Rcon client

Hej, jeg tænkte på at nu køre jeg en server med eks ip: 192.168.1.0. På denne køre en counter-strike server. Denne køre på port 27018 eks. Jeg vil gerne kunne lave rcon commandoer fra min hjemmeside således at jeg kan skrive sv_gravity 800 på min hjemmeside og så ændres det til dette på serveren. Jeg kan ikke bruge ssh2 php da dette ikke understøttes af mit webhotel

Jeg har disse koder: rcon.class

<?php
/*
	Basic CS:S Rcon class by Freman.  (V1.00)
    ----------------------------------------------
    Ok, it's a completely working class now with with multi-packet responses

    Contact: printf("%s%s%s%s%s%s%s%s%s%d%s%s%s","rc","on",chr(46),"cl","ass",chr(64),"pri","ya",chr(46),2,"y",chr(46),"net")

    Behaviour I've noticed:
	rcon is not returning the packet id.

example.php:

<?php

include_once("rcon.class.php");

$r = new rcon("194.192.34.241",27013,"rconpass");

echo "Authenticated\n";

//Send a request
var_dump($r->rconCommand("sv_gravity 100"));

Men jeg får denne fejl: Unable to open socket: Connection refused (111)
