  • 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.


python ≥ 2.3
gamin ≥ 0.0.21

To install, just do:

tar xvfj fail2ban-0.8.4.tar.bz2
cd fail2ban-0.8.4
python install

This will install [file:///usr/share/fail2ban Fail2Ban]. The executable scripts are placed into file:///usr/bin.

  • It is possible that Fail2Ban is already packaged for your distribution. In this case, you should use it.

Fail2Ban should be correctly installed now. Just type:

fail2ban-client -h

to see if everything is all right.  You should always use fail2ban-client and never call fail2ban-server directly.


You can configure Fail2Ban using the [file:///etc/fail2ban configuration files].  It is possible to configure the server using commands sent to it by fail2ban-client.  The available commands are described in the [man:/fail2ban-client manual page].  Please refer to it or to the website.
