from the doc: 'This is just some dumb lame shit i whiped together (i have no life) :what it basicly does is sends a syn request to the IP that i put in there and the server sends back unreach code cuz the port isnt open,therefore if you send a mass ammount of syn requests from a spoofed ip the IP your spoofing gets all that nasty un-reach sent to them,and since its only a syn request it uses just about 0 bandwith :P (i think) i really dont know what im talking about sometimes so forgive me if im wrong on anything dont change the server port. just put the IP you want bombed under global IP1 and crank up the loop on the packet and blast away i dont know how bad this will lag someone as i havent tested it out because i dont DoS :P'
