Resolved Fail2Ban doesn't start after upgrade

I've probably found the cause of things being slow. The number of banned ip-adresses seemes to be high. About 950 entries at this very moment...

I'll just watch how things will evolve.

Once again thanks a lot UFHH01 for your help !
 
Hi Martin6969,

your de-installation process kept some configuration files and executables. Pls. consider to use "yum" to remove the existent fail2ban package:
Code:
yum remove failban plesk-fail2ban-configurator

plesk installer --select-product-id plesk --select-release-current --install-component fail2ban

HI UFHH01,
I have no yum!?:
Code:
yum info fail2ban
-bash: yum: command not found

plesk installer --select-product-id plesk --select-release-current --remove-component fail2ban and
plesk installer --select-product-id plesk --select-release-current --install-component fail2ban not work


There are the errors after upgrade with fail2ban:

or Bildschirmfoto 2017-04-26 um 11.36.50.png


What can I do?
Thanks,
RaHa
 
Hi RaHa,

I have no yum!?
In this case ( Debian/Ubuntu - based systems ), you would use for example:
Code:
aptitude purge failban plesk-fail2ban-configurator

plesk installer --select-product-id plesk --select-release-current --remove-component fail2ban and
plesk installer --select-product-id plesk --select-release-current --install-component fail2ban not work
Could you pls. describe in detail, WHAT doesn't work? Could you pls. post the corresponding "installer.log" ( /var/log/plesk ) ?

Hi UFHH01,
I tried remove-component fail2ban, del /etc/fail2ban and than install-component fail2ban, but there was no new directoy fail2ban. At second call of install-component fail2ban the dir with all content was build, but all jails are deactived. Open an save the jail via Ples will get this error:

I now installed the backup files jail.config and jail.local. file2ban works! (I thought, because there messages in fail2ban.log with new time. Now I see under tools services that file2ban is not running, also after a server restart.)

Hi again,

After a reboot of my server ip2ban stopt working.

Did the 'old' correction again:

Code:
yum remove fail2ban plesk-fail2ban-configurator
plesk installer --select-product-id plesk --select-release-current --install-component fail2ban

Now when i try to start it up i get this error in Onyx :
Code:
Error: Unable to save the settings: f2bmng failed: Created symlink from /etc/systemd/system/multi-user.target.wants/fail2ban.service to /usr/lib/systemd/system/fail2ban.service.
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.

What's happening ?
 
Hi Martin6969,

and WHAT is the output of "systemctl status fail2ban.service" or/and "journalctl -xe", pls. ?

Pls. don't expect us to guess possible error messages - it will not help you, nor does it help people willing to help you. If you see notices like "See "systemctl status XXXXXXX.service" and "journalctl -xe" for details.", you should ALWAYS use these commands in order to investigate your issue/error/problem. ;)

Can't uninstall :
You upgraded over the Plesk Control Panel, I suppose and the automatic kill of the process wasn't yet initiated after the process finished. You either have to wait now 30 minutes, or you could kill the process over the command line, by searching for the process with for example:

Code:
ps -aux | grep installer

... where the output should display a current process with a unique PID - number. Now use this PID - number with your KILL - command:

Code:
kill -9 XXXX
... where XXXX has to be replaced with the unique PID - number you found before. ;)


Afterwards, you are now able to use the new autoinstaller instance, which failed with your previous error message. :)
