DenyHosts is a nice option. You may also wanna have something for brute force detection. BFD is a nice option for it:

fail2ban scans thro your log files and detects strange login behaviour : http://www.fail2ban.org/wiki/index.php/Main_Page
I use it to add DENY rules to iptables ( for 7 days )for IP's who try to log 3x into my server with failed attempts.
After 7 days fail2ban remove that firewall rule so the ip can try again. ( ofcourse it's up to you for how many days you choose to ban it )
It can also send you daily reports via email.
