|
||
<p><span><strong class="command">named-checkzone</strong></span>
|
||
checks the syntax and integrity of a zone file. It performs the
|
||
same checks as <span><strong class="command">named</strong></span> does when loading a
|
||
zone. This makes <span><strong class="command">named-checkzone</strong></span> useful for
|
||
checking zone files before configuring them into a name server.
|
||
</p>
|
||
<p>
|
||
<span><strong class="command">named-compilezone</strong></span> is similar to
|
||
<span><strong class="command">named-checkzone</strong></span>, 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 <span><strong class="command">named</strong></span>.
|
||
When manually specified otherwise, the check levels must at
|
||
least be as strict as those specified in the
|
||
<span><strong class="command">named</strong></span> configuration file.

Perform post-load zone integrity checks. Possible modes are
|

<span><strong class="command">"full"</strong></span> (default),

<span><strong class="command">"full-sibling"</strong></span>,
|
||
<span><strong class="command">"local"</strong></span>,

<span><strong class="command">"local-sibling"</strong></span> and

<span><strong class="command">"none"</strong></span>.
|
||
</p>
|
||
<p>
|
||
Mode <span><strong class="command">"full"</strong></span> checks that MX records
|
||
refer to A or AAAA record (both in-zone and out-of-zone
|

hostnames). Mode <span><strong class="command">"local"</strong></span> only
|
||
checks MX records which refer to in-zone hostnames.
|
||
</p>
|
||
<p>
|
||
Mode <span><strong class="command">"full"</strong></span> checks that SRV records
|
||
refer to A or AAAA record (both in-zone and out-of-zone
|
||
hostnames). Mode <span><strong class="command">"local"</strong></span> only
|
||
checks SRV records which refer to in-zone hostnames.
|
||
</p>
|
||
<p>
|
||
Mode <span><strong class="command">"full"</strong></span> 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 <span><strong class="command">"local"</strong></span> 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.

<p>

Mode <span><strong class="command">"full-sibling"</strong></span> and

<span><strong class="command">"local-sibling"</strong></span> disable sibling glue

checks but are otherwise the same as <span><strong class="command">"full"</strong></span>

</p>

Possible styles are <span><strong class="command">"full"</strong></span> (default)

and <span><strong class="command">"relative"</strong></span>.
|
||
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 <span><strong class="command">named-checkzone</strong></span>
|

this does not cause any effects unless it dumps the zone
|

contents.
|

It also does not have any meaning if the output format
