What was the motivation behind DenyHosts?
I run a number of Linux servers and I noticed that one of them was hacked into. Upon browsing my sshd log I noticed that the system was targeted for some time and eventually, somebody hacked out a password. Had I been using DenyHosts, that never would’ve happened (if only I had the foresight to write this script before my system was compromised!). I then looked at the logs of my other servers, and noticed hundreds of break-in attempts. I wanted to thwart these hosts and future attackers from attempting to hack into my system.
