How do you discover the size of a UDP packet? I used ethereal and router logs and saw I was being DDoSed from all different ports, when DDoS's are done are they all the same packet size, and can be filtered. Adding all the drones IP's in iptables is tedious work...Oh yea he lives in the UK, where I dont think botnets are illegal. I toke screen shots of all his Xdcc bots what can i do to report him..not something to get his domain canceled but to legally take action.
