Не получается настроить fail2ban на Proxmox 8.1

Question

Создаю базовые настройки, пытаюсь проверить командой fail2ban-client -v status sshd и fail2ban-regex /var/log/daemon.log /etc/fail2ban/filter.d/proxmox.conf, но везде вылезает ошибка:

 ``fail2ban-client -v status sshd`

При попытке запустить и проверить вылезает следующее:

в файле /etc/fail2ban/jail.local привести секцию sshd к такому виду:

[sshd]
enabled = true
backend = systemd
port = ssh
logpath = %(sshd_log)s

сохранить и перезапустить демона:

$ sudo service fail2ban restart

посмотреть состояние демона:

$ sudo service fail2ban status
