Hi,
from logwatch I saw this error :
ERROR Failed to execute ban jail ‘ssh-iptables’ action ‘iptables’ info ‘CallingMap({‘ipjailmatches’: <function <lambda> at 0x7f8e24d2b578>, ‘matches’: u’Jan 28 00:15:51 saic sshd[30705]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=ti0100a400-1587.bb.online.no user=root\n

To solve I follow this : https://github.com/fail2ban/fail2ban/issues/973
and than this : https://github.com/fail2ban/fail2ban/issues/878#issuecomment-65732113
Not necessarily… But if you will really stand-alone fail2ban, so download direct from github or checkout via git (from github). – master – https://github.com/fail2ban/fail2ban/archive/master.zip – debian – https://github.com/fail2ban/fail2ban/archive/debian.zip – repo – git://github.com/fail2ban/fail2ban.git
Hereafter unzip it and run install:
cd /tmp/f2b
?sudo? python setup.py install
So I reinstalled fail2ban, previous backup fine (/etc/fail2ban).
After installation I overwrote /etc/fail2ban with my previous file.
