Brute-Force SSH Server Attacks Surge -- InformationWeek

[Cole Tuininga]

Just another tool that does something similar to sshguard - denyhosts.
(http://denyhosts.sf.net/)  It's pretty configurable and can actually be
used to monitor other services as well if you're willing to do a little
bit of regex work.  

I have to admit that since I've moved sshd away from port 22, I've not
felt the need to run it anymore.
