       $ sudo cp /etc/fail2ban/jail.conf /etc/fail2ban/jail.local
       

Edit /etc/fail2ban/jail.local, example configuration;

       [ssh-iptables]

       enabled  = enable
       filter   = sshd
       action   = iptables[name=SSH, port=ssh, protocol=tcp]
                  sendmail-whois[name=SSH, dest=admin@box, sender=fail2ban@box, sendername="fail2ban"]
                  logpath  = /var/log/auth
                  maxretry = 5
