Hello List,
with CentOS 7.2 it is not longer possible to run fail2ban on a Server ?
I install a new CentOS 7.2 and the EPEL directory yum install fail2ban
I don't change anything only I create a jail.local to enable the Filters [sshd] enabled = true .... ..... When I start afterward fail2ban systemctl status fail2ban is clean
But systemctl status firewalld is broken

I install a new CentOS 7.2 and the EPEL directory yum install fail2ban
No such issue on a clean test install.
[root@centos7 fail2ban]# rpm -qa fail2ban* fail2ban-sendmail-0.9.3-1.el7.noarch fail2ban-firewalld-0.9.3-1.el7.noarch fail2ban-0.9.3-1.el7.noarch fail2ban-server-0.9.3-1.el7.noarch
Make sure you have fail2ban-firewalld installed as this provides the configuration to use firewallcmd-ipset as default banaction.
Plenty of reasons for the "ERROR: NOT_ENABLED" logging, see man 5 firewalld.dbus.

I have now install three Machines and 12 KVM Clients on my Systems but fail2ban is broken on all systems ???

I am not a Programmer and I search in the Internet, but I found nothing for this Problem.
Can you pleas help a little bit more

?? this are the logs from fail2ban I mean we have a broken ipset and or iptables? I have extra install a "old" CentOS 7 and Test before update, this is working I found the blocked IP's in iptables -L -n ???
Now with 7.2 I have only Errors ??

fail2ban wants to run rpm ??? unless some binaries I have mislabelled this would be suspicious, no??
