A reasonable security system would shut down the login process for a

And how does one go about turning that option on, with say a 15 minute timeout?
Check out pam_abl on http://www.hexten.net/pam_abl/ (SourceForge
project).
If you want to go this route, both denyhosts and pam_abl are available
for Fedora Extras.
I've also use a Perl script to add these IP addresses to an iptables
list but even with summarization I had thousands of denies. So I
only allow a select few sites to get to my ssh and the attacks have
completely stopped. Though I will say I'm not doing this commercially.
