How to manage Fail2Ban and its jails in Plesk for Linux

Fail2Ban is a foolproof intrusion prevention software that helps protect your servers from brute-force attacks. Furthermore, it scans log files and bans IPs with malicious signs in order to protect your servers. Its ability to perform multiple actions while detecting an abusive IP address makes it a popular software today.

A Fail2Ban jail combines a filter along with one or more actions. Moreover, Fail2ban relies on jails to block malicious hosts from causing trouble.

Our Support Techs have come up with two innovative ways to help you manage Fail2Ban and its jails via Plesk.

    # plesk bin ip_ban –enable
    # plesk bin ip_ban –disable
  3. Next, we can take a look at the list of available jails with this command:
    # plesk bin ip_ban –jails
  4. After that, we have to enable or disable a jail with the following commands:
