#Matthew Ife
#Jabber ID and email:deleriux@airattack.co.uk
#Servers name and hostname is different thus server is not dns friendly for other jabber servers. Therefore its easier to get me:

#!/bin/bash
#THIS SCRIPT REQUIRES NETCAT, SOME VERSIONS OF NETCAT ARE CALLED 'nc' SO YOU MIGHT WANT TO CHANGE THE NAME UNDER THE FUNCTION jabber:execute APPROPRIATELY
#My scripts are horribly nastily hacked, but hopefully this one isnt too complex.
