the problems related to the handling of broken DNSSEC trust chains. This fix is only relevant for those who have DNSSEC validation enabled and configure trust anchors from third parties, either manually, or through a system like DLV.

|
||
<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>
|

<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>
|

and <span><strong class="command">"local"</strong></span> respectively.
|

</p>
|

<p>

Mode <span><strong class="command">"none"</strong></span> disables the checks.

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
|
||
is not text.
