无法启用fail2ban监狱sshd

Question

启用 sshd监狱后，我Starting fail2ban: ERROR NOK: ("Failed to initialize any backend for Jail 'sshd'",) ERROR NOK: ('sshd',) 在日志中看到： ERROR Backend 'systemd' failed to initialize due to No module named systemd ERROR Failed to initialize any backend for Jail 'sshd'

Centos 6.7 没有 systemd 模块。CentOS 6.7、Python 2.6

Answer 1

只需将监狱配置后端替换为auto From

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

到

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

并重启服务service fail2ban restart
