I play DeltaForce 2 online and people send messages about how they will hack your computer. I've had my computer freeze up several times while playing. Not sure if it was a coincidence or not. Are there ip sniffing programs that will let you know other players IP addresses even though you are not connected to there computer. I know that if I connect to a private server that the sysadmin will know my ip, but how about those other players?
