It challenges the server by it\'s IP using the RCON protocol, using that it sends it along with the rcon password and the command to execute when you try to send a command. It was made to almost mimic the real console (text-based) in half-life, which is why I didn\'t make a dialog for it. You can change game settings with it and also view the live logs of what is happening in the server (e.g. player 1 killed player2 with gun).
