It uses the BIND commands for manipulating DNSSEC key + metadata: <span class="command"><strong>dnssec-keygen</strong></span> and + <span class="command"><strong>dnssec-settime</strong></span>. + </p> + <p> + DNSSEC policy can be read from a configuration file (default + <code class="filename">/etc/dnssec-policy.conf</code>), from which the key + parameters, publication and rollover schedule, and desired + coverage duration for any given zone can be determined. This + file may be used to define individual DNSSEC policies on a + per-zone basis, or to set a default policy used for all zones. + </p> + <p> + When <span class="command"><strong>dnssec-keymgr</strong></span> runs, it examines the DNSSEC + keys for one or more zones, comparing their timing metadata against + the policies for those zones. If key settings do not conform to the + DNSSEC policy (for example, because the policy has been changed), + they are automatically corrected. + </p> + <p> + A zone policy can specify a duration for which we want to + ensure the key correctness (<code class="option">coverage</code>). It can + also specify a rollover period (<code class="option">roll-period</code>). + If policy indicates that a key should roll over before the + coverage period ends, then a successor key will automatically be + created and added to the end of the key series. + </p> + <p> + If zones are specified on the command line, + <span class="command"><strong>dnssec-keymgr</strong></span> will examine only those zones. + If a specified zone does not already have keys in place, then + keys will be generated for it according to policy. + </p> + <p> + If zones are <span class="emphasis"><em>not</em></span> specified on the command + line, then <span class="command"><strong>dnssec-keymgr</strong></span> will search the + key directory (either the current working directory or the directory + set by the <code class="option">-K</code> option), and check the keys for + all the zones represented in the directory. + </p> + <p> + It is expected that this tool will be run automatically and + unattended (for example, by <span class="command"><strong>cron</strong></span>). + </p> + </div> + + <div class="refsection"> +<a name="id-1.8"></a><h2>OPTIONS</h2> + <div class="variablelist"><dl class="variablelist"> +<dt><span class="term">-c <em class="replaceable"><code>file</code></em></span></dt> +<dd> + <p> + If <code class="option">-c</code> is specified, then the DNSSEC + policy is read from <code class="option">file</code>.
