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.
