I was looking at my /var/log/xferlog files and noticed that a LOT of strange
machines were getting access to my NetBSD machine. I have anonymous
FTP turned off, but otherwise FTP is enabled in /etc/inetd.conf - and
here's what I see:

How are these crackers getting access? I have exactly ONE account on these
machines, with a pretty darn non-obvious password.
This is 1.5T
My other machines are also getting hit, running 1.5.1_BETA
Any thoughts appreciated, because now I'm VERY spooked!
