		<p>Net_Ident - PHP Ident Client Class</p>

		<h1><a name="SYNOPSIS">SYNOPSIS</a></h1>

	require_once 'Net/Ident.php';
	$ident   = new Net_Ident;
	$user    = $ident-&gt;getUser();
	$os_type = $ident-&gt;getOsType();
	echo "user: $user, operating system: $os_type\n";


		<h1><a name="OVERVIEW">OVERVIEW</a></h1>
		<p><tt>Net_Ident</tt> is an RFC 1413 compatible PHP4 Ident client
		class. The Identification Protocol (a.k.a., "ident", a.k.a., "the Ident
		Protocol") provides a means to determine the identity of a user of a
		particular TCP connection.  Given a TCP port number pair, it returns a
		character string which identifies the owner of that connection on the
		server's system.</p>

		<h1><a name="CONSTRUCTOR">CONSTRUCTOR</a></h1>
		<blockquote><tt>$ident = Net_Ident($remote_addr, $remote_port,
				$local_port, $ident_port, $timeout)</tt></blockquote>
		<p>The constructor of this class accepts five optional arguments.
		<tt>$remote_addr</tt> is the IP address or DNS hostname of the remote
		computer running the ident server. <tt>$remote_port</tt> is the port
		number the remote computer is using to make a connection to the local
		machine. PHP can access the remote port for a given HTTP connection
		using the <tt>REMOTE_PORT</tt> environment variable.
		<tt>$local_port</tt> is the local port being connected to. Regular HTTP
		connections will be on port 80, HTTPS connections on port 443. A more
		robust solution would be to use the <tt>SERVER_PORT</tt> environment
		variable to specify this port. You can specify also
		<tt>$ident_port</tt> parameter, port where ident server of client
		machine is listening and also socket timeout using <tt>$timeout</tt>

		<p>There is no need to pass these variables into constructor. They will
		be initialized by default, if not present. See example above.</p>

		<p>TCP connection to the remote ident server will be established oly if
		it will be really needed. After this, also ident query will be made.
		The result of this query can be fetched using methods
		<tt>getUser()</tt> and <tt>getOsType()</tt>.</p>

		<h1><a name="METHODS">METHODS</a></h1>
		<p>Performs ident network query. This is done automatically when
		object is requested for returning particular user or operating system
		data. You can force query performing with this method, so it is
		possible to make more requests with only one Net_Ident object. Returns
		PEAR_Error on connection error or rawdata read from socket on

		<p>Returns a string containing the last error message returned by the
		remote ident server.</p>

		<p>Returns a string containing the <tt>USERID</tt> returned by the
		remote ident server. This will return false if there was an error with
		the query.</p>

		<p>Returns a string containing the operating system type of the remote
		host, as returned by the remote ident server. Permitted values may be
		an ASCII string or a numerical code compliant with RFC 1340, "Assigned
