       named-checkzone [-d] [-h] [-j] [-q] [-v] [-c class] [-f format] [-F format] [-i mode] [-k mode] [-m mode] [-M mode] [-n mode] [-o filename]
		       [-r mode] [-s style] [-S mode] [-t directory] [-w directory] [-D] [-W mode] {zonename} {filename}

       named-compilezone [-d] [-j] [-q] [-v] [-c class] [-C mode] [-f format] [-F format] [-i mode] [-k mode] [-m mode] [-n mode] [-r mode]
			 [-s style] [-t directory] [-w directory] [-D] [-W mode] {-o filename} {zonename} {filename}

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.

       -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.

       -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.
