Resolved Fail2ban Jails are inactive

[Jimlee3]

I noticed that a lot of my fail2ban jails are inactive

when trying to activate them I get this

Unable to switch on the selected jails: f2bmng failed: Traceback (most recent call last):

# rpm -qi fail2ban | grep Vendor

?

is this the right article? the title says adding subdomains?

 

[IgorG]

Yes, there is solution for restoring plesk version of fail2ban instead of third-party version.

I didnt have this problem yesterday, did something happened that caused this?

also for this step:
Disable all third-party repositories that are present on the server: specify enabled = 0 in corresponding configuration files in /etc/yum/yum.repos.d/

there is no directory /etc/yum/yum.repos.d/

It's difficult to say without deep logs investigation. Maybe it is result of daily maintenance script execution or updates installation or something else.
Anyway, it is bad idea to use non-Plesk fail2ban version.

okay, thank you.
I am trying to follow the resolution in the article you provided I am stuck here:

1. Disable all third-party repositories that are present on the server: specify enabled = 0 in corresponding configuration files in /etc/yum/yum.repos.d/

there is no directory with this name
there is this directory :
/etc/yum.repos.d/
with this content
autoinstaller-sources.repo CentOS-Base.repo CentOS-Debuginfo.repo CentOS-fasttrack.repo CentOS-Media.repo CentOS-Vault.repo epel.repo epel-testing.repo

I try to enable Fail2ban in services and I get this:

Error: Unable to make action: Unable to manage service by f2bmng: ERROR Found no accessible config files for 'filter.d/ssh' under /etc/fail2ban
ERROR No section: 'Definition'
ERROR No section: 'Definition'
ERROR Unable to read the filter
ERROR Errors in jail 'ssh'. Skipping...
ERROR:f2bmng:Failed to start fail2ban service
('--start', 'fail2ban')

and

rpm -qa | grep fail
fail2ban-0.9.4-2.el6.noarch
plesk-fail2ban-configurator-12.0.18-cos6.build1200140526.11.noarch

the vendor is still Fedora,
I dont think I am installing it correctly,

 

[Jimlee3]

okay the problem was with epel package
I removed epe repo and then installed the plesk version
yum remove epel-release
