037f4c44a9ef4e458f46b264aebd12df049b0f0cvboxsync<p><span><strong class="command">named-checkzone</strong></span>
037f4c44a9ef4e458f46b264aebd12df049b0f0cvboxsync checks the syntax and integrity of a zone file. It performs the
037f4c44a9ef4e458f46b264aebd12df049b0f0cvboxsync same checks as <span><strong class="command">named</strong></span> does when loading a
037f4c44a9ef4e458f46b264aebd12df049b0f0cvboxsync zone. This makes <span><strong class="command">named-checkzone</strong></span> useful for
037f4c44a9ef4e458f46b264aebd12df049b0f0cvboxsync checking zone files before configuring them into a name server.

8d974ced0dc3540dd1b3ec85f8663388e246461avboxsync <span><strong class="command">named-compilezone</strong></span> is similar to
8d974ced0dc3540dd1b3ec85f8663388e246461avboxsync <span><strong class="command">named-checkzone</strong></span>, but it always dumps the
8d974ced0dc3540dd1b3ec85f8663388e246461avboxsync zone contents to a specified file in a specified format.
8d974ced0dc3540dd1b3ec85f8663388e246461avboxsync Additionally, it applies stricter check levels by default,
8d974ced0dc3540dd1b3ec85f8663388e246461avboxsync since the dump output will be used as an actual zone file
8d974ced0dc3540dd1b3ec85f8663388e246461avboxsync loaded by <span><strong class="command">named</strong></span>.
8d974ced0dc3540dd1b3ec85f8663388e246461avboxsync When manually specified otherwise, the check levels must at
8d974ced0dc3540dd1b3ec85f8663388e246461avboxsync least be as strict as those specified in the
8d974ced0dc3540dd1b3ec85f8663388e246461avboxsync <span><strong class="command">named</strong></span> configuration file.

</p></dd>
<dt><span class="term">-F <em class="replaceable"><code>format</code></em></span></dt>
<dd>
<p>
Specify the format of the output file specified.
For <span><strong class="command">named-checkzone</strong></span>,
this does not cause any effects unless it dumps the zone
contents.
</p>
<p>
Possible formats are <span><strong class="command">"text"</strong></span> (default),
which is the standard textual representation of the zone,
and <span><strong class="command">"map"</strong></span>, <span><strong class="command">"raw"</strong></span>,
and <span><strong class="command">"raw=N"</strong></span>, which store the zone in a
binary format for rapid loading by <span><strong class="command">named</strong></span>.
<span><strong class="command">"raw=N"</strong></span> specifies the format version of
the raw zone file: if N is 0, the raw file can be read by
any version of <span><strong class="command">named</strong></span>; if N is 1, the file
can be read by release 9.9.0 or higher; the default is 1.
</p>

Perform <span><strong class="command">"check-names"</strong></span> checks with the

When compiling a zone to "raw" or "map" format, set the

number. (This is expected to be used primarily for testing
purposes.)
</p></dd>
<dt><span class="term">-m <em class="replaceable"><code>mode</code></em></span></dt>

write to standard out.
This is mandatory for <span><strong class="command">named-compilezone</strong></span>.
</p></dd>
<dt><span class="term">-r <em class="replaceable"><code>mode</code></em></span></dt>
<dd><p>
Check for records that are treated as different by DNSSEC but
are semantically equal in plain DNS.
Possible modes are <span><strong class="command">"fail"</strong></span>,
<span><strong class="command">"warn"</strong></span> (default) and
<span><strong class="command">"ignore"</strong></span>.
</p></dd>
<dt><span class="term">-s <em class="replaceable"><code>style</code></em></span></dt>
<dd><p>
Specify the style of the dumped zone file.
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.

chdir to <code class="filename">directory</code> so that
relative

</p></dd>
<dt><span class="term">-W <em class="replaceable"><code>mode</code></em></span></dt>
<dd><p>
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 <span><strong class="command">"warn"</strong></span> (default)
and
<span><strong class="command">"ignore"</strong></span>.
