In addition to what others have suggested, you could use PAM to enforce
account lockouts in the event that the attacker does focus the attempts
on a real account.  The Linux module for this is pam_tally.  You can
also put an unlock script on a cron job to then prevent DoS of all of
your accounts.  Not perfect, but effective.
