By Defect (defect@thearmy.com). Although modkilling is a very simple task, I have taken the time to make this small text on how to do it. I realize that modkilling isn't considered an art, I just needed a good name. Instead of displaying how to modkill in text, I have decided to make one screenshot. As far as I can tell, this should answer all of the questions you have.   Once again, the modkill data (in hex) is 2b2b2b415448300d The reason I set the number of packets to send to 15 is just to make sure that at least one ICMP packet hits the target.
