It logs what it's doing on stderr. The environment +variables <em>x</em>LOCALIP and <em>x</em>REMOTEIP, where <em>x</em> is +the value of the PROTO environment variable, must contain the IDENT +server address and the IDENT client address, respectively. +</p> + +<p> + minidentd exits 0 on success, 100 on a usage error and 111 on a system +call failure. +</p> + +<p> + minidentd does not contact the network directly. It's meant to +run under a superserver like +<a href="s6-tcpserver.html">s6-tcpserver</a>. minidentd will +work with IPv4 as well as IPv6. +</p> + +<h2> Options </h2> + +<ul> + <li> <tt>-v</tt> : verbose mode. Log queries and replies.. </li> + <li> <tt>-n</tt> : send ERROR : HIDDEN-USER replies if +the user has a <tt>.ident</tt> file in his home directory. </li> + <li> <tt>-i</tt> : user-defined answers. The first 14 chars of the +user's <tt>.ident</tt> file, up to EOF or newline, are used instead of +the user name. If the file exists and is empty, send +ERROR : HIDDEN-USER. If it doesn't exist, send a normal reply. </li> + <li> <tt>-r</tt> : send random replies. </li> + <li> <tt>-y <em>file</em></tt> : valid with <tt>-n</tt> or <tt>-i</tt>. +Use <em>file</em> instead of <tt>.ident</tt>. </li> + <li> <tt>-t <em>timeout</em></tt> : close connection after +<em>timeout</em> milliseconds without a client request. </li> +</ul> + +<h2> Notes </h2> + +<ul> + <li> minidentd works only under Linux (2.2 or later); +on other systems, it will compile and run, but report an error for every +request. +The problem is that <em>there is no portable Unix way</em> of listing active +outgoing TCP connections with the relevant uids. On Linux, minidentd parses +the <tt>/proc/net/tcp</tt> or <tt>/proc/net/tcp6</tt> virtual file. Other +systems have their own way of doing this, if you want your system to be +supported by minidentd, please contact the author. </li> +</ul> + +</body> +</html> |
