Hi,
I'm using fail2ban-0.9.3 on fedora22 and have configured it with
firewalld and ipset. I'm more familiar with iptables, not this new
firewalld layout, so I'm really not sure how to tell if it's working
properly.

I have a postfix-sasl jail configured as such:

[postfix-sasl]
#port     = smtp,465,submission
port     = smtp,587,submission
logpath  = %(postfix_log)s
enabled  = true
logencoding=utf-8

/var/log/fail2ban.log shows these entries:

fail2ban.filter         [19398]: INFO    [postfix-sasl] Found 12.234.0.173
fail2ban.actions        [19398]: NOTICE  [postfix-sasl] Ban 12.234.0.173

ipset list shows me:

Name: fail2ban-postfix-sasl
Type: hash:ip
Revision: 4
Header: family inet hashsize 1024 maxelem 65536 timeout 5200
Size in memory: 1856
References: 1
Members:
12.234.0.173 timeout 4068
179.189.205.12 timeout 152
184.2.47.206 timeout 390
113.69.178.121 timeout 1522

Does this say that 12.234.0.173 is indeed currently blocked on port
589 for the next 4068 seconds?

firewalld is running, but I don't know how to produce a list of all
IPs that are currently being blocked. "iptables -nL", as I usually
would run, shows there are no entries for any of the chains that are
listed (except for 192.168.122.0/24 as part of virbr0). Does that mean
the rules aren't being added properly by fail2ban?
