<refsection><info><title>DESCRIPTION</title></info>

<para><command>named-checkconf</command>

checks the syntax, but not the semantics, of a

<command>named</command> configuration file. The file is parsed

and checked for syntax errors, along with all files included by it.

If no file is specified, <filename>/etc/named.conf</filename> is read

by default.

</para>

<para>

Note: files that <command>named</command> reads in separate

parser contexts, such as <filename>rndc.key</filename> and

<filename>bind.keys</filename>, are not automatically read

by <command>named-checkconf</command>. Configuration

errors in these files may cause <command>named</command> to

fail to run, even if <command>named-checkconf</command> was

successful. <command>named-checkconf</command> can be run

on these files explicitly, however.

<listitem>

<para>

Chroot to <filename>directory</filename> so that include

directives in the configuration file are processed as if

run by a similarly chrooted <command>named</command>.

</para>

</listitem>

</varlistentry>

<varlistentry>

<listitem>

<para>

Print the version of the <command>named-checkconf</command>

program and exit.

<term>-p</term>

<listitem>

<para>

Print out the <filename>named.conf</filename> and included files

in canonical form if no errors were detected.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-x</term>

<listitem>

<para>

When printing the configuration files in canonical

form, obscure shared secrets by replacing them with

strings of question marks ('?'). This allows the

contents of <filename>named.conf</filename> and related

files to be shared &mdash; for example, when submitting

bug reports &mdash; without compromising private data.

This option cannot be used without <option>-p</option>.
