Fail2Ban (version 0.8.2)                           2008/03/06

Fail2Ban scans log files like /var/log/pwdfail and bans IP
that makes 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


   >=python-2.3 (

   >=gamin-0.0.21 (

To install, just do:

> tar xvfj fail2ban-0.8.2.tar.bz2
> cd fail2ban-0.8.2
> python install

This will install Fail2Ban into /usr/share/fail2ban. The
executable scripts are placed into /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 alright. You should always use
fail2ban-client and never call fail2ban-server directly.


You can configure Fail2ban using the files in /etc/fail2ban.
It is possible to configure the server using commands sent to
it by fail2ban-client. The available commands are described
in the man page of fail2ban-client. Please refer to it or to
the website:
