Fail2Ban: ban hosts that cause multiple authentication errors

Fail2Ban scans log files like /var/log/auth.log and bans IP addresses having too many failed login attempts. It does this by updating system firewall rules to reject new connections from those IP addresses, for a configurable amount of time. Fail2Ban comes out-of-the-box ready to read many standard log files, such as those for sshd and Apache, and is easy to configure to read any log file you choose, for any error you choose.

Though Fail2Ban is able to reduce the rate of incorrect authentications attempts, it cannot eliminate the risk that weak authentication presents. Configure services to use only two factor or public/private authentication mechanisms if you really want to protect services.

This README is a quick introduction to Fail2ban. More documentation, FAQ, HOWTOs are available in fail2ban(1) manpage and on the website http://www.fail2ban.org

Installation:

It is possible that Fail2ban is already packaged for your distribution. In this case, you should use it instead.

Required:

Optional:

To install, just do:

tar xvfj fail2ban-0.9.6.tar.bz2
cd fail2ban-0.9.6
python setup.py install

This will install Fail2Ban into the python library directory. The executable scripts are placed into /usr/bin, and configuration under /etc/fail2ban.

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.

Please note that the system init/service script is not automatically installed. To enable fail2ban as an automatic service, simply copy the script for your distro from the files directory to /etc/init.d. Example (on a Debian-based system):

cp files/debian-initd /etc/init.d/fail2ban
update-rc.d fail2ban defaults
service fail2ban start

Configuration:

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 fail2ban-client(1) manpage. Also see fail2ban(1) and jail.conf(5) manpages for further references.

You just appreciate this program:

send kudos to the original author ([Cyril Jaquier](mailto: Cyril Jaquier cyril.jaquier@fail2ban.org)) or better to the mailing list since Fail2Ban is "community-driven" for years now.
