[Ali S. <ash...@gm...>]

Hi
I reload fail2ban via: sudo fail2ban-client reload
with jail.local:

[ssh-iptables]
enabled  = true
filter   = sshd
action   = iptables[name=SSH, port=ssh, protocol=tcp]
logpath  = /var/log/auth.log
maxretry = 5


But I recieved error message:
ERROR  NOK: ('ssh-iptables',)

Please help me.
