THIS ISSUE TEMPLATE IS INTENDED ONLY FOR INTERNAL USE.
|
||||
|
||||
If the bug you are reporting is potentially security-related - for example,
|
||||
if it involves an assertion failure or other crash in `named` that can be
|
||||
triggered repeatedly - then please do *NOT* report it here, but send an
|
||||
email to [security-officer@isc.org](security-officer@isc.org).

|
||||
|
||||
### CVE-specific actions
|
||||
|
||||
- [ ] Assign a CVE identifier
|
||||
- [ ] Determine CVSS score
|
||||
- [ ] Determine the range of BIND versions affected (including the Subscription Edition)
|
||||
- [ ] Determine whether workarounds for the problem exists
|
||||
- [ ] Create a draft of the security advisory and put the information above in there
|
||||
- [ ] Prepare a detailed description of the problem which should include the following by default:
|
||||
- instructions for reproducing the problem (a system test is good enough)
|
||||
- explanation of code flow which triggers the problem (a system test is *not* good enough)
|
||||
- [ ] Prepare a private merge request containing the following items in separate commits:
|
||||
- a test for the issue (may be moved to a separate merge request for deferred merging)
|
||||
- a fix for the issue
|
||||
- documentation updates (`CHANGES`, release notes, anything else applicable)
|
||||
- [ ] Ensure the merge request from the previous step is reviewed by SWENG staff and has no outstanding discussions
|
||||
- [ ] Ensure the documentation changes introduced by the merge request addressing the problem are reviewed by Support and Marketing staff
|
||||
- [ ] Prepare backports of the merge request addressing the problem for all affected (and still maintained) BIND branches (backporting might affect the issue's scope and/or description)
|
||||
- [ ] Prepare a standalone patch for the last stable release of each affected (and still maintained) BIND branch
|
||||
|
||||
### Release-specific actions
|
||||
|
||||
- [ ] Create/update the private issue containing links to fixes & reproducers for all CVEs fixed in a given release cycle
|
||||
- [ ] Reserve a block of `CHANGES` placeholders once the complete set of vulnerabilities fixed in a given release cycle is determined
|
||||
- [ ] Ensure the merge requests containing CVE fixes are merged into `security-*` branches in CVE identifier order
|
||||
|
||||
### Post-disclosure actions
|
||||
|
||||
- [ ] Merge a regression test reproducing the bug into all affected (and still maintained) BIND branches

### Functional enhancements from prior major releases of BIND 9
|
||||
|
||||
#### BIND 9.16
|
||||
|
||||
BIND 9.16 (a stable branch based on the 9.15 development branch)
|
||||
includes a number of changes from BIND 9.14 and earlier releases.
|
||||
New features include:
|
||||
|
||||
* New `dnssec-policy` statement to configure a key and signing policy
|
||||
for zones, enabling automatic key regeneration and rollover.
|
||||
* New network manager based on `libuv`.
|
||||
* Added support for the new GeoIP2 geolocation API, `libmaxminddb`.
|
||||
* Improved DNSSEC trust anchor configuration using the `trust-anchors`
|
||||
statement, permitting configuration of trust anchors in DS as well as
|
||||
DNSKEY format.
|
||||
* YAML output for `dig`, `mdig`, and `delv`.
|
||||
|
||||
#### BIND 9.14
|
||||
|
||||
BIND 9.14 (a stable branch based on the 9.13 development branch)
|
||||
includes a number of changes from BIND 9.12 and earlier releases.
|
||||
New features include:
|
||||
|
||||
* A new "plugin" mechanism has been added to allow query functionality
|
||||
to be extended using dynamically loadable libraries. The "filter-aaaa"
|
||||
feature has been removed from named and is now implemented as a plugin.
|
||||
* Socket and task code has been refactored to improve performance.
|
||||
* QNAME minimization, as described in RFC 7816, is now supported.
|
||||
* "Root key sentinel" support, enabling validating resolvers to indicate
|
||||
via a special query which trust anchors are configured for the root zone.
|
||||
* Secondary zones can now be configured as "mirror" zones; their contents
|
||||
are transferred in as with traditional slave zones, but are subject to
|
||||
DNSSEC validation and are not treated as authoritative data when
|
||||
answering. This makes it easier to configure a local copy of the root
|
||||
zone as described in RFC 7706.
|
||||
* The "validate-except" option allows configuration of domains below which
|
||||
DNSSEC validation should not be performed.
|
||||
* The default value of "dnssec-validation" is now "auto".
|
||||
* IDNA2008 is now supported when linking with `libidn2`.
|
||||
* "named -V" now outputs the default paths for files used by named
|
||||
and other tools.
|
||||
|
||||
In addition, workarounds that were formerly in place to enable resolution
|
||||
of domains whose authoritative servers did not respond to EDNS queries
|
||||
have been removed. See [https://dnsflagday.net](https://dnsflagday.net)
|
||||
for more details.
|
||||
|
||||
Cryptographic support has been modernized. BIND now uses the
|
||||
best available pseudo-random number generator for the platform on which
|
||||
it's built. Very old versions of OpenSSL are no longer supported.
|
||||
Cryptography is now mandatory: building BIND without DNSSEC is no
|
||||
longer supported.
|
||||
|
||||
Special code to support certain legacy operating systems has also
|
||||
been removed; see the file [PLATFORMS.md](PLATFORMS.md) for details
|
||||
of supported platforms. In addition to OpenSSL, BIND now requires
|
||||
support for IPv6, threads, and standard atomic operations provided
|
||||
by the C compiler.
|
||||
|
||||
#### BIND 9.12
|
||||
|
||||
BIND 9.12 includes a number of changes from BIND 9.11 and earlier releases.
|
||||
New features include:
|
||||
|
||||
* `named` and related libraries have been substantially refactored for
|
||||
improved query performance -- particularly on delegation heavy zones --
|
||||
and for improved readability, maintainability, and testability.
|
||||
* Code implementing the name server query processing logic has been moved
|
||||
into a new `libns` library, for easier testing and use in tools other
|
||||
than `named`.
|
||||
* Cached, validated NSEC and other records can now be used to synthesize
|
||||
NXDOMAIN responses.
|
||||
* The DNS Response Policy Service API (DNSRPS) is now supported.
|
||||
* Setting `'max-journal-size default'` now limits the size of journal files
|
||||
to twice the size of the zone.
|
||||
* `dnstap-read -x` prints a hex dump of the wire format of each logged
|
||||
DNS message.
|
||||
* `dnstap` output files can now be configured to roll automatically when
|
||||
reaching a given size.
|
||||
* Log file timestamps can now also be formatted in ISO 8601 (local) or ISO
|
||||
8601 (UTC) formats.
|
||||
* Logging channels and `dnstap` output files can now be configured to use a
|
||||
timestamp as the suffix when rolling to a new file.
|
||||
* `'named-checkconf -l'` lists zones found in `named.conf`.
|
||||
* Added support for the EDNS Padding and Keepalive options.
|
||||
* 'new-zones-directory' option sets the location where the configuration
|
||||
data for zones added by rndc addzone is stored.
|
||||
* The default key algorithm in `rndc-confgen` is now hmac-sha256.
|
||||
* `filter-aaaa-on-v4` and `filter-aaaa-on-v6` options are now available
|
||||
by default without a configure option.
|
||||
* The obsolete `isc-hmac-fixup` command has been removed.
|
||||
|
||||
#### BIND 9.11
|
||||
|
||||
BIND 9.11.0 includes a number of changes from BIND 9.10 and earlier
|
||||
releases. New features include:
|
||||
|
||||
- Added support for Catalog Zones, a new method for provisioning servers: a
|
||||
list of zones to be served is stored in a DNS zone, along with their
|
||||
configuration parameters. Changes to the catalog zone are propagated to
|
||||
slaves via normal AXFR/IXFR, whereupon the zones that are listed in it
|
||||
are automatically added, deleted or reconfigured.
|
||||
- Added support for "dnstap", a fast and flexible method of capturing and
|
||||
logging DNS traffic.
|
||||
- Added support for "dyndb", a new API for loading zone data from an
|
||||
external database, developed by Red Hat for the FreeIPA project.
|
||||
- "fetchlimit" quotas are now compiled in by default. These are for the
|
||||
use of recursive resolvers that are are under high query load for domains
|
||||
whose authoritative servers are nonresponsive or are experiencing a
|
||||
denial of service attack:
|
||||
- "fetches-per-server" limits the number of simultaneous queries that
|
||||
can be sent to any single authoritative server. The configured value
|
||||
is a starting point; it is automatically adjusted downward if the
|
||||
server is partially or completely non-responsive. The algorithm used
|
||||
to adjust the quota can be configured via the "fetch-quota-params"
|
||||
option.
|
||||
- "fetches-per-zone" limits the number of simultaneous queries that can
|
||||
be sent for names within a single domain. (Note: Unlike
|
||||
"fetches-per-server", this value is not self-tuning.)
|
||||
- New stats counters have been added to count queries spilled due to
|
||||
these quotas.
|
||||
- Added a new "dnssec-keymgr" key mainenance utility, which can generate or
|
||||
update keys as needed to ensure that a zone's keys match a defined DNSSEC
|
||||
policy.
|
||||
- The experimental "SIT" feature in BIND 9.10 has been renamed "COOKIE" and
|
||||
is no longer optional. EDNS COOKIE is a mechanism enabling clients to
|
||||
detect off-path spoofed responses, and servers to detect spoofed-source
|
||||
queries. Clients that identify themselves using COOKIE options are not
|
||||
subject to response rate limiting (RRL) and can receive larger UDP
|
||||
responses.
|
||||
- SERVFAIL responses can now be cached for a limited time (defaulting to 1
|
||||
second, with an upper limit of 30). This can reduce the frequency of
|
||||
retries when a query is persistently failing.
|
||||
- Added an "nsip-wait-recurse" switch to RPZ. This causes NSIP rules to be
|
||||
skipped if a name server IP address isn't in the cache yet; the address
|
||||
will be looked up and the rule will be applied on future queries.
|
||||
- Added a Python RNDC module. This allows multiple commands to sent over a
|
||||
persistent RNDC channel, which saves time.
|
||||
- The "controls" block in named.conf can now grant read-only "rndc" access
|
||||
to specified clients or keys. Read-only clients could, for example, check
|
||||
"rndc status" but could not reconfigure or shut down the server.
|
||||
- "rndc" commands can now return arbitrarily large amounts of text to the
|
||||
caller.
|
||||
- The zone serial number of a dynamically updatable zone can now be set via
|
||||
"rndc signing -serial <number> <zonename>". This allows inline-signing
|
||||
zones to be set to a specific serial number.
|
||||
- The new "rndc nta" command can be used to set a Negative Trust Anchor
|
||||
(NTA), disabling DNSSEC validation for a specific domain; this can be
|
||||
used when responses from a domain are known to be failing validation due
|
||||
to administrative error rather than because of a spoofing attack.
|
||||
Negative trust anchors are strictly temporary; by default they expire
|
||||
after one hour, but can be configured to last up to one week.
|
||||
- "rndc delzone" can now be used on zones that were not originally created
|
||||
by "rndc addzone".
|
||||
- "rndc modzone" reconfigures a single zone, without requiring the entire
|
||||
server to be reconfigured.
|
||||
- "rndc showzone" displays the current configuration of a zone.
|
||||
- "rndc managed-keys" can be used to check the status of RFC 5011 managed
|
||||
trust anchors, or to force trust anchors to be refreshed.
|
||||
- "max-cache-size" can now be set to a percentage of available memory. The
|
||||
default is 90%.
|
||||
- Update forwarding performance has been improved by allowing a single TCP
|
||||
connection to be shared by multiple updates.
|
||||
- The EDNS Client Subnet (ECS) option is now supported for authoritative
|
||||
servers; if a query contains an ECS option then ACLs containing "geoip"
|
||||
or "ecs" elements can match against the the address encoded in the
|
||||
option. This can be used to select a view for a query, so that different
|
||||
answers can be provided depending on the client network.
|
||||
- The EDNS EXPIRE option has been implemented on the client side, allowing
|
||||
a slave server to set the expiration timer correctly when transferring
|
||||
zone data from another slave server.
|
||||
- The key generation and manipulation tools (dnssec-keygen, dnssec-settime,
|
||||
dnssec-importkey, dnssec-keyfromlabel) now take "-Psync" and "-Dsync"
|
||||
options to set the publication and deletion times of CDS and CDNSKEY
|
||||
parent-synchronization records. Both named and dnssec-signzone can now
|
||||
publish and remove these records at the scheduled times.
|
||||
- A new "minimal-any" option reduces the size of UDP responses for query
|
||||
type ANY by returning a single arbitrarily selected RRset instead of all
|
||||
RRsets.
|
||||
- A new "masterfile-style" zone option controls the formatting of text zone
|
||||
files: When set to "full", a zone file is dumped in
|
||||
single-line-per-record format.
|
||||
- "serial-update-method" can now be set to "date". On update, the serial
|
||||
number will be set to the current date in YYYYMMDDNN format.
|
||||
- "dnssec-signzone -N date" sets the serial number to YYYYMMDDNN.
|
||||
- "named -L <filename>" causes named to send log messages to the specified
|
||||
file by default instead of to the system log.
|
||||
- "dig +ttlunits" prints TTL values with time-unit suffixes: w, d, h, m, s
|
||||
for weeks, days, hours, minutes, and seconds.
|
||||
- "dig +unknownformat" prints dig output in RFC 3597 "unknown record"
|
||||
presentation format.
|
||||
- "dig +ednsopt" allows dig to set arbitrary EDNS options on requests.
|
||||
- "dig +ednsflags" allows dig to set yet-to-be-defined EDNS flags on
|
||||
requests.
|
||||
- "mdig" is an alternate version of dig which sends multiple pipelined TCP
|
||||
queries to a server. Instead of waiting for a response after sending a
|
||||
query, it sends all queries immediately and displays responses in the
|
||||
order received.
|
||||
- "serial-query-rate" no longer controls NOTIFY messages. These are
|
||||
separately controlled by "notify-rate" and "startup-notify-rate".
|
||||
- "nsupdate" now performs "check-names" processing by default on records to
|
||||
be added. This can be disabled with "check-names no".
|
||||
- The statistics channel now supports DEFLATE compression, reducing the
|
||||
size of the data sent over the network when querying statistics.
|
||||
- New counters have been added to the statistics channel to track the sizes
|
||||
of incoming queries and outgoing responses in histogram buckets, as
|
||||
specified in RSSAC002.
|
||||
- A new NXDOMAIN redirect method (option "nxdomain-redirect") has been
|
||||
added, allowing redirection to a specified DNS namespace instead of a
|
||||
single redirect zone.
|
||||
- When starting up, named now ensures that no other named process is
|
||||
already running.
|
||||
- Files created by named to store information, including "mkeys" and "nzf"
|
||||
files, are now named after their corresponding views unless the view name
|
||||
contains characters incompatible with use as a filename. Old style
|
||||
filenames (based on the hash of the view name) will still work.
|
||||
|
||||
#### BIND 9.10.0
|
||||
|
||||
BIND 9.10.0 includes a number of changes from BIND 9.9 and earlier
|
||||
releases. New features include:
|
||||
|
||||
- DNS Response-rate limiting (DNS RRL), which blunts the
|
||||
impact of reflection and amplification attacks, is always
|
||||
compiled in and no longer requires a compile-time option
|
||||
to enable it.
|
||||
- An experimental "Source Identity Token" (SIT) EDNS option
|
||||
is now available. Similar to DNS Cookies as invented by
|
||||
Donald Eastlake 3rd, these are designed to enable clients
|
||||
to detect off-path spoofed responses, and to enable servers
|
||||
to detect spoofed-source queries. Servers can be configured
|
||||
to send smaller responses to clients that have not identified
|
||||
themselves using a SIT option, reducing the effectiveness of
|
||||
amplification attacks. RRL processing has also been updated;
|
||||
clients proven to be legitimate via SIT are not subject to
|
||||
rate limiting. Use "configure --enable-sit" to enable this
|
||||
feature in BIND.
|
||||
- A new zone file format, "map", stores zone data in a
|
||||
format that can be mapped directly into memory, allowing
|
||||
significantly faster zone loading.
|
||||
- "delv" (domain entity lookup and validation) is a new tool
|
||||
with dig-like semantics for looking up DNS data and performing
|
||||
internal DNSSEC validation. This allows easy validation in
|
||||
environments where the resolver may not be trustworthy, and
|
||||
assists with troubleshooting of DNSSEC problems. (NOTE:
|
||||
In previous development releases of BIND 9.10, this utility
|
||||
was called "delve". The spelling has been changed to avoid
|
||||
confusion with the "delve" utility included with the Xapian
|
||||
search engine.)
|
||||
- Improved EDNS(0) processing for better resolver performance
|
||||
and reliability over slow or lossy connections.
|
||||
- A new "configure --with-tuning=large" option tunes certain
|
||||
compiled-in constants and default settings to values better
|
||||
suited to large servers with abundant memory. This can
|
||||
improve performance on such servers, but will consume more
|
||||
memory and may degrade performance on smaller systems.
|
||||
- Substantial improvement in response-policy zone (RPZ)
|
||||
performance. Up to 32 response-policy zones can be
|
||||
configured with minimal performance loss.
|
||||
- To improve recursive resolver performance, cache records
|
||||
which are still being requested by clients can now be
|
||||
automatically refreshed from the authoritative server
|
||||
before they expire, reducing or eliminating the time
|
||||
window in which no answer is available in the cache.
|
||||
- New "rpz-client-ip" triggers and drop policies allowing
|
||||
response policies based on the IP address of the client.
|
||||
- ACLs can now be specified based on geographic location
|
||||
using the MaxMind GeoIP databases. Use "configure
|
||||
--with-geoip" to enable.
|
||||
- Zone data can now be shared between views, allowing
|
||||
multiple views to serve the same zones authoritatively
|
||||
without storing multiple copies in memory.
|
||||
- New XML schema (version 3) for the statistics channel
|
||||
includes many new statistics and uses a flattened XML tree
|
||||
for faster parsing. The older schema is now deprecated.
|
||||
- A new stylesheet, based on the Google Charts API, displays
|
||||
XML statistics in charts and graphs on javascript-enabled
|
||||
browsers.
|
||||
- The statistics channel can now provide data in JSON
|
||||
format as well as XML.
|
||||
- New stats counters track TCP and UDP queries received
|
||||
per zone, and EDNS options received in total.
|
||||
- The internal and export versions of the BIND libraries
|
||||
(libisc, libdns, etc) have been unified so that external
|
||||
library clients can use the same libraries as BIND itself.
|
||||
- A new compile-time option, "configure --enable-native-pkcs11",
|
||||
allows BIND 9 cryptography functions to use the PKCS#11 API
|
||||
natively, so that BIND can drive a cryptographic hardware
|
||||
service module (HSM) directly instead of using a modified
|
||||
OpenSSL as an intermediary. (Note: This feature requires an
|
||||
HSM to have a full implementation of the PKCS#11 API; many
|
||||
current HSMs only have partial implementations. The new
|
||||
"pkcs11-tokens" command can be used to check API completeness.
|
||||
Native PKCS#11 is known to work with the Thales nShield HSM
|
||||
and with SoftHSM version 2 from the Open DNSSEC project.)
|
||||
- The new "max-zone-ttl" option enforces maximum TTLs for
|
||||
zones. This can simplify the process of rolling DNSSEC keys
|
||||
by guaranteeing that cached signatures will have expired
|
||||
within the specified amount of time.
|
||||
- "dig +subnet" sends an EDNS CLIENT-SUBNET option when
|
||||
querying.
|
||||
- "dig +expire" sends an EDNS EXPIRE option when querying.
|
||||
When this option is sent with an SOA query to a server
|
||||
that supports it, it will report the expiry time of
|
||||
a slave zone.
|
||||
- New "dnssec-coverage" tool to check DNSSEC key coverage
|
||||
for a zone and report if a lapse in signing coverage has
|
||||
been inadvertently scheduled.
|
||||
- Signing algorithm flexibility and other improvements
|
||||
for the "rndc" control channel.
|
||||
- "named-checkzone" and "named-compilezone" can now read
|
||||
journal files, allowing them to process dynamic zones.
|
||||
- Multiple DLZ databases can now be configured. Individual
|
||||
zones can be configured to be served from a specific DLZ
|
||||
database. DLZ databases now serve zones of type "master"
|
||||
and "redirect".
|
||||
- "rndc zonestatus" reports information about a specified zone.
|
||||
- "named" now listens on IPv6 as well as IPv4 interfaces
|
||||
by default.
|
||||
- "named" now preserves the capitalization of names
|
||||
when responding to queries: for instance, a query for
|
||||
"example.com" may be answered with "example.COM" if the
|
||||
name was configured that way in the zone file. Some
|
||||
clients have a bug causing them to depend on the older
|
||||
behavior, in which the case of the answer always matched
|
||||
the case of the query, rather than the case of the name
|
||||
configured in the DNS. Such clients can now be specified
|
||||
in the new "no-case-compress" ACL; this will restore the
|
||||
older behavior of "named" for those clients only.
|
||||
- new "dnssec-importkey" command allows the use of offline
|
||||
DNSSEC keys with automatic DNSKEY management.
|
||||
- New "named-rrchecker" tool to verify the syntactic
|
||||
correctness of individual resource records.
|
||||
- When re-signing a zone, the new "dnssec-signzone -Q" option
|
||||
drops signatures from keys that are still published but are
|
||||
no longer active.
|
||||
- "named-checkconf -px" will print the contents of configuration
|
||||
files with the shared secrets obscured, making it easier to
|
||||
share configuration (e.g. when submitting a bug report)
|
||||
without revealing private information.
|
||||
- "rndc scan" causes named to re-scan network interfaces for
|
||||
changes in local addresses.
|
||||
- On operating systems with support for routing sockets,
|
||||
network interfaces are re-scanned automatically whenever
|
||||
they change.
|
||||
- "tsig-keygen" is now available as an alternate command
|
||||
name to use for "ddns-confgen".
|
||||
|
||||
#### BIND 9.9.0
|
||||
|
||||
BIND 9.9.0 includes a number of changes from BIND 9.8 and earlier
|
||||
releases. New features include:
|
||||
|
||||
- Inline signing, allowing automatic DNSSEC signing of
|
||||
master zones without modification of the zonefile, or
|
||||
"bump in the wire" signing in slaves.
|
||||
- NXDOMAIN redirection.
|
||||
- New 'rndc flushtree' command clears all data under a given
|
||||
name from the DNS cache.
|
||||
- New 'rndc sync' command dumps pending changes in a dynamic
|
||||
zone to disk without a freeze/thaw cycle.
|
||||
- New 'rndc signing' command displays or clears signing status
|
||||
records in 'auto-dnssec' zones.
|
||||
- NSEC3 parameters for 'auto-dnssec' zones can now be set prior
|
||||
to signing, eliminating the need to initially sign with NSEC.
|
||||
- Startup time improvements on large authoritative servers.
|
||||
- Slave zones are now saved in raw format by default.
|
||||
- Several improvements to response policy zones (RPZ).
|
||||
- Improved hardware scalability by using multiple threads
|
||||
to listen for queries and using finer-grained client locking
|
||||
- The 'also-notify' option now takes the same syntax as
|
||||
'masters', so it can used named masterlists and TSIG keys.
|
||||
- 'dnssec-signzone -D' writes an output file containing only DNSSEC
|
||||
data, which can be included by the primary zone file.
|
||||
- 'dnssec-signzone -R' forces removal of signatures that are
|
||||
not expired but were created by a key which no longer exists.
|
||||
- 'dnssec-signzone -X' allows a separate expiration date to
|
||||
be specified for DNSKEY signatures from other signatures.
|
||||
- New '-L' option to dnssec-keygen, dnssec-settime, and
|
||||
dnssec-keyfromlabel sets the default TTL for the key.
|
||||
- dnssec-dsfromkey now supports reading from standard input,
|
||||
to make it easier to convert DNSKEY to DS.
|
||||
- RFC 1918 reverse zones have been added to the empty-zones
|
||||
table per RFC 6303.
|
||||
- Dynamic updates can now optionally set the zone's SOA serial
|
||||
number to the current UNIX time.
|
||||
- DLZ modules can now retrieve the source IP address of
|
||||
the querying client.
|
||||
- 'request-ixfr' option can now be set at the per-zone level.
|
||||
- 'dig +rrcomments' turns on comments about DNSKEY records,
|
||||
indicating their key ID, algorithm and function
|
||||
- Simplified nsupdate syntax and added readline support
|
||||
|
||||
#### BIND 9.8.0
|
||||
|
||||
BIND 9.8.0 includes a number of changes from BIND 9.7 and earlier
|
||||
releases. New features include:
|
||||
|
||||
- Built-in trust anchor for the root zone, which can be
|
||||
switched on via "dnssec-validation auto;"
|
||||
- Support for DNS64.
|
||||
- Support for response policy zones (RPZ).
|
||||
- Support for writable DLZ zones.
|
||||
- Improved ease of configuration of GSS/TSIG for
|
||||
interoperability with Active Directory
|
||||
- Support for GOST signing algorithm for DNSSEC.
|
||||
- Removed RTT Banding from server selection algorithm.
|
||||
- New "static-stub" zone type.
|
||||
- Allow configuration of resolver timeouts via
|
||||
"resolver-query-timeout" option.
|
||||
- The DLZ "dlopen" driver is now built by default.
|
||||
- Added a new include file with function typedefs
|
||||
for the DLZ "dlopen" driver.
|
||||
- Made "--with-gssapi" default.
|
||||
- More verbose error reporting from DLZ LDAP.
|
||||
|
||||
#### BIND 9.7.0
|
||||
|
||||
BIND 9.7.0 includes a number of changes from BIND 9.6 and earlier
|
||||
releases. Most are intended to simplify DNSSEC configuration.
|
||||
New features include:
|
||||
|
||||
- Fully automatic signing of zones by "named".
|
||||
- Simplified configuration of DNSSEC Lookaside Validation (DLV).
|
||||
- Simplified configuration of Dynamic DNS, using the "ddns-confgen"
|
||||
command line tool or the "local" update-policy option. (As a side
|
||||
effect, this also makes it easier to configure automatic zone
|
||||
re-signing.)
|
||||
- New named option "attach-cache" that allows multiple views to
|
||||
share a single cache.
|
||||
- DNS rebinding attack prevention.
|
||||
- New default values for dnssec-keygen parameters.
|
||||
- Support for RFC 5011 automated trust anchor maintenance
|
||||
- Smart signing: simplified tools for zone signing and key
|
||||
maintenance.
|
||||
- The "statistics-channels" option is now available on Windows.
|
||||
- A new DNSSEC-aware libdns API for use by non-BIND9 applications
|
||||
- On some platforms, named and other binaries can now print out
|
||||
a stack backtrace on assertion failure, to aid in debugging.
|
||||
- A "tools only" installation mode on Windows, which only installs
|
||||
dig, host, nslookup and nsupdate.
|
||||
- Improved PKCS#11 support, including Keyper support and explicit
|
||||
OpenSSL engine selection.
|
||||
|
||||
#### BIND 9.6.0
|
||||
|
||||
- Full NSEC3 support
|
||||
- Automatic zone re-signing
|
||||
- New update-policy methods tcp-self and 6to4-self
|
||||
- The BIND 8 resolver library, libbind, has been removed from the BIND 9
|
||||
distribution and is now available as a separate download.
|
||||
- Change the default pid file location from /var/run to
|
||||
/var/run/{named,lwresd} for improved chroot/setuid support.
|
||||
|
||||
#### BIND 9.5.0
|
||||
|
||||
- GSS-TSIG support (RFC 3645).
|
||||
- DHCID support.
|
||||
- Experimental http server and statistics support for named via xml.
|
||||
- More detailed statistics counters including those supported in BIND 8.
|
||||
- Faster ACL processing.
|
||||
- Use Doxygen to generate internal documentation.
|
||||
- Efficient LRU cache-cleaning mechanism.
|
||||
- NSID support.
|
||||
|
||||
BIND 9.4.0
|
||||
|
||||
- Implemented "additional section caching (or acache)", an internal cache
|
||||
framework for additional section content to improve response performance.
|
||||
Several configuration options were provided to control the behavior.
|
||||
- New notify type 'master-only'. Enable notify for master zones only.
|
||||
- Accept 'notify-source' style syntax for query-source.
|
||||
- rndc now allows addresses to be set in the server clauses.
|
||||
- New option "allow-query-cache". This lets "allow-query" be used to
|
||||
specify the default zone access level rather than having to have every
|
||||
zone override the global value. "allow-query-cache" can be set at both
|
||||
the options and view levels. If "allow-query-cache" is not set then
|
||||
"allow-recursion" is used if set, otherwise "allow-query" is used if set
|
||||
unless "recursion no;" is set in which case "none;" is used, otherwise
|
||||
the default (localhost; localnets;) is used.
|
||||
- rndc: the source address can now be specified.
|
||||
- ixfr-from-differences now takes master and slave in addition to yes and
|
||||
no at the options and view levels.
|
||||
- Allow the journal's name to be changed via named.conf.
|
||||
- 'rndc notify zone [class [view]]' resend the NOTIFY messages for the
|
||||
specified zone.
|
||||
- 'dig +trace' now randomly selects the next servers to try. Report if
|
||||
there is a bad delegation.
|
||||
- Improve check-names error messages.
|
||||
- Make public the function to read a key file, dst_key_read_public().
|
||||
- dig now returns the byte count for axfr/ixfr.
|
||||
- allow-update is now settable at the options / view level.
|
||||
- named-checkconf now checks the logging configuration.
|
||||
- host now can turn on memory debugging flags with '-m'.
|
||||
- Don't send notify messages to self.
|
||||
- Perform sanity checks on NS records which refer to 'in zone' names.
|
||||
- New zone option "notify-delay". Specify a minimum delay between sets of
|
||||
NOTIFY messages.
|
||||
- Extend adjusting TTL warning messages.
|
||||
- Named and named-checkzone can now both check for non-terminal wildcard
|
||||
records.
|
||||
- "rndc freeze/thaw" now freezes/thaws all zones.
|
||||
- named-checkconf now check acls to verify that they only refer to existing
|
||||
acls.
|
||||
- The server syntax has been extended to support a range of servers.
|
||||
- Report differences between hints and real NS rrset and associated address
|
||||
records.
|
||||
- Preserve the case of domain names in rdata during zone transfers.
|
||||
- Restructured the data locking framework using architecture dependent
|
||||
atomic operations (when available), improving response performance on
|
||||
multi-processor machines significantly. x86, x86_64, alpha, powerpc, and
|
||||
mips are currently supported.
|
||||
- UNIX domain controls are now supported.
|
||||
- Add support for additional zone file formats for improving loading
|
||||
performance. The masterfile-format option in named.conf can be used to
|
||||
specify a non-default format. A separate command named-compilezone was
|
||||
provided to generate zone files in the new format. Additionally, the -I
|
||||
and -O options for dnssec-signzone specify the input and output formats.
|
||||
- dnssec-signzone can now randomize signature end times (dnssec-signzone -j
|
||||
jitter).
|
||||
- Add support for CH A record.
|
||||
- Add additional zone data constancy checks. named-checkzone has extended
|
||||
checking of NS, MX and SRV record and the hosts they reference. named
|
||||
has extended post zone load checks. New zone options: check-mx and
|
||||
integrity-check.
|
||||
- edns-udp-size can now be overridden on a per server basis.
|
||||
- dig can now specify the EDNS version when making a query.
|
||||
- Added framework for handling multiple EDNS versions.
|
||||
- Additional memory debugging support to track size and mctx arguments.
|
||||
- Detect duplicates of UDP queries we are recursing on and drop them. New
|
||||
stats category "duplicates".
|
||||
- "USE INTERNAL MALLOC" is now runtime selectable.
|
||||
- The lame cache is now done on a <qname,qclass,qtype> basis as some
|
||||
servers only appear to be lame for certain query types.
|
||||
- Limit the number of recursive clients that can be waiting for a single
|
||||
query (<qname,qtype,qclass>) to resolve. New options clients-per-query
|
||||
and max-clients-per-query.
|
||||
- dig: report the number of extra bytes still left in the packet after
|
||||
processing all the records.
|
||||
- Support for IPSECKEY rdata type.
|
||||
- Raise the UDP receive buffer size to 32k if it is less than 32k.
|
||||
- x86 and x86_64 now have separate atomic locking implementations.
|
||||
- named-checkconf now validates update-policy entries.
|
||||
- Attempt to make the amount of work performed in a iteration self tuning.
|
||||
The covers nodes clean from the cache per iteration, nodes written to
|
||||
disk when rewriting a master file and nodes destroyed per iteration when
|
||||
destroying a zone or a cache.
|
||||
- ISC string copy API.
|
||||
- Automatic empty zone creation for D.F.IP6.ARPA and friends. Note: RFC
|
||||
1918 zones are not yet covered by this but are likely to be in a future
|
||||
release.
|
||||
- New options: empty-server, empty-contact, empty-zones-enable and
|
||||
disable-empty-zone.
|
||||
- dig now has a '-q queryname' and '+showsearch' options.
|
||||
- host/nslookup now continue (default)/fail on SERVFAIL.
|
||||
- dig now warns if 'RA' is not set in the answer when 'RD' was set in the
|
||||
query. host/nslookup skip servers that fail to set 'RA' when 'RD' is set
|
||||
unless a server is explicitly set.
|
||||
- Integrate contributed DLZ code into named.
|
||||
- Integrate contributed IDN code from JPNIC.
|
||||
- libbind: corresponds to that from BIND 8.4.7.
|
||||
|
||||
#### BIND 9.3.0
|
||||
|
||||
- DNSSEC is now DS based (RFC 3658).
|
||||
- DNSSEC lookaside validation.
|
||||
- check-names is now implemented.
|
||||
- rrset-order is 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.
|
||||
- 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
|
||||
|
||||
- The size of the cache can now be limited using the "max-cache-size"
|
||||
option.
|
||||
- The server can now automatically convert RFC1886-style recursive lookup
|
||||
requests into RFC2874-style lookups, when enabled using the new option
|
||||
"allow-v6-synthesis". This allows stub resolvers that support AAAA
|
||||
records but not A6 record chains or binary labels to perform lookups in
|
||||
domains that make use of these IPv6 DNS features.
|
||||
- Performance has been improved.
|
||||
- The man pages now use the more portable "man" macros rather than the
|
||||
"mandoc" macros, and are installed by "make install".
|
||||
- The named.conf parser has been completely rewritten. It now supports
|
||||
"include" directives in more places such as inside "view" statements, and
|
||||
it no longer has any reserved words.
|
||||
- The "rndc status" command is now implemented.
|
||||
- rndc can now be configured automatically.
|
||||
- A BIND 8 compatible stub resolver library is now included in lib/bind.
|
||||
- OpenSSL has been removed from the distribution. This means that to use
|
||||
DNSSEC, OpenSSL must be installed and the --with-openssl option must be
|
||||
supplied to configure. This does not apply to the use of TSIG, which
|
||||
does not require OpenSSL.
|
||||
- The source distribution now builds on Windows. See
|
||||
win32utils/readme1.txt and win32utils/win32-build.txt for details.
|
||||
- This distribution also includes a new lightweight stub resolver library
|
||||
and associated resolver daemon that fully support forward and reverse
|
||||
lookups of both IPv4 and IPv6 addresses. This library is considered
|
||||
experimental and is not a complete replacement for the BIND 8 resolver
|
||||
library. Applications that use the BIND 8 `res_*` functions to perform
|
||||
DNS lookups or dynamic updates still need to be linked against the BIND 8
|
||||
libraries. For DNS lookups, they can also use the new "getrrsetbyname()"
|
||||
API.
|
||||
- BIND 9.2 is capable of acting as an authoritative server for DNSSEC
|
||||
secured zones. This functionality is believed to be stable and complete
|
||||
except for lacking support for verifications involving wildcard records
|
||||
in secure zones.
|
||||
- When acting as a caching server, BIND 9.2 can be configured to perform
|
||||
DNSSEC secure resolution on behalf of its clients. This part of the
|
||||
DNSSEC implementation is still considered experimental. For detailed
|
||||
information about the state of the DNSSEC implementation, see the file
|
||||
doc/misc/dnssec.

### <a name="build"/> Building BIND 9
|
||||
### <a name="features"/> BIND 9.17 features
|
||||
|
||||
At a minimum, BIND requires a Unix or Linux system with an ANSI C compiler,
|
||||
basic POSIX support, and a 64-bit integer type. BIND also requires the
|
||||
`libuv` asynchronous I/O library, the `nghttp2` HTTP/2 library, the
|
||||
`jemalloc` memory allocation library, and the OpenSSL cryptography
|
||||
library. On Linux, BIND requires the `libcap` library to set process
|
||||
privileges, though this requirement can be overridden by disabling
|
||||
capability support at compile time. See [Compile-time options](#opts)
|
||||
below for details on other libraries that may be required to support
|
||||
BIND 9.17 is the newest development branch of BIND 9. It includes a
|
||||
number of changes from BIND 9.16 and earlier releases. New features include:
|
||||
|
||||
* New option "max-ixfr-ratio" to limit the size of outgoing IXFR responses
|
||||
before falling back to full zone transfers.
|
||||
* "rndc nta -d" and "rndc secroots" now include "validate-except" entries
|
||||
when listing negative trust anchors.

### <a name="build"/> Building BIND
|
||||
|
||||
Minimally, BIND requires a UNIX or Linux system with an ANSI C compiler,
|
||||
basic POSIX support, and a 64-bit integer type. BIND also requires the
|
||||
`libuv` asynchronous I/O library, and a cryptography provider library
|
||||
such as OpenSSL or a hardware service module supporting PKCS#11. On
|
||||
Linux, BIND requires the `libcap` library to set process privileges,
|
||||
though this requirement can be overridden by disabling capability
|
||||
support at compile time. See [Compile-time options](#opts) below
|
||||
for details on other libraries that may be required to support

optional features.

Synopsis
|
||||
~~~~~~~~
|
||||
|
||||
:program:`named-checkconf` [**-chjlvz**] [**-p** [**-x** ]] [**-t** directory] {filename}
|
||||
|
||||
Description
|
||||
~~~~~~~~~~~
|
||||
|
||||
``named-checkconf`` checks the syntax, but not the semantics, of a
|
||||
``named`` configuration file. The file, along with all files included by it, is parsed and checked for syntax
|
||||
errors. If no file is specified,
|
||||
``/etc/named.conf`` is read by default.
|
||||
|
||||
Note: files that ``named`` reads in separate parser contexts, such as
|
||||
``rndc.key`` and ``bind.keys``, are not automatically read by
|
||||
``named-checkconf``. Configuration errors in these files may cause
|
||||
``named`` to fail to run, even if ``named-checkconf`` was successful.
|
||||
However, ``named-checkconf`` can be run on these files explicitly.
|
||||
|
||||
Options
|
||||
~~~~~~~
|
||||
|
||||
``-h``
|
||||
This option prints the usage summary and exits.
|
||||
|
||||
``-j``
|
||||
When loading a zonefile, this option instructs ``named`` to read the journal if it exists.
|
||||
|
||||
``-l``
|
||||
This option lists all the configured zones. Each line of output contains the zone
|
||||
name, class (e.g. IN), view, and type (e.g. primary or secondary).
|
||||
|
||||
``-c``
|
||||
This option specifies that only the "core" configuration should be checked. This suppresses the loading of
|
||||
plugin modules, and causes all parameters to ``plugin`` statements to
|
||||
be ignored.
|
||||
|
||||
``-i``
|
||||
This option ignores warnings on deprecated options.
|
||||
|
||||
``-p``
|
||||
This option prints out the ``named.conf`` and included files in canonical form if
|
||||
no errors were detected. See also the ``-x`` option.
|
||||
|
||||
``-t directory``
|
||||
This option instructs ``named`` to chroot to ``directory``, so that ``include`` directives in the
|
||||
configuration file are processed as if run by a similarly chrooted
|
||||
``named``.
|
||||
|
||||
``-v``
|
||||
This option prints the version of the ``named-checkconf`` program and exits.
|
||||
|
||||
``-x``
|
||||
When printing the configuration files in canonical form, this option obscures
|
||||
shared secrets by replacing them with strings of question marks
|
||||
(``?``). This allows the contents of ``named.conf`` and related files
|
||||
to be shared - for example, when submitting bug reports -
|
||||
without compromising private data. This option cannot be used without
|
||||
``-p``.
|
||||
|
||||
``-z``
|
||||
This option performs a test load of all zones of type ``primary`` found in ``named.conf``.
|
||||
|
||||
``filename``
|
||||
This indicates the name of the configuration file to be checked. If not specified,
|
||||
it defaults to ``/etc/named.conf``.
|
||||
|
||||
Return Values
|
||||
~~~~~~~~~~~~~
|
||||
|
||||
``named-checkconf`` returns an exit status of 1 if errors were detected
|
||||
and 0 otherwise.

.SH "DESCRIPTION"
|

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

<para><command>named-checkzone</command>
|

checks the syntax and integrity of a zone file. It performs the
|
||||
same checks as <command>named</command> does when loading a
|
||||
zone. This makes <command>named-checkzone</command> useful for
|
||||
checking zone files before configuring them into a name server.

</para>
|

<para>
|
||||
<command>named-compilezone</command> is similar to
|
||||
<command>named-checkzone</command>, but it always dumps the
|
||||
zone contents to a specified file in a specified format.
|
||||
Additionally, it applies stricter check levels by default,
|
||||
since the dump output will be used as an actual zone file
|
||||
loaded by <command>named</command>.
|
||||
When manually specified otherwise, the check levels must at
|
||||
least be as strict as those specified in the
|
||||
<command>named</command> configuration file.

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

Mode <span class="command"><strong>"full"</strong></span> checks that delegation NS

in the zone match those advertised by the child.

Mode <span class="command"><strong>"local"</strong></span> only checks NS records which

refer to in-zone hostnames or that some required glue exists,

|

Description
|
||||
~~~~~~~~~~~
|
||||
|
||||
``named-checkzone`` checks the syntax and integrity of a zone file. It
|
||||
performs the same checks as ``named`` does when loading a zone. This
|
||||
makes ``named-checkzone`` useful for checking zone files before
|
||||
configuring them into a name server.
|
||||
|
||||
``named-compilezone`` is similar to ``named-checkzone``, but it always
|
||||
dumps the zone contents to a specified file in a specified format.
|
||||
It also applies stricter check levels by default, since the
|
||||
dump output is used as an actual zone file loaded by ``named``.
|
||||
When manually specified otherwise, the check levels must at least be as
|
||||
strict as those specified in the ``named`` configuration file.
|
||||
|
||||
Options
|
||||
~~~~~~~
|
||||
|
||||
``-d``
|
||||
This option enables debugging.
|
||||
|
||||
``-h``
|
||||
This option prints the usage summary and exits.
|
||||
|
||||
``-q``
|
||||
This option sets quiet mode, which only sets an exit code to indicate
|
||||
successful or failed completion.
|
||||
|
||||
``-v``
|
||||
This option prints the version of the ``named-checkzone`` program and exits.
|
||||
|
||||
``-j``
|
||||
When loading a zone file, this option tells ``named`` to read the journal if it exists. The journal
|
||||
file name is assumed to be the zone file name with the
|
||||
string ``.jnl`` appended.
|
||||
|
||||
``-J filename``
|
||||
When loading the zone file, this option tells ``named`` to read the journal from the given file, if
|
||||
it exists. This implies ``-j``.
|
||||
|
||||
``-c class``
|
||||
This option specifies the class of the zone. If not specified, ``IN`` is assumed.
|
||||
|
||||
``-i mode``
|
||||
This option performs post-load zone integrity checks. Possible modes are
|
||||
``full`` (the default), ``full-sibling``, ``local``,
|
||||
``local-sibling``, and ``none``.
|
||||
|
||||
Mode ``full`` checks that MX records refer to A or AAAA records
|
||||
(both in-zone and out-of-zone hostnames). Mode ``local`` only
|
||||
checks MX records which refer to in-zone hostnames.
|
||||
|
||||
Mode ``full`` checks that SRV records refer to A or AAAA records
|
||||
(both in-zone and out-of-zone hostnames). Mode ``local`` only
|
||||
checks SRV records which refer to in-zone hostnames.
|
||||
|
||||
Mode ``full`` checks that delegation NS records refer to A or AAAA
|
||||
records (both in-zone and out-of-zone hostnames). It also checks that
|
||||
glue address records in the zone match those advertised by the child.
|
||||
Mode ``local`` only checks NS records which refer to in-zone
|
||||
hostnames or verifies that some required glue exists, i.e., when the
|
||||
name server is in a child zone.
|
||||
|
||||
Modes ``full-sibling`` and ``local-sibling`` disable sibling glue
|
||||
checks, but are otherwise the same as ``full`` and ``local``,
|
||||
respectively.
|
||||
|
||||
Mode ``none`` disables the checks.
|
||||
|
||||
``-f format``
|
||||
This option specifies the format of the zone file. Possible formats are
|
||||
``text`` (the default), and ``raw``.
|
||||
|
||||
``-F format``
|
||||
This option specifies the format of the output file specified. For
|
||||
``named-checkzone``, this does not have any effect unless it dumps
|
||||
the zone contents.
|
||||
|
||||
Possible formats are ``text`` (the default), which is the standard
|
||||
textual representation of the zone, and ``raw`` and ``raw=N``, which
|
||||
store the zone in a binary format for rapid loading by ``named``.
|
||||
``raw=N`` specifies the format version of the raw zone file: if ``N`` is
|
||||
0, the raw file can be read by any version of ``named``; if N is 1, the
|
||||
file can only be read by release 9.9.0 or higher. The default is 1.
|
||||
|
||||
``-k mode``
|
||||
This option performs ``check-names`` checks with the specified failure mode.
|
||||
Possible modes are ``fail`` (the default for ``named-compilezone``),
|
||||
``warn`` (the default for ``named-checkzone``), and ``ignore``.
|
||||
|
||||
``-l ttl``
|
||||
This option sets a maximum permissible TTL for the input file. Any record with a
|
||||
TTL higher than this value causes the zone to be rejected. This
|
||||
is similar to using the ``max-zone-ttl`` option in ``named.conf``.
|
||||
|
||||
``-L serial``
|
||||
When compiling a zone to ``raw`` format, this option sets the "source
|
||||
serial" value in the header to the specified serial number. This is
|
||||
expected to be used primarily for testing purposes.
|
||||
|
||||
``-m mode``
|
||||
This option specifies whether MX records should be checked to see if they are
|
||||
addresses. Possible modes are ``fail``, ``warn`` (the default), and
|
||||
``ignore``.
|
||||
|
||||
``-M mode``
|
||||
This option checks whether a MX record refers to a CNAME. Possible modes are
|
||||
``fail``, ``warn`` (the default), and ``ignore``.
|
||||
|
||||
``-n mode``
|
||||
This option specifies whether NS records should be checked to see if they are
|
||||
addresses. Possible modes are ``fail`` (the default for
|
||||
``named-compilezone``), ``warn`` (the default for ``named-checkzone``),
|
||||
and ``ignore``.
|
||||
|
||||
``-o filename``
|
||||
This option writes the zone output to ``filename``. If ``filename`` is ``-``, then
|
||||
the zone output is written to standard output. This is mandatory for ``named-compilezone``.
|
||||
|
||||
``-r mode``
|
||||
This option checks for records that are treated as different by DNSSEC but are
|
||||
semantically equal in plain DNS. Possible modes are ``fail``,
|
||||
``warn`` (the default), and ``ignore``.
|
||||
|
||||
``-s style``
|
||||
This option specifies the style of the dumped zone file. Possible styles are
|
||||
``full`` (the default) and ``relative``. The ``full`` format is most
|
||||
suitable for processing automatically by a separate script.
|
||||
The relative format is more human-readable and is thus
|
||||
suitable for editing by hand. For ``named-checkzone``, this does not
|
||||
have any effect unless it dumps the zone contents. It also does not
|
||||
have any meaning if the output format is not text.
|
||||
|
||||
``-S mode``
|
||||
This option checks whether an SRV record refers to a CNAME. Possible modes are
|
||||
``fail``, ``warn`` (the default), and ``ignore``.
|
||||
|
||||
``-t directory``
|
||||
This option tells ``named`` to chroot to ``directory``, so that ``include`` directives in the
|
||||
configuration file are processed as if run by a similarly chrooted
|
||||
``named``.
|
||||
|
||||
``-T mode``
|
||||
This option checks whether Sender Policy Framework (SPF) records exist and issues a
|
||||
warning if an SPF-formatted TXT record is not also present. Possible
|
||||
modes are ``warn`` (the default) and ``ignore``.
|
||||
|
||||
``-w directory``
|
||||
This option instructs ``named`` to chdir to ``directory``, so that relative filenames in master file
|
||||
``$INCLUDE`` directives work. This is similar to the directory clause in
|
||||
``named.conf``.
|
||||
|
||||
``-D``
|
||||
This option dumps the zone file in canonical format. This is always enabled for
|
||||
``named-compilezone``.
|
||||
|
||||
``-W mode``
|
||||
This option specifies whether to check for non-terminal wildcards. Non-terminal
|
||||
wildcards are almost always the result of a failure to understand the
|
||||
wildcard matching algorithm (:rfc:`1034`). Possible modes are ``warn``
|
||||
(the default) and ``ignore``.
|
||||
|
||||
``zonename``
|
||||
This indicates the domain name of the zone being checked.
|
||||
|
||||
``filename``
|
||||
This is the name of the zone file.
|
||||
|
||||
Return Values
|
||||
~~~~~~~~~~~~~
|
||||
|
||||
``named-checkzone`` returns an exit status of 1 if errors were detected
|
||||
and 0 otherwise.

\fBtsig\-keygen\fR

|
||||
|
||||
<p>
|
||||
<span class="command"><strong>tsig-keygen</strong></span> and <span class="command"><strong>ddns-confgen</strong></span>
|
||||
are invocation methods for a utility that generates keys for use
|
||||
in TSIG signing. The resulting keys can be used, for example,
|
||||
to secure dynamic DNS updates to a zone or for the
|
||||
<span class="command"><strong>rndc</strong></span> command channel.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
When run as <span class="command"><strong>tsig-keygen</strong></span>, a domain name
|
||||
can be specified on the command line which will be used as
|
||||
the name of the generated key. If no name is specified,
|
||||
the default is <code class="constant">tsig-key</code>.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
When run as <span class="command"><strong>ddns-confgen</strong></span>, the generated
|
||||
key is accompanied by configuration text and instructions
|
||||
that can be used with <span class="command"><strong>nsupdate</strong></span> and
|
||||
<span class="command"><strong>named</strong></span> when setting up dynamic DNS,
|
||||
including an example <span class="command"><strong>update-policy</strong></span>
|
||||
statement. (This usage similar to the
|
||||
<span class="command"><strong>rndc-confgen</strong></span> command for setting
|
||||
up command channel security.)
|
||||
</p>
|
||||
|
||||
<p>
|
||||
Note that <span class="command"><strong>named</strong></span> itself can configure a
|
||||
local DDNS key for use with <span class="command"><strong>nsupdate -l</strong></span>:
|
||||
it does this when a zone is configured with
|
||||
<span class="command"><strong>update-policy local;</strong></span>.
|
||||
<span class="command"><strong>ddns-confgen</strong></span> is only needed when a
|
||||
more elaborate configuration is required: for instance,
|
||||
if <span class="command"><strong>nsupdate</strong></span> is to be used from a remote
|
||||
system.

|
||||
choices are: hmac-md5, hmac-sha1, hmac-sha224, hmac-sha256,
|
||||
hmac-sha384 and hmac-sha512. The default is hmac-sha256.
|

|
||||
<dd>
|
||||
<p>
|

Specifies the key name of the DDNS authentication key.
|
||||
The default is <code class="constant">ddns-key</code> when neither
|
||||
the <code class="option">-s</code> nor <code class="option">-z</code> option is
|
||||
specified; otherwise, the default
|
||||
is <code class="constant">ddns-key</code> as a separate label
|
||||
followed by the argument of the option, e.g.,
|
||||
<code class="constant">ddns-key.example.com.</code>
|
||||
The key name must have the format of a valid domain name,
|
||||
consisting of letters, digits, hyphens and periods.

\fBrndc\-confgen\fR
|

\fBrndc\fR\&. It can be used as a convenient alternative to writing the
|

rndc\&.conf
|

file and the corresponding
|

\fBcontrols\fR
|
||||
and
|
||||
\fBkey\fR
|
||||
statements in
|
||||
named\&.conf
|
||||
by hand\&. Alternatively, it can be run with the
|
||||
\fB\-a\fR
|
||||
option to set up a
|
||||
rndc\&.key
|
||||
file and avoid the need for a
|

Do automatic

configuration\&. This creates a file

\fIsysconfdir\fR

was built) that is read by both
|

\fBrndc\fR
|
||||
and
|
||||
\fBnamed\fR
|

on startup\&. The
|

rndc\&.key
|

\fBrndc\fR

to communicate with

\fBnamed\fR

on the local host with no further configuration\&.
|

.sp
|

Running
|

\fBrndc\-confgen \-a\fR

allows BIND 9 and

\fBrndc\fR

If a more elaborate configuration than that generated by

rndc-confgen - rndc key generation tool
|

---------------------------------------
|
||||
|
||||
Synopsis
|
||||
~~~~~~~~
|
||||
|
||||
:program:`rndc-confgen` [**-a**] [**-A** algorithm] [**-b** keysize] [**-c** keyfile] [**-h**] [**-k** keyname] [**-p** port] [**-s** address] [**-t** chrootdir] [**-u** user]
|
||||
|
||||
Description
|
||||
~~~~~~~~~~~
|
||||
|
||||
``rndc-confgen`` generates configuration files for ``rndc``. It can be
|
||||
used as a convenient alternative to writing the ``rndc.conf`` file and
|
||||
the corresponding ``controls`` and ``key`` statements in ``named.conf``
|
||||
by hand. Alternatively, it can be run with the ``-a`` option to set up a
|
||||
``rndc.key`` file and avoid the need for a ``rndc.conf`` file and a
|
||||
``controls`` statement altogether.
|
||||
|
||||
Options
|
||||
~~~~~~~
|
||||
|
||||
``-a``
|
||||
This option sets automatic ``rndc`` configuration, which creates a file ``rndc.key``
|
||||
in ``/etc`` (or a different ``sysconfdir`` specified when BIND
|
||||
was built) that is read by both ``rndc`` and ``named`` on startup.
|
||||
The ``rndc.key`` file defines a default command channel and
|
||||
authentication key allowing ``rndc`` to communicate with ``named`` on
|
||||
the local host with no further configuration.
|
||||
|
||||
If a more elaborate configuration than that generated by
|
||||
``rndc-confgen -a`` is required, for example if rndc is to be used
|
||||
remotely, run ``rndc-confgen`` without the ``-a`` option
|
||||
and set up ``rndc.conf`` and ``named.conf`` as directed.
|
||||
|
||||
``-A algorithm``
|
||||
This option specifies the algorithm to use for the TSIG key. Available choices
|
||||
are: hmac-md5, hmac-sha1, hmac-sha224, hmac-sha256, hmac-sha384, and
|
||||
hmac-sha512. The default is hmac-sha256.
|
||||
|
||||
``-b keysize``
|
||||
This option specifies the size of the authentication key in bits. The size must be between
|
||||
1 and 512 bits; the default is the hash size.
|
||||
|
||||
``-c keyfile``
|
||||
This option is used with the ``-a`` option to specify an alternate location for
|
||||
``rndc.key``.
|
||||
|
||||
``-h``
|
||||
This option prints a short summary of the options and arguments to
|
||||
``rndc-confgen``.
|
||||
|
||||
``-k keyname``
|
||||
This option specifies the key name of the ``rndc`` authentication key. This must be a
|
||||
valid domain name. The default is ``rndc-key``.
|
||||
|
||||
``-p port``
|
||||
This option specifies the command channel port where ``named`` listens for
|
||||
connections from ``rndc``. The default is 953.
|
||||
|
||||
``-q``
|
||||
This option prevets printing the written path in automatic configuration mode.
|
||||
|
||||
``-s address``
|
||||
This option specifies the IP address where ``named`` listens for command-channel
|
||||
connections from ``rndc``. The default is the loopback address
|
||||
127.0.0.1.
|
||||
|
||||
``-t chrootdir``
|
||||
This option is used with the ``-a`` option to specify a directory where ``named``
|
||||
runs chrooted. An additional copy of the ``rndc.key`` is
|
||||
written relative to this directory, so that it is found by the
|
||||
chrooted ``named``.
|
||||
|
||||
``-u user``
|
||||
This option is used with the ``-a`` option to set the owner of the generated ``rndc.key`` file.
|
||||
If ``-t`` is also specified, only the file in the chroot
|
||||
area has its owner changed.
|
||||
|
||||
Examples
|
||||
~~~~~~~~
|
||||
|
||||
To allow ``rndc`` to be used with no manual configuration, run:
|
||||
|
||||
``rndc-confgen -a``
|
||||
|
||||
To print a sample ``rndc.conf`` file and the corresponding ``controls`` and
|
||||
``key`` statements to be manually inserted into ``named.conf``, run:
|
||||
|
||||
``rndc-confgen``

tsig-keygen, ddns-confgen - TSIG key generation tool
|
||||
----------------------------------------------------
|
||||
|
||||
Synopsis
|
||||
~~~~~~~~
|
||||
:program:`tsig-keygen` [**-a** algorithm] [**-h**] [**-r** randomfile] [name]
|
||||
|
||||
:program:`ddns-confgen` [**-a** algorithm] [**-h**] [**-k** keyname] [**-q**] [**-r** randomfile] [**-s** name] [**-z** zone]
|
||||
|
||||
Description
|
||||
~~~~~~~~~~~
|
||||
|
||||
``tsig-keygen`` and ``ddns-confgen`` are invocation methods for a
|
||||
utility that generates keys for use in TSIG signing. The resulting keys
|
||||
can be used, for example, to secure dynamic DNS updates to a zone, or for
|
||||
the ``rndc`` command channel.
|
||||
|
||||
When run as ``tsig-keygen``, a domain name can be specified on the
|
||||
command line to be used as the name of the generated key. If no
|
||||
name is specified, the default is ``tsig-key``.
|
||||
|
||||
When run as ``ddns-confgen``, the key name can specified using ``-k``
|
||||
parameter and defaults to ``ddns-key``. The generated key is accompanied
|
||||
by configuration text and instructions that can be used with ``nsupdate``
|
||||
and ``named`` when setting up dynamic DNS, including an example
|
||||
``update-policy`` statement. (This usage is similar to the ``rndc-confgen``
|
||||
command for setting up command-channel security.)
|
||||
|
||||
Note that ``named`` itself can configure a local DDNS key for use with
|
||||
``nsupdate -l``; it does this when a zone is configured with
|
||||
``update-policy local;``. ``ddns-confgen`` is only needed when a more
|
||||
elaborate configuration is required: for instance, if ``nsupdate`` is to
|
||||
be used from a remote system.
|
||||
|
||||
Options
|
||||
~~~~~~~
|
||||
|
||||
``-a algorithm``
|
||||
This option specifies the algorithm to use for the TSIG key. Available
|
||||
choices are: hmac-md5, hmac-sha1, hmac-sha224, hmac-sha256, hmac-sha384,
|
||||
and hmac-sha512. The default is hmac-sha256. Options are
|
||||
case-insensitive, and the "hmac-" prefix may be omitted.
|
||||
|
||||
``-h``
|
||||
This option prints a short summary of options and arguments.
|
||||
|
||||
``-k keyname``
|
||||
This option specifies the key name of the DDNS authentication key. The
|
||||
default is ``ddns-key`` when neither the ``-s`` nor ``-z`` option is
|
||||
specified; otherwise, the default is ``ddns-key`` as a separate label
|
||||
followed by the argument of the option, e.g., ``ddns-key.example.com.``
|
||||
The key name must have the format of a valid domain name, consisting of
|
||||
letters, digits, hyphens, and periods.
|
||||
|
||||
``-q`` (``ddns-confgen`` only)
|
||||
This option enables quiet mode, which prints only the key, with no
|
||||
explanatory text or usage examples. This is essentially identical to
|
||||
``tsig-keygen``.
|
||||
|
||||
``-s name`` (``ddns-confgen`` only)
|
||||
This option generates a configuration example to allow dynamic updates
|
||||
of a single hostname. The example ``named.conf`` text shows how to set
|
||||
an update policy for the specified name using the "name" nametype. The
|
||||
default key name is ``ddns-key.name``. Note that the "self" nametype
|
||||
cannot be used, since the name to be updated may differ from the key
|
||||
name. This option cannot be used with the ``-z`` option.
|
||||
|
||||
``-z zone`` (``ddns-confgen`` only)
|
||||
This option generates a configuration example to allow
|
||||
dynamic updates of a zone. The example ``named.conf`` text shows how
|
||||
to set an update policy for the specified zone using the "zonesub"
|
||||
nametype, allowing updates to all subdomain names within that zone.
|
||||
This option cannot be used with the ``-s`` option.

.SH "DESCRIPTION"
|
||||
.PP
|
||||
\fBdelv\fR
|
||||
is a tool for sending DNS queries and validating the results, using the same internal resolver and validator logic as
|
||||
\fBnamed\fR\&.
|
||||
.PP
|
||||
\fBdelv\fR
|
||||
will send to a specified name server all queries needed to fetch and validate the requested data; this includes the original requested query, subsequent queries to follow CNAME or DNAME chains, and queries for DNSKEY and DS records to establish a chain of trust for DNSSEC validation\&. It does not perform iterative resolution, but simulates the behavior of a name server configured for DNSSEC validating and forwarding\&.
|
||||
.PP
|
||||
By default, responses are validated using built\-in DNSSEC trust anchor for the root zone ("\&.")\&. Records returned by
|
||||
\fBdelv\fR
|
||||
are either fully validated or were not signed\&. If validation fails, an explanation of the failure is included in the output; the validation process can be traced in detail\&. Because
|
||||
\fBdelv\fR
|
||||
does not rely on an external server to carry out validation, it can be used to check the validity of DNS responses in environments where local name servers may not be trustworthy\&.
|
||||
.PP
|
||||
Unless it is told to query a specific name server,
|
||||
\fBdelv\fR
|
||||
will try each of the servers listed in
|
||||
/etc/resolv\&.conf\&. If no usable server addresses are found,
|
||||
\fBdelv\fR
|
||||
will send queries to the localhost addresses (127\&.0\&.0\&.1 for IPv4, ::1 for IPv6)\&.
|
||||
.PP
|
||||
When no command line arguments or options are given,
|
||||
\fBdelv\fR
|
||||
will perform an NS query for "\&." (the root zone)\&.
|
||||
.SH "SIMPLE USAGE"
|
||||
.PP
|
||||
A typical invocation of
|
||||
\fBdelv\fR
|
||||
looks like:
|
||||
.sp
|
||||
.if n \{\
|
||||
.RS 4
|
||||
.\}
|
||||
.nf
|
||||
delv @server name type
|
||||
.fi
|
||||
.if n \{\
|
||||
.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,
|
||||
\fBdelv\fR
|
||||
resolves that name before querying that name server (note, however, that this initial lookup is
|
||||
\fInot\fR
|
||||
validated by DNSSEC)\&.
|
||||
.sp
|
||||
If no
|
||||
\fIserver\fR
|
||||
argument is provided,
|
||||
\fBdelv\fR
|
||||
consults
|
||||
/etc/resolv\&.conf; if an address is found there, it queries the name server at that address\&. If either of the
|
||||
\fB\-4\fR
|
||||
or
|
||||
\fB\-6\fR
|
||||
options are in use, then only addresses for the corresponding transport will be tried\&. If no usable addresses are found,
|
||||
\fBdelv\fR
|
||||
will send queries to the localhost addresses (127\&.0\&.0\&.1 for IPv4, ::1 for IPv6)\&.
|
||||
.RE
|
||||
.PP
|
||||
\fBname\fR
|
||||
.RS 4
|
||||
is the domain name to be looked up\&.
|
||||
.RE
|
||||
.PP
|
||||
\fBtype\fR
|
||||
.RS 4
|
||||
indicates what type of query is required \(em ANY, A, MX, etc\&.
|
||||
\fItype\fR
|
||||
can be any valid query type\&. If no
|
||||
\fItype\fR
|
||||
argument is supplied,
|
||||
\fBdelv\fR
|
||||
will perform a lookup for an A record\&.
|
||||
.RE
|
||||
.SH "OPTIONS"
|
||||
.PP
|
||||
\-a \fIanchor\-file\fR
|
||||
.RS 4
|
||||
Specifies a file from which to read DNSSEC trust anchors\&. The default is
|
||||
/etc/bind\&.keys, which is included with
|
||||
BIND
|
||||
9 and contains one or more trust anchors for the root zone ("\&.")\&.
|
||||
.sp
|
||||
Keys that do not match the root zone name are ignored\&. An alternate key name can be specified using the
|
||||
\fB+root=NAME\fR
|
||||
options\&.
|
||||
.sp
|
||||
Note: When reading the trust anchor file,
|
||||
\fBdelv\fR
|
||||
treats
|
||||
\fBtrust\-anchors\fR\fBinitial\-key\fR
|
||||
and
|
||||
\fBstatic\-key\fR
|
||||
entries identically\&. That is, even if a key is configured with
|
||||
\fBinitial\-key\fR, indicating that it is meant to be used only as an initializing key for RFC 5011 key maintenance, it is still treated by
|
||||
\fBdelv\fR
|
||||
as if it had been configured as a
|
||||
\fBstatic\-key\fR\&.
|
||||
\fBdelv\fR
|
||||
does not consult the managed keys database maintained by
|
||||
\fBnamed\fR\&. This means that if either of the keys in
|
||||
/etc/bind\&.keys
|
||||
is revoked and rolled over, it will be necessary to update
|
||||
/etc/bind\&.keys
|
||||
to use DNSSEC validation in
|
||||
\fBdelv\fR\&.
|
||||
.RE
|
||||
.PP
|
||||
\-b \fIaddress\fR
|
||||
.RS 4
|
||||
Sets the source IP address of the query to
|
||||
\fIaddress\fR\&. This must be a valid address on one of the host\*(Aqs network interfaces or "0\&.0\&.0\&.0" or "::"\&. An optional source port may be specified by appending "#<port>"
|

.RE
|
||||
.PP
|

\-c \fIclass\fR
|

.RS 4
|

Sets the query class for the requested data\&. Currently, only class "IN" is supported in

\fBdelv\fR
|

and any other value is ignored\&.
|

.RE
|
||||
.PP
|

\-d \fIlevel\fR
|
||||
.RS 4
|
||||
Set the systemwide debug level to
|
||||
\fBlevel\fR\&. The allowed range is from 0 to 99\&. The default is 0 (no debugging)\&. Debugging traces from
|
||||
\fBdelv\fR
|
||||
become more verbose as the debug level increases\&. See the
|
||||
\fB+mtrace\fR,
|

\fB+vtrace\fR
|

options below for additional debugging details\&.

Insecure mode\&. This disables internal DNSSEC validation\&. (Note, however, this does not set the CD bit on upstream queries\&. If the server being queried is performing DNSSEC validation, then it will not return invalid data; this can cause
|
||||
\fBdelv\fR
|
||||
to time out\&. When it is necessary to examine invalid data to debug a DNSSEC problem, use
|
||||
\fBdig +cd\fR\&.)

\-p \fIport#\fR
|

Specifies a destination port to use for queries instead of the standard DNS port number 53\&. This option would be used with a name server that has been configured to listen for queries on a non\-standard port number\&.
|

.RE
|
||||
.PP
|
||||
\-q \fIname\fR
|
||||
.RS 4
|
||||
Sets the query name to
|
||||
\fIname\fR\&. While the query name can be specified without using the
|
||||
\fB\-q\fR, it is sometimes necessary to disambiguate names from types or classes (for example, when looking up the name "ns", which could be misinterpreted as the type NS, or "ch", which could be misinterpreted as class CH)\&.
|
||||
.RE
|
||||
.PP
|
||||
\-t \fItype\fR
|
||||
.RS 4
|

Sets the query type to
|
||||
\fItype\fR, which can be any valid query type supported in BIND 9 except for zone transfer types AXFR and IXFR\&. As with
|
||||
\fB\-q\fR, this is useful to distinguish query name type or class when they are ambiguous\&. it is sometimes necessary to disambiguate names from types\&.
|
||||
.sp
|
||||
The default query type is "A", unless the
|
||||
\fB\-x\fR
|

option is supplied to indicate a reverse lookup, in which case it is "PTR"\&.

Performs a reverse lookup, mapping an addresses to a name\&.
|

\fIaddr\fR
|

is an IPv4 address in dotted\-decimal notation, or a colon\-delimited IPv6 address\&. When

\fB\-x\fR

is used, there is no need to provide the
|

\fIname\fR
|
||||
or
|

\fItype\fR
|
||||
arguments\&.
|
||||
\fBdelv\fR
|

automatically performs a lookup for a name like
|
||||
11\&.12\&.13\&.10\&.in\-addr\&.arpa
|

and sets the query type to PTR\&. IPv6 addresses are looked up using nibble format under the IP6\&.ARPA domain\&.

Controls whether to set the CD (checking disabled) bit in queries sent by

\fBdelv\fR\&. This may be useful when troubleshooting DNSSEC problems from behind a validating resolver\&. A validating resolver will block invalid responses, making it difficult to retrieve them for analysis\&. Setting the CD flag on queries will cause the resolver to return invalid responses, which

<para><command>delv</command>
|
||||
is a tool for sending
|
||||
DNS queries and validating the results, using the same internal
|
||||
resolver and validator logic as <command>named</command>.
|
||||
</para>
|
||||
<para>
|
||||
<command>delv</command> will send to a specified name server all
|
||||
queries needed to fetch and validate the requested data; this
|
||||
includes the original requested query, subsequent queries to follow
|
||||
CNAME or DNAME chains, and queries for DNSKEY and DS records
|
||||
to establish a chain of trust for DNSSEC validation.
|
||||
It does not perform iterative resolution, but simulates the
|
||||
behavior of a name server configured for DNSSEC validating and
|
||||
forwarding.
|
||||
</para>
|
||||
<para>
|
||||
By default, responses are validated using built-in DNSSEC trust
|
||||
anchor for the root zone ("."). Records returned by
|
||||
<command>delv</command> are either fully validated or
|
||||
were not signed. If validation fails, an explanation of
|
||||
the failure is included in the output; the validation process
|
||||
can be traced in detail. Because <command>delv</command> does
|
||||
not rely on an external server to carry out validation, it can
|
||||
be used to check the validity of DNS responses in environments
|
||||
where local name servers may not be trustworthy.
|
||||
</para>
|
||||
<para>
|
||||
Unless it is told to query a specific name server,
|
||||
<command>delv</command> will try each of the servers listed in
|
||||
<filename>/etc/resolv.conf</filename>. If no usable server
|
||||
addresses are found, <command>delv</command> will send
|
||||
queries to the localhost addresses (127.0.0.1 for IPv4, ::1
|
||||
for IPv6).
|
||||
</para>
|
||||
<para>
|
||||
When no command line arguments or options are given,
|
||||
<command>delv</command> will perform an NS query for "."
|
||||
(the root zone).

A typical invocation of <command>delv</command> looks like:

<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>delv</command> resolves that name before
|
||||
querying that name server (note, however, that this
|
||||
initial lookup is <emphasis>not</emphasis> validated
|
||||
by DNSSEC).
|
||||
</para>
|
||||
<para>
|
||||
If no <parameter>server</parameter> argument is
|
||||
provided, <command>delv</command> consults
|
||||
<filename>/etc/resolv.conf</filename>; if an
|
||||
address is found there, it queries the name server at
|
||||
that address. If either of the <option>-4</option> or
|
||||
<option>-6</option> options are in use, then
|
||||
only addresses for the corresponding transport
|
||||
will be tried. If no usable addresses are found,
|
||||
<command>delv</command> will send queries to
|
||||
the localhost addresses (127.0.0.1 for IPv4,
|
||||
::1 for IPv6).

<para>

Specifies a file from which to read DNSSEC trust anchors.
|
||||
The default is <filename>/etc/bind.keys</filename>, which
|
||||
is included with <acronym>BIND</acronym> 9 and contains
|
||||
one or more trust anchors for the root zone (".").
|

</para>
|

<para>
|

Keys that do not match the root zone name are ignored.

An alternate key name can be specified using the

<option>+root=NAME</option> options.
|
||||
</para>
|
||||
<para>
|
||||
Note: When reading the trust anchor file,
|
||||
<command>delv</command> treats <option>trust-anchors</option>
|
||||
<option>initial-key</option> and <option>static-key</option>
|
||||
entries identically. That is, even if a key is configured
|
||||
with <command>initial-key</command>, indicating that it is
|
||||
meant to be used only as an initializing key for RFC 5011
|
||||
key maintenance, it is still treated by <command>delv</command>
|
||||
as if it had been configured as a <command>static-key</command>.
|
||||
<command>delv</command> does not consult the managed keys
|
||||
database maintained by <command>named</command>. This means
|
||||
that if either of the keys in
|
||||
<filename>/etc/bind.keys</filename> is revoked
|
||||
and rolled over, it will be necessary to update
|

<filename>/etc/bind.keys</filename> to use DNSSEC

validation in <command>delv</command>.

||||
displayed, and in some cases the way lookups are performed.
|
||||
</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]cdflag</option></term>
|
||||
<listitem>
|
||||
<para>
|
||||
Controls whether to set the CD (checking disabled) bit in
|
||||
queries sent by <command>delv</command>. This may be useful
|
||||
when troubleshooting DNSSEC problems from behind a validating
|
||||
resolver. A validating resolver will block invalid responses,
|
||||
making it difficult to retrieve them for analysis. Setting
|
||||
the CD flag on queries will cause the resolver to return
|
||||
invalid responses, which <command>delv</command> can then
|
||||
validate internally and report the errors in detail.

<a name="id-1.7"></a><h2>DESCRIPTION</h2>
|
||||
|
||||
<p><span class="command"><strong>delv</strong></span>
|
||||
is a tool for sending
|
||||
DNS queries and validating the results, using the same internal
|
||||
resolver and validator logic as <span class="command"><strong>named</strong></span>.
|
||||
</p>
|
||||
<p>
|
||||
<span class="command"><strong>delv</strong></span> will send to a specified name server all
|
||||
queries needed to fetch and validate the requested data; this
|
||||
includes the original requested query, subsequent queries to follow
|
||||
CNAME or DNAME chains, and queries for DNSKEY and DS records
|
||||
to establish a chain of trust for DNSSEC validation.
|
||||
It does not perform iterative resolution, but simulates the
|
||||
behavior of a name server configured for DNSSEC validating and
|
||||
forwarding.
|
||||
</p>
|
||||
<p>
|
||||
By default, responses are validated using built-in DNSSEC trust
|
||||
anchor for the root zone ("."). Records returned by
|
||||
<span class="command"><strong>delv</strong></span> are either fully validated or
|
||||
were not signed. If validation fails, an explanation of
|
||||
the failure is included in the output; the validation process
|
||||
can be traced in detail. Because <span class="command"><strong>delv</strong></span> does
|
||||
not rely on an external server to carry out validation, it can
|
||||
be used to check the validity of DNS responses in environments
|
||||
where local name servers may not be trustworthy.
|
||||
</p>
|
||||
<p>
|
||||
Unless it is told to query a specific name server,
|
||||
<span class="command"><strong>delv</strong></span> will try each of the servers listed in
|
||||
<code class="filename">/etc/resolv.conf</code>. If no usable server
|
||||
addresses are found, <span class="command"><strong>delv</strong></span> will send
|
||||
queries to the localhost addresses (127.0.0.1 for IPv4, ::1
|
||||
for IPv6).
|
||||
</p>
|
||||
<p>
|
||||
When no command line arguments or options are given,
|
||||
<span class="command"><strong>delv</strong></span> will perform an NS query for "."
|
||||
(the root zone).
|
||||

|
||||
|
||||
|
||||
<p>
|
||||
A typical invocation of <span class="command"><strong>delv</strong></span> looks like:
|
||||
</p>
|
||||
<pre class="programlisting"> delv @server name type </pre>
|
||||
<p>
|
||||
where:
|
||||
|
||||
</p>
|
||||
<div class="variablelist"><dl class="variablelist">
|
||||
<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 class="command"><strong>delv</strong></span> resolves that name before
|
||||
querying that name server (note, however, that this
|
||||
initial lookup is <span class="emphasis"><em>not</em></span> validated
|
||||
by DNSSEC).
|
||||
</p>
|
||||
<p>
|
||||
If no <em class="parameter"><code>server</code></em> argument is
|
||||
provided, <span class="command"><strong>delv</strong></span> consults
|
||||
<code class="filename">/etc/resolv.conf</code>; if an
|
||||
address is found there, it queries the name server at
|
||||
that address. If either of the <code class="option">-4</code> or
|
||||
<code class="option">-6</code> options are in use, then
|
||||
only addresses for the corresponding transport
|
||||
will be tried. If no usable addresses are found,
|
||||
<span class="command"><strong>delv</strong></span> will send queries to
|
||||
the localhost addresses (127.0.0.1 for IPv4,
|
||||
::1 for IPv6).
|
||||
</p>

ANY, A, MX, 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 class="command"><strong>delv</strong></span> will perform a lookup for an
|
||||
A record.

Note: When reading the trust anchor file,

<code class="option">initial-key</code> and <code class="option">static-key</code>

entries identically. That is, even if a key is configured

with <span class="command"><strong>initial-key</strong></span>, indicating that it is
|

meant to be used only as an initializing key for RFC 5011
|

key maintenance, it is still treated by <span class="command"><strong>delv</strong></span>
|

as if it had been configured as a <span class="command"><strong>static-key</strong></span>.
|

<span class="command"><strong>delv</strong></span> does not consult the managed keys

|

that if either of the keys in

While the query name can be specified without using the

Description
|
||||
~~~~~~~~~~~
|
||||
|
||||
``delv`` is a tool for sending DNS queries and validating the results,
|
||||
using the same internal resolver and validator logic as ``named``.
|
||||
|
||||
``delv`` sends to a specified name server all queries needed to
|
||||
fetch and validate the requested data; this includes the original
|
||||
requested query, subsequent queries to follow CNAME or DNAME chains,
|
||||
queries for DNSKEY, and DS records to establish a chain of trust for
|
||||
DNSSEC validation. It does not perform iterative resolution, but
|
||||
simulates the behavior of a name server configured for DNSSEC validating
|
||||
and forwarding.
|
||||
|
||||
By default, responses are validated using the built-in DNSSEC trust anchor
|
||||
for the root zone ("."). Records returned by ``delv`` are either fully
|
||||
validated or were not signed. If validation fails, an explanation of the
|
||||
failure is included in the output; the validation process can be traced
|
||||
in detail. Because ``delv`` does not rely on an external server to carry
|
||||
out validation, it can be used to check the validity of DNS responses in
|
||||
environments where local name servers may not be trustworthy.
|
||||
|
||||
Unless it is told to query a specific name server, ``delv`` tries
|
||||
each of the servers listed in ``/etc/resolv.conf``. If no usable server
|
||||
addresses are found, ``delv`` sends queries to the localhost
|
||||
addresses (127.0.0.1 for IPv4, ::1 for IPv6).
|
||||
|
||||
When no command-line arguments or options are given, ``delv``
|
||||
performs an NS query for "." (the root zone).
|
||||
|
||||
Simple Usage
|
||||
~~~~~~~~~~~~
|
||||
|
||||
A typical invocation of ``delv`` looks like:
|
||||
|
||||
::
|
||||
|
||||
delv @server name type
|
||||
|
||||
where:
|
||||
|
||||
``server``
|
||||
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 ``server`` argument is a
|
||||
hostname, ``delv`` resolves that name before querying that name
|
||||
server (note, however, that this initial lookup is *not* validated by
|
||||
DNSSEC).
|
||||
|
||||
If no ``server`` argument is provided, ``delv`` consults
|
||||
``/etc/resolv.conf``; if an address is found there, it queries the
|
||||
name server at that address. If either of the ``-4`` or ``-6``
|
||||
options is in use, then only addresses for the corresponding
|
||||
transport are tried. If no usable addresses are found, ``delv``
|
||||
sends queries to the localhost addresses (127.0.0.1 for IPv4, ::1
|
||||
for IPv6).
|
||||
|
||||
``name``
|
||||
is the domain name to be looked up.
|
||||
|
||||
``type``
|
||||
indicates what type of query is required - ANY, A, MX, etc.
|
||||
``type`` can be any valid query type. If no ``type`` argument is
|
||||
supplied, ``delv`` performs a lookup for an A record.
|
||||
|
||||
Options
|
||||
~~~~~~~
|
||||
|
||||
``-a anchor-file``
|
||||
This option specifies a file from which to read DNSSEC trust anchors. The default
|
||||
is ``/etc/bind.keys``, which is included with BIND 9 and contains one
|
||||
or more trust anchors for the root zone (".").
|
||||
|
||||
Keys that do not match the root zone name are ignored. An alternate
|
||||
key name can be specified using the ``+root=NAME`` options.
|
||||
|
||||
Note: When reading the trust anchor file, ``delv`` treats ``trust-anchors``,
|
||||
``initial-key``, and ``static-key`` identically. That is, for a managed key,
|
||||
it is the *initial* key that is trusted; :rfc:`5011` key management is not
|
||||
supported. ``delv`` does not consult the managed-keys database maintained by
|
||||
``named``, which means that if either of the keys in ``/etc/bind.keys`` is
|
||||
revoked and rolled over, ``/etc/bind.keys`` must be updated to
|
||||
use DNSSEC validation in ``delv``.
|
||||
|
||||
``-b address``
|
||||
This option sets the source IP address of the query to ``address``. This must be
|
||||
a valid address on one of the host's network interfaces, or ``0.0.0.0``,
|
||||
or ``::``. An optional source port may be specified by appending
|
||||
``#<port>``
|
||||
|
||||
``-c class``
|
||||
This option sets the query class for the requested data. Currently, only class
|
||||
"IN" is supported in ``delv`` and any other value is ignored.
|
||||
|
||||
``-d level``
|
||||
This option sets the systemwide debug level to ``level``. The allowed range is
|
||||
from 0 to 99. The default is 0 (no debugging). Debugging traces from
|
||||
``delv`` become more verbose as the debug level increases. See the
|
||||
``+mtrace``, ``+rtrace``, and ``+vtrace`` options below for
|
||||
additional debugging details.
|
||||
|
||||
``-h``
|
||||
This option displays the ``delv`` help usage output and exits.
|
||||
|
||||
``-i``
|
||||
This option sets insecure mode, which disables internal DNSSEC validation. (Note,
|
||||
however, that this does not set the CD bit on upstream queries. If the
|
||||
server being queried is performing DNSSEC validation, then it does
|
||||
not return invalid data; this can cause ``delv`` to time out. When it
|
||||
is necessary to examine invalid data to debug a DNSSEC problem, use
|
||||
``dig +cd``.)
|
||||
|
||||
``-m``
|
||||
This option enables memory usage debugging.
|
||||
|
||||
``-p port#``
|
||||
This option specifies a destination port to use for queries, instead of the
|
||||
standard DNS port number 53. This option is used with a name
|
||||
server that has been configured to listen for queries on a
|
||||
non-standard port number.
|
||||
|
||||
``-q name``
|
||||
This option sets the query name to ``name``. While the query name can be
|
||||
specified without using the ``-q`` option, it is sometimes necessary to
|
||||
disambiguate names from types or classes (for example, when looking
|
||||
up the name "ns", which could be misinterpreted as the type NS, or
|
||||
"ch", which could be misinterpreted as class CH).
|
||||
|
||||
``-t type``
|
||||
This option sets the query type to ``type``, which can be any valid query type
|
||||
supported in BIND 9 except for zone transfer types AXFR and IXFR. As
|
||||
with ``-q``, this is useful to distinguish query-name types or classes
|
||||
when they are ambiguous. It is sometimes necessary to disambiguate
|
||||
names from types.
|
||||
|
||||
The default query type is "A", unless the ``-x`` option is supplied
|
||||
to indicate a reverse lookup, in which case it is "PTR".
|
||||
|
||||
``-v``
|
||||
This option prints the ``delv`` version and exits.
|
||||
|
||||
``-x addr``
|
||||
This option performs a reverse lookup, mapping an address to a name. ``addr``
|
||||
is an IPv4 address in dotted-decimal notation, or a colon-delimited
|
||||
IPv6 address. When ``-x`` is used, there is no need to provide the
|
||||
``name`` or ``type`` arguments; ``delv`` automatically performs a
|
||||
lookup for a name like ``11.12.13.10.in-addr.arpa`` and sets the
|
||||
query type to PTR. IPv6 addresses are looked up using nibble format
|
||||
under the IP6.ARPA domain.
|
||||
|
||||
``-4``
|
||||
This option forces ``delv`` to only use IPv4.
|
||||
|
||||
``-6``
|
||||
This option forces ``delv`` to only use IPv6.
|
||||
|
||||
Query Options
|
||||
~~~~~~~~~~~~~
|
||||
|
||||
``delv`` provides a number of query options which affect the way results
|
||||
are displayed, and in some cases the way lookups are performed.
|
||||
|
||||
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
|
||||
``+keyword=value``. The query options are:
|
||||
|
||||
``+[no]cdflag``
|
||||
This option controls whether to set the CD (checking disabled) bit in queries
|
||||
sent by ``delv``. This may be useful when troubleshooting DNSSEC
|
||||
problems from behind a validating resolver. A validating resolver
|
||||
blocks invalid responses, making it difficult to retrieve them
|
||||
for analysis. Setting the CD flag on queries causes the resolver
|
||||
to return invalid responses, which ``delv`` can then validate
|
||||
internally and report the errors in detail.
|
||||
|
||||
``+[no]class``
|
||||
This option controls whether to display the CLASS when printing a record. The
|
||||
default is to display the CLASS.
|
||||
|
||||
``+[no]ttl``
|
||||
This option controls whether to display the TTL when printing a record. The
|
||||
default is to display the TTL.
|
||||
|
||||
``+[no]rtrace``
|
||||
This option toggles resolver fetch logging. This reports the name and type of each
|
||||
query sent by ``delv`` in the process of carrying out the resolution
|
||||
and validation process, including the original query
|
||||
and all subsequent queries to follow CNAMEs and to establish a chain
|
||||
of trust for DNSSEC validation.
|
||||
|
||||
This is equivalent to setting the debug level to 1 in the "resolver"
|
||||
logging category. Setting the systemwide debug level to 1 using the
|
||||
``-d`` option produces the same output, but affects other
|
||||
logging categories as well.
|
||||
|
||||
``+[no]mtrace``
|
||||
This option toggles message logging. This produces a detailed dump of the
|
||||
responses received by ``delv`` in the process of carrying out the
|
||||
resolution and validation process.
|
||||
|
||||
This is equivalent to setting the debug level to 10 for the "packets"
|
||||
module of the "resolver" logging category. Setting the systemwide
|
||||
debug level to 10 using the ``-d`` option produces the same
|
||||
output, but affects other logging categories as well.
|
||||
|
||||
``+[no]vtrace``
|
||||
This option toggles validation logging. This shows the internal process of the
|
||||
validator as it determines whether an answer is validly signed,
|
||||
unsigned, or invalid.
|
||||
|
||||
This is equivalent to setting the debug level to 3 for the
|
||||
"validator" module of the "dnssec" logging category. Setting the
|
||||
systemwide debug level to 3 using the ``-d`` option produces the
|
||||
same output, but affects other logging categories as well.
|
||||
|
||||
``+[no]short``
|
||||
This option toggles between verbose and terse answers. The default is to print the answer in a
|
||||
verbose form.
|
||||
|
||||
``+[no]comments``
|
||||
This option toggles the display of comment lines in the output. The default is to
|
||||
print comments.
|
||||
|
||||
``+[no]rrcomments``
|
||||
This option toggles the display of per-record comments in the output (for example,
|
||||
human-readable key information about DNSKEY records). The default is
|
||||
to print per-record comments.
|
||||
|
||||
``+[no]crypto``
|
||||
This option toggles the display of cryptographic fields in DNSSEC records. The
|
||||
contents of these fields are unnecessary to debug most DNSSEC
|
||||
validation failures and removing them makes it easier to see the
|
||||
common failures. The default is to display the fields. When omitted,
|
||||
they are replaced by the string ``[omitted]`` or, in the DNSKEY case, the
|
||||
key ID is displayed as the replacement, e.g. ``[ key id = value ]``.
|
||||
|
||||
``+[no]trust``
|
||||
This option controls whether to display the trust level when printing a record.
|
||||
The default is to display the trust level.
|
||||
|
||||
``+[no]split[=W]``
|
||||
This option splits long hex- or base64-formatted fields in resource records into
|
||||
chunks of ``W`` characters (where ``W`` is rounded up to the nearest
|
||||
multiple of 4). ``+nosplit`` or ``+split=0`` causes fields not to be
|
||||
split at all. The default is 56 characters, or 44 characters when
|
||||
multiline mode is active.
|
||||
|
||||
``+[no]all``
|
||||
This option sets or clears the display options ``+[no]comments``,
|
||||
``+[no]rrcomments``, and ``+[no]trust`` as a group.
|
||||
|
||||
``+[no]multiline``
|
||||
This option prints long records (such as RRSIG, DNSKEY, and 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 ``delv`` output.
|
||||
|
||||
``+[no]dnssec``
|
||||
This option indicates whether to display RRSIG records in the ``delv`` output.
|
||||
The default is to do so. Note that (unlike in ``dig``) this does
|
||||
*not* control whether to request DNSSEC records or to
|
||||
validate them. DNSSEC records are always requested, and validation
|
||||
always occurs unless suppressed by the use of ``-i`` or
|
||||
``+noroot``.
|
||||
|
||||
``+[no]root[=ROOT]``
|
||||
This option indicates whether to perform conventional DNSSEC validation, and if so,
|
||||
specifies the name of a trust anchor. The default is to validate using a
|
||||
trust anchor of "." (the root zone), for which there is a built-in key. If
|
||||
specifying a different trust anchor, then ``-a`` must be used to specify a
|
||||
file containing the key.
|
||||
|
||||
``+[no]tcp``
|
||||
This option controls whether to use TCP when sending queries. The default is to
|
||||
use UDP unless a truncated response has been received.
|
||||
|
||||
``+[no]unknownformat``
|
||||
This option prints all RDATA in unknown RR-type presentation format (:rfc:`3597`).
|
||||
The default is to print RDATA for known types in the type's
|
||||
presentation format.
|
||||
|
||||
``+[no]yaml``
|
||||
This option prints response data in YAML format.

.SH "DESCRIPTION"
|
||||
.PP
|
||||
\fBdig\fR
|
||||
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
|
||||
/etc/resolv\&.conf\&. If no usable server addresses are found,
|
||||
\fBdig\fR
|
||||
will send the query to the local host\&.
|
||||
.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
|
||||
${HOME}/\&.digrc\&. This file is read and any options in it are applied before the command line arguments\&. The
|
||||
\fB\-r\fR
|
||||
option disables this feature, for scripts that need predictable behaviour\&.
|
||||
.PP
|
||||
The IN and CH class names overlap with the IN and CH top level domain names\&. Either use the
|
||||
\fB\-t\fR
|
||||
and
|
||||
\fB\-c\fR
|
||||
options to specify the type and class, use the
|
||||
\fB\-q\fR
|
||||
the specify the domain name, or use "IN\&." and "CH\&." when looking up these top level domains\&.
|
||||
.SH "SIMPLE USAGE"
|
||||
.PP
|
||||
A typical invocation of
|
||||
\fBdig\fR
|
||||
looks like:
|
||||
.sp
|

.if n \{\

|

.nf
|

.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\&.
|
||||
.sp
|
||||
If no
|
||||
\fIserver\fR
|
||||
argument is provided,
|
||||
\fBdig\fR
|
||||
consults
|
||||
/etc/resolv\&.conf; if an address is found there, it queries the name server at that address\&. If either of the
|
||||
\fB\-4\fR
|
||||
or
|
||||
\fB\-6\fR
|
||||
options are in use, then only addresses for the corresponding transport will be tried\&. If no usable addresses are found,
|
||||
\fBdig\fR
|
||||
will send the query to the local host\&. The reply from the name server that responds is displayed\&.

Description
|
||||
~~~~~~~~~~~
|
||||
|
||||
``dig`` 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 ``dig`` to
|
||||
troubleshoot DNS problems because of its flexibility, ease of use, and
|
||||
clarity of output. Other lookup tools tend to have less functionality
|
||||
than ``dig``.
|
||||
|
||||
Although ``dig`` 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 ``-h`` option is given. The BIND 9
|
||||
implementation of ``dig`` allows multiple lookups to be issued from the
|
||||
command line.
|
||||
|
||||
Unless it is told to query a specific name server, ``dig`` tries each
|
||||
of the servers listed in ``/etc/resolv.conf``. If no usable server
|
||||
addresses are found, ``dig`` sends the query to the local host.
|
||||
|
||||
When no command-line arguments or options are given, ``dig``
|
||||
performs an NS query for "." (the root).
|
||||
|
||||
It is possible to set per-user defaults for ``dig`` via
|
||||
``${HOME}/.digrc``. This file is read and any options in it are applied
|
||||
before the command-line arguments. The ``-r`` option disables this
|
||||
feature, for scripts that need predictable behavior.
|
||||
|
||||
The IN and CH class names overlap with the IN and CH top-level domain
|
||||
names. Either use the ``-t`` and ``-c`` options to specify the type and
|
||||
class, use the ``-q`` to specify the domain name, or use "IN." and
|
||||
"CH." when looking up these top-level domains.
|
||||
|
||||
Simple Usage
|
||||
~~~~~~~~~~~~
|
||||
|
||||
A typical invocation of ``dig`` looks like:
|
||||
|
||||
::
|
||||
|
||||
dig @server name type
|
||||
|
||||
where:
|
||||
|
||||
``server``
|
||||
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 ``server`` argument is a
|
||||
hostname, ``dig`` resolves that name before querying that name
|
||||
server.
|
||||
|
||||
If no ``server`` argument is provided, ``dig`` consults
|
||||
``/etc/resolv.conf``; if an address is found there, it queries the
|
||||
name server at that address. If either of the ``-4`` or ``-6``
|
||||
options are in use, then only addresses for the corresponding
|
||||
transport are tried. If no usable addresses are found, ``dig``
|
||||
sends the query to the local host. The reply from the name server
|
||||
that responds is displayed.
|
||||
|
||||
``name``
|
||||
is the name of the resource record that is to be looked up.
|
||||
|
||||
``type``
|
||||
indicates what type of query is required - ANY, A, MX, SIG, etc.
|
||||
``type`` can be any valid query type. If no ``type`` argument is
|
||||
supplied, ``dig`` performs a lookup for an A record.
|
||||
|
||||
Options
|
||||
~~~~~~~
|
||||
|
||||
``-4``
|
||||
This option indicates that only IPv4 should be used.
|
||||
|
||||
``-6``
|
||||
This option indicates that only IPv6 should be used.
|
||||
|
||||
``-b address[#port]``
|
||||
This option sets the source IP address of the query. The ``address`` 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``.
|
||||
|
||||
``-c class``
|
||||
This option sets the query class. The default ``class`` is IN; other classes are
|
||||
HS for Hesiod records or CH for Chaosnet records.
|
||||
|
||||
``-f file``
|
||||
This option sets batch mode, in which ``dig`` reads a list of lookup requests to process from
|
||||
the given ``file``. Each line in the file should be organized in the
|
||||
same way it would be presented as a query to ``dig`` using the
|
||||
command-line interface.
|
||||
|
||||
``-k keyfile``
|
||||
This option tells ``named`` to sign queries using TSIG using a key read from the given file. Key
|
||||
files can be generated using ``tsig-keygen``. When using TSIG
|
||||
authentication with ``dig``, 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 ``key`` and ``server`` statements in
|
||||
``named.conf``.
|
||||
|
||||
``-m``
|
||||
This option enables memory usage debugging.
|
||||
|
||||
``-p port``
|
||||
This option sends the query to a non-standard port on the server, instead of the
|
||||
default port 53. This option is used to test a name server that
|
||||
has been configured to listen for queries on a non-standard port
|
||||
number.
|
||||
|
||||
``-q name``
|
||||
This option specifies the domain name to query. This is useful to distinguish the ``name``
|
||||
from other arguments.
|
||||
|
||||
``-r``
|
||||
This option indicates that options from ``${HOME}/.digrc`` should not be read. This is useful for
|
||||
scripts that need predictable behavior.
|
||||
|
||||
``-t type``
|
||||
This option indicates the resource record type to query, which can be any valid query type. If
|
||||
it is a resource record type supported in BIND 9, it can be given by
|
||||
the type mnemonic (such as ``NS`` or ``AAAA``). The default query type is
|
||||
``A``, unless the ``-x`` 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, set the
|
||||
``type`` to ``ixfr=N``. The incremental zone transfer contains
|
||||
all changes made to the zone since the serial number in the zone's
|
||||
SOA record was ``N``.
|
||||
|
||||
All resource record types can be expressed as ``TYPEnn``, where ``nn`` is
|
||||
the number of the type. If the resource record type is not supported
|
||||
in BIND 9, the result is displayed as described in :rfc:`3597`.
|
||||
|
||||
``-u``
|
||||
This option indicates that print query times should be provided in microseconds instead of milliseconds.
|
||||
|
||||
``-v``
|
||||
This option prints the version number and exits.
|
||||
|
||||
``-x addr``
|
||||
This option sets simplified reverse lookups, for mapping addresses to names. The
|
||||
``addr`` is an IPv4 address in dotted-decimal notation, or a
|
||||
colon-delimited IPv6 address. When the ``-x`` option is used, there is no
|
||||
need to provide the ``name``, ``class``, and ``type`` arguments.
|
||||
``dig`` automatically performs a lookup for a name like
|
||||
``94.2.0.192.in-addr.arpa`` and sets the query type and class to PTR
|
||||
and IN respectively. IPv6 addresses are looked up using nibble format
|
||||
under the IP6.ARPA domain.
|
||||
|
||||
``-y [hmac:]keyname:secret``
|
||||
This option signs queries using TSIG with the given authentication key.
|
||||
``keyname`` is the name of the key, and ``secret`` is the
|
||||
base64-encoded shared secret. ``hmac`` is the name of the key algorithm;
|
||||
valid choices are ``hmac-md5``, ``hmac-sha1``, ``hmac-sha224``,
|
||||
``hmac-sha256``, ``hmac-sha384``, or ``hmac-sha512``. If ``hmac`` is
|
||||
not specified, the default is ``hmac-md5``; if MD5 was disabled, the default is
|
||||
``hmac-sha256``.
|
||||
|
||||
.. note:: Only the ``-k`` option should be used, rather than the ``-y`` option,
|
||||
because with ``-y`` the shared secret is supplied as a command-line
|
||||
argument in clear text. This may be visible in the output from ``ps1`` or
|
||||
in a history file maintained by the user's shell.
|
||||
|
||||
Query Options
|
||||
~~~~~~~~~~~~~
|
||||
|
||||
``dig`` 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.
|
||||
|
||||
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
|
||||
``+keyword=value``. Keywords may be abbreviated, provided the
|
||||
abbreviation is unambiguous; for example, ``+cd`` is equivalent to
|
||||
``+cdflag``. The query options are:
|
||||
|
||||
``+[no]aaflag``
|
||||
This option is a synonym for ``+[no]aaonly``.
|
||||
|
||||
``+[no]aaonly``
|
||||
This option sets the ``aa`` flag in the query.
|
||||
|
||||
``+[no]additional``
|
||||
This option displays [or does not display] the additional section of a reply. The
|
||||
default is to display it.
|
||||
|
||||
``+[no]adflag``
|
||||
This option sets [or does not set] the AD (authentic data) bit in the query. This
|
||||
requests the server to return whether all of the answer and authority
|
||||
sections have been validated as secure, according to the security
|
||||
policy of the server. ``AD=1`` indicates that all records have been
|
||||
validated as secure and the answer is not from a OPT-OUT range. ``AD=0``
|
||||
indicates that some part of the answer was insecure or not validated.
|
||||
This bit is set by default.
|
||||
|
||||
``+[no]all``
|
||||
This option sets or clears all display flags.
|
||||
|
||||
``+[no]answer``
|
||||
This option displays [or does not display] the answer section of a reply. The default
|
||||
is to display it.
|
||||
|
||||
``+[no]authority``
|
||||
This option displays [or does not display] the authority section of a reply. The
|
||||
default is to display it.
|
||||
|
||||
``+[no]badcookie``
|
||||
This option retries the lookup with a new server cookie if a BADCOOKIE response is
|
||||
received.
|
||||
|
||||
``+[no]besteffort``
|
||||
This option attempts to display the contents of messages which are malformed. The
|
||||
default is to not display malformed answers.
|
||||
|
||||
``+bufsize[=B]``
|
||||
This option sets the UDP message buffer size advertised using EDNS0 to
|
||||
``B`` bytes. The maximum and minimum sizes of this buffer are 65535 and
|
||||
0, respectively. ``+bufsize`` restores the default buffer size.
|
||||
|
||||
``+[no]cdflag``
|
||||
This option sets [or does not set] the CD (checking disabled) bit in the query. This
|
||||
requests the server to not perform DNSSEC validation of responses.
|
||||
|
||||
``+[no]class``
|
||||
This option displays [or does not display] the CLASS when printing the record.
|
||||
|
||||
``+[no]cmd``
|
||||
This option toggles the printing of the initial comment in the output, identifying the
|
||||
version of ``dig`` and the query options that have been applied. This option
|
||||
always has a global effect; it cannot be set globally and then overridden on a
|
||||
per-lookup basis. The default is to print this comment.
|
||||
|
||||
``+[no]comments``
|
||||
This option toggles the display of some comment lines in the output, with
|
||||
information about the packet header and OPT pseudosection, and the names of
|
||||
the response section. The default is to print these comments.
|
||||
|
||||
Other types of comments in the output are not affected by this option, but
|
||||
can be controlled using other command-line switches. These include
|
||||
``+[no]cmd``, ``+[no]question``, ``+[no]stats``, and ``+[no]rrcomments``.
|
||||
|
||||
``+[no]cookie=####``
|
||||
This option sends [or does not send] a COOKIE EDNS option, with an optional value. Replaying a COOKIE
|
||||
from a previous response allows the server to identify a previous
|
||||
client. The default is ``+cookie``.
|
||||
|
||||
``+cookie`` is also set when ``+trace`` is set to better emulate the
|
||||
default queries from a nameserver.
|
||||
|
||||
``+[no]crypto``
|
||||
This option toggles the display of cryptographic fields in DNSSEC records. The
|
||||
contents of these fields are unnecessary for debugging most DNSSEC
|
||||
validation failures and removing them makes it easier to see the
|
||||
common failures. The default is to display the fields. When omitted,
|
||||
they are replaced by the string ``[omitted]`` or, in the DNSKEY case, the
|
||||
key ID is displayed as the replacement, e.g. ``[ key id = value ]``.
|
||||
|
||||
``+[no]defname``
|
||||
This option, which is deprecated, is treated as a synonym for ``+[no]search``.
|
||||
|
||||
``+[no]dns64prefix``
|
||||
Lookup IPV4ONLY.ARPA AAAA and print any DNS64 prefixes found.
|
||||
|
||||
``+[no]dnssec``
|
||||
This option requests that DNSSEC records be sent by setting the DNSSEC OK (DO) bit in
|
||||
the OPT record in the additional section of the query.
|
||||
|
||||
``+domain=somename``
|
||||
This option sets the search list to contain the single domain ``somename``, as if
|
||||
specified in a ``domain`` directive in ``/etc/resolv.conf``, and
|
||||
enables search list processing as if the ``+search`` option were
|
||||
given.
|
||||
|
||||
``+dscp=value``
|
||||
This option sets the DSCP code point to be used when sending the query. Valid DSCP
|
||||
code points are in the range [0...63]. By default no code point is
|
||||
explicitly set.
|
||||
|
||||
``+[no]edns[=#]``
|
||||
This option specifies the EDNS version to query with. Valid values are 0 to 255.
|
||||
Setting the EDNS version causes an EDNS query to be sent.
|
||||
``+noedns`` clears the remembered EDNS version. EDNS is set to 0 by
|
||||
default.
|
||||
|
||||
``+[no]ednsflags[=#]``
|
||||
This option sets the must-be-zero EDNS flags bits (Z bits) to the specified value.
|
||||
Decimal, hex, and octal encodings are accepted. Setting a named flag
|
||||
(e.g., DO) is silently ignored. By default, no Z bits are set.
|
||||
|
||||
``+[no]ednsnegotiation``
|
||||
This option enables/disables EDNS version negotiation. By default, EDNS version
|
||||
negotiation is enabled.
|
||||
|
||||
``+[no]ednsopt[=code[:value]]``
|
||||
This option specifies the EDNS option with code point ``code`` and an optional payload
|
||||
of ``value`` as a hexadecimal string. ``code`` can be either an EDNS
|
||||
option name (for example, ``NSID`` or ``ECS``) or an arbitrary
|
||||
numeric value. ``+noednsopt`` clears the EDNS options to be sent.
|
||||
|
||||
``+[no]expire``
|
||||
This option sends an EDNS Expire option.
|
||||
|
||||
``+[no]fail``
|
||||
This option indicates that ``named`` should try [or not try] the next server if a SERVFAIL is received. The default is
|
||||
to not try the next server, which is the reverse of normal stub
|
||||
resolver behavior.
|
||||
|
||||
``+[no]header-only``
|
||||
This option sends a query with a DNS header without a question section. The
|
||||
default is to add a question section. The query type and query name
|
||||
are ignored when this is set.
|
||||
|
||||
``+[no]https[=value]``
|
||||
This option indicates whether to use DNS-over-HTTPS (DoH) when querying
|
||||
name servers. When this option is in use, the port number defaults to 443.
|
||||
The HTTP POST request mode is used when sending the query.
|
||||
|
||||
If ``value`` is specified, it will be used as the HTTP endpoint in the
|
||||
query URI; the default is ``/dns-query``. So, for example, ``dig
|
||||
@example.com +https`` will use the URI ``https://example.com/dns-query``.
|
||||
|
||||
``+[no]https-get[=value]``
|
||||
Similar to ``+https``, except that the HTTP GET request mode is used
|
||||
when sending the query.
|
||||
|
||||
``+[no]https-post[=value]``
|
||||
Same as ``+https``.
|
||||
|
||||
``+[no]http-plain[=value]``
|
||||
Similar to ``+https``, except that HTTP queries will be sent over a
|
||||
non-encrypted channel. When this option is in use, the port number
|
||||
defaults to 80 and the HTTP request mode is POST.
|
||||
|
||||
``+[no]http-plain-get[=value]``
|
||||
Similar to ``+http-plain``, except that the HTTP request mode is GET.
|
||||
|
||||
``+[no]http-plain-post[=value]``
|
||||
Same as ``+http-plain``.
|
||||
|
||||
``+[no]identify``
|
||||
This option shows [or does not show] the IP address and port number that
|
||||
supplied the answer, when the ``+short`` 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.
|
||||
|
||||
``+[no]idnin``
|
||||
This option processes [or does not process] IDN domain names on input. This requires
|
||||
``IDN SUPPORT`` to have been enabled at compile time.
|
||||
|
||||
The default is to process IDN input when standard output is a tty.
|
||||
The IDN processing on input is disabled when ``dig`` output is redirected
|
||||
to files, pipes, and other non-tty file descriptors.
|
||||
|
||||
``+[no]idnout``
|
||||
This option converts [or does not convert] puny code on output. This requires
|
||||
``IDN SUPPORT`` to have been enabled at compile time.
|
||||
|
||||
The default is to process puny code on output when standard output is
|
||||
a tty. The puny code processing on output is disabled when ``dig`` output
|
||||
is redirected to files, pipes, and other non-tty file descriptors.
|
||||
|
||||
``+[no]ignore``
|
||||
This option ignores [or does not ignore] truncation in UDP responses instead of retrying with TCP. By
|
||||
default, TCP retries are performed.
|
||||
|
||||
``+[no]keepalive``
|
||||
This option sends [or does not send] an EDNS Keepalive option.
|
||||
|
||||
``+[no]keepopen``
|
||||
This option keeps [or does not keep] the TCP socket open between queries, and reuses it rather than
|
||||
creating a new TCP socket for each lookup. The default is
|
||||
``+nokeepopen``.
|
||||
|
||||
``+[no]mapped``
|
||||
This option allows [or does not allow] mapped IPv4-over-IPv6 addresses to be used. The default is
|
||||
``+mapped``.
|
||||
|
||||
``+[no]multiline``
|
||||
This option prints [or does not 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 ``dig`` output.
|
||||
|
||||
``+ndots=D``
|
||||
This option sets the number of dots (``D``) that must appear in ``name`` for
|
||||
it to be considered absolute. The default value is that defined using
|
||||
the ``ndots`` statement in ``/etc/resolv.conf``, or 1 if no ``ndots``
|
||||
statement is present. Names with fewer dots are interpreted as
|
||||
relative names, and are searched for in the domains listed in the
|
||||
``search`` or ``domain`` directive in ``/etc/resolv.conf`` if
|
||||
``+search`` is set.
|
||||
|
||||
``+[no]nsid``
|
||||
When enabled, this option includes an EDNS name server ID request when sending a query.
|
||||
|
||||
``+[no]nssearch``
|
||||
When this option is set, ``dig`` 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.
|
||||
Addresses of servers that did not respond are also printed.
|
||||
|
||||
``+[no]onesoa``
|
||||
When enabled, this option prints only one (starting) SOA record when performing an AXFR. The
|
||||
default is to print both the starting and ending SOA records.
|
||||
|
||||
``+[no]opcode=value``
|
||||
When enabled, this option sets (restores) the DNS message opcode to the specified value. The
|
||||
default value is QUERY (0).
|
||||
|
||||
``+padding=value``
|
||||
This option pads the size of the query packet using the EDNS Padding option to
|
||||
blocks of ``value`` bytes. For example, ``+padding=32`` causes a
|
||||
48-byte query to be padded to 64 bytes. The default block size is 0,
|
||||
which disables padding; the maximum is 512. Values are ordinarily
|
||||
expected to be powers of two, such as 128; however, this is not
|
||||
mandatory. Responses to padded queries may also be padded, but only
|
||||
if the query uses TCP or DNS COOKIE.
|
||||
|
||||
``+qid=value``
|
||||
This option specifies the query ID to use when sending queries.
|
||||
|
||||
``+[no]qr``
|
||||
This option toggles the display of the query message as it is sent. By default, the query
|
||||
is not printed.
|
||||
|
||||
``+[no]question``
|
||||
This option toggles the display of the question section of a query when an answer is
|
||||
returned. The default is to print the question section as a comment.
|
||||
|
||||
``+[no]raflag``
|
||||
This option sets [or does not set] the RA (Recursion Available) bit in the query. The
|
||||
default is ``+noraflag``. This bit is ignored by the server for
|
||||
QUERY.
|
||||
|
||||
``+[no]rdflag``
|
||||
This option is a synonym for ``+[no]recurse``.
|
||||
|
||||
``+[no]recurse``
|
||||
This option toggles the setting of the RD (recursion desired) bit in the query.
|
||||
This bit is set by default, which means ``dig`` normally sends
|
||||
recursive queries. Recursion is automatically disabled when the
|
||||
``+nssearch`` or ``+trace`` query option is used.
|
||||
|
||||
``+retry=T``
|
||||
This option sets the number of times to retry UDP and TCP queries to server to ``T``
|
||||
instead of the default, 2. Unlike ``+tries``, this does not include
|
||||
the initial query.
|
||||
|
||||
``+[no]rrcomments``
|
||||
This option toggles the display of per-record comments in the output (for example,
|
||||
human-readable key information about DNSKEY records). The default is
|
||||
not to print record comments unless multiline mode is active.
|
||||
|
||||
``+[no]search``
|
||||
This option uses [or does not use] the search list defined by the searchlist or domain
|
||||
directive in ``resolv.conf``, if any. The search list is not used by
|
||||
default.
|
||||
|
||||
``ndots`` from ``resolv.conf`` (default 1), which may be overridden by
|
||||
``+ndots``, determines whether the name is treated as relative
|
||||
and hence whether a search is eventually performed.
|
||||
|
||||
``+[no]short``
|
||||
This option toggles whether a terse answer is provided. The default is to print the answer in a verbose
|
||||
form. This option always has a global effect; it cannot be set globally and
|
||||
then overridden on a per-lookup basis.
|
||||
|
||||
``+[no]showbadcookie``
|
||||
This option toggles whether to show the message containing the
|
||||
BADCOOKIE rcode before retrying the request or not. The default
|
||||
is to not show the messages.
|
||||
|
||||
``+[no]showsearch``
|
||||
This option performs [or does not perform] a search showing intermediate results.
|
||||
|
||||
``+[no]sigchase``
|
||||
This feature is now obsolete and has been removed; use ``delv``
|
||||
instead.
|
||||
|
||||
``+split=W``
|
||||
This option splits long hex- or base64-formatted fields in resource records into
|
||||
chunks of ``W`` characters (where ``W`` is rounded up to the nearest
|
||||
multiple of 4). ``+nosplit`` or ``+split=0`` causes fields not to be
|
||||
split at all. The default is 56 characters, or 44 characters when
|
||||
multiline mode is active.
|
||||
|
||||
``+[no]stats``
|
||||
This option toggles the printing of statistics: when the query was made, the size of the
|
||||
reply, etc. The default behavior is to print the query statistics as a
|
||||
comment after each lookup.
|
||||
|
||||
``+[no]subnet=addr[/prefix-length]``
|
||||
This option sends [or does not send] an EDNS CLIENT-SUBNET option with the specified IP
|
||||
address or network prefix.
|
||||
|
||||
``dig +subnet=0.0.0.0/0``, or simply ``dig +subnet=0`` for short,
|
||||
sends an EDNS CLIENT-SUBNET option with an empty address and a source
|
||||
prefix-length of zero, which signals a resolver that the client's
|
||||
address information must *not* be used when resolving this query.
|
||||
|
||||
``+[no]tcflag``
|
||||
This option sets [or does not set] the TC (TrunCation) bit in the query. The default is
|
||||
``+notcflag``. This bit is ignored by the server for QUERY.
|
||||
|
||||
``+[no]tcp``
|
||||
This option indicates whether to use TCP when querying name servers.
|
||||
The default behavior is to use UDP unless a type ``any`` or ``ixfr=N``
|
||||
query is requested, in which case the default is TCP. AXFR queries
|
||||
always use TCP.
|
||||
|
||||
``+timeout=T``
|
||||
This option sets the timeout for a query to ``T`` seconds. The default timeout is
|
||||
5 seconds. An attempt to set ``T`` to less than 1 is silently set to 1.
|
||||
|
||||
``+[no]tls``
|
||||
This option indicates whether to use DNS-over-TLS (DoT) when querying
|
||||
name servers. When this option is in use, the port number defaults
|
||||
to 853.
|
||||
|
||||
``+[no]topdown``
|
||||
This feature is related to ``dig +sigchase``, which is obsolete and
|
||||
has been removed. Use ``delv`` instead.
|
||||
|
||||
``+[no]trace``
|
||||
This option toggles 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, ``dig`` makes iterative queries to resolve the
|
||||
name being looked up. It follows referrals from the root servers,
|
||||
showing the answer from each server that was used to resolve the
|
||||
lookup.
|
||||
|
||||
If ``@server`` is also specified, it affects only the initial query for
|
||||
the root zone name servers.
|
||||
|
||||
``+dnssec`` is also set when ``+trace`` is set, to better emulate the
|
||||
default queries from a name server.
|
||||
|
||||
``+tries=T``
|
||||
This option sets the number of times to try UDP and TCP queries to server to ``T``
|
||||
instead of the default, 3. If ``T`` is less than or equal to zero,
|
||||
the number of tries is silently rounded up to 1.
|
||||
|
||||
``+trusted-key=####``
|
||||
This option formerly specified trusted keys for use with ``dig +sigchase``. This
|
||||
feature is now obsolete and has been removed; use ``delv`` instead.
|
||||
|
||||
``+[no]ttlid``
|
||||
This option displays [or does not display] the TTL when printing the record.
|
||||
|
||||
``+[no]ttlunits``
|
||||
This option displays [or does not display] the TTL in friendly human-readable time
|
||||
units of ``s``, ``m``, ``h``, ``d``, and ``w``, representing seconds, minutes,
|
||||
hours, days, and weeks. This implies ``+ttlid``.
|
||||
|
||||
``+[no]unknownformat``
|
||||
This option prints all RDATA in unknown RR type presentation format (:rfc:`3597`).
|
||||
The default is to print RDATA for known types in the type's
|
||||
presentation format.
|
||||
|
||||
``+[no]vc``
|
||||
This option uses [or does not use] TCP when querying name servers. This alternate
|
||||
syntax to ``+[no]tcp`` is provided for backwards compatibility. The
|
||||
``vc`` stands for "virtual circuit."
|
||||
|
||||
``+[no]yaml``
|
||||
When enabled, this option prints the responses (and, if ``+qr`` is in use, also the
|
||||
outgoing queries) in a detailed YAML format.
|
||||
|
||||
``+[no]zflag``
|
||||
This option sets [or does not set] the last unassigned DNS header flag in a DNS query.
|
||||
This flag is off by default.
|
||||
|
||||
Multiple Queries
|
||||
~~~~~~~~~~~~~~~~
|
||||
|
||||
The BIND 9 implementation of ``dig`` supports specifying multiple
|
||||
queries on the command line (in addition to supporting the ``-f`` batch
|
||||
file option). Each of those queries can be supplied with its own set of
|
||||
flags, options, and query options.
|
||||
|
||||
In this case, each ``query`` argument represents 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.
|
||||
|
||||
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 ``+[no]cmd`` and
|
||||
``+[no]short`` options) can be overridden by a query-specific set of
|
||||
query options. For example:
|
||||
|
||||
::
|
||||
|
||||
dig +qr www.isc.org any -x 127.0.0.1 isc.org ns +noqr
|
||||
|
||||
shows how ``dig`` can 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
|
||||
``+qr`` is applied, so that ``dig`` shows the initial query it made for
|
||||
each lookup. The final query has a local query option of ``+noqr`` which
|
||||
means that ``dig`` does not print the initial query when it looks up the
|
||||
NS records for ``isc.org``.
|
||||
|
||||
IDN Support
|
||||
~~~~~~~~~~~
|
||||
|
||||
If ``dig`` has been built with IDN (internationalized domain name)
|
||||
support, it can accept and display non-ASCII domain names. ``dig``
|
||||
appropriately converts character encoding of a domain name before sending
|
||||
a request to a DNS server or displaying a reply from the server.
|
||||
To turn off IDN support, use the parameters
|
||||
``+noidnin`` and ``+noidnout``, or define the ``IDN_DISABLE`` environment
|
||||
variable.
|
||||
|
||||
Return Codes
|
||||
~~~~~~~~~~~~
|
||||
|
||||
``dig`` return codes are:
|
||||
|
||||
``0``
|
||||
DNS response received, including NXDOMAIN status
|
||||
|
||||
``1``
|
||||
Usage error
|
||||
|
||||
``8``
|
||||
Couldn't open batch file
|
||||
|
||||
``9``
|
||||
No reply from server
|
||||
|
||||
``10``
|
||||
Internal error
|
||||
|
||||
Files
|
||||
~~~~~
|
||||
|
||||
``/etc/resolv.conf``
|
||||
|
||||
``${HOME}/.digrc``
|
||||
|
||||

.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
|

/etc/resolv\&.conf\&.

to mimic the behavior of a name server by making non\-recursive queries and expecting to receive answers to those queries that can be referrals to other name servers\&.

argument can be any recognized query type: CNAME, NS, SOA, TXT, DNSKEY, AXFR, etc\&.
|

.sp
|

When no query type is specified,

\fBhost\fR

automatically selects an appropriate query type\&. By default, it looks for A, AAAA, and MX records\&. If the

option is given, queries will be made for SOA records\&. If

\fIname\fR

Synopsis
|
||||
~~~~~~~~
|
||||
|
||||
:program:`host` [**-aACdlnrsTUwv**] [**-c** class] [**-N** ndots] [**-p** port] [**-R** number] [**-t** type] [**-W** wait] [**-m** flag] [ [**-4**] | [**-6**] ] [**-v**] [**-V**] {name} [server]
|

|
||||
Description
|
||||
~~~~~~~~~~~
|
||||
|
||||
``host`` 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, ``host`` prints a short summary of its
|
||||
command-line arguments and options.
|
||||
|
||||
``name`` 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 ``host`` by default performs a reverse lookup for that address.
|
||||
``server`` is an optional argument which is either the name or IP
|
||||
address of the name server that ``host`` should query instead of the
|
||||
server or servers listed in ``/etc/resolv.conf``.
|
||||
|
||||
Options
|
||||
~~~~~~~
|
||||
|
||||
``-4``
|
||||
This option specifies that only IPv4 should be used for query transport. See also the ``-6`` option.
|
||||
|
||||
``-6``
|
||||
This option specifies that only IPv6 should be used for query transport. See also the ``-4`` option.
|
||||
|
||||
``-a``
|
||||
The ``-a`` ("all") option is normally equivalent to ``-v -t ANY``. It
|
||||
also affects the behavior of the ``-l`` list zone option.
|
||||
|
||||
``-A``
|
||||
The ``-A`` ("almost all") option is equivalent to ``-a``, except that RRSIG,
|
||||
NSEC, and NSEC3 records are omitted from the output.
|
||||
|
||||
``-c class``
|
||||
This option specifies the query class, which can be used to lookup HS (Hesiod) or CH (Chaosnet)
|
||||
class resource records. The default class is IN (Internet).
|
||||
|
||||
``-C``
|
||||
This option indicates that ``named`` should check consistency, meaning that ``host`` queries the SOA records for zone
|
||||
``name`` 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.
|
||||
|
||||
``-d``
|
||||
This option prints debugging traces, and is equivalent to the ``-v`` verbose option.
|
||||
|
||||
``-l``
|
||||
This option tells ``named` to list the zone, meaning the ``host`` command performs a zone transfer of zone
|
||||
``name`` and prints out the NS, PTR, and address records (A/AAAA).
|
||||
|
||||
Together, the ``-l -a`` options print all records in the zone.
|
||||
|
||||
``-N ndots``
|
||||
This option specifies the number of dots (``ndots``) that have to be in ``name`` for it to be
|
||||
considered absolute. The default value is that defined using the
|
||||
``ndots`` statement in ``/etc/resolv.conf``, or 1 if no ``ndots`` statement
|
||||
is present. Names with fewer dots are interpreted as relative names,
|
||||
and are searched for in the domains listed in the ``search`` or
|
||||
``domain`` directive in ``/etc/resolv.conf``.
|
||||
|
||||
``-p port``
|
||||
This option specifies the port to query on the server. The default is 53.
|
||||
|
||||
``-r``
|
||||
This option specifies a non-recursive query; setting this option clears the RD (recursion
|
||||
desired) bit in the query. This means that the name server
|
||||
receiving the query does not attempt to resolve ``name``. The ``-r``
|
||||
option enables ``host`` to mimic the behavior of a name server by
|
||||
making non-recursive queries, and expecting to receive answers to
|
||||
those queries that can be referrals to other name servers.
|
||||
|
||||
``-R number``
|
||||
This option specifies the number of retries for UDP queries. If ``number`` is negative or zero,
|
||||
the number of retries is silently set to 1. The default value is 1, or
|
||||
the value of the ``attempts`` option in ``/etc/resolv.conf``, if set.
|
||||
|
||||
``-s``
|
||||
This option tells ``named`` *not* to send the query to the next nameserver if any server responds
|
||||
with a SERVFAIL response, which is the reverse of normal stub
|
||||
resolver behavior.
|
||||
|
||||
``-t type``
|
||||
This option specifies the query type. The ``type`` argument can be any recognized query type:
|
||||
CNAME, NS, SOA, TXT, DNSKEY, AXFR, etc.
|
||||
|
||||
When no query type is specified, ``host`` automatically selects an
|
||||
appropriate query type. By default, it looks for A, AAAA, and MX
|
||||
records. If the ``-C`` option is given, queries are made for SOA
|
||||
records. If ``name`` is a dotted-decimal IPv4 address or
|
||||
colon-delimited IPv6 address, ``host`` queries for PTR records.
|
||||
|
||||
If a query type of IXFR is chosen, the starting serial number can be
|
||||
specified by appending an equals sign (=), followed by the starting serial
|
||||
number, e.g., ``-t IXFR=12345678``.
|
||||
|
||||
``-T``; ``-U``
|
||||
This option specifies TCP or UDP. By default, ``host`` uses UDP when making queries; the
|
||||
``-T`` option makes it use a TCP connection when querying the name
|
||||
server. TCP is automatically selected for queries that require
|
||||
it, such as zone transfer (AXFR) requests. Type ``ANY`` queries default
|
||||
to TCP, but can be forced to use UDP initially via ``-U``.
|
||||
|
||||
``-m flag``
|
||||
This option sets memory usage debugging: the flag can be ``record``, ``usage``, or
|
||||
``trace``. The ``-m`` option can be specified more than once to set
|
||||
multiple flags.
|
||||
|
||||
``-v``
|
||||
This option sets verbose output, and is equivalent to the ``-d`` debug option. Verbose output
|
||||
can also be enabled by setting the ``debug`` option in
|
||||
``/etc/resolv.conf``.
|
||||
|
||||
``-V``
|
||||
This option prints the version number and exits.
|
||||
|
||||
``-w``
|
||||
This option sets "wait forever": the query timeout is set to the maximum possible. See
|
||||
also the ``-W`` option.
|
||||
|
||||
``-W wait``
|
||||
This options sets the length of the wait timeout, indicating that ``named`` should wait for up to ``wait`` seconds for a reply. If ``wait`` is
|
||||
less than 1, the wait interval is set to 1 second.
|
||||
|
||||
By default, ``host`` waits for 5 seconds for UDP responses and 10
|
||||
seconds for TCP connections. These defaults can be overridden by the
|
||||
``timeout`` option in ``/etc/resolv.conf``.
|
||||
|
||||
See also the ``-w`` option.
|
||||
|
||||
IDN Support
|
||||
~~~~~~~~~~~
|
||||
|
||||
If ``host`` has been built with IDN (internationalized domain name)
|
||||
support, it can accept and display non-ASCII domain names. ``host``
|
||||
appropriately converts character encoding of a domain name before sending
|
||||
a request to a DNS server or displaying a reply from the server.
|
||||
To turn off IDN support, define the ``IDN_DISABLE``
|
||||
environment variable. IDN support is disabled if the variable is set
|
||||
when ``host`` runs.

.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:
|
||||
.sp
|
||||
.RS 4
|
||||
.ie n \{\
|
||||
\h'-04' 1.\h'+01'\c
|
||||
.\}
|
||||
.el \{\
|
||||
.sp -1
|
||||
.IP " 1." 4.2
|
||||
.\}
|
||||
when no arguments are given (the default name server will be used)
|
||||
.RE
|
||||
.sp
|
||||
.RS 4
|
||||
.ie n \{\
|
||||
\h'-04' 2.\h'+01'\c
|
||||
.\}
|
||||
.el \{\
|
||||
.sp -1
|
||||
.IP " 2." 4.2
|
||||
.\}
|
||||
when the first argument is a hyphen (\-) and the second argument is the host name or Internet address of a name server\&.
|
||||
.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
|
||||
.if n \{\
|
||||
.RS 4
|
||||
.\}
|
||||
.nf
|
||||
nslookup \-query=hinfo \-timeout=10
|
||||
.fi
|
||||
.if n \{\
|
||||
.RE
|
||||
.\}
|

.PP
|
||||
The
|
||||
\fB\-version\fR
|
||||
option causes
|
||||
\fBnslookup\fR
|
||||
to print the version number and immediately exits\&.
|

.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\&.

|

|

<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>

</refsection>
|
||||
|
||||
<refsection><info><title>ARGUMENTS</title></info>
|
||||
|
||||
<para>
|
||||
Interactive mode is entered in the following cases:
|
||||
<orderedlist numeration="loweralpha" inheritnum="ignore" continuation="restarts">
|
||||
<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> produces bad nroff. -->
|
||||
<programlisting>
|
||||
nslookup -query=hinfo -timeout=10
|
||||
</programlisting>
|
||||
<!-- </informalexample> -->
|
||||
</para>
|
||||
<para>
|
||||
The <option>-version</option> option causes
|
||||
<command>nslookup</command> to print the version
|
||||
number and immediately exits.

If <command>nslookup</command> has been built with IDN (internationalized

<command>nslookup</command> appropriately converts character encoding of

domain name before sending a request to DNS server or displaying a

If you'd like to turn off the IDN support for some reason, define

the <envar>IDN_DISABLE</envar> environment variable.

The IDN support is disabled if the variable is set when

|
||||
|
||||
<p><span class="command"><strong>Nslookup</strong></span>
|
||||
is a program to query Internet domain name servers. <span class="command"><strong>Nslookup</strong></span>
|
||||
has two modes: interactive and non-interactive. Interactive mode allows
|
||||
the user to query name servers for information about various hosts and
|
||||
domains or to print a list of hosts in a domain. Non-interactive mode
|
||||
is
|
||||
used to print just the name and requested information for a host or
|
||||
domain.
|
||||
</p>
|
||||
</div>
|
||||
|
||||
<div class="refsection">
|
||||
<a name="id-1.8"></a><h2>ARGUMENTS</h2>
|
||||
|
||||
<p>
|
||||
Interactive mode is entered in the following cases:
|
||||
</p>
|
||||
<div class="orderedlist"><ol class="orderedlist" type="a">
|
||||
<li class="listitem">
|
||||
<p>
|
||||
when no arguments are given (the default name server will be used)
|
||||
</p>
|
||||
</li>
|
||||
<li class="listitem">
|
||||
<p>
|
||||
when the first argument is a hyphen (-) and the second argument is
|
||||
the host name or Internet address of a name server.
|
||||
</p>
|
||||
</li>
|
||||
</ol></div>
|
||||
<p>
|
||||
</p>
|
||||
|
||||
<p>
|
||||
Non-interactive mode is used when the name or Internet address of the
|
||||
host to be looked up is given as the first argument. The optional second
|
||||
argument specifies the host name or address of a name server.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
Options can also be specified on the command line if they precede the
|
||||
arguments and are prefixed with a hyphen. For example, to
|
||||
change the default query type to host information, and the initial
|
||||
timeout to 10 seconds, type:
|
||||
|
||||
</p>
|
||||
<pre class="programlisting">
|
||||
nslookup -query=hinfo -timeout=10
|
||||
</pre>
|
||||
<p>
|
||||
|
||||
</p>
|
||||
<p>
|
||||
The <code class="option">-version</code> option causes
|
||||
<span class="command"><strong>nslookup</strong></span> to print the version
|
||||
number and immediately exits.
|
||||

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.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
To look up a host not in the current domain, append a period to
|
||||
the name.

|

nslookup - query Internet name servers interactively
|
||||
----------------------------------------------------
|
||||
|
||||
Synopsis
|
||||
~~~~~~~~
|
||||
|
||||
:program:`nslookup` [-option] [name | -] [server]
|
||||
|
||||
Description
|
||||
~~~~~~~~~~~
|
||||
|
||||
``nslookup`` is a program to query Internet domain name servers.
|
||||
``nslookup`` 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 prints just the name and requested
|
||||
information for a host or domain.
|
||||
|
||||
Arguments
|
||||
~~~~~~~~~
|
||||
|
||||
Interactive mode is entered in the following cases:
|
||||
|
||||
a. when no arguments are given (the default name server is used);
|
||||
|
||||
b. when the first argument is a hyphen (-) and the second argument is
|
||||
the host name or Internet address of a name server.
|
||||
|
||||
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.
|
||||
|
||||
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, with an initial timeout of 10
|
||||
seconds, type:
|
||||
|
||||
::
|
||||
|
||||
nslookup -query=hinfo -timeout=10
|
||||
|
||||
The ``-version`` option causes ``nslookup`` to print the version number
|
||||
and immediately exit.
|
||||
|
||||
Interactive Commands
|
||||
~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
``host [server]``
|
||||
This command looks 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.
|
||||
|
||||
To look up a host not in the current domain, append a period to the
|
||||
name.
|
||||
|
||||
``server domain`` | ``lserver domain``
|
||||
These commands change the default server to ``domain``; ``lserver`` uses the initial
|
||||
server to look up information about ``domain``, while ``server`` uses the
|
||||
current default server. If an authoritative answer cannot be found,
|
||||
the names of servers that might have the answer are returned.
|
||||
|
||||
``root``
|
||||
This command is not implemented.
|
||||
|
||||
``finger``

|
||||
|
||||

|
||||
search list to the request until an answer is received. The default is ``search``.
|
||||
|
||||
``port=value``
|
||||

its default, port 53. The abbreviation for this keyword is ``po``.
|
||||
|
||||
``querytype=value`` | ``type=value``
|
||||
This keyword changes the type of the information query to ``value``. The

||||
defaults are A and then AAAA; the abbreviations for these keywords are
|
||||
``q`` and ``ty``.
|
||||

||||
behavior looks up both when an alternative is not specified.
|
||||
|
||||
``norecurse``
|
||||
This keyword tells the name server to query other servers if it does not have
|
||||
the information. The default is ``recurse``; the abbreviation for this
|
||||
keyword is ``[no]rec``.
|
||||
|
||||
``ndots=number``
|
||||
This keyword sets the number of dots (label separators) in a domain that
|
||||
disables searching. Absolute names always stop searching.

|
||||
``novc`` is the default.
|
||||
|
||||
``nofail``
|

|
||||
a referral (nofail), or terminates the query (fail) on such a response. The
|
||||
default is ``nofail``.
|
||||
|
||||
Return Values
|
||||
~~~~~~~~~~~~~
|
||||
|
||||
``nslookup`` returns with an exit status of 1 if any query failed, and 0
|
||||
otherwise.
|
||||
|
||||
IDN Support
|
||||
~~~~~~~~~~~
|
||||
|
||||
If ``nslookup`` has been built with IDN (internationalized domain name)
|
||||
support, it can accept and display non-ASCII domain names. ``nslookup``
|
||||
appropriately converts character encoding of a domain name before sending
|
||||
a request to a DNS server or displaying a reply from the server.
|
||||
To turn off IDN support, define the ``IDN_DISABLE``
|
||||
environment variable. IDN support is disabled if the variable is set
|
||||
when ``nslookup`` runs, or when the standard output is not a tty.
