Esta mañana al resetear el servicio fail2ban me he encontrado con esto:

service fail2ban status

El Workaround que he aplicado es establecer en polling el backend para averiguar las modificaciones en ficheros de forma que no utilice librerías externas.

(editar jail.conf)

# "backend" specifies the backend used to get files modification.

# Available options are "pyinotify", "gamin", "polling" and "auto".

# This option can be overridden in each jail as well.

#

# pyinotify: requires pyinotify (a file alteration monitor) to be installed.

#            If pyinotify is not installed, Fail2ban will use auto.

# gamin:     requires Gamin (a file alteration monitor) to be installed.

#            If Gamin is not installed, Fail2ban will use auto.

# polling:   uses a polling algorithm which does not require external libraries.

# auto:      will try to use the following backends, in order:

#            pyinotify, gamin, polling.

backend = polling
