Запускается если обратно выключить enabled = false в Jails но тогда не блокирует ничего и работает в холостую.

Содержимое jail.conf точно как тут https://github.com/fail2ban/fail2ban/bl ... /jail.conf

fail2ban - настройки стоит *5 раз для перебора вроде по умолчанию.
Можно настроить под свой вкус.

* - но возможно и 3, могу ошибаться

p.s. Рекомендую проверить секцию.

Code: Select all

[sshd]


port     = ssh
filter   = sshd
logpath  = %(ssh_log)s
maxretry = 3

Как я понял так он ругаеться на правила в jail.conf так как там все сервисы, но я пробовал оставлял в нем только sshd но не помогло

если центос7.2 fail2ban есть косяк в fail2ban-server-0.9.3-1.el7.noarch он не работает должным оброзом.
па пробую ниже версию поставить.

У меня как раз он и есть

CentOS Linux release 7.2.1511 (Core)

fail2ban-server-0.9.3-1.el7.noarch
