1cd8881c9c3a32110a49a6668919aa3750dc1285JazzyNico<p><span><strong class="command">named-checkzone</strong></span>
4e10d188042815c5285edf00ea96896b862e0863aurium checks the syntax and integrity of a zone file. It performs the
4e10d188042815c5285edf00ea96896b862e0863aurium same checks as <span><strong class="command">named</strong></span> does when loading a
4e10d188042815c5285edf00ea96896b862e0863aurium zone. This makes <span><strong class="command">named-checkzone</strong></span> useful for
4e10d188042815c5285edf00ea96896b862e0863aurium checking zone files before configuring them into a name server.
4e10d188042815c5285edf00ea96896b862e0863aurium </p>
1cd8881c9c3a32110a49a6668919aa3750dc1285JazzyNico<p>
4e10d188042815c5285edf00ea96896b862e0863aurium <span><strong class="command">named-compilezone</strong></span> is similar to
1cd8881c9c3a32110a49a6668919aa3750dc1285JazzyNico <span><strong class="command">named-checkzone</strong></span>, but it always dumps the
83aaf46c9feab529aeb9add871c05c3d1177afccaurium zone contents to a specified file in a specified format.
83aaf46c9feab529aeb9add871c05c3d1177afccaurium Additionally, it applies stricter check levels by default,
4e10d188042815c5285edf00ea96896b862e0863aurium since the dump output will be used as an actual zone file
4e10d188042815c5285edf00ea96896b862e0863aurium loaded by <span><strong class="command">named</strong></span>.
83aaf46c9feab529aeb9add871c05c3d1177afccaurium When manually specified otherwise, the check levels must at
83aaf46c9feab529aeb9add871c05c3d1177afccaurium least be as strict as those specified in the
83aaf46c9feab529aeb9add871c05c3d1177afccaurium <span><strong class="command">named</strong></span> configuration file.

<dd><p>
Write zone output to <code class="filename">filename</code>.
If <code class="filename">filename</code> is <code class="filename">-</code> then
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.
</p></dd>
<dt><span class="term">-S <em class="replaceable"><code>mode</code></em></span></dt>
<dd><p>
Check if a SRV 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>
<dt><span class="term">-t <em class="replaceable"><code>directory</code></em></span></dt>
<dd><p>
Chroot to <code class="filename">directory</code> so that
include
directives in the configuration file are processed as if
run by a similarly chrooted named.
</p></dd>
<dt><span class="term">-w <em class="replaceable"><code>directory</code></em></span></dt>
<dd><p>
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
<code class="filename">named.conf</code>.
</p></dd>
<dt><span class="term">-D</span></dt>
<dd><p>
Dump zone file in canonical format.
This is always enabled for <span><strong class="command">named-compilezone</strong></span>.
</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>.
</p></dd>
<dt><span class="term">zonename</span></dt>
<dd><p>
The domain name of the zone being checked.
</p></dd>
<dt><span class="term">filename</span></dt>
<dd><p>
The name of the zone file.
</p></dd>
