Re: run firehol before fail2ban

Hi Phil,
thank you for your answer!

Yes I run fail2ban from package and firehol from git source. The 
standard firehol from package is version 2.0*, and with that I think I 
can not play with iptrap etc. Anyway I had try before native firehol 
from ubuntu package and there I had the same problem. It starts way to 
late, so it deletes fail2ban. Ok I have to say to, that I need it with a 
special config, so that it start only if a interface is up (from a VM).

For this situation I guess a backport solution or a init script will not 
really help. It would be great o have an option in firehol where I can 
run post commands after a firewall is establish, so I could say run me 
/service fail2ban restart/ after, but I think it is not integrated.

I need to try whats happen, if I remove the fail2ban init script and 
replace it with a systemd service. Maybe the update process will still work.
