Issue Error activating Fail2Ban

[jorgemartincasasola]

Goodnight:

I am trying to activate Fail2Ban from the Plesk Panel, but I always get this error message:

Error: Failed to save settings:f2bmng failed: Job for fail2ban.service failed because the control process exited with error code. See "systemctl status fail2ban.service" and "journalctl -xe" for details.
ERROR:f2bmng:Failed to start fail2ban service

Command #service fail2ban status

Where the problem lies?

A greeting and thanks in advance.

Hi jorgemartincasasola,

pls. see as well depending log - entries from "/var/log/fail2ban.log" and don't forget the second suggestion from your error - message for investigations reasons:

See "systemctl status fail2ban.service" and "journalctl -xe" for details.

In addition, it would really help if you would provide informations about:

• Your operating system
• Your current Plesk version ( incl. MU )

A common reason why Fail2Ban can't start is the absent directory "/var/run/fail2ban". Pls. make sure that the directory exists and that it has the correct permissions ( 0755 / user: root / group: root ).

COMMAND TO USE OVER THE COMMAND LINE - logged in as user "root":

mkdir -p /var/run/fail2ban

Another common reason might be the missing file "/var/log/fail2ban.log". Pls. consider to create it manually with for example:

COMMAND TO USE OVER THE COMMAND LINE - logged in as user "root":

touch /var/log/fail2ban.log
