<h1> The <tt>dnsfunnel-translate</tt> program </h1>

<p>
<tt>dnsfunnel-translate</tt> translates a file in <tt>resolv.conf</tt>
format to a file in <a href="dnsfunneld.html">dnsfunneld</a> format.
</p>

<h2> Interface </h2>

<pre>
     dnsfunnel-translate [ -i inputfile ] [ -o outputfile ] [ -x ignoredip ]
</pre>

<ul>
 <li> dnsfunnel-translate opens <em>inputfile</em> and parses it. It reads
and processes lines beginning with <tt>nameserver</tt> followed by an IP
address (v4 or v6). It ignores other lines. </li>
 <li> It writes the IP addresses, without the <tt>nameserver</tt> keyword,
to <tt>outputfile</tt>, one per line. </li>
 <li> If a <tt>nameserver</tt> address is <em>ignoredip</em>, it does not
get printed to <tt>outputfile</tt>
 <li> dnsfunnel-translate exits 0 when it has finished processing
<em>inputfile</em>. </li>
</ul>

<h2> Exit codes </h2>

<ul>
 <li> 0: success </li>
 <li> 1: no suitable IP found in the input file </li>
 <li> 100: wrong usage </li>
 <li> 111: system call failed </li>
</ul>

<h2> Options </h2>

<ul>
 <li> <tt>-i&nbsp;<em>inputfile</em></tt>&nbsp;: process <em>inputfile</em>.
Default is <tt>/etc/resolv.conf</tt>. </li>
 <li> <tt>-o&nbsp;<em>outputfile</em></tt>&nbsp;: write the result to
<em>outputfile</em>. Default is <tt>/run/dnsfunnel/root/caches</tt>. </li>
 <li> <tt>-x&nbsp;<em>ignoredip</em></tt>&nbsp;: ignore the <em>ignoredip</em>
IPv4 address if it shows up as a <tt>nameserver</tt> in <em>inputfile</em>.
Default is <tt>127.0.0.1</tt>. The point of this option is to avoid copying
to <tt>outputfile</tt> the IPv4 address that the
<a href="dnsfunneld.html">dnsfunneld</a> daemon will be bound to. </li>
</ul>
