|
||
|
||
<p>
|
||
<span class="command"><strong>tsig-keygen</strong></span> and <span class="command"><strong>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 class="command"><strong>rndc</strong></span> command channel.
|
||
</p>
|
||
|
||
<p>
|
||
When run as <span class="command"><strong>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 class="command"><strong>ddns-confgen</strong></span>, the generated
|
||
key is accompanied by configuration text and instructions
|
||
that can be used with <span class="command"><strong>nsupdate</strong></span> and
|
||
<span class="command"><strong>named</strong></span> when setting up dynamic DNS,
|
||
including an example <span class="command"><strong>update-policy</strong></span>
|
||
statement. (This usage similar to the
|
||
<span class="command"><strong>rndc-confgen</strong></span> command for setting
|
||
up command channel security.)
|
||
</p>
|
||
|
||
<p>
|
||
Note that <span class="command"><strong>named</strong></span> itself can configure a
|
||
local DDNS key for use with <span class="command"><strong>nsupdate -l</strong></span>:
|
||
it does this when a zone is configured with
|
||
<span class="command"><strong>update-policy local;</strong></span>.
|
||
<span class="command"><strong>ddns-confgen</strong></span> is only needed when a
|
||
more elaborate configuration is required: for instance,
|
||
if <span class="command"><strong>nsupdate</strong></span> is to be used from a remote
|
||
system.

|
||
|
||
|
||
<div class="variablelist"><dl class="variablelist">
|
||
<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 class="command"><strong>ddns-confgen</strong></span> only.) Quiet mode: Print
|
||
only the key, with no explanatory text or usage examples;
|
||
This is essentially identical to <span class="command"><strong>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.

<dd>
|
||
<p>
|
||
(<span class="command"><strong>ddns-confgen</strong></span> only.)
|
||
Generate configuration example to allow dynamic updates
|
||
of a single hostname. The example <span class="command"><strong>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>

(<span class="command"><strong>ddns-confgen</strong></span> only.)
|
||
Generate configuration example to allow dynamic updates
|
||
of a zone: The example <span class="command"><strong>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.
