Speaking of SSH, for those that run Linux on the list and like to leave ssh open - I normally use public/private keys but I don't normally have my laptop or key-on-a-stick with me so I allow passwords as well on my home server.   A little program called "sshdfilter" automatically watches logs (via a named pipe) and when someone comes knocking (or guesses a password wrong x times) it automatically firewalls the IP for a good long time.   I use it on most any host I expose to the Internet with ssh.

Hopefully this isn't too offtopic ...
