  • Fail2Ban (version 0.8.4) 2009/09/07

Fail2Ban scans log files like [file:///var/log/pwdfail pwdfail] and bans IP addresses that make too many password failures.  It updates firewall rules to reject the IP address.  These rules can be defined by the user.  Fail2Ban can read multiple log files such as sshd or Apache Web server ones. This README is a quick introduction to Fail2Ban.  More documentation, FAQ, HOWTOs are available on the project website.
