Hello, I recently upgraded my PC from F26 to F27, and noticed that fail2ban was not adding the configured chains to iptables. This worked fine at F26. There are no error messages in the log files (dmesg, /var/log/messages, /var/log/fail2ban.log). I have tried disabling SELinux, then restarting fail2ban but the chains still do not appear. I do not use firewalld so removed the fail2ban-firewalld package. I set the fail2ban log level to debug, and that showed the relevant iptables commands that would add the chains, but otherwise gave no indication of any error. (I used the logged iptables commands to manually add the chains, and all the commands worked fine.) If I log (using logger) appropriate log messages - such as an SSH failed authentication attempt - then that particular chain does appear in iptables. If I unban the logged IP address, then the chain remains in iptables. If I restart fail2ban, then the chain is no longer in iptables. I'm now a bit stumped as to what might be the problem. Anyone any ideas?
