fail2ban
Hi,
I realise that one can simply start fail2ban and then it will insert its
own ruleset before shorewall''s ruleset. Are there subscribers to this
list having alternative (and probably better) ways to use both fail2ban
and shorewall?
Thanks,
Mark

I have configured dovecot with
auth_failure_delay = 10 secs
I hope that before the 10 sec are over, dovecot will have logged about
the failed login attempt, and fail2ban will have blocked the ip by then.

iptables - how to block established connections with fail2ban?
I am working to a CentOS 6 server with nonstandard iptables system
without rule for ACCEPT ESTABLISHED connections. All tables and chains
empty (flush by legacy custom script) so only filter/INPUT chain has
rules (also fail2ban chain):
Chain INPUT (policy ACCEPT)
target prot opt source destination
f2b-postfix tcp -- 0.0.0.0/0 0.0.0.0/0
ACCEPT all --

You may have to ensure the ipset is present before referencing it in iptables,
for example, Redhat-alikes will have an ipset init script that operates in
exactly the same way as...
