Looking at the output, I think you've quoted the regex in your /root/test.conf as the "failrexex =" line is different in your two tests. Remove the quoting.



If only it were that simple. The file isn't quoted. Here's the exact contents, character for character:

[Definition]
failrexex =     .*<HOST>\#.*

ignoreregex =

I assume failrexex is a typo. Do you have an [Includes] section?

I wish. I cannot BELIEVE I missed that. What I put was a direct copy/paste. That's fixed now and it matches in the test sequence.

But something strange is going on. Fail2ban created the named-refused table in iptables just fine. But it is populated with a LOT of returns:

<non-F2B rule>
-A f2b-named-refused -j RETURN
-A f2b-named-refused -j RETURN
-A f2b-named-refused -j RETURN
-A f2b-named-refused -j RETURN
-A f2b-named-refused -j RETURN
-A f2b-named-refused -j RETURN
-A f2b-named-refused -j RETURN
-A f2b-named-refused -j RETURN
-A f2b-recidive -s 85.55.160.62/32 -j REJECT --reject-with icmp-port-unreachable

Why on earth do we need that many returns?

BTW I think you are cutting way too much from the posts that they are impossible to follow.


I will remember that. Sorry. I'm used to keeping emails small.
