="literal">isc.org</code>.
A global query option of <em class="parameter"><code>+qr</code></em> is
applied, so
that <span><strong class="command">dig</strong></span> shows the initial query it made
for each
lookup. The final query has a local query option of
<em class="parameter"><code>+noqr</code></em> which means that <span><strong class="command">dig</strong></span>
will not print the initial query when it looks up the NS records for
<code class="literal">isc.org</code>.
</p>
</div>
<div class="refsect1" lang="en">
<a name="id2545228"></a><h2>IDN SUPPORT</h2>
<p>
If <span><strong class="command">dig</strong></span> has been built with IDN (internationalized
domain name) support, it can accept and display non-ASCII domain names.
<span><strong class="command">dig</strong></span> appropriately converts character encoding of
domain name before sending a request to DNS server or displaying a
reply from the server.
If you'd like to turn off the IDN support for some reason, defines
the <code class="envar">IDN_DISABLE</code> environment variable.
The IDN support is disabled if the variable is set when
<span><strong class="command">dig</strong></span> runs.

.SH "SYNOPSIS"
.HP 5
\fBhost\fR [\fB\-aCdlnrsTwv\fR] [\fB\-c\ \fR\fB\fIclass\fR\fR] [\fB\-N\ \fR\fB\fIndots\fR\fR] [\fB\-R\ \fR\fB\fInumber\fR\fR] [\fB\-t\ \fR\fB\fItype\fR\fR] [\fB\-W\ \fR\fB\fIwait\fR\fR] [\fB\-m\ \fR\fB\fIflag\fR\fR] [\fB\-4\fR] [\fB\-6\fR] {name} [server]
.SH "DESCRIPTION"
.PP
\fBhost\fR
is a simple utility for performing DNS lookups. It is normally used to convert names to IP addresses and vice versa. When no arguments or options are given,
\fBhost\fR
prints a short summary of its command line arguments and options.
.PP
\fIname\fR
is the domain name that is to be looked up. It can also be a dotted\-decimal IPv4 address or a colon\-delimited IPv6 address, in which case
\fBhost\fR
will by default perform a reverse lookup for that address.
\fIserver\fR
is an optional argument which is either the name or IP address of the name server that
\fBhost\fR
should query instead of the server or servers listed in
\fI/etc/resolv.conf\fR.
.PP
The
\fB\-a\fR
(all) option is equivalent to setting the
\fB\-v\fR
option and asking
\fBhost\fR
to make a query of type ANY.
.PP
When the
\fB\-C\fR
option is used,
\fBhost\fR
will attempt to display the SOA records for zone
\fIname\fR
from all the listed authoritative name servers for that zone. The list of name servers is defined by the NS records that are found for the zone.
.PP
The
\fB\-c\fR
option instructs to make a DNS query of class
\fIclass\fR. This can be used to lookup Hesiod or Chaosnet class resource records. The default class is IN (Internet).
.PP
Verbose output is generated by
\fBhost\fR
when the
\fB\-d\fR
or
\fB\-v\fR
option is used. The two options are equivalent. They have been provided for backwards compatibility. In previous versions, the
\fB\-d\fR
option switched on debugging traces and
\fB\-v\fR
enabled verbose output.
.PP
List mode is selected by the
\fB\-l\fR
option. This makes
\fBhost\fR
perform a zone transfer for zone
\fIname\fR. Transfer the zone printing out the NS, PTR and address records (A/AAAA). If combined with
\fB\-a\fR
all records will be printed.
.PP
The
\fB\-i\fR
option specifies that reverse lookups of IPv6 addresses should use the IP6.INT domain as defined in RFC1886. The default is to use IP6.ARPA.
.PP
The
\fB\-N\fR
option sets the number of dots that have to be in
\fIname\fR
for it to be considered absolute. The default value is that defined using the ndots statement in
\fI/etc/resolv.conf\fR, or 1 if no ndots statement is present. Names with fewer dots are interpreted as relative names and will be searched for in the domains listed in the
\fBsearch\fR
or
\fBdomain\fR
directive in
\fI/etc/resolv.conf\fR.
.PP
The number of UDP retries for a lookup can be changed with the
\fB\-R\fR
option.
\fInumber\fR
indicates how many times
\fBhost\fR
will repeat a query that does not get answered. The default number of retries is 1. If
\fInumber\fR
is negative or zero, the number of retries will default to 1.
.PP
Non\-recursive queries can be made via the
\fB\-r\fR
option. Setting this option clears the
\fBRD\fR
\(em recursion desired \(em bit in the query which
\fBhost\fR
makes. This should mean that the name server receiving the query will not attempt to resolve
\fIname\fR. The
\fB\-r\fR
option enables
\fBhost\fR
to mimic the behavior of a name server by making non\-recursive queries and expecting to receive answers to those queries that are usually referrals to other name servers.
.PP
By default,
\fBhost\fR
uses UDP when making queries. The
\fB\-T\fR
option makes it use a TCP connection when querying the name server. TCP will be automatically selected for queries that require it, such as zone transfer (AXFR) requests.
.PP
The
\fB\-4\fR
option forces
\fBhost\fR
to only use IPv4 query transport. The
\fB\-6\fR
option forces
\fBhost\fR
to only use IPv6 query transport.
.PP
The
\fB\-t\fR
option is used to select the query type.
\fItype\fR
can be any recognized query type: CNAME, NS, SOA, SIG, KEY, AXFR, etc. When no query type is specified,
\fBhost\fR
automatically selects an appropriate query type. By default, it looks for A, AAAA, and MX records, but if the
\fB\-C\fR
option was given, queries will be made for SOA records, and if
\fIname\fR
is a dotted\-decimal IPv4 address or colon\-delimited IPv6 address,
\fBhost\fR
will query for PTR records. If a query type of IXFR is chosen the starting serial number can be specified by appending an equal followed by the starting serial number (e.g. \-t IXFR=12345678).
.PP
The time to wait for a reply can be controlled through the
\fB\-W\fR
and
\fB\-w\fR
options. The
\fB\-W\fR
option makes
\fBhost\fR
wait for
\fIwait\fR
seconds. If
\fIwait\fR
is less than one, the wait interval is set to one second. When the
\fB\-w\fR
option is used,
\fBhost\fR
will effectively wait forever for a reply. The time to wait for a response will be set to the number of seconds given by the hardware's maximum value for an integer quantity.
.PP
The
\fB\-s\fR
option tells
\fBhost\fR
\fInot\fR
to send the query to the next nameserver if any server responds with a SERVFAIL response, which is the reverse of normal stub resolver behavior.
.PP
The
\fB\-m\fR
can be used to set the memory usage debugging flags
\fIrecord\fR,
\fIusage\fR
and
\fItrace\fR.
.SH "IDN SUPPORT"
.PP
If
\fBhost\fR
has been built with IDN (internationalized domain name) support, it can accept and display non\-ASCII domain names.
\fBhost\fR
appropriately converts character encoding of domain name before sending a request to DNS server or displaying a reply from the server. If you'd like to turn off the IDN support for some reason, defines the
\fBIDN_DISABLE\fR
environment variable. The IDN support is disabled if the variable is set when
\fBhost\fR
runs.

<title>DESCRIPTION</title>
<para><command>host</command>
is a simple utility for performing DNS lookups.
It is normally used to convert names to IP addresses and vice versa.
When no arguments or options are given,
<command>host</command>
prints a short summary of its command line arguments and options.
</para>
<para><parameter>name</parameter> is the domain name that is to be
looked
up. It can also be a dotted-decimal IPv4 address or a colon-delimited
IPv6 address, in which case <command>host</command> will by
default
perform a reverse lookup for that address.
<parameter>server</parameter> is an optional argument which
is either
the name or IP address of the name server that <command>host</command>
should query instead of the server or servers listed in
<filename>/etc/resolv.conf</filename>.
</para>
<para>
The <option>-a</option> (all) option is equivalent to setting the
<option>-v</option> option and asking <command>host</command> to make
a query of type ANY.
</para>
<para>
When the <option>-C</option> option is used, <command>host</command>
will attempt to display the SOA records for zone
<parameter>name</parameter> from all the listed
authoritative name
servers for that zone. The list of name servers is defined by the NS
records that are found for the zone.
</para>
<para>
The <option>-c</option> option instructs to make a DNS query of class
<parameter>class</parameter>. This can be used to lookup
Hesiod or
Chaosnet class resource records. The default class is IN (Internet).
</para>
<para>
Verbose output is generated by <command>host</command> when
the
<option>-d</option> or <option>-v</option> option is used. The two
options are equivalent. They have been provided for backwards
compatibility. In previous versions, the <option>-d</option> option
switched on debugging traces and <option>-v</option> enabled verbose
output.
</para>
<para>
List mode is selected by the <option>-l</option> option. This makes
<command>host</command> perform a zone transfer for zone
<parameter>name</parameter>. Transfer the zone printing out
the NS, PTR
and address records (A/AAAA). If combined with <option>-a</option>
all records will be printed.
</para>
<para>
The <option>-i</option>
option specifies that reverse lookups of IPv6 addresses should
use the IP6.INT domain as defined in RFC1886.
The default is to use IP6.ARPA.
</para>
<para>
The <option>-N</option> option sets the number of dots that have to be
in <parameter>name</parameter> for it to be considered
absolute. The
default value is that defined using the ndots statement in
<filename>/etc/resolv.conf</filename>, or 1 if no ndots
statement is
present. Names with fewer dots are interpreted as relative names and
will be searched for in the domains listed in the <type>search</type>
or <type>domain</type> directive in
<filename>/etc/resolv.conf</filename>.
</para>
<para>
The number of UDP retries for a lookup can be changed with the
<option>-R</option> option. <parameter>number</parameter>
indicates
how many times <command>host</command> will repeat a query
that does
not get answered. The default number of retries is 1. If
<parameter>number</parameter> is negative or zero, the
number of
retries will default to 1.
</para>
<para>
Non-recursive queries can be made via the <option>-r</option> option.
Setting this option clears the <type>RD</type> &mdash; recursion
desired &mdash; bit in the query which <command>host</command> makes.
This should mean that the name server receiving the query will not
attempt to resolve <parameter>name</parameter>. The
<option>-r</option> option enables <command>host</command>
to mimic
the behavior of a name server by making non-recursive queries and
expecting to receive answers to those queries that are usually
referrals to other name servers.
</para>
<para>
By default, <command>host</command> uses UDP when making
queries. The
<option>-T</option> option makes it use a TCP connection when querying
the name server. TCP will be automatically selected for queries that
require it, such as zone transfer (AXFR) requests.
</para>
<para>
The <option>-4</option> option forces <command>host</command> to only
use IPv4 query transport. The <option>-6</option> option forces
<command>host</command> to only use IPv6 query transport.
</para>
<para>
The <option>-t</option> option is used to select the query type.
<parameter>type</parameter> can be any recognized query
type: CNAME,
NS, SOA, SIG, KEY, AXFR, etc. When no query type is specified,
<command>host</command> automatically selects an appropriate
query
type. By default, it looks for A, AAAA, and MX records, but if the
<option>-C</option> option was given, queries will be made for SOA
records, and if <parameter>name</parameter> is a
dotted-decimal IPv4
address or colon-delimited IPv6 address, <command>host</command> will
query for PTR records. If a query type of IXFR is chosen the starting
serial number can be specified by appending an equal followed by the
starting serial number (e.g. -t IXFR=12345678).
</para>
<para>
The time to wait for a reply can be controlled through the
<option>-W</option> and <option>-w</option> options. The
<option>-W</option> option makes <command>host</command>
wait for
<parameter>wait</parameter> seconds. If <parameter>wait</parameter>
is less than one, the wait interval is set to one second. When the
<option>-w</option> option is used, <command>host</command>
will
effectively wait forever for a reply. The time to wait for a response
will be set to the number of seconds given by the hardware's maximum
value for an integer quantity.
</para>
<para>
The <option>-s</option> option tells <command>host</command>
<emphasis>not</emphasis> to send the query to the next nameserver
if any server responds with a SERVFAIL response, which is the
reverse of normal stub resolver behavior.
</para>
<para>
The <option>-m</option> can be used to set the memory usage debugging
flags
<parameter>record</parameter>, <parameter>usage</parameter> and
<parameter>trace</parameter>.
</para>
</refsect1>
<refsect1>
<title>IDN SUPPORT</title>
<para>
If <command>host</command> has been built with IDN (internationalized
domain name) support, it can accept and display non-ASCII domain names.
<command>host</command> appropriately converts character encoding of
domain name before sending a request to DNS server or displaying a
reply from the server.
If you'd like to turn off the IDN support for some reason, defines
the <envar>IDN_DISABLE</envar> environment variable.
The IDN support is disabled if the variable is set when
<command>host</command> runs.

.SH "NAME"
nslookup \- query Internet name servers interactively
.SH "SYNOPSIS"
.HP 9
\fBnslookup\fR [\fB\-option\fR] [name\ |\ \-] [server]
.SH "DESCRIPTION"
.PP
\fBNslookup\fR
is a program to query Internet domain name servers.
\fBNslookup\fR
has two modes: interactive and non\-interactive. Interactive mode allows the user to query name servers for information about various hosts and domains or to print a list of hosts in a domain. Non\-interactive mode is used to print just the name and requested information for a host or domain.
.SH "ARGUMENTS"
.PP
Interactive mode is entered in the following cases:
.TP 4
1.
when no arguments are given (the default name server will be used)
.TP 4
2.
when the first argument is a hyphen (\-) and the second argument is the host name or Internet address of a name server.
.sp
.RE
.PP
Non\-interactive mode is used when the name or Internet address of the host to be looked up is given as the first argument. The optional second argument specifies the host name or address of a name server.
.PP
Options can also be specified on the command line if they precede the arguments and are prefixed with a hyphen. For example, to change the default query type to host information, and the initial timeout to 10 seconds, type:
.sp .RS 4 .nf nslookup \-query=hinfo \-timeout=10 .fi .RE
.SH "INTERACTIVE COMMANDS"
.PP
\fBhost\fR [server]
.RS 4
Look up information for host using the current default server or using server, if specified. If host is an Internet address and the query type is A or PTR, the name of the host is returned. If host is a name and does not have a trailing period, the search list is used to qualify the name.
.sp
To look up a host not in the current domain, append a period to the name.
.RE
.PP
\fBserver\fR \fIdomain\fR
.RS 4
.RE
.PP
\fBlserver\fR \fIdomain\fR
.RS 4
Change the default server to
\fIdomain\fR;
\fBlserver\fR
uses the initial server to look up information about
\fIdomain\fR, while
\fBserver\fR
uses the current default server. If an authoritative answer can't be found, the names of servers that might have the answer are returned.

<title>DESCRIPTION</title>
<para><command>Nslookup</command>
is a program to query Internet domain name servers. <command>Nslookup</command>
has two modes: interactive and non-interactive. Interactive mode allows
the user to query name servers for information about various hosts and
domains or to print a list of hosts in a domain. Non-interactive mode
is
used to print just the name and requested information for a host or
domain.
</para>
</refsect1>
<refsect1>
<title>ARGUMENTS</title>
<para>
Interactive mode is entered in the following cases:
<orderedlist numeration="loweralpha">
<listitem>
<para>
when no arguments are given (the default name server will be used)
</para>
</listitem>
<listitem>
<para>
when the first argument is a hyphen (-) and the second argument is
the host name or Internet address of a name server.
</para>
</listitem>
</orderedlist>
</para>
<para>
Non-interactive mode is used when the name or Internet address of the
host to be looked up is given as the first argument. The optional second
argument specifies the host name or address of a name server.
</para>
<para>
Options can also be specified on the command line if they precede the
arguments and are prefixed with a hyphen. For example, to
change the default query type to host information, and the initial
timeout to 10 seconds, type:
<informalexample>
<programlisting>
nslookup -query=hinfo -timeout=10
</programlisting>
</informalexample>
</para>

<p><span><strong class="command">Nslookup</strong></span>
is a program to query Internet domain name servers. <span><strong class="command">Nslookup</strong></span>
has two modes: interactive and non-interactive. Interactive mode allows
the user to query name servers for information about various hosts and
domains or to print a list of hosts in a domain. Non-interactive mode
is
used to print just the name and requested information for a host or
domain.
</p>
</div>
<div class="refsect1" lang="en">
<a name="id2543371"></a><h2>ARGUMENTS</h2>
<p>
Interactive mode is entered in the following cases:
</p>
<div class="orderedlist"><ol type="a">
<li><p>
when no arguments are given (the default name server will be used)
</p></li>
<li><p>
when the first argument is a hyphen (-) and the second argument is
the host name or Internet address of a name server.
</p></li>
</ol></div>
<p>
</p>
<p>
Non-interactive mode is used when the name or Internet address of the
host to be looked up is given as the first argument. The optional second
argument specifies the host name or address of a name server.
</p>
<p>
Options can also be specified on the command line if they precede the
arguments and are prefixed with a hyphen. For example, to
change the default query type to host information, and the initial
timeout to 10 seconds, type:
</p>
<div class="informalexample"><pre class="programlisting">
nslookup -query=hinfo -timeout=10

.SH "DESCRIPTION"
.PP
\fBdnssec\-dsfromkey\fR
outputs the Delegation Signer (DS) resource record (RR), as defined in RFC 3658 and RFC 4509, for the given key(s).
.SH "OPTIONS"
.PP
\-1
.RS 4
Use SHA\-1 as the digest algorithm (the default is to use both SHA\-1 and SHA\-256).
.RE
.PP
\-2
.RS 4
Use SHA\-256 as the digest algorithm.
.RE
.PP
\-a \fIalgorithm\fR
.RS 4
Select the digest algorithm. The value of
\fBalgorithm\fR
must be one of SHA\-1 (SHA1) or SHA\-256 (SHA256). These values are case insensitive.
.RE
.PP
\-K \fIdirectory\fR
.RS 4
Look for key files (or, in keyset mode,
\fIkeyset\-\fR
files) in
\fBdirectory\fR.
.RE
.PP
\-f \fIfile\fR
.RS 4
Zone file mode: in place of the keyfile name, the argument is the DNS domain name of a zone master file, which can be read from
\fBfile\fR. If the zone name is the same as
\fBfile\fR, then it may be omitted.
.RE
.PP
\-A
.RS 4
Include ZSK's when generating DS records. Without this option, only keys which have the KSK flag set will be converted to DS records and printed. Useful only in zone file mode.
.RE
.PP
\-l \fIdomain\fR
.RS 4
Generate a DLV set instead of a DS set. The specified
\fBdomain\fR
is appended to the name for each record in the set. The DNSSEC Lookaside Validation (DLV) RR is described in RFC 4431.
.RE
.PP
\-s
.RS 4
Keyset mode: in place of the keyfile name, the argument is the DNS domain name of a keyset file.
.RE
.PP
\-c \fIclass\fR
.RS 4
Specifies the DNS class (default is IN). Useful only in keyset or zone file mode.
.RE
.PP
\-v \fIlevel\fR
.RS 4
Sets the debugging level.
.RE
.SH "EXAMPLE"
.PP
To build the SHA\-256 DS RR from the
\fBKexample.com.+003+26160\fR
keyfile name, the following command would be issued:
.PP
\fBdnssec\-dsfromkey \-2 Kexample.com.+003+26160\fR
.PP
The command would print something like:
.PP
\fBexample.com. IN DS 26160 5 2 3A1EADA7A74B8D0BA86726B0C227AA85AB8BBD2B2004F41A868A54F0 C5EA0B94\fR
.SH "FILES"
.PP
The keyfile can be designed by the key identification
\fIKnnnn.+aaa+iiiii\fR
or the full file name
\fIKnnnn.+aaa+iiiii.key\fR
as generated by
dnssec\-keygen(8).
.PP
The keyset file name is built from the
\fBdirectory\fR, the string
\fIkeyset\-\fR
and the
\fBdnsname\fR.
.SH "CAVEAT"
.PP
A keyfile error can give a "file not found" even if the file exists.
.SH "SEE ALSO"
.PP

<title>EXAMPLE</title>
<para>
To build the SHA-256 DS RR from the
<userinput>Kexample.com.+003+26160</userinput>
keyfile name, the following command would be issued:
</para>
<para><userinput>dnssec-dsfromkey -2 Kexample.com.+003+26160</userinput>
</para>
<para>
The command would print something like:
</para>
<para><userinput>example.com. IN DS 26160 5 2 3A1EADA7A74B8D0BA86726B0C227AA85AB8BBD2B2004F41A868A54F0 C5EA0B94</userinput>
</para>
</refsect1>
<refsect1>
<title>FILES</title>
<para>
The keyfile can be designed by the key identification
<filename>Knnnn.+aaa+iiiii</filename> or the full file name
<filename>Knnnn.+aaa+iiiii.key</filename> as generated by
<refentrytitle>dnssec-keygen</refentrytitle><manvolnum>8</manvolnum>.
</para>
<para>
The keyset file name is built from the <option>directory</option>,
the string <filename>keyset-</filename> and the
<option>dnsname</option>.
</para>

\fBname\fR
of the key is specified on the command line. This must match the name of the zone for which the key is being generated.
.SH "OPTIONS"
.PP
\-a \fIalgorithm\fR
.RS 4
Selects the cryptographic algorithm. The value of
\fBalgorithm\fR
must be one of RSAMD5, RSASHA1, DSA, NSEC3RSASHA1, NSEC3DSA, RSASHA256 or RSASHA512. These values are case insensitive.
.sp
If no algorithm is specified, then RSASHA1 will be used by default, unless the
\fB\-3\fR
option is specified, in which case NSEC3RSASHA1 will be used instead. (If
\fB\-3\fR
is used and an algorithm is specified, that algorithm will be checked for compatibility with NSEC3.)
.sp
Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement algorithm, and DSA is recommended.
.sp
Note 2: DH automatically sets the \-k flag.
.RE
.PP
\-3
.RS 4
Use an NSEC3\-capable algorithm to generate a DNSSEC key. If this option is used and no algorithm is explicitly set on the command line, NSEC3RSASHA1 will be used by default.
.RE
.PP
\-E \fIengine\fR
.RS 4
Specifies the name of the crypto hardware (OpenSSL engine). When compiled with PKCS#11 support it defaults to "pkcs11".
.RE
.PP
\-l \fIlabel\fR
.RS 4
Specifies the label of the key pair in the crypto hardware. The label may be preceded by an optional OpenSSL engine name, separated by a colon, as in "pkcs11:keylabel".
.RE
.PP
\-n \fInametype\fR
.RS 4
Specifies the owner type of the key. The value of
\fBnametype\fR
must either be ZONE (for a DNSSEC zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with a host (KEY)), USER (for a key associated with a user(KEY)) or OTHER (DNSKEY). These values are case insensitive.
.RE
.PP
\-C
.RS 4
Compatibility mode: generates an old\-style key, without any metadata. By default,
\fBdnssec\-keyfromlabel\fR
will include the key's creation date in the metadata stored with the private key, and other dates may be set there as well (publication date, activation date, etc). Keys that include this data may be incompatible with older versions of BIND; the
\fB\-C\fR
option suppresses them.
.RE
.PP
\-c \fIclass\fR
.RS 4
Indicates that the DNS record containing the key should have the specified class. If not specified, class IN is used.
.RE
.PP
\-f \fIflag\fR
.RS 4
Set the specified flag in the flag field of the KEY/DNSKEY record. The only recognized flags are KSK (Key Signing Key) and REVOKE.
.RE
.PP
\-G
.RS 4
Generate a key, but do not publish it or sign with it. This option is incompatible with \-P and \-A.
.RE
.PP
\-h
.RS 4
Prints a short summary of the options and arguments to
\fBdnssec\-keyfromlabel\fR.
.RE
.PP
\-K \fIdirectory\fR
.RS 4
Sets the directory in which the key files are to be written.
.RE
.PP
\-k
.RS 4
Generate KEY records rather than DNSKEY records.
.RE
.PP
\-p \fIprotocol\fR
.RS 4
Sets the protocol value for the key. The protocol is a number between 0 and 255. The default is 3 (DNSSEC). Other possible values for this argument are listed in RFC 2535 and its successors.
.RE
.PP
\-t \fItype\fR
.RS 4
Indicates the use of the key.
\fBtype\fR
must be one of AUTHCONF, NOAUTHCONF, NOAUTH, or NOCONF. The default is AUTHCONF. AUTH refers to the ability to authenticate data, and CONF the ability to encrypt data.
.RE
.PP
\-v \fIlevel\fR
.RS 4
Sets the debugging level.
.RE
.PP
\-y
.RS 4
Allows DNSSEC key files to be generated even if the key ID would collide with that of an existing key, in the event of either key being revoked. (This is only safe to use if you are sure you won't be using RFC 5011 trust anchor maintenance with either of the keys involved.)
.RE
.SH "TIMING OPTIONS"
.PP
Dates can be expressed in the format YYYYMMDD or YYYYMMDDHHMMSS. If the argument begins with a '+' or '\-', it is interpreted as an offset from the present time. For convenience, if such an offset is followed by one of the suffixes 'y', 'mo', 'w', 'd', 'h', or 'mi', then the offset is computed in years (defined as 365 24\-hour days, ignoring leap years), months (defined as 30 24\-hour days), weeks, days, hours, or minutes, respectively. Without a suffix, the offset is computed in seconds.
.PP
\-P \fIdate/offset\fR
.RS 4
Sets the date on which a key is to be published to the zone. After that date, the key will be included in the zone but will not be used to sign it. If not set, and if the \-G option has not been used, the default is "now".
.RE
.PP
\-A \fIdate/offset\fR
.RS 4
Sets the date on which the key is to be activated. After that date, the key will be included in the zone and used to sign it. If not set, and if the \-G option has not been used, the default is "now".
.RE
.PP
\-R \fIdate/offset\fR
.RS 4
Sets the date on which the key is to be revoked. After that date, the key will be flagged as revoked. It will be included in the zone and will be used to sign it.
.RE
.PP
\-U \fIdate/offset\fR
.RS 4
Sets the date on which the key is to be retired. After that date, the key will still be included in the zone, but it will not be used to sign it.
.RE
.PP
\-D \fIdate/offset\fR
.RS 4
Sets the date on which the key is to be deleted. After that date, the key will no longer be included in the zone. (It may remain in the key repository, however.)
.RE
.SH "GENERATED KEY FILES"
.PP
When
\fBdnssec\-keyfromlabel\fR
completes successfully, it prints a string of the form
\fIKnnnn.+aaa+iiiii\fR
to the standard output. This is an identification string for the key files it has generated.
.TP 4
\(bu
\fInnnn\fR
is the key name.
.TP 4
\(bu
\fIaaa\fR
is the numeric representation of the algorithm.
.TP 4
\(bu
\fIiiiii\fR
is the key identifier (or footprint).
.PP
\fBdnssec\-keyfromlabel\fR
creates two files, with names based on the printed string.
\fIKnnnn.+aaa+iiiii.key\fR
contains the public key, and
\fIKnnnn.+aaa+iiiii.private\fR
contains the private key.
.PP
The
\fI.key\fR
file contains a DNS KEY record that can be inserted into a zone file (directly or with a $INCLUDE statement).
.PP
The
\fI.private\fR
file contains algorithm\-specific fields. For obvious security reasons, this file does not have general read permission.
.SH "SEE ALSO"

<title>DESCRIPTION</title>
<para><command>dnssec-keyfromlabel</command>
gets keys with the given label from a crypto hardware and builds
key files for DNSSEC (Secure DNS), as defined in RFC 2535
and RFC 4034.
</para>
<para>
The <option>name</option> of the key is specified on the command
line. This must match the name of the zone for which the key is
being generated.
</para>

<title>OPTIONS</title>
<variablelist>
<varlistentry>
<term>-a <replaceable class="parameter">algorithm</replaceable></term>
<listitem>
<para>
Selects the cryptographic algorithm. The value of
<option>algorithm</option> must be one of RSAMD5, RSASHA1,
DSA, NSEC3RSASHA1, NSEC3DSA, RSASHA256 or RSASHA512.
These values are case insensitive.
</para>
<para>
If no algorithm is specified, then RSASHA1 will be used by
default, unless the <option>-3</option> option is specified,
in which case NSEC3RSASHA1 will be used instead. (If
<option>-3</option> is used and an algorithm is specified,
that algorithm will be checked for compatibility with NSEC3.)
</para>
<para>
Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement
algorithm, and DSA is recommended.
</para>
<para>
Note 2: DH automatically sets the -k flag.
</para>
</listitem>

<varlistentry>
<term>-n <replaceable class="parameter">nametype</replaceable></term>
<listitem>
<para>
Specifies the owner type of the key. The value of
<option>nametype</option> must either be ZONE (for a DNSSEC
zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with
a host (KEY)),
USER (for a key associated with a user(KEY)) or OTHER (DNSKEY).
These values are case insensitive.
</para>
</listitem>

<listitem>
<para>
Compatibility mode: generates an old-style key, without
any metadata. By default, <command>dnssec-keyfromlabel</command>
will include the key's creation date in the metadata stored
with the private key, and other dates may be set there as well
(publication date, activation date, etc). Keys that include
this data may be incompatible with older versions of BIND; the
<option>-C</option> option suppresses them.

<title>TIMING OPTIONS</title>
<para>
Dates can be expressed in the format YYYYMMDD or YYYYMMDDHHMMSS.
If the argument begins with a '+' or '-', it is interpreted as
an offset from the present time. For convenience, if such an offset
is followed by one of the suffixes 'y', 'mo', 'w', 'd', 'h', or 'mi',
then the offset is computed in years (defined as 365 24-hour days,
ignoring leap years), months (defined as 30 24-hour days), weeks,
days, hours, or minutes, respectively. Without a suffix, the offset
is computed in seconds.
</para>
<variablelist>
<varlistentry>
<term>-P <replaceable class="parameter">date/offset</replaceable></term>
<listitem>
<para>
Sets the date on which a key is to be published to the zone.
After that date, the key will be included in the zone but will
not be used to sign it. If not set, and if the -G option has
not been used, the default is "now".
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-A <replaceable class="parameter">date/offset</replaceable></term>
<listitem>
<para>
Sets the date on which the key is to be activated. After that
date, the key will be included in the zone and used to sign
it. If not set, and if the -G option has not been used, the
default is "now".
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-R <replaceable class="parameter">date/offset</replaceable></term>
<listitem>
<para>
Sets the date on which the key is to be revoked. After that
date, the key will be flagged as revoked. It will be included
in the zone and will be used to sign it.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-U <replaceable class="parameter">date/offset</replaceable></term>
<listitem>
<para>
Sets the date on which the key is to be retired. After that
date, the key will still be included in the zone, but it
will not be used to sign it.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-D <replaceable class="parameter">date/offset</replaceable></term>
<listitem>
<para>
Sets the date on which the key is to be deleted. After that
date, the key will no longer be included in the zone. (It
may remain in the key repository, however.)

<title>GENERATED KEY FILES</title>
<para>
When <command>dnssec-keyfromlabel</command> completes
successfully,
it prints a string of the form <filename>Knnnn.+aaa+iiiii</filename>
to the standard output. This is an identification string for
the key files it has generated.
</para>
<itemizedlist>
<listitem>
<para><filename>nnnn</filename> is the key name.
</para>
</listitem>
<listitem>
<para><filename>aaa</filename> is the numeric representation
of the algorithm.
</para>
</listitem>
<listitem>
<para><filename>iiiii</filename> is the key identifier (or
footprint).
</para>
</listitem>
</itemizedlist>
<para><command>dnssec-keyfromlabel</command>
creates two files, with names based
on the printed string. <filename>Knnnn.+aaa+iiiii.key</filename>
contains the public key, and
<filename>Knnnn.+aaa+iiiii.private</filename> contains the
private key.
</para>
<para>
The <filename>.key</filename> file contains a DNS KEY record
that
can be inserted into a zone file (directly or with a $INCLUDE
statement).
</para>
<para>
The <filename>.private</filename> file contains
algorithm-specific
fields. For obvious security reasons, this file does not have
general read permission.

.SH "DESCRIPTION"
.PP
\fBdnssec\-keygen\fR
generates keys for DNSSEC (Secure DNS), as defined in RFC 2535 and RFC 4034. It can also generate keys for use with TSIG (Transaction Signatures) as defined in RFC 2845, or TKEY (Transaction Key) as defined in RFC 2930.
.PP
The
\fBname\fR
of the key is specified on the command line. For DNSSEC keys, this must match the name of the zone for which the key is being generated.
.SH "OPTIONS"
.PP
\-a \fIalgorithm\fR
.RS 4
Selects the cryptographic algorithm. For DNSSEC keys, the value of
\fBalgorithm\fR
must be one of RSAMD5, RSASHA1, DSA, NSEC3RSASHA1, NSEC3DSA, RSASHA256 or RSASHA512. For TSIG/TKEY, the value must be DH (Diffie Hellman), HMAC\-MD5, HMAC\-SHA1, HMAC\-SHA224, HMAC\-SHA256, HMAC\-SHA384, or HMAC\-SHA512. These values are case insensitive.
.sp
If no algorithm is specified, then RSASHA1 will be used by default, unless the
\fB\-3\fR
option is specified, in which case NSEC3RSASHA1 will be used instead. (If
\fB\-3\fR
is used and an algorithm is specified, that algorithm will be checked for compatibility with NSEC3.)
.sp
Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement algorithm, and DSA is recommended. For TSIG, HMAC\-MD5 is mandatory.
.sp
Note 2: DH, HMAC\-MD5, and HMAC\-SHA1 through HMAC\-SHA512 automatically set the \-T KEY option.
.RE
.PP
\-b \fIkeysize\fR
.RS 4
Specifies the number of bits in the key. The choice of key size depends on the algorithm used. RSA keys must be between 512 and 2048 bits. Diffie Hellman keys must be between 128 and 4096 bits. DSA keys must be between 512 and 1024 bits and an exact multiple of 64. HMAC keys must be between 1 and 512 bits.
.sp
The key size does not need to be specified if using a default algorithm. The default key size is 1024 bits for zone signing keys (ZSK's) and 2048 bits for key signing keys (KSK's, generated with
\fB\-f KSK\fR). However, if an algorithm is explicitly specified with the
\fB\-a\fR, then there is no default key size, and the
\fB\-b\fR
must be used.
.RE
.PP
\-n \fInametype\fR
.RS 4
Specifies the owner type of the key. The value of
\fBnametype\fR
must either be ZONE (for a DNSSEC zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with a host (KEY)), USER (for a key associated with a user(KEY)) or OTHER (DNSKEY). These values are case insensitive. Defaults to ZONE for DNSKEY generation.
.RE
.PP
\-3
.RS 4
Use an NSEC3\-capable algorithm to generate a DNSSEC key. If this option is used and no algorithm is explicitly set on the command line, NSEC3RSASHA1 will be used by default. Note that RSASHA256 and RSASHA512 algorithms are NSEC3\-capable.
.RE
.PP
\-C
.RS 4
Compatibility mode: generates an old\-style key, without any metadata. By default,
\fBdnssec\-keygen\fR
will include the key's creation date in the metadata stored with the private key, and other dates may be set there as well (publication date, activation date, etc). Keys that include this data may be incompatible with older versions of BIND; the
\fB\-C\fR
option suppresses them.
.RE
.PP
\-c \fIclass\fR
.RS 4
Indicates that the DNS record containing the key should have the specified class. If not specified, class IN is used.
.RE
.PP
\-E \fIengine\fR
.RS 4
Uses a crypto hardware (OpenSSL engine) for random number and, when supported, key generation. When compiled with PKCS#11 support it defaults to pkcs11; the empty name resets it to no engine.
.RE
.PP
\-e
.RS 4
If generating an RSAMD5/RSASHA1 key, use a large exponent.
.RE
.PP
\-f \fIflag\fR
.RS 4
Set the specified flag in the flag field of the KEY/DNSKEY record. The only recognized flags are KSK (Key Signing Key) and REVOKE.
.RE
.PP
\-G
.RS 4
Generate a key, but do not publish it or sign with it. This option is incompatible with \-P and \-A.
.RE
.PP
\-g \fIgenerator\fR
.RS 4
If generating a Diffie Hellman key, use this generator. Allowed values are 2 and 5. If no generator is specified, a known prime from RFC 2539 will be used if possible; otherwise the default is 2.
.RE
.PP
\-h
.RS 4
Prints a short summary of the options and arguments to
\fBdnssec\-keygen\fR.
.RE
.PP
\-K \fIdirectory\fR
.RS 4
Sets the directory in which the key files are to be written.
.RE
.PP
\-k
.RS 4
Deprecated in favor of \-T KEY.
.RE
.PP
\-p \fIprotocol\fR
.RS 4
Sets the protocol value for the generated key. The protocol is a number between 0 and 255. The default is 3 (DNSSEC). Other possible values for this argument are listed in RFC 2535 and its successors.
.RE
.PP
\-q
.RS 4
Quiet mode: Suppresses unnecessary output, including progress indication. Without this option, when
\fBdnssec\-keygen\fR
is run interactively to generate an RSA or DSA key pair, it will print a string of symbols to
\fIstderr\fR
indicating the progress of the key generation. A '.' indicates that a random number has been found which passed an initial sieve test; '+' means a number has passed a single round of the Miller\-Rabin primality test; a space means that the number has passed all the tests and is a satisfactory key.
.RE
.PP
\-r \fIrandomdev\fR
.RS 4
Specifies the source of randomness. If the operating system does not provide a
\fI/dev/random\fR
or equivalent device, the default source of randomness is keyboard input.
\fIrandomdev\fR
specifies the name of a character device or file containing random data to be used instead of the default. The special value
\fIkeyboard\fR
indicates that keyboard input should be used.
.RE
.PP
\-s \fIstrength\fR
.RS 4
Specifies the strength value of the key. The strength is a number between 0 and 15, and currently has no defined purpose in DNSSEC.
.RE
.PP
\-T \fIrrtype\fR
.RS 4
Specifies the resource record type to use for the key.
\fBrrtype\fR
must be either DNSKEY or KEY. The default is DNSKEY when using a DNSSEC algorithm, but it can be overridden to KEY for use with SIG(0).
Using any TSIG algorithm (HMAC\-* or DH) forces this option to KEY.
.RE
.PP
\-t \fItype\fR
.RS 4
Indicates the use of the key.
\fBtype\fR
must be one of AUTHCONF, NOAUTHCONF, NOAUTH, or NOCONF. The default is AUTHCONF. AUTH refers to the ability to authenticate data, and CONF the ability to encrypt data.
.RE
.PP
\-v \fIlevel\fR
.RS 4
Sets the debugging level.
.RE
.SH "TIMING OPTIONS"
.PP
Dates can be expressed in the format YYYYMMDD or YYYYMMDDHHMMSS. If the argument begins with a '+' or '\-', it is interpreted as an offset from the present time. For convenience, if such an offset is followed by one of the suffixes 'y', 'mo', 'w', 'd', 'h', or 'mi', then the offset is computed in years (defined as 365 24\-hour days, ignoring leap years), months (defined as 30 24\-hour days), weeks, days, hours, or minutes, respectively. Without a suffix, the offset is computed in seconds.
.PP
\-P \fIdate/offset\fR
.RS 4
Sets the date on which a key is to be published to the zone. After that date, the key will be included in the zone but will not be used to sign it. If not set, and if the \-G option has not been used, the default is "now".
.RE
.PP
\-A \fIdate/offset\fR
.RS 4
Sets the date on which the key is to be activated. After that date, the key will be included in the zone and used to sign it. If not set, and if the \-G option has not been used, the default is "now".
.RE
.PP
\-R \fIdate/offset\fR
.RS 4
Sets the date on which the key is to be revoked. After that date, the key will be flagged as revoked. It will be included in the zone and will be used to sign it.
.RE
.PP
\-I \fIdate/offset\fR
.RS 4
Sets the date on which the key is to be retired. After that date, the key will still be included in the zone, but it will not be used to sign it.
.RE
.PP
\-D \fIdate/offset\fR
.RS 4
Sets the date on which the key is to be deleted. After that date, the key will no longer be included in the zone. (It may remain in the key repository, however.)
.RE
.SH "GENERATED KEYS"
.PP
When
\fBdnssec\-keygen\fR
completes successfully, it prints a string of the form
\fIKnnnn.+aaa+iiiii\fR
to the standard output. This is an identification string for the key it has generated.
.TP 4
\(bu
\fInnnn\fR
is the key name.
.TP 4
\(bu
\fIaaa\fR
is the numeric representation of the algorithm.
.TP 4
\(bu
\fIiiiii\fR
is the key identifier (or footprint).
.PP
\fBdnssec\-keygen\fR
creates two files, with names based on the printed string.
\fIKnnnn.+aaa+iiiii.key\fR
contains the public key, and
\fIKnnnn.+aaa+iiiii.private\fR
contains the private key.
.PP
The
\fI.key\fR
file contains a DNS KEY record that can be inserted into a zone file (directly or with a $INCLUDE statement).
.PP
The
\fI.private\fR
file contains algorithm\-specific fields. For obvious security reasons, this file does not have general read permission.
.PP
Both
\fI.key\fR
and
\fI.private\fR
files are generated for symmetric encryption algorithms such as HMAC\-MD5, even though the public and private key are equivalent.
.SH "EXAMPLE"
.PP
To generate a 768\-bit DSA key for the domain
\fBexample.com\fR, the following command would be issued:
.PP
\fBdnssec\-keygen \-a DSA \-b 768 \-n ZONE example.com\fR
.PP
The command would print a string of the form:
.PP
\fBKexample.com.+003+26160\fR
.PP
In this example,
\fBdnssec\-keygen\fR
creates the files
\fIKexample.com.+003+26160.key\fR
and
\fIKexample.com.+003+26160.private\fR.

<title>DESCRIPTION</title>
<para><command>dnssec-keygen</command>
generates keys for DNSSEC (Secure DNS), as defined in RFC 2535
and RFC 4034. It can also generate keys for use with
TSIG (Transaction Signatures) as defined in RFC 2845, or TKEY
(Transaction Key) as defined in RFC 2930.
</para>
<para>
The <option>name</option> of the key is specified on the command
line. For DNSSEC keys, this must match the name of the zone for
which the key is being generated.
</para>
</refsect1>
<refsect1>
<title>OPTIONS</title>
<variablelist>
<varlistentry>
<term>-a <replaceable class="parameter">algorithm</replaceable></term>
<listitem>
<para>
Selects the cryptographic algorithm. For DNSSEC keys, the value
of <option>algorithm</option> must be one of RSAMD5, RSASHA1,
DSA, NSEC3RSASHA1, NSEC3DSA, RSASHA256 or RSASHA512.
For TSIG/TKEY, the value must
be DH (Diffie Hellman), HMAC-MD5, HMAC-SHA1, HMAC-SHA224,
HMAC-SHA256, HMAC-SHA384, or HMAC-SHA512. These values are
case insensitive.
</para>
<para>
If no algorithm is specified, then RSASHA1 will be used by
default, unless the <option>-3</option> option is specified,
in which case NSEC3RSASHA1 will be used instead. (If
<option>-3</option> is used and an algorithm is specified,
that algorithm will be checked for compatibility with NSEC3.)
</para>
<para>
Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement
algorithm, and DSA is recommended. For TSIG, HMAC-MD5 is
mandatory.
</para>
<para>
Note 2: DH, HMAC-MD5, and HMAC-SHA1 through HMAC-SHA512
automatically set the -T KEY option.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-b <replaceable class="parameter">keysize</replaceable></term>
<listitem>
<para>
Specifies the number of bits in the key. The choice of key
size depends on the algorithm used. RSA keys must be
between 512 and 2048 bits. Diffie Hellman keys must be between
128 and 4096 bits. DSA keys must be between 512 and 1024
bits and an exact multiple of 64. HMAC keys must be
between 1 and 512 bits.
</para>
<para>
The key size does not need to be specified if using a default
algorithm. The default key size is 1024 bits for zone signing
keys (ZSK's) and 2048 bits for key signing keys (KSK's,
generated with <option>-f KSK</option>). However, if an
algorithm is explicitly specified with the <option>-a</option>,
then there is no default key size, and the <option>-b</option>
must be used.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-n <replaceable class="parameter">nametype</replaceable></term>
<listitem>
<para>
Specifies the owner type of the key. The value of
<option>nametype</option> must either be ZONE (for a DNSSEC
zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with
a host (KEY)),
USER (for a key associated with a user(KEY)) or OTHER (DNSKEY).
These values are case insensitive. Defaults to ZONE for DNSKEY
generation.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-3</term>
<listitem>
<para>
Use an NSEC3-capable algorithm to generate a DNSSEC key.
If this option is used and no algorithm is explicitly
set on the command line, NSEC3RSASHA1 will be used by
default. Note that RSASHA256 and RSASHA512 algorithms
are NSEC3-capable.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-C</term>
<listitem>
<para>
Compatibility mode: generates an old-style key, without
any metadata. By default, <command>dnssec-keygen</command>
will include the key's creation date in the metadata stored
with the private key, and other dates may be set there as well
(publication date, activation date, etc). Keys that include
this data may be incompatible with older versions of BIND; the
<option>-C</option> option suppresses them.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-c <replaceable class="parameter">class</replaceable></term>
<listitem>
<para>
Indicates that the DNS record containing the key should have
the specified class. If not specified, class IN is used.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-E <replaceable class="parameter">engine</replaceable></term>
<listitem>
<para>
Uses a crypto hardware (OpenSSL engine) for random number
and, when supported, key generation. When compiled with PKCS#11
support it defaults to pkcs11; the empty name resets it to
no engine.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-e</term>
<listitem>
<para>
If generating an RSAMD5/RSASHA1 key, use a large exponent.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-f <replaceable class="parameter">flag</replaceable></term>
<listitem>
<para>
Set the specified flag in the flag field of the KEY/DNSKEY record.
The only recognized flags are KSK (Key Signing Key) and REVOKE.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-G</term>
<listitem>
<para>
Generate a key, but do not publish it or sign with it. This
option is incompatible with -P and -A.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-g <replaceable class="parameter">generator</replaceable></term>
<listitem>
<para>
If generating a Diffie Hellman key, use this generator.
Allowed values are 2 and 5. If no generator
is specified, a known prime from RFC 2539 will be used
if possible; otherwise the default is 2.
</para>
</listitem>

</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-p <replaceable class="parameter">protocol</replaceable></term>
<listitem>
<para>
Sets the protocol value for the generated key. The protocol
is a number between 0 and 255. The default is 3 (DNSSEC).
Other possible values for this argument are listed in
RFC 2535 and its successors.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-q</term>
<listitem>
<para>
Quiet mode: Suppresses unnecessary output, including
progress indication. Without this option, when
<command>dnssec-keygen</command> is run interactively
to generate an RSA or DSA key pair, it will print a string
of symbols to <filename>stderr</filename> indicating the
progress of the key generation. A '.' indicates that a
random number has been found which passed an initial
sieve test; '+' means a number has passed a single
round of the Miller-Rabin primality test; a space
means that the number has passed all the tests and is
a satisfactory key.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-r <replaceable class="parameter">randomdev</replaceable></term>
<listitem>
<para>
Specifies the source of randomness. If the operating
system does not provide a <filename>/dev/random</filename>
or equivalent device, the default source of randomness
is keyboard input. <filename>randomdev</filename>
specifies
the name of a character device or file containing random
data to be used instead of the default. The special value
<filename>keyboard</filename> indicates that keyboard
input should be used.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-s <replaceable class="parameter">strength</replaceable></term>
<listitem>
<para>
Specifies the strength value of the key. The strength is
a number between 0 and 15, and currently has no defined
purpose in DNSSEC.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-T <replaceable class="parameter">rrtype</replaceable></term>
<listitem>
<para>
Specifies the resource record type to use for the key.
<option>rrtype</option> must be either DNSKEY or KEY. The
default is DNSKEY when using a DNSSEC algorithm, but it can be
overridden to KEY for use with SIG(0).
<para>
</para>
Using any TSIG algorithm (HMAC-* or DH) forces this option
to KEY.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-t <replaceable class="parameter">type</replaceable></term>
<listitem>
<para>
Indicates the use of the key. <option>type</option> must be
one of AUTHCONF, NOAUTHCONF, NOAUTH, or NOCONF. The default
is AUTHCONF. AUTH refers to the ability to authenticate
data, and CONF the ability to encrypt data.
</para>
</listitem>
</varlistentry>

<title>TIMING OPTIONS</title>
<para>
Dates can be expressed in the format YYYYMMDD or YYYYMMDDHHMMSS.
If the argument begins with a '+' or '-', it is interpreted as
an offset from the present time. For convenience, if such an offset
is followed by one of the suffixes 'y', 'mo', 'w', 'd', 'h', or 'mi',
then the offset is computed in years (defined as 365 24-hour days,
ignoring leap years), months (defined as 30 24-hour days), weeks,
days, hours, or minutes, respectively. Without a suffix, the offset
is computed in seconds.
</para>
<variablelist>
<varlistentry>
<term>-P <replaceable class="parameter">date/offset</replaceable></term>
<listitem>
<para>
Sets the date on which a key is to be published to the zone.
After that date, the key will be included in the zone but will
not be used to sign it. If not set, and if the -G option has
not been used, the default is "now".
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-A <replaceable class="parameter">date/offset</replaceable></term>
<listitem>
<para>
Sets the date on which the key is to be activated. After that
date, the key will be included in the zone and used to sign
it. If not set, and if the -G option has not been used, the
default is "now".
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-R <replaceable class="parameter">date/offset</replaceable></term>
<listitem>
<para>
Sets the date on which the key is to be revoked. After that
date, the key will be flagged as revoked. It will be included
in the zone and will be used to sign it.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-I <replaceable class="parameter">date/offset</replaceable></term>
<listitem>
<para>
Sets the date on which the key is to be retired. After that
date, the key will still be included in the zone, but it
will not be used to sign it.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-D <replaceable class="parameter">date/offset</replaceable></term>
<listitem>
<para>
Sets the date on which the key is to be deleted. After that
date, the key will no longer be included in the zone. (It
may remain in the key repository, however.)

<title>GENERATED KEYS</title>
<para>
When <command>dnssec-keygen</command> completes
successfully,
it prints a string of the form <filename>Knnnn.+aaa+iiiii</filename>
to the standard output. This is an identification string for
the key it has generated.
</para>
<itemizedlist>
<listitem>
<para><filename>nnnn</filename> is the key name.
</para>
</listitem>
<listitem>
<para><filename>aaa</filename> is the numeric representation
of the
algorithm.
</para>
</listitem>
<listitem>
<para><filename>iiiii</filename> is the key identifier (or
footprint).
</para>
</listitem>
</itemizedlist>
<para><command>dnssec-keygen</command>
creates two files, with names based
on the printed string. <filename>Knnnn.+aaa+iiiii.key</filename>
contains the public key, and
<filename>Knnnn.+aaa+iiiii.private</filename> contains the
private
key.
</para>
<para>
The <filename>.key</filename> file contains a DNS KEY record
that
can be inserted into a zone file (directly or with a $INCLUDE
statement).
</para>
<para>
The <filename>.private</filename> file contains
algorithm-specific
fields. For obvious security reasons, this file does not have
general read permission.
</para>
<para>
Both <filename>.key</filename> and <filename>.private</filename>
files are generated for symmetric encryption algorithms such as
HMAC-MD5, even though the public and private key are equivalent.
</para>
</refsect1>
<refsect1>
<title>EXAMPLE</title>
<para>
To generate a 768-bit DSA key for the domain
<userinput>example.com</userinput>, the following command would be
issued:
</para>
<para><userinput>dnssec-keygen -a DSA -b 768 -n ZONE example.com</userinput>
</para>
<para>
The command would print a string of the form:
</para>
<para><userinput>Kexample.com.+003+26160</userinput>
</para>
<para>
In this example, <command>dnssec-keygen</command> creates
the files <filename>Kexample.com.+003+26160.key</filename>
and
<filename>Kexample.com.+003+26160.private</filename>.

If generating a Diffie Hellman key, use this generator.
Allowed values are 2 and 5. If no generator

<dt><span class="term">-K <em class="replaceable"><code>directory</code></em></span></dt>
<dd><p>
Sets the directory in which the key files are to be written.
</p></dd>
<dt><span class="term">-k</span></dt>
<dd><p>
Deprecated in favor of -T KEY.
</p></dd>
<dt><span class="term">-p <em class="replaceable"><code>protocol</code></em></span></dt>
<dd><p>
Sets the protocol value for the generated key. The protocol
is a number between 0 and 255. The default is 3 (DNSSEC).
Other possible values for this argument are listed in
RFC 2535 and its successors.
</p></dd>
<dt><span class="term">-q</span></dt>
<dd><p>
Quiet mode: Suppresses unnecessary output, including
progress indication. Without this option, when
<span><strong class="command">dnssec-keygen</strong></span> is run interactively
to generate an RSA or DSA key pair, it will print a string
of symbols to <code class="filename">stderr</code> indicating the
progress of the key generation. A '.' indicates that a
random number has been found which passed an initial
sieve test; '+' means a number has passed a single
round of the Miller-Rabin primality test; a space
means that the number has passed all the tests and is
a satisfactory key.
</p></dd>
<dt><span class="term">-r <em class="replaceable"><code>randomdev</code></em></span></dt>
<dd><p>
Specifies the source of randomness. If the operating
system does not provide a <code class="filename">/dev/random</code>
or equivalent device, the default source of randomness
is keyboard input. <code class="filename">randomdev</code>
specifies
the name of a character device or file containing random
data to be used instead of the default. The special value
<code class="filename">keyboard</code> indicates that keyboard
input should be used.
</p></dd>
<dt><span class="term">-s <em class="replaceable"><code>strength</code></em></span></dt>
<dd><p>
Specifies the strength value of the key. The strength is
a number between 0 and 15, and currently has no defined
purpose in DNSSEC.

<dt><span class="term">-T <em class="replaceable"><code>rrtype</code></em></span></dt>
<dd>
<p>
Specifies the resource record type to use for the key.
<code class="option">rrtype</code> must be either DNSKEY or KEY. The
default is DNSKEY when using a DNSSEC algorithm, but it can be
overridden to KEY for use with SIG(0).

Using any TSIG algorithm (HMAC-* or DH) forces this option
to KEY.
</p>
</dd>
<dt><span class="term">-t <em class="replaceable"><code>type</code></em></span></dt>
<dd><p>
Indicates the use of the key. <code class="option">type</code> must be
one of AUTHCONF, NOAUTHCONF, NOAUTH, or NOCONF. The default
is AUTHCONF. AUTH refers to the ability to authenticate
data, and CONF the ability to encrypt data.

<a name="id2544128"></a><h2>TIMING OPTIONS</h2>
<p>
Dates can be expressed in the format YYYYMMDD or YYYYMMDDHHMMSS.
If the argument begins with a '+' or '-', it is interpreted as
an offset from the present time. For convenience, if such an offset
is followed by one of the suffixes 'y', 'mo', 'w', 'd', 'h', or 'mi',
then the offset is computed in years (defined as 365 24-hour days,
ignoring leap years), months (defined as 30 24-hour days), weeks,
days, hours, or minutes, respectively. Without a suffix, the offset
is computed in seconds.
</p>
<div class="variablelist"><dl>
<dt><span class="term">-P <em class="replaceable"><code>date/offset</code></em></span></dt>
<dd><p>
Sets the date on which a key is to be published to the zone.
After that date, the key will be included in the zone but will
not be used to sign it. If not set, and if the -G option has
not been used, the default is "now".
</p></dd>
<dt><span class="term">-A <em class="replaceable"><code>date/offset</code></em></span></dt>
<dd><p>
Sets the date on which the key is to be activated. After that
date, the key will be included in the zone and used to sign
it. If not set, and if the -G option has not been used, the
default is "now".
</p></dd>
<dt><span class="term">-R <em class="replaceable"><code>date/offset</code></em></span></dt>
<dd><p>
Sets the date on which the key is to be revoked. After that
date, the key will be flagged as revoked. It will be included
in the zone and will be used to sign it.
</p></dd>
<dt><span class="term">-I <em class="replaceable"><code>date/offset</code></em></span></dt>
<dd><p>
Sets the date on which the key is to be retired. After that
date, the key will still be included in the zone, but it
will not be used to sign it.
</p></dd>
<dt><span class="term">-D <em class="replaceable"><code>date/offset</code></em></span></dt>
<dd><p>
Sets the date on which the key is to be deleted. After that
date, the key will no longer be included in the zone. (It
may remain in the key repository, however.)

<a name="id2544226"></a><h2>GENERATED KEYS</h2>
<p>
When <span><strong class="command">dnssec-keygen</strong></span> completes
successfully,
it prints a string of the form <code class="filename">Knnnn.+aaa+iiiii</code>
to the standard output. This is an identification string for
the key it has generated.
</p>
<div class="itemizedlist"><ul type="disc">
<li><p><code class="filename">nnnn</code> is the key name.
</p></li>
<li><p><code class="filename">aaa</code> is the numeric representation
of the
algorithm.
</p></li>
<li><p><code class="filename">iiiii</code> is the key identifier (or
footprint).
</p></li>
</ul></div>
<p><span><strong class="command">dnssec-keygen</strong></span>
creates two files, with names based
on the printed string. <code class="filename">Knnnn.+aaa+iiiii.key</code>
contains the public key, and
<code class="filename">Knnnn.+aaa+iiiii.private</code> contains the
private
key.
</p>
<p>
The <code class="filename">.key</code> file contains a DNS KEY record
that
can be inserted into a zone file (directly or with a $INCLUDE
statement).
</p>
<p>
The <code class="filename">.private</code> file contains
algorithm-specific
fields. For obvious security reasons, this file does not have
general read permission.
</p>
<p>
Both <code class="filename">.key</code> and <code class="filename">.private</code>
files are generated for symmetric encryption algorithms such as
HMAC-MD5, even though the public and private key are equivalent.
</p>
</div>
<div class="refsect1" lang="en">
<a name="id2544308"></a><h2>EXAMPLE</h2>
<p>
To generate a 768-bit DSA key for the domain
<strong class="userinput"><code>example.com</code></strong>, the following command would be
issued:
</p>
<p><strong class="userinput"><code>dnssec-keygen -a DSA -b 768 -n ZONE example.com</code></strong>
</p>
<p>
The command would print a string of the form:
</p>
<p><strong class="userinput"><code>Kexample.com.+003+26160</code></strong>
</p>
<p>
In this example, <span><strong class="command">dnssec-keygen</strong></span> creates
the files <code class="filename">Kexample.com.+003+26160.key</code>
and
<code class="filename">Kexample.com.+003+26160.private</code>.
