How to configure fail2ban file? I installed fail2ban but When I enter fail2ban-client status in the Linux terminal, I get the following warnings: fail2ban.configreader [1616]: ERROR Found no accessible config files for 'filter.d/murmur' under /etc/fail2ban fail2ban.configreader [1616]: ERROR No section: 'Definition' fail2ban.configreader [1616]: ERROR No section: 'Definition' fail2ban.configreader [1616]: ERROR No section: 'Definition' fail2ban.configreader [1616]: ERROR No section: 'Definition' fail2ban.configreader [1616]: ERROR No section: 'Definition' fail2ban [1616]:ERROR Failed to access socket path: /var/run/fail2ban/fail2ban.sock. Is fail2ban running? By the way, I know there is a problem with the configuration, but I do not know how to configure it

I solved the problem. The problem was that the fail2ban folder was empty in the path / etc / fail2ban. I downloaded the pack from the official site fail2ban.org and transferred the contents of this pack to / etc / fail2ban.
