What I've done: 1. Change ssh port to a random non privileged, non
used port.  2. Use good passwords.  3. Install DenyHosts and change
the default "protective" settings to "brutally unforgiving" as in
after 5 tries at a password on any account real or fantastic, that
host is denied all services for forever.

You might want to read a recent SLLUG thread on this.
