Cant enable fail2ban jail sshd

When enabled sshd jail i see Starting fail2ban: ERROR NOK: ("Failed to initialize any backend for Jail 'sshd'",) ERROR NOK: ('sshd',) In logs : ERROR Backend 'systemd' failed to initialize due to No module named systemd ERROR Failed to initialize any backend for Jail 'sshd'

Centos 6.7 no have systemd module . CentOS 6.7, python 2.6

Solution

  • Just replace in you jail config backend to auto From

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

    To 

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

    And restart service service fail2ban restart
