<h1> The <tt>s6-ident-client</tt> program </h1>
<p>
<tt>s6-ident-client</tt> is a command-line client application that
performs IDENT (RFC 1413) queries.
</p>
<h2> Interface </h2>
<pre>
s6-ident-client [ -t <em>millisecs</em> ] <em>remoteaddr</em> <em>remoteport</em> <em>localaddr</em> <em>localport</em>
</pre>
<ul>
<li> s6-ident-client contacts the IDENT server on address <em>remoteaddr</em>
port 113 and asks it about the connection from address <em>remoteaddr</em>
port <em>remoteport</em> to address <em>localaddr</em> port <em>localport</em>. </li>
<li> It prints the answer to stdout. </li>
<li> It exits 0 if the answer is positive or 1 if the answer is negative,
in which case it also prints an informative message to stderr. </li>
<li> <em>remoteaddr</em> and <em>localaddr</em> can be either IPv4
or IPv6 addresses; however, they must both be of the same type. </li>
</ul>
<h2> Options </h2>
<ul>
<li> <tt>-t <em>millisecs</em></tt> : if no answer has been
obtained within <em>millisecs</em> milliseconds, s6-ident-client will
exit 99 with an error message. By default, <em>millisecs</em> is 0,
which means no time limit. </li>
</ul>
