I‘ve followed your guide and installed denyhosts to protect on my RedHat 5.3 OpenSSH based server. However, I’ve been accidentally blocked out from my home ADSL IP address. I tried removing my blocked IP from /etc/hosts.deny, but it did blocked it again quickly. It appears that DenyHosts keeps track of the attempts somewhere on disk or memory. How do I remove my own home IP address from DenyHosts?
