Well, I find one thing interesting.....

Notice the error message....

fail2ban-client[2804]: ERROR  Directory /var/run/fail2ban exists but not accessible for writing

But, if you execute the command in the service file from the command line....

[root at f18x log]# /usr/bin/fail2ban-client -x start
2013-07-09 18:46:10,558 fail2ban.server : INFO   Starting Fail2ban v0.8.10
2013-07-09 18:46:10,559 fail2ban.server : INFO   Starting in daemon mode

and....

[root at f18x fail2ban]# pwd
/var/run/fail2ban
[root at f18x fail2ban]# ls
fail2ban.pid  fail2ban.sock

And if you put selinux in permissive mode....

[root at f18x fail2ban]# pwd
/var/run/fail2ban
[root at f18x fail2ban]# ls
[root at f18x fail2ban]# setenforce 0
[root at f18x fail2ban]# systemctl start fail2ban
[root at f18x fail2ban]# ls
fail2ban.pid  fail2ban.sock

So it is running with selinux placed in permissive mode.....
