Fail2ban

ban hosts that cause multiple authentication errors

1. clone repository

   git clone https://github.com/fail2ban/fail2ban.git

2. change directory and install the app

   cd fail2ban
   python setup.py install

3. copy config files

   cp config/* /etc/fail2ban/

4. print iptables version

   iptables --version

5. if iptables version >1.4.20 edit the /etc/fail2ban/action.d/iptables-common.conf and set locking opt to empty string:

   lockingopt =

6. create startup script and start the service

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

• NOTE: installation script registers the app to python package system so uninstall is as easy as

  pip uninstall fail2ban
