1029N/A<
p><
span><
strong class="command">named-checkzone</
strong></
span>
1029N/A checks the syntax and integrity of a zone file. It performs the
1029N/A same checks as <
span><
strong class="command">named</
strong></
span> does when loading a
1029N/A zone. This makes <
span><
strong class="command">named-checkzone</
strong></
span> useful for
1123N/A checking zone files before configuring them into a name server.
1029N/A <
span><
strong class="command">named-compilezone</
strong></
span> is similar to
1106N/A <
span><
strong class="command">named-checkzone</
strong></
span>, but it always dumps the
1106N/A zone contents to a specified file in a specified format.
1110N/A Additionally, it applies stricter check levels by default,
1106N/A since the dump output will be used as an actual zone file
1029N/A loaded by <
span><
strong class="command">named</
strong></
span>.
1029N/A When manually specified otherwise, the check levels must at
1029N/A least be as strict as those specified in the
1029N/A <
span><
strong class="command">named</
strong></
span> configuration file.

1029N/A Perform post-load zone integrity checks. Possible modes are

span><
strong class="command">"full"</

span> (default),
1029N/A <
span><
strong class="command">"full-sibling"</

strong class="command">"local-sibling"</
strong></
span> and
1029N/A <
span><
strong class="command">"none"</
strong></
span>.
1029N/A Mode <
span><
strong class="command">"full"</
strong></
span> checks that MX records
1029N/A refer to A or AAAA record (both in-zone and out-of-zone
1029N/A hostnames). Mode <
span><
strong class="command">"local"</
strong></
span> only
1029N/A checks MX records which refer to in-zone hostnames.
1029N/A Mode <
span><
strong class="command">"full"</
strong></
span> checks that SRV records
1029N/A refer to A or AAAA record (both in-zone and out-of-zone
1029N/A hostnames). Mode <
span><
strong class="command">"local"</
strong></
span> only
1029N/A checks SRV records which refer to in-zone hostnames.
1029N/A Mode <
span><
strong class="command">"full"</
strong></
span> checks that delegation NS
1029N/A records refer to A or AAAA record (both in-zone and out-of-zone
1029N/A hostnames). It also checks that glue address records
1029N/A in the zone match those advertised by the child.
1029N/A Mode <
span><
strong class="command">"local"</
strong></
span> only checks NS records which
1029N/A refer to in-zone hostnames or that some required glue exists,
1029N/A that is when the nameserver is in a child zone.
1029N/A Mode <
span><
strong class="command">"full-sibling"</
strong></
span> and
1029N/A <
span><
strong class="command">"local-sibling"</
strong></

1029N/A checks but are otherwise the same as <

strong></

1029N/A and <

automatically by a separate script.

human-readable and is thus suitable for editing by hand.
