I use denyhosts -- it's a script that looks at your log file and after X
failed attempts to login via ssh it blocks the IP in your firewall for a
specified period. Also nice if you don't really trust all the passwords
for ssh to withstand a rigorous dictionary attack (but doesn't stop a
distributed dictionary attack).
