Hi,
I have fail2ban up and running on my Fedora 15.
root 1026 0.0 0.3 189936 6724 ? S 13:52 0:00
/usr/bin/python /usr/bin/fail2ban-server -b -s
/var/run/fail2ban/fail2ban.sock -x
I use it for banning IPs that try to connect to my host via SSH.
Here's below is a snip of jail.local:
--- [jail.local] ---
[ssh-iptables]
enabled = true
filter = sshd
action = iptables[name=SSH, port=ssh, protocol=tcp]
sendmail-whois[name=SSH, dest=sguazt, sender=fail2ban@localhost]
logpath = /var/log/secure
maxretry = 3
--- [/jail.local] ---
However I can't see it in the iptables status (like I could until Fedora 14).
So I think it is not working properly.
Here's my iptables status:
--- [iptables status] ---

Any idea?
Thank you very much!
