iptstate – Who you talkin’ to Willis?!?!

I was playing around with iptables today on some new boxen and found an old tool I had forgotten about.  iptstate is like top for iptables.  It’s a cool tool used to see who is connecting to your linux pc.  Here’s an example of the output (with the ip addresses and ports changed to protect the innocent!):
