<a name="id2661880"></a><h2>DESCRIPTION</h2>
<p>
<span><strong class="command">tsig-keygen</strong></span> and <span><strong class="command">ddns-confgen</strong></span>
are invocation methods for a utility that generates keys for use
in TSIG signing. The resulting keys can be used, for example,
to secure dynamic DNS updates to a zone or for the
<span><strong class="command">rndc</strong></span> command channel.
</p>
<p>
When run as <span><strong class="command">tsig-keygen</strong></span>, a domain name
can be specified on the command line which will be used as
the name of the generated key. If no name is specified,
the default is <code class="constant">tsig-key</code>.
</p>
<p>
When run as <span><strong class="command">ddns-confgen</strong></span>, the generated
key is accompanied by configuration text and instructions
that can be used with <span><strong class="command">nsupdate</strong></span> and
<span><strong class="command">named</strong></span> when setting up dynamic DNS,
including an example <span><strong class="command">update-policy</strong></span>
statement. (This usage similar to the
<span><strong class="command">rndc-confgen</strong></span> command for setting
up command channel security.)
</p>
<p>
Note that <span><strong class="command">named</strong></span> itself can configure a
local DDNS key for use with <span><strong class="command">nsupdate -l</strong></span>:
it does this when a zone is configured with
<span><strong class="command">update-policy local;</strong></span>.
<span><strong class="command">ddns-confgen</strong></span> is only needed when a
more elaborate configuration is required: for instance,
if <span><strong class="command">nsupdate</strong></span> is to be used from a remote
system.

<a name="id2662188"></a><h2>OPTIONS</h2>
<div class="variablelist"><dl>
<dt><span class="term">-a <em class="replaceable"><code>algorithm</code></em></span></dt>
<dd><p>
Specifies the algorithm to use for the TSIG key. Available
choices are: hmac-md5, hmac-sha1, hmac-sha224, hmac-sha256,
hmac-sha384 and hmac-sha512. The default is hmac-sha256.
Options are case-insensitive, and the "hmac-" prefix
may be omitted.
</p></dd>
<dt><span class="term">-h</span></dt>
<dd><p>
Prints a short summary of options and arguments.
</p></dd>
<dt><span class="term">-k <em class="replaceable"><code>keyname</code></em></span></dt>
<dd><p>
Specifies the key name of the DDNS authentication key.
The default is <code class="constant">ddns-key</code> when neither
the <code class="option">-s</code> nor <code class="option">-z</code> option is
specified; otherwise, the default
is <code class="constant">ddns-key</code> as a separate label
followed by the argument of the option, e.g.,
<code class="constant">ddns-key.example.com.</code>
The key name must have the format of a valid domain name,
consisting of letters, digits, hyphens and periods.
</p></dd>
<dt><span class="term">-q</span></dt>
<dd><p>
(<span><strong class="command">ddns-confgen</strong></span> only.) Quiet mode: Print
only the key, with no explanatory text or usage examples;
This is essentially identical to <span><strong class="command">tsig-keygen</strong></span>.
</p></dd>
<dt><span class="term">-r <em class="replaceable"><code>randomfile</code></em></span></dt>
<dd><p>
Specifies a source of random data for generating the
authorization. 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.
</p></dd>
<dt><span class="term">-s <em class="replaceable"><code>name</code></em></span></dt>
<dd><p>
(<span><strong class="command">ddns-confgen</strong></span> only.)
Generate configuration example to allow dynamic updates
of a single hostname. The example <span><strong class="command">named.conf</strong></span>
text shows how to set an update policy for the specified
<em class="replaceable"><code>name</code></em>
using the "name" nametype. The default key name is
ddns-key.<em class="replaceable"><code>name</code></em>.
Note that the "self" nametype cannot be used, since
the name to be updated may differ from the key name.
This option cannot be used with the <code class="option">-z</code> option.
</p></dd>
<dt><span class="term">-z <em class="replaceable"><code>zone</code></em></span></dt>
<dd><p>
(<span><strong class="command">ddns-confgen</strong></span> only.)
Generate configuration example to allow dynamic updates
of a zone: The example <span><strong class="command">named.conf</strong></span> text
shows how to set an update policy for the specified
<em class="replaceable"><code>zone</code></em>
using the "zonesub" nametype, allowing updates to
all subdomain names within that
<em class="replaceable"><code>zone</code></em>.
This option cannot be used with the <code class="option">-s</code> option.
