Debian GNU/Linux 8.7 (jessie) ISPConfig 3.1.2 Just noticed fail2ban does not start. Server is installed following Perfect Server guide, and I just checkec the configuration files, they look to me identical to the ones in guide. Code: root@ispc5:/etc/fail2ban/filter.d# service fail2ban stop root@ispc5:/etc/fail2ban/filter.d# service fail2ban start root@ispc5:/etc/fail2ban/filter.d# service fail2ban status ● fail2ban.service - LSB: Start/stop fail2ban Loaded: loaded (/etc/init.d/fail2ban) Active: active (exited) since pe 2017-04-28 14:27:33 EEST; 2s ago Process: 19457 ExecStop=/etc/init.d/fail2ban stop (code=exited, status=0/SUCCESS) Process: 19485 ExecStart=/etc/init.d/fail2ban start (code=exited, status=0/SUCCESS) huhti 28 14:27:33 ispc5.antenniserveri.fi fail2ban[19485]: Starting authentication failure monitor: fail2banERROR Error in action definition iptables-multiport[name=dovecot-pop3imap, huhti 28 14:27:33 ispc5.antenniserveri.fi fail2ban[19485]: ERROR Errors in jail 'dovecot-pop3imap'.

Found it at last. One line had got an extra newline in the middle. I copypasted those lines, strange.
