d'oh me -- I've read your original incorrectly (that you applied patch
and it didn't help ;-)) .
Just out of "research" -- could you please run in shell all 3 commands
in a single line like
iptables -N fail2ban-proftpd; iptables -A fail2ban-proftpd -j RETURN; iptables
-I INPUT -p tcp -m multiport --dports ftp,ftp-data,ftps,ftps-data -j
fail2ban-proftpd
I would really not expect some out of order execution from Python's
os.system and it might be that real problem is buried deeper.
