Plesk12 + Centos 7 + fail2ban 0.9-9.el7 = error

RedEnzian

New Pleskian
Hello,

we are currently setting up our new dedicated server. As stated in the title we use Plesk12, Centos 7 and fail2ban 0.9-9.el7.

we can switch on every single jail, but when we add one more or trying to enable 2 or more at the same time we get an error like this in plesk:

Code:
Unable to switch on the selected jails: f2bmng failed: WARNING 'actioncheck' not defined in 'Definition'. Using default one: ''
ERROR NOK: ('proftpd',)
ERROR NOK: ('sshd',)
ERROR NOK: ('Cannot change database when there are jails present',)
ERROR:f2bmng:Command '['/usr/bin/fail2ban-client', 'reload', 'sshd']' returned non-zero exit status 255
ERROR:f2bmng:Failed to reload following jails due to errors in configuration: sshd

[[errorJailNotDisabled]]

and this in the logfile:

already used bootstrap repair, reinstalled fail2ban and fail2ban configurator

can somebody help?

with best regards

€dit:

one last thing which bothered me ... i have seen tutorials where they activate jails before enabling intrusion detection ... i didn´t have the "switch on" button in the interface as long as fail2ban is not active.

Plesk 12.0 ships with own fail2ban component. Fail2ban 0.9 is not supported due its beta status.
