Re: [Fail2ban-users] fail2ban not logging

[Davide P. <per...@dp...>]

I don't think that log rotations can be the cause since there is no log 
at all on

/var/log/fail2ban.log

I don't see any log on that file. I tried with tail -f on that file
while an IP is banned and no log is written.

Thanks.
