The ARM and the manpages have been converted into Sphinx documentation
format.
Sphinx uses reStructuredText as its markup language, and many of its
strengths come from the power and straightforwardness of
reStructuredText and its parsing and translating suite, the Docutils.

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.
|
|
Additionally, it applies stricter check levels by default, since the
|
|
dump output will be 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**
|
|
Enable debugging.
|
|
|
|
**-h**
|
|
Print the usage summary and exit.
|
|
|
|
**-q**
|
|
Quiet mode - exit code only.
|
|
|
|
**-v**
|
|
Print the version of the ``named-checkzone`` program and exit.
|
|
|
|
**-j**
|
|
When loading a zone file, read the journal if it exists. The journal
|
|
file name is assumed to be the zone file name appended with the
|
|
string ``.jnl``.
|
|
|
|
**-J** filename
|
|
When loading the zone file read the journal from the given file, if
|
|
it exists. (Implies -j.)
|
|
|
|
**-c** class
|
|
Specify the class of the zone. If not specified, "IN" is assumed.
|
|
|
|
**-i** mode
|
|
Perform post-load zone integrity checks. Possible modes are
|
|
``"full"`` (default), ``"full-sibling"``, ``"local"``,
|
|
``"local-sibling"`` and ``"none"``.
|
|
|
|
Mode ``"full"`` checks that MX records refer to A or AAAA record
|
|
(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 record
|
|
(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
|
|
record (both in-zone and out-of-zone hostnames). It also checks that
|
|
glue address records in the zone match those advertised by the child.
|
|
Mode ``"local"`` only checks NS records which refer to in-zone
|
|
hostnames or that some required glue exists, that is when the
|
|
nameserver is in a child zone.
|
|
|
|
Mode ``"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
|
|
Specify the format of the zone file. Possible formats are ``"text"``
|
|
(default), ``"raw"``, and ``"map"``.
|
|
|
|
**-F** format
|
|
Specify the format of the output file specified. For
|
|
``named-checkzone``, this does not cause any effects unless it dumps
|
|
the zone contents.
|
|
|
|
Possible formats are ``"text"`` (default), which is the standard
|
|
textual representation of the zone, and ``"map"``, ``"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 be read by release 9.9.0 or
|
|
higher; the default is 1.
|
|
|
|
**-k** mode
|
|
Perform ``"check-names"`` checks with the specified failure mode.
|
|
Possible modes are ``"fail"`` (default for ``named-compilezone``),
|
|
``"warn"`` (default for ``named-checkzone``) and ``"ignore"``.
|
|
|
|
**-l** ttl
|
|
Sets a maximum permissible TTL for the input file. Any record with a
|
|
TTL higher than this value will cause 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" or "map" format, set the "source
|
|
serial" value in the header to the specified serial number. (This is
|
|
expected to be used primarily for testing purposes.)
|
|
|
|
**-m** mode
|
|
Specify whether MX records should be checked to see if they are
|
|
addresses. Possible modes are ``"fail"``, ``"warn"`` (default) and
|
|
``"ignore"``.
|
|
|
|
**-M** mode
|
|
Check if a MX record refers to a CNAME. Possible modes are
|
|
``"fail"``, ``"warn"`` (default) and ``"ignore"``.
|
|
|
|
**-n** mode
|
|
Specify whether NS records should be checked to see if they are
|
|
addresses. Possible modes are ``"fail"`` (default for
|
|
``named-compilezone``), ``"warn"`` (default for ``named-checkzone``)
|
|
and ``"ignore"``.
|
|
|
|
**-o** filename
|
|
Write zone output to ``filename``. If ``filename`` is ``-`` then
|
|
write to standard out. This is mandatory for ``named-compilezone``.
|
|
|
|
**-r** mode
|
|
Check for records that are treated as different by DNSSEC but are
|
|
semantically equal in plain DNS. Possible modes are ``"fail"``,
|
|
``"warn"`` (default) and ``"ignore"``.
|
|
|
|
**-s** style
|
|
Specify the style of the dumped zone file. Possible styles are
|
|
``"full"`` (default) and ``"relative"``. The full format is most
|
|
suitable for processing automatically by a separate script. On the
|
|
other hand, the relative format is more human-readable and is thus
|
|
suitable for editing by hand. For ``named-checkzone`` this does not
|
|
cause any effects unless it dumps the zone contents. It also does not
|
|
have any meaning if the output format is not text.
|
|
|
|
**-S** mode
|
|
Check if a SRV record refers to a CNAME. Possible modes are
|
|
``"fail"``, ``"warn"`` (default) and ``"ignore"``.
|
|
|
|
**-t** directory
|
|
Chroot to ``directory`` so that include directives in the
|
|
configuration file are processed as if run by a similarly chrooted
|
|
``named``.
|
|
|
|
**-T** mode
|
|
Check if Sender Policy Framework (SPF) records exist and issues a
|
|
warning if an SPF-formatted TXT record is not also present. Possible
|
|
modes are ``"warn"`` (default), ``"ignore"``.
|
|
|
|
**-w** directory
|
|
chdir to ``directory`` so that relative filenames in master file
|
|
$INCLUDE directives work. This is similar to the directory clause in
|
|
``named.conf``.
|
|
|
|
**-D**
|
|
Dump zone file in canonical format. This is always enabled for
|
|
``named-compilezone``.
|
|
|
|
**-W** mode
|
|
Specify whether to check for non-terminal wildcards. Non-terminal
|
|
wildcards are almost always the result of a failure to understand the
|
|
wildcard matching algorithm (:rfc:`1034`). Possible modes are ``"warn"``
|
|
(default) and ``"ignore"``.
|
|
|
|
zonename
|
|
The domain name of the zone being checked.
|
|
|
|
filename
|
|
The name of the zone file.
|
|
|
|
Return Values
|
|
~~~~~~~~~~~~~
|
|
|
|
``named-checkzone`` returns an exit status of 1 if errors were detected
|
|
and 0 otherwise.
