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 the zone file read the journal if it exists.

       -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) and "raw".

       -F format
           Specify the format of the output file specified. Possible formats
           are "text" (default) and "raw". For named-checkzone, this does not
           cause any effects unless it dumps the zone contents.

       -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".

       -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.

       -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.

       -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.
