I was playing in a CS server and was accused of cheating. The admin stated he was going to "Connect my IP to my computer, so I'll know if he turns a hack on." I promptly turned on Ethereal, after a few minutes, I started getting alot of weird packets. I would get a UDP packet from a randomly IP, then it would try to make my computer send an ICMP packet back, but it says destination unreachable. I immediately did an nslookup to see where this guy was located roughly, since most ISPs put the state name (Like Texas) into the host name. According to the DNS server, there is no such IP.
I make idle packet captures on a random basis, just to see if there is anything going on in my machine that I dont know about. Typically its all the same. But I've been getting the same UDP packet from multiple IPs, some exist, some dont (Discovered via nslookup) and it tries to force a reply in ICMP to their machine. I have a registry edit so my computer does not redirect ICMPs.
Any ideas?
