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.
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.
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?
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).
The relevant modules can be loaded by running:
modprobe commoncap
modprobe capability
Q: I'm running BIND on Red Hat Enterprise Linux or Fedora Core -
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: Red Hat Security Enhanced Linux (SELinux) policy security protections :
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:
$ROOTDIR/var/named/slaves
$ROOTDIR/var/named/data
$ROOTDIR/var/tmp
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.
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.
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";
};
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";
...
};
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.
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:
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}}
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 .
To create a custom configuration file location, e.g. '/root/
named.conf', to use with the 'named -c' option, do:
# chcon system_u:object_r:named_conf_t /root/named.conf
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.
configuration files on my Linux sysetm 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
should also be owned by root.

BIND 9.3.6
BIND 9.3.6 is a maintenance release, containing fixes for
a number of bugs in previous releases.
The major change since 9.3.5 is query port randomization,
to improve resilience against cache poisoning attacks.
BIND 9.1.0b1
BIND 9.3.2
BIND 9.1.0b1 is the first beta release of BIND 9.1.0.
It includes a number of new features:
BIND 9.3.2 is a maintenance release, containing fixes for
a number of bugs in 9.3.1.
- 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
libbind: corresponds to that from BIND 8.4.7-REL.
- Forwarding of dynamic update requests; this is enabled
by the "allow-update-forwarding" option
Known Issues:
- A new, simplified database interface and a number of
sample drivers based on it; see doc/dev/sdb for details
The following INSIST can be triggered with DNSSEC enabled.
- Support for building single-threaded servers for
environments that do not supply POSIX threads
resolver.c:762: INSIST(result != 0 || dns_rdataset_isassociated(event->rdataset) || fctx->type == ((dns_rdatatype_t)dns_rdatatype_any) || fctx->type == ((dns_rdatatype_t)dns_rdatatype_rrsig)) failed
- New configuration options: "min-refresh-time",
"max-refresh-time", "min-retry-time", "max-retry-time",
"additional-from-auth", "additional-from-cache",
"notify explicit"
We are still trying to isolate the cause. If you have core
dump please send a bug report to bind9-bugs@isc.org with
the location of the core, named executable and OS details.
Note: contrib/nanny contains a perl script to restart named
in the event of a INSIST/REQUIRE/ENSURE failure.
- Faster lookups, particularly in large zones.
BIND 9.3.1
BIND 9.1.0 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.
BIND 9.3.1 is a maintenance release, containing fixes for
a number of bugs in 9.3.0.
Cryptographic operations are now based on the OpenSSL
library instead of DNSsafe.
libbind: corresponds to that from BIND 8.4.6-REL.
Numerous bugs have been fixed.
BIND 9.3.0
BIND 9.1.0 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.
BIND 9.3.0 has a number of new features over 9.2,
including:
DNSSEC is now DS based (RFC 3658).
See also RFC 3845, doc/draft/draft-ietf-dnsext-dnssec-*.
DNSSEC lookaside validation.
check-names is now implemented.
rrset-order in more complete.
IPv4/IPv6 transition support, dual-stack-servers.
IXFR deltas can now be generated when loading master files,
ixfr-from-differences.
It is now possible to specify the size of a journal, max-journal-size.
It is now possible to define a named set of master servers to be
used in masters clause, masters.
The advertised EDNS UDP size can now be set, edns-udp-size.
allow-v6-synthesis has been obsoleted.
NOTE:
* Zones containing MD and MF will now be rejected.
* dig, nslookup name. now report "Not Implemented" as
NOTIMP rather than NOTIMPL. This will have impact on scripts
that are looking for NOTIMPL.
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

BUILD_LDFLAGS (optional)

To build shared libraries, specify "--with-libtool" on the
configure command line.
For the server to support DNSSEC, you need to build it
with crypto support. You must have OpenSSL 0.9.5a
or newer installed and specify "--with-openssl" on the
configure command line. If OpenSSL is installed under
a nonstandard prefix, you can tell configure where to
look for it using "--with-openssl=/prefix".
To build libbind (the BIND 8 resolver library), specify
"--enable-libbind" on the configure command line.
On some platforms it is necessary to explictly request large
file support to handle files bigger than 2GB. This can be
done by "--enable-largefile" on the configure command line.
On some platforms, BIND 9 can be built with multithreading
support, allowing it to take advantage of multiple CPUs.
You can specify whether to build a multithreaded BIND 9
by specifying "--enable-threads" or "--disable-threads"
on the configure command line. The default is operating
system dependent.
To build without multithreading, specify "--disable-threads"
on the configure command line.
If your operating system has integrated support for IPv6, it
will be used automatically. If you have installed KAME IPv6
separately, use "--with-kame[=PATH]" to specify its location.
To see additional configure options, run "configure --help".
"make install" will install "named" and the various BIND 9 libraries.
By default, installation is into /usr/local, but this can be changed
with the "--prefix" option when running "configure".
You may specify the option "--sysconfdir" to set the directory
where configuration files like "named.conf" go by default,
and "--localstatedir" to set the default parent directory
of "run/named.pid". For backwards compatibility with BIND 8,
--sysconfdir defaults to "/etc" and --localstatedir defaults to
"/var" if no --prefix option is given. If there is a --prefix
option, sysconfdir defaults to "$prefix/etc" and localstatedir
defaults to "$prefix/var".
To see additional configure options, run "configure --help".
Note that the help message does not reflect the BIND 8
compatibility defaults for sysconfdir and localstatedir.
If you're planning on making changes to the BIND 9 source, you
should also "make depend". If you're using Emacs, you might find
"make tags" helpful.
If you need to re-run configure please run "make distclean" first.
This will ensure that all the option changes take.
Building with gcc is not supported, unless gcc is the vendor's usual
compiler (e.g. the various BSD systems, Linux).
Known compiler issues:
* gcc-3.2.1 and gcc-3.1.1 is known to cause problems with solaris-x86.
* gcc prior to gcc-3.2.3 ultrasparc generates incorrect code at -02.
* gcc-3.3.5 powerpc generates incorrect code at -02.
* Irix, MipsPRO 7.4.1m is known to cause problems.
A limited test suite can be run with "make test". Many of
the tests require you to configure a set of virtual IP addresses
on your system, and some require Perl; see bin/tests/system/README
for details.
SunOS 4 requires "printf" to be installed to make the shared
libraries. sh-utils-1.16 provides a "printf" which compiles
on SunOS 4.

named\-checkzone \- zone file validity checking tool
.SH "SYNOPSIS"
.HP 16
\fBnamed\-checkzone\fR [\fB\-d\fR] [\fB\-j\fR] [\fB\-q\fR] [\fB\-v\fR] [\fB\-c\ \fR\fB\fIclass\fR\fR] [\fB\-k\ \fR\fB\fImode\fR\fR] [\fB\-n\ \fR\fB\fImode\fR\fR] [\fB\-o\ \fR\fB\fIfilename\fR\fR] [\fB\-t\ \fR\fB\fIdirectory\fR\fR] [\fB\-w\ \fR\fB\fIdirectory\fR\fR] [\fB\-D\fR] {zonename} {filename}
.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.
.SH "OPTIONS"
.PP
\-d
.RS 4
Enable debugging.
.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
\-k \fImode\fR
.RS 4
Perform
\fB"check\-names"\fR
checks with the specified failure mode. 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,
\fB"warn"\fR
(default) and
\fB"ignore"\fR.
.RE
.PP
\-o \fIfilename\fR
.RS 4
Write zone output to
\fIfilename\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.
.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"
.PP

.SH "DESCRIPTION"
.PP
\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, 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
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;
\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

.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

.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

bytes. The maximum and minimum sizes of this buffer are 65535 and 0 respectively. Values outside this range are rounded up or down appropriately.
.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
.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.

<title>DESCRIPTION</title>
<para>
<command>dig</command> (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 <command>dig</command> to
troubleshoot DNS problems because of its flexibility, ease of use and
clarity of output. Other lookup tools tend to have less functionality
than <command>dig</command>.
</para>
<para>
Although <command>dig</command> 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 <option>-h</option> option is given.
Unlike earlier versions, the BIND 9 implementation of
<command>dig</command> allows multiple lookups to be issued from the
command line.
</para>
<para>
Unless it is told to query a specific name server,
<command>dig</command> will try each of the servers listed in
<filename>/etc/resolv.conf</filename>.
</para>
<para>
When no command line arguments or options are given,
<command>dig</command> will perform an NS query for "." (the root).
</para>
<para>
It is possible to set per-user defaults for <command>dig</command> via
<filename>${HOME}/.digrc</filename>. This file is read and any options in it
are applied before the command line arguments.
</para>
<para>
The IN and CH class names overlap with the IN and CH top level
domains names. Either use the <option>-t</option> and
<option>-c</option> options to specify the type and class, or
use "IN." and "CH." when looking up these top level domains.
</para>
</refsect1>
<refsect1>
<title>SIMPLE USAGE</title>
<para>
A typical invocation of <command>dig</command> looks like:
<programlisting> dig @server name type </programlisting> where:
<variablelist>
<varlistentry><term><constant>server</constant></term>
<listitem><para>
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
<parameter>server</parameter> argument is a hostname,
<command>dig</command> resolves that name before querying that name
server. If no <parameter>server</parameter> argument is provided,
<command>dig</command> consults <filename>/etc/resolv.conf</filename>
and queries the name servers listed there. The reply from the name
server that responds is displayed.
</para></listitem></varlistentry>
<varlistentry><term><constant>name</constant></term>
<listitem><para>
is the name of the resource record that is to be looked up.
</para></listitem></varlistentry>
<varlistentry><term><constant>type</constant></term>
<listitem><para>
indicates what type of query is required &mdash;
ANY, A, MX, SIG, etc.
<parameter>type</parameter> can be any valid query type. If no
<parameter>type</parameter> argument is supplied,
<command>dig</command> will perform a lookup for an A record.
</para></listitem></varlistentry>
</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>
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>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>

<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>.

<a name="id2543493"></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, or
use "IN." and "CH." when looking up these top level domains.
</p>
</div>
<div class="refsect1" lang="en">
<a name="id2543565"></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="id2543644"></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>
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>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="id2543837"></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
behavior is to use UDP unless an AXFR or IXFR query is 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>
Ignore truncation in UDP responses instead of retrying with TCP. By
default, TCP retries are performed.
</p></dd>
<dt><span class="term"><code class="option">+domain=somename</code></span></dt>
<dd><p>
Set the search list to contain the single domain
<em class="parameter"><code>somename</code></em>, as if specified in a
<span><strong class="command">domain</strong></span> directive in
<code class="filename">/etc/resolv.conf</code>, and enable search list
processing as if the <em class="parameter"><code>+search</code></em> option were given.
</p></dd>
<dt><span class="term"><code class="option">+[no]search</code></span></dt>
<dd><p>
Use [do not use] the search list defined by the searchlist or domain
directive in <code class="filename">resolv.conf</code> (if any).
The search list is not used by default.
</p></dd>
<dt><span class="term"><code class="option">+[no]defname</code></span></dt>
<dd><p>
Deprecated, treated as a synonym for <em class="parameter"><code>+[no]search</code></em>
</p></dd>
<dt><span class="term"><code class="option">+[no]aaonly</code></span></dt>
<dd><p>
Sets the "aa" flag in the query.
</p></dd>
<dt><span class="term"><code class="option">+[no]aaflag</code></span></dt>
<dd><p>
A synonym for <em class="parameter"><code>+[no]aaonly</code></em>.
</p></dd>
<dt><span class="term"><code class="option">+[no]adflag</code></span></dt>
<dd><p>
Set [do not set] the AD (authentic data) bit in the query. The AD bit
currently has a standard meaning only in responses, not in queries,
but the ability to set the bit in the query is provided for
completeness.
</p></dd>
<dt><span class="term"><code class="option">+[no]cdflag</code></span></dt>
<dd><p>
Set [do not set] the CD (checking disabled) bit in the query. This
requests the server to not perform DNSSEC validation of responses.
</p></dd>
<dt><span class="term"><code class="option">+[no]cl</code></span></dt>
<dd><p>
Display [do not display] the CLASS when printing the record.
</p></dd>
<dt><span class="term"><code class="option">+[no]ttlid</code></span></dt>
<dd><p>
Display [do not display] the TTL when printing the record.
</p></dd>
<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
<em class="parameter"><code>+trace</code></em> query options are used.
</p></dd>
<dt><span class="term"><code class="option">+[no]nssearch</code></span></dt>
<dd><p>
When this option is set, <span><strong class="command">dig</strong></span> 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.
</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
root servers, showing the answer from each server that was used to
resolve the lookup.
</p></dd>
<dt><span class="term"><code class="option">+[no]cmd</code></span></dt>
<dd><p>
Toggles the printing of the initial comment in the output identifying
the version of <span><strong class="command">dig</strong></span> and the query options that have
been applied. This comment is printed by default.
</p></dd>
<dt><span class="term"><code class="option">+[no]short</code></span></dt>
<dd><p>
Provide a terse answer. The default is to print the answer in a
verbose form.
</p></dd>
<dt><span class="term"><code class="option">+[no]identify</code></span></dt>
<dd><p>
Show [or do not show] the IP address and port number that supplied the
answer when the <em class="parameter"><code>+short</code></em> 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.
</p></dd>
<dt><span class="term"><code class="option">+[no]comments</code></span></dt>
<dd><p>
Toggle the display of comment lines in the output. The default is to
print comments.
</p></dd>
<dt><span class="term"><code class="option">+[no]stats</code></span></dt>
<dd><p>
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.
</p></dd>
<dt><span class="term"><code class="option">+[no]qr</code></span></dt>
<dd><p>
Print [do not print] the query as it is sent.
By default, the query is not printed.
</p></dd>
<dt><span class="term"><code class="option">+[no]question</code></span></dt>
<dd><p>
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.

<a name="id2544574"></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>.

host \- DNS lookup utility
.SH "SYNOPSIS"
.HP 5
\fBhost\fR [\fB\-aCdlnrTwv\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\-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.

<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.

<a name="id2543414"></a><h2>DESCRIPTION</h2>
<p>
<span><strong class="command">host</strong></span>
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,
<span><strong class="command">host</strong></span>
prints a short summary of its command line arguments and options.
</p>
<p>
<em class="parameter"><code>name</code></em> 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 <span><strong class="command">host</strong></span> will by default
perform a reverse lookup for that address.
<em class="parameter"><code>server</code></em> is an optional argument which is either
the name or IP address of the name server that <span><strong class="command">host</strong></span>
should query instead of the server or servers listed in
<code class="filename">/etc/resolv.conf</code>.
</p>
<p>
The <code class="option">-a</code> (all) option is equivalent to setting the
<code class="option">-v</code> option and asking <span><strong class="command">host</strong></span> to make
a query of type ANY.
</p>
<p>
When the <code class="option">-C</code> option is used, <span><strong class="command">host</strong></span>
will attempt to display the SOA records for zone
<em class="parameter"><code>name</code></em> 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.
</p>
<p>
The <code class="option">-c</code> option instructs to make a DNS query of class
<em class="parameter"><code>class</code></em>. This can be used to lookup Hesiod or
Chaosnet class resource records. The default class is IN (Internet).
</p>
<p>
Verbose output is generated by <span><strong class="command">host</strong></span> when the
<code class="option">-d</code> or <code class="option">-v</code> option is used. The two
options are equivalent. They have been provided for backwards
compatibility. In previous versions, the <code class="option">-d</code> option
switched on debugging traces and <code class="option">-v</code> enabled verbose
output.
</p>
<p>
List mode is selected by the <code class="option">-l</code> option. This makes
<span><strong class="command">host</strong></span> perform a zone transfer for zone
<em class="parameter"><code>name</code></em>. Transfer the zone printing out the NS, PTR
and address records (A/AAAA). If combined with <code class="option">-a</code>
all records will be printed.
</p>
<p>
The <code class="option">-i</code>
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.
</p>
<p>
The <code class="option">-N</code> option sets the number of dots that have to be
in <em class="parameter"><code>name</code></em> for it to be considered absolute. The
default value is that defined using the ndots statement in
<code class="filename">/etc/resolv.conf</code>, 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 <span class="type">search</span>
or <span class="type">domain</span> directive in
<code class="filename">/etc/resolv.conf</code>.
</p>
<p>
The number of UDP retries for a lookup can be changed with the
<code class="option">-R</code> option. <em class="parameter"><code>number</code></em> indicates
how many times <span><strong class="command">host</strong></span> will repeat a query that does
not get answered. The default number of retries is 1. If
<em class="parameter"><code>number</code></em> is negative or zero, the number of
retries will default to 1.
</p>
<p>
Non-recursive queries can be made via the <code class="option">-r</code> option.
Setting this option clears the <span class="type">RD</span> &#8212; recursion
desired &#8212; bit in the query which <span><strong class="command">host</strong></span> makes.
This should mean that the name server receiving the query will not
attempt to resolve <em class="parameter"><code>name</code></em>. The
<code class="option">-r</code> option enables <span><strong class="command">host</strong></span> 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.
</p>
<p>
By default <span><strong class="command">host</strong></span> uses UDP when making queries. The
<code class="option">-T</code> 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.
</p>
<p>
The <code class="option">-4</code> option forces <span><strong class="command">host</strong></span> to only
use IPv4 query transport. The <code class="option">-6</code> option forces
<span><strong class="command">host</strong></span> to only use IPv6 query transport.
</p>
<p>
The <code class="option">-t</code> option is used to select the query type.
<em class="parameter"><code>type</code></em> can be any recognized query type: CNAME,
NS, SOA, SIG, KEY, AXFR, etc. When no query type is specified,
<span><strong class="command">host</strong></span> automatically selects an appropriate query
type. By default it looks for A, AAAA, and MX records, but if the
<code class="option">-C</code> option was given, queries will be made for SOA
records, and if <em class="parameter"><code>name</code></em> is a dotted-decimal IPv4
address or colon-delimited IPv6 address, <span><strong class="command">host</strong></span> 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).
</p>
<p>
The time to wait for a reply can be controlled through the
<code class="option">-W</code> and <code class="option">-w</code> options. The
<code class="option">-W</code> option makes <span><strong class="command">host</strong></span> wait for
<em class="parameter"><code>wait</code></em> seconds. If <em class="parameter"><code>wait</code></em>
is less than one, the wait interval is set to one second. When the
<code class="option">-w</code> option is used, <span><strong class="command">host</strong></span> 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.

.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>

<p>
Interactive mode is entered in the following cases:

.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.
.SH "OPTIONS"
.PP
\-a \fIalgorithm\fR
.RS 4
Selects the cryptographic algorithm. The value of
\fBalgorithm\fR
must be one of RSAMD5 (RSA) or RSASHA1, DSA, DH (Diffie Hellman), or HMAC\-MD5. These values are case insensitive.
.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: HMAC\-MD5 and DH automatically set the \-k flag.
.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. RSAMD5 / RSASHA1 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\-MD5 keys must be between 1 and 512 bits.
.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 \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
.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 flag is KSK (Key Signing Key) DNSKEY.
.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
.RS 4
Generate KEY records rather than DNSKEY records.
.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
\-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 \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 "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.

<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 (RSA) or RSASHA1,
DSA, DH (Diffie Hellman), or HMAC-MD5. These values
are case insensitive.
</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: HMAC-MD5 and DH automatically set the -k flag.
</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. RSAMD5 / RSASHA1 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-MD5 keys must be
between 1 and 512 bits.
</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.
</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</term>
<listitem>
<para>
If generating an RSAMD5/RSASHA1 key, use a large exponent.
</para>

</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 flag is KSK (Key Signing Key) DNSKEY.
</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>
</varlistentry>
<varlistentry>
<term>-h</term>
<listitem>
<para>
Prints a short summary of the options and arguments to
<command>dnssec-keygen</command>.

<listitem>
<para>
Generate KEY records rather than DNSKEY records.
</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>-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">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>

<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>.

.PP
\fBdnssec\-signzone\fR
signs a zone. It generates NSEC and RRSIG records and produces a signed version of the zone. The security status of delegations from the signed zone (that is, whether the child zones are secure or not) is determined by the presence or absence of a
\fIkeyset\fR

.RE
.PP
\-c \fIclass\fR
.RS 4
Specifies the DNS class of the zone.
.RE

\-k \fIkey\fR
.RS 4
Treat specified key as a key signing key ignoring any key flags. This option may be specified multiple times.
.RE
.PP
\-l \fIdomain\fR
.RS 4
Generate a DLV set in addition to the key (DNSKEY) and DS sets. The domain is appended to the name of the records.
.RE

.RS 4
Look for
\fIkeyset\fR

.RE
.PP
\-g
.RS 4
Generate DS records for child zones from keyset files. Existing DS records will be removed.
.RE
.PP
\-s \fIstart\-time\fR
.RS 4
Specify the date and time when the generated RRSIG records become valid. This can be either an absolute or relative time. An absolute start time is indicated by a number in YYYYMMDDHHMMSS notation; 20000530144500 denotes 14:45:00 UTC on May 30th, 2000. A relative start time is indicated by +N, which is N seconds from the current time. If no
\fBstart\-time\fR
is specified, the current time minus 1 hour (to allow for clock skew) is used.
.RE
.PP
\-e \fIend\-time\fR
.RS 4
Specify the date and time when the generated RRSIG records expire. As with
\fBstart\-time\fR, an absolute time is indicated in YYYYMMDDHHMMSS notation. A time relative to the start time is indicated with +N, which is N seconds from the start time. A time relative to the current time is indicated with now+N. If no
\fBend\-time\fR
is specified, 30 days from the start time is used as a default.
.RE
.PP
\-f \fIoutput\-file\fR
.RS 4
The name of the output file containing the signed zone. The default is to append
\fI.signed\fR
to the input filename.
.RE
.PP
\-h
.RS 4
Prints a short summary of the options and arguments to
\fBdnssec\-signzone\fR.
.RE
.PP
\-i \fIinterval\fR
.RS 4
When a previously\-signed zone is passed as input, records may be resigned. The
\fBinterval\fR
option specifies the cycle interval as an offset from the current time (in seconds). If a RRSIG record expires after the cycle interval, it is retained. Otherwise, it is considered to be expiring soon, and it will be replaced.
.sp
The default cycle interval is one quarter of the difference between the signature end and start times. So if neither
\fBend\-time\fR
or
\fBstart\-time\fR
are specified,
\fBdnssec\-signzone\fR
generates signatures that are valid for 30 days, with a cycle interval of 7.5 days. Therefore, if any existing RRSIG records are due to expire in less than 7.5 days, they would be replaced.
.RE
.PP
\-n \fIncpus\fR
.RS 4
Specifies the number of threads to use. By default, one thread is started for each detected CPU.
.RE
.PP
\-o \fIorigin\fR
.RS 4
The zone origin. If not specified, the name of the zone file is assumed to be the origin.
.RE
.PP
\-p
.RS 4
Use pseudo\-random data when signing the zone. This is faster, but less secure, than using real random data. This option may be useful when signing large zones or when the entropy source is limited.
.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

.RS 4
Ignore KSK flag on key when determining what to sign.
.RE
.PP
zonefile
.RS 4
The file containing the zone to be signed.
.RE
.PP
key
.RS 4
Specify which keys should be used to sign the zone. If no keys are specified, then the zone will be examined for DNSKEY records at the zone apex. If these are found and there are matching private keys, in the current directory, then these will be used for signing.
.RE
.SH "EXAMPLE"
.PP
The following command signs the
\fBexample.com\fR
zone with the DSA key generated by
\fBdnssec\-keygen\fR
(Kexample.com.+003+17247). The zone's keys must be in the master file (\fIdb.example.com\fR). This invocation looks for
\fIkeyset\fR
files, in the current directory, so that DS records can be generated from them (\fB\-g\fR).

.PP
In the above example,
\fBdnssec\-signzone\fR
creates the file
\fIdb.example.com.signed\fR. This file should be referenced in a zone statement in a

<a name="id2543877"></a><h2>EXAMPLE</h2>
<p>
The following command signs the <strong class="userinput"><code>example.com</code></strong>
zone with the DSA key generated by <span><strong class="command">dnssec-keygen</strong></span>
(Kexample.com.+003+17247). The zone's keys must be in the master
file (<code class="filename">db.example.com</code>). This invocation looks
for <code class="filename">keyset</code> files, in the current directory,
so that DS records can be generated from them (<span><strong class="command">-g</strong></span>).
</p>
<pre class="programlisting">% dnssec-signzone -g -o example.com db.example.com \
Kexample.com.+003+17247
db.example.com.signed
%</pre>
<p>
In the above example, <span><strong class="command">dnssec-signzone</strong></span> creates
the file <code class="filename">db.example.com.signed</code>. This
file should be referenced in a zone statement in a
<code class="filename">named.conf</code> file.
</p>
<p>
This example re-signs a previously signed zone with default parameters.
The private keys are assumed to be in the current directory.
</p>
<pre class="programlisting">% cp db.example.com.signed db.example.com
% dnssec-signzone -o example.com db.example.com
