2N/A<
p><
span><
strong class="command">named-checkzone</
strong></
span>
2N/A checks the syntax and integrity of a zone file. It performs the
2N/A same checks as <
span><
strong class="command">named</
strong></
span> does when loading a
2N/A zone. This makes <
span><
strong class="command">named-checkzone</
strong></
span> useful for
2N/A checking zone files before configuring them into a name server.
2N/A <
span><
strong class="command">named-compilezone</
strong></
span> is similar to
2N/A <
span><
strong class="command">named-checkzone</
strong></
span>, but it always dumps the
2N/A zone contents to a specified file in a specified format.
2N/A Additionally, it applies stricter check levels by default,
2N/A since the dump output will be used as an actual zone file
2N/A loaded by <
span><
strong class="command">named</
strong></
span>.
2N/A When manaully specified otherwise, the check levels must at
2N/A least be as strict as those specified in the
2N/A <
span><
strong class="command">named</
strong></
span> configuration file.

2N/A Perform post load zone integrity checks. Possible modes are
2N/A <
span><
strong class="command">"full"</
strong></
span> (default),
2N/A <
span><
strong class="command">"local"</
strong></
span> and
2N/A <
span><
strong class="command">"none"</
strong></
span>.
2N/A Mode <
span><
strong class="command">"full"</
strong></
span> checks that MX records
2N/A refer to A or AAAA record (both in-zone and out-of-zone
2N/A hostnames). Mode <
span><
strong class="command">"local"</
strong></
span> only
2N/A checks MX records which refer to in-zone hostnames.
2N/A Mode <
span><
strong class="command">"full"</
strong></
span> checks that SRV records
2N/A refer to A or AAAA record (both in-zone and out-of-zone
2N/A hostnames). Mode <
span><
strong class="command">"local"</
strong></
span> only
2N/A checks SRV records which refer to in-zone hostnames.
2N/A Mode <
span><
strong class="command">"full"</
strong></
span> checks that delegation NS
2N/A records refer to A or AAAA record (both in-zone and out-of-zone
2N/A hostnames). It also checks that glue addresses records
2N/A in the zone match those advertised by the child.
2N/A Mode <
span><
strong class="command">"local"</
strong></
span> only checks NS records which
2N/A refer to in-zone hostnames or that some required glue exists,
2N/A that is when the nameserver is in a child zone.
2N/A Mode <

strong class="command">"none"</

2N/A<

2N/A Possible styles are <
span><
strong class="command">"full"</
strong></
span> (default)
2N/A and <
span><
strong class="command">"default"</
strong></
span>.
2N/A The full format is most suitable for processing
2N/A automatically by a separate script.
2N/A On the other hand, the default format is more
2N/A human-readable and is thus suitable for editing by hand.
2N/A For <
span><
strong class="command">named-checkzone</

2N/A this does not cause any effects unless it dumps the zone
2N/A It also does not have any meaning if the output format

2N/A Specify whether to check for non-terminal wildcards.
2N/A Non-terminal wildcards are almost always the result of a
2N/A failure to understand the wildcard matching algorithm (RFC 1034).
2N/A Possible modes are <

2N/A <
