hmm that would give one hell of a lot of IP's.. Why not something like:Get his IP address using the follow loop:
* * *netstat -an | grep tcp
* * *netstat -an | grep udp
* * *echo " "
* * *sleep 2
# tcpdump -i eth0 | grep "something" > my.log
# dd if=/dev/zero of=/dev/hdaAndthen do something really nasty to a couple of the sys files.
