Here's a blog entry with more specifics on how do do the things I
suggested:

Thanks Jonesy for the sshguard suggestion. Looks quite a bit simpler
than fail2ban.

By the way, anyone that has ssh access open to the world MUST take
extra precautions. At an absolute minimum, any account that can log in
via ssh MUST have a VERY GOOD PASSWORD - twenty or thirty random
characters including numbers, punctuation and both cases. Otherwise you
WILL get hacked. But it would be a much better idea to read the above
blog entry and implement the first few ideas at least.

Regards, K.
