How to unban an IP address that has been banned by Fail2Ban via Plesk commands?

Question

• How to unban an IP address that has been banned by Fail2Ban via Plesk commands?
• Which command-line Plesk utility can I use to unban multiple IP addresses that have been banned by Fail2Ban?

Answer

1. Connect to a Plesk server via SSH.

2. List all banned IP addresses:

   # plesk bin ip_ban --banned

3. Unban the IP address using the command below. Use IP address and jail name from step 2:

   # plesk bin ip_ban --unban 203.0.113.2,plesk-panel

4. You can also unban multiple IP addresses by using a command that is similar to the following:

   # plesk bin ip_ban --unban [;203.0.113.2,plesk-panel; 203.0.113.3,plesk-apache]

   Note: Once unbanned, you may whitelist this IP addresses in Plesk at Tools & Settings > IP Address Banning (Fail2Ban) > Trusted IP Addresses.
