Right, so if I can only SSH into my box by having the appropriate RSA keys configured, is there any point in using Denyhosts for SSH as well? Or is Denyhosts only looking at keyboard-interactive / password logins for SSH?
Don't get me wrong, Denyhosts is the absolute mac-daddy, but I've recently switched off keyboard-interactive logins altogether and wondered if it was worth still keeping Denyhosts running.
(If you don't know Denyhosts, it basically maintains - and uses - an IP blacklist of people who keep trying to get into SSH but with the wrong username / password etc.)
