I came back from dinner to hear the server on my desk clicking loudly and consistantly. It was a regular hard drive read/write sound, but the server is an old enough machine that the constant "tik tik" every other second quickly became annoying.
It was yet another brute-force SSH dictionary attack. I haven't seen many live attacks in my life that weren't during a hacking contest, so I was a little creeped out watching my auth.log grow as some script somewhere was badgering my little Dell. (The more experienced can feel free to mutter, "You ain't seen nuthin, kid.")
Needless to say, here's the latest addition I added to our apartment's firewall config:
block in quick on $ext_if inet from $bastards to any
