How do I create regex for fail2ban.
Nothing goes to jail

Had a google and a look at:
http://linux.die.net/man/1/fail2ban-regex
http://www.fail2ban.org/wiki/index.php/Talk:MANUAL_0_8

but can't figure it out.

Here's what I have in jail.conf


[ssh-iptables]

<snip>
timeregex = S{3}s{1,2}d{1,2} d{2}:d{2}:d{2}
timepattern = %%b %%d %%H:%%M:%%S
failregex = pam_unix(sshd:auth): authentication failure

</snip>

A paste of some login attempts:
http://fpaste.org/paste/8177

the only other jail enabled is ssh-tcpwrappers

A factor could be down to the various *logs being out of sync,
"So, check that all your logs are synchronized"
http://www.fail2ban.org/wiki/index.php/FAQ_english#Fail2ban_is_running_but_not_banning_SSH_bruteforce

But have no idea how to check log timestamps with logger.
