<title>Locking</title>
<para>Some applications (e.g. <application>mutt</application>)
require file locking to operate correctly. In the case of
<acronym>NFS</acronym>, <application>rpc.lockd</application>
can be used for file locking. To enable it, add the following
to the <filename>/etc/rc.conf</filename> file on both client
and server (it is assumed that the <acronym>NFS</acronym>
client and server are configured already):</para>
<programlisting>rpc_lockd_enable="YES"
rpc_statd_enable="YES"</programlisting>
<para>Start the application by using:</para>
<screen>&prompt.root; <userinput>/etc/rc.d/nfslocking start</userinput></screen>
<para>If real locking between the <acronym>NFS</acronym> clients
and <acronym>NFS</acronym> server is not required, it is
possible to let the <acronym>NFS</acronym>client do locking
locally by passing <option>-L</option> to &man.mount.nfs.8;.
Refer to the &man.mount.nfs.8; manual page for further details.
