</div>
<div class="refsection">
<a name="id-1.7"></a><h2>DESCRIPTION</h2>
<p><span class="command"><strong>named-checkconf</strong></span>
checks the syntax, but not the semantics, of a
<span class="command"><strong>named</strong></span> configuration file. The file is parsed
and checked for syntax errors, along with all files included by it.
If no file is specified, <code class="filename">/etc/named.conf</code> is read
by default.
</p>
<p>
Note: files that <span class="command"><strong>named</strong></span> reads in separate
parser contexts, such as <code class="filename">rndc.key</code> and
<code class="filename">bind.keys</code>, are not automatically read
by <span class="command"><strong>named-checkconf</strong></span>. Configuration
errors in these files may cause <span class="command"><strong>named</strong></span> to
fail to run, even if <span class="command"><strong>named-checkconf</strong></span> was
successful. <span class="command"><strong>named-checkconf</strong></span> can be run
on these files explicitly, however.
</p>

<div class="variablelist"><dl class="variablelist">
<dt><span class="term">-h</span></dt>
<dd>
<p>
Print the usage summary and exit.
</p>
</dd>
<dt><span class="term">-j</span></dt>
<dd>
<p>
When loading a zonefile read the journal if it exists.
</p>
</dd>
<dt><span class="term">-p</span></dt>
<dd>
<p>
Print out the <code class="filename">named.conf</code> and included files
in canonical form if no errors were detected.
See also the <code class="option">-x</code> option.
</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 <span class="command"><strong>named</strong></span>.
</p>
</dd>
<dt><span class="term">-v</span></dt>
<dd>
<p>
Print the version of the <span class="command"><strong>named-checkconf</strong></span>
program and exit.
</p>
</dd>
<dt><span class="term">-x</span></dt>
<dd>
<p>
When printing the configuration files in canonical
form, obscure shared secrets by replacing them with
strings of question marks ('?'). This allows the
contents of <code class="filename">named.conf</code> and related
files to be shared — for example, when submitting
bug reports — without compromising private data.
This option cannot be used without <code class="option">-p</code>.
</p>
</dd>
<dt><span class="term">-z</span></dt>
<dd>
<p>
Perform a test load of all master zones found in
<code class="filename">named.conf</code>.
</p>
</dd>
<dt><span class="term">filename</span></dt>
<dd>
<p>
The name of the configuration file to be checked. If not
specified, it defaults to <code class="filename">/etc/named.conf</code>.
</p>
</dd>
</dl></div>
</div>
<div class="refsection">
<a name="id-1.9"></a><h2>RETURN VALUES</h2>
<p><span class="command"><strong>named-checkconf</strong></span>
returns an exit status of 1 if
errors were detected and 0 otherwise.
