Identify Portscanners


There are some tools to check who is portscanning your machine and when. A good tool seems to be ippl, the IP Protocols Logger, but others include snort and portsentry.

In kernel 2.4 iptables has a mechanism for portscans where you can set it up so that most portscans will take hours to return nothing.
