d868475ad62547f0a034dfaf038aff31b3d05372Zbigniew Jędrzejewski-Szmek<p><span><strong class="command">named-checkzone</strong></span>
d868475ad62547f0a034dfaf038aff31b3d05372Zbigniew Jędrzejewski-Szmek checks the syntax and integrity of a zone file. It performs the
847ae0ae7f29e7bfb245d692409fc2948eab7d1dLennart Poettering same checks as <span><strong class="command">named</strong></span> does when loading a
299a55075d1bf478b9190191caefd5c1b934340dMark Eichin zone. This makes <span><strong class="command">named-checkzone</strong></span> useful for
d868475ad62547f0a034dfaf038aff31b3d05372Zbigniew Jędrzejewski-Szmek checking zone files before configuring them into a name server.

299a55075d1bf478b9190191caefd5c1b934340dMark Eichin <span><strong class="command">named-compilezone</strong></span> is similar to
3fde5f30bda2a70d97f3dc8fa918e42e1c07cc2cLennart Poettering <span><strong class="command">named-checkzone</strong></span>, but it always dumps the
299a55075d1bf478b9190191caefd5c1b934340dMark Eichin zone contents to a specified file in a specified format.
3fde5f30bda2a70d97f3dc8fa918e42e1c07cc2cLennart Poettering Additionally, it applies stricter check levels by default,
3fde5f30bda2a70d97f3dc8fa918e42e1c07cc2cLennart Poettering since the dump output will be used as an actual zone file
3fde5f30bda2a70d97f3dc8fa918e42e1c07cc2cLennart Poettering loaded by <span><strong class="command">named</strong></span>.
847ae0ae7f29e7bfb245d692409fc2948eab7d1dLennart Poettering When manaully specified otherwise, the check levels must at
847ae0ae7f29e7bfb245d692409fc2948eab7d1dLennart Poettering least be as strict as those specified in the
847ae0ae7f29e7bfb245d692409fc2948eab7d1dLennart Poettering <span><strong class="command">named</strong></span> configuration file.

Possible modes are <span><strong class="command">"fail"</strong></span>
(default for <span><strong class="command">named-compilezone</strong></span>),
<span><strong class="command">"warn"</strong></span>
(default for <span><strong class="command">named-checkzone</strong></span>) and

Specify whether MX records should be checked to see if they
are addresses. 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">-M <em class="replaceable"><code>mode</code></em></span></dt>

Check if a MX record refers to a CNAME.
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>

Specify whether NS records should be checked to see if they
are addresses.
Possible modes are <span><strong class="command">"fail"</strong></span>
(default for <span><strong class="command">named-compilezone</strong></span>),
<span><strong class="command">"warn"</strong></span>
(default for <span><strong class="command">named-checkzone</strong></span>) and
<span><strong class="command">"ignore"</strong></span>.
</p></dd>
<dt><span class="term">-o <em class="replaceable"><code>filename</code></em></span></dt>
<dd><p>
Write zone output to <code class="filename">filename</code>.
This is mandatory for <span><strong class="command">named-compilezone</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.
</p></dd>

Check if a SRV record refers to a CNAME.
Possible modes are <span><strong class="command">"fail"</strong></span>,

chdir to <code class="filename">directory</code> so that
relative
filenames in master file $INCLUDE directives work. This
is similar to the directory clause in

Dump zone file in canonical format.

<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>.

The domain name of the zone being checked.
