Utility to help sys admins thwart SSH crackers


DenyHosts is a program that automatically blocks SSH brute-force attacks by adding entries to /etc/hosts.deny. It will also inform Linux administrators about offending hosts, attacked users and suspicious logins.

Synchronization with a central server is possible too.

Differently from other software that do same work, denyhosts doesn't need support for packet filtering or any other kind of firewall in your kernel.

DenyHosts unfortunately does not support IPv6.
