changelog

sshdfilter automatically blocks ssh brute force attacks by reading sshd log output in real time and adding iptables rules based on authentication failures.

Block rules are created by logging on with an invalid user name, or wrongly guessing the password for an existing account.

Block rules are removed after a week to maintain a small list of blocks. It also comes with a LogWatch filter.
