[Fail2ban-users] Failed to start jail ... action 'iptables-multiport': [Errno 22] Invalid argument

[Dave C. <fai...@da...>]

I've got fail2ban working well on one of my boxes and it's really helpful.  I'm having trouble getting it running on a second Arch linux box.  Here's what I see in the log:

dave@apollo ~/Downloads % sudo tail /var/log/fail2ban.log

That last line, I get the same error no matter what jail(s) I enable.  None of them are working.

Searching the web has not helped me track this down.  I found this thread (https://github.com/fail2ban/fail2ban/issues/687) but don't understand it.

Any help would be appreciated.  Thanks.  -Dave
