    <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 — for example, when submitting

            bug reports — without compromising private data.

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