|
|
<p>
|
|
<span><strong class="command">dnssec-signzone</strong></span> signs a zone. It generates
|
|
NSEC and RRSIG records and produces a signed version of the
|
|
zone. The security status of delegations from the signed zone
|
|
(that is, whether the child zones are secure or not) is
|
|
determined by the presence or absence of a
|
|
<code class="filename">keyset</code> file for each child zone.
|
|

</p></dd>

<dd><p>

Generate DS records for child zones from keyset files.
|

Existing DS records will be removed.
|
|
</p></dd>
|
|
<dt><span class="term">-s <em class="replaceable"><code>start-time</code></em></span></dt>
|
|
<dd><p>
|
|
Specify the date and time when the generated RRSIG records
|
|
become valid. This can be either an absolute or relative
|
|
time. An absolute start time is indicated by a number
|
|
in YYYYMMDDHHMMSS notation; 20000530144500 denotes
|
|
14:45:00 UTC on May 30th, 2000. A relative start time is
|
|
indicated by +N, which is N seconds from the current time.
|
|
If no <code class="option">start-time</code> is specified, the current
|
|
time minus 1 hour (to allow for clock skew) is used.
|
|
</p></dd>
|
|
<dt><span class="term">-e <em class="replaceable"><code>end-time</code></em></span></dt>
|
|
<dd><p>
|
|
Specify the date and time when the generated RRSIG records
|
|
expire. As with <code class="option">start-time</code>, an absolute
|
|
time is indicated in YYYYMMDDHHMMSS notation. A time relative
|
|
to the start time is indicated with +N, which is N seconds from
|
|
the start time. A time relative to the current time is
|
|
indicated with now+N. If no <code class="option">end-time</code> is
|
|
specified, 30 days from the start time is used as a default.
|
|
</p></dd>
|
|
<dt><span class="term">-f <em class="replaceable"><code>output-file</code></em></span></dt>
|
|
<dd><p>
|
|
The name of the output file containing the signed zone. The
|
|
default is to append <code class="filename">.signed</code> to the
|
|
input file.
|
|
</p></dd>
|
|
<dt><span class="term">-h</span></dt>
|
|
<dd><p>
|
|
Prints a short summary of the options and arguments to
|
|
<span><strong class="command">dnssec-signzone</strong></span>.
|
|
</p></dd>
|
|
<dt><span class="term">-i <em class="replaceable"><code>interval</code></em></span></dt>
|
|
<dd>
|
|
<p>
|
|
When a previously signed zone is passed as input, records
|
|
may be resigned. The <code class="option">interval</code> option
|
|
specifies the cycle interval as an offset from the current
|
|
time (in seconds). If a RRSIG record expires after the
|
|
cycle interval, it is retained. Otherwise, it is considered
|
|
to be expiring soon, and it will be replaced.
|
|
</p>
|
|
<p>
|
|
The default cycle interval is one quarter of the difference
|
|
between the signature end and start times. So if neither
|
|
<code class="option">end-time</code> or <code class="option">start-time</code>
|
|
are specified, <span><strong class="command">dnssec-signzone</strong></span> generates
|
|
signatures that are valid for 30 days, with a cycle
|
|
interval of 7.5 days. Therefore, if any existing RRSIG records
|
|
are due to expire in less than 7.5 days, they would be
|
|
replaced.

|
</p>
|
|
</dd>
|
|
<dt><span class="term">-n <em class="replaceable"><code>ncpus</code></em></span></dt>
|
|
<dd><p>
|
|
Specifies the number of threads to use. By default, one
|
|
thread is started for each detected CPU.
|
|
</p></dd>
|
|
<dt><span class="term">-o <em class="replaceable"><code>origin</code></em></span></dt>
|
|
<dd><p>
|
|
The zone origin. If not specified, the name of the zone file
|
|
is assumed to be the origin.
|
|
</p></dd>
|
|
<dt><span class="term">-p</span></dt>
|
|
<dd><p>
|
|
Use pseudo-random data when signing the zone. This is faster,
|
|
but less secure, than using real random data. This option
|
|
may be useful when signing large zones or when the entropy
|
|
source is limited.
|
|
</p></dd>
|
|
<dt><span class="term">-r <em class="replaceable"><code>randomdev</code></em></span></dt>
|
|
<dd><p>
|
|
Specifies the source of randomness. If the operating
|
|
system does not provide a <code class="filename">/dev/random</code>
|
|
or equivalent device, the default source of randomness
|
|
is keyboard input. <code class="filename">randomdev</code> specifies
|
|
the name of a character device or file containing random
|
|
data to be used instead of the default. The special value
|
|
<code class="filename">keyboard</code> indicates that keyboard
|
|
input should be used.

The keys used to sign the zone. If no keys are specified, the

<a name="id2550068"></a><h2>EXAMPLE</h2>
|
|
<p>
|
|
The following command signs the <strong class="userinput"><code>example.com</code></strong>
|
|
zone with the DSA key generated in the <span><strong class="command">dnssec-keygen</strong></span>
|
|
man page. The zone's keys must be in the zone. If there are
|
|
<code class="filename">keyset</code> files associated with child zones,
|
|
they must be in the current directory.
|
|
<strong class="userinput"><code>example.com</code></strong>, the following command would be
|
|
issued:
|
|
</p>
|
|
<p>
|
|
<strong class="userinput"><code>dnssec-signzone -o example.com db.example.com Kexample.com.+003+26160</code></strong>
|
|
</p>
|
|
<p>
|
|
The command would print a string of the form:
|
|
</p>
|
|
<p>
|
|
In this example, <span><strong class="command">dnssec-signzone</strong></span> creates
|
|
the file <code class="filename">db.example.com.signed</code>. This file
|
|
should be referenced in a zone statement in a
|
|
<code class="filename">named.conf</code> file.
