I was told not to modify any *.conf file, no i created an empty jail.local file, then paste this in:
[sshd]
port = ssh
logpath = %(sshd_log)s
backend = %(sshd_backend)s
maxretry = 3
enable = true
after reboot only getting this error message:
"[519]: ERROR Failed during configuration: Have not found any log file for sshd jail"
Apr 30 14:06:54 koha-01 systemd[1]: fail2ban.service: Main process exited, code=exited, status=255/EXCEPTION
Apr 30 14:06:54 koha-01 systemd[1]: fail2ban.service: Failed with result 'exit-code'.
debian 12.5 minimal with ssh
apt install fail2ban nano /etc/fail2ban/jail.conf , find [sshd], add maxretry =3, enable = true reboot now.
everything is working.
