  <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.

	    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>.
