Fail2ban not working on FC9

I installed Fail2ban on FC9 as per the how to on

But it doesn't seem to block the authentication failure attempt even when I do a fail2ban-regex on the /var/log/messages it doesn't detect the auth failures although there are failures on it. Any idea why this is happening? I use this for SSHD auth failure events.

Below is my jail.conf

# "ignoreip" can be an IP address, a CIDR mask or a DNS host. Fail2ban will not
# ban a host which matches an address in this list. Several addresses can be
# defined using space separator.
ignoreip =

# "bantime" is the number of seconds that a host is banned.
bantime = 7200

# A host is banned if it has generated "maxretry" during the last "findtime"
# seconds.
findtime = 600

# "maxretry" is the number of failures before a host get banned.
maxretry = 3

# "backend" specifies the backend used to get files modification. Available
# options are "gamin", "polling" and "auto". This option can be overridden in
# each jail too (use "gamin" for a jail and "polling" for another).
# gamin: requires Gamin (a file alteration monitor) to be installed. If Gamin
# is not installed, Fail2ban will use polling.
# polling: uses a polling algorithm which does not require external libraries.
# auto: will choose Gamin if available and polling otherwise.
backend = auto

# This jail corresponds to the standard configuration in Fail2ban 0.6.
# The mail-whois action send a notification e-mail with a whois request
# in the body.


enabled = true
filter = sshd
action = iptables[name=SSH, port=ssh, protocol=tcp]
logpath = /var/log/secure
maxretry = 3

fail2ban is checking /var/log/secure instead of /var/log/messages.

OK.. I changed it to /var/log/messages.. Will get back to you if anything happens.

I did as what falko told me and it seems to work now ..when I do a fail2ban-regex it does capture the auth fail events. thanks falco the correction is

point log to be scanned to /var/log/messages
