# Fail2Ban configuration file.

# To avoid merges during upgrades DO NOT MODIFY THIS FILE

# The DEFAULT allows a global definition of the options. They can be overridden
# in each jail afterwards.

# "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.

# "usedns" specifies if jails should trust hostnames in logs,
#   warn when reverse DNS lookups are performed, or ignore all hostnames in logs
#
# yes:   if a hostname is encountered, a reverse DNS lookup will be performed.
# warn:  if a hostname is encountered, a reverse DNS lookup will be performed,
#        but it will be logged as a warning.
# no:    if a hostname is encountered, will not be used for banning,
#        but it will be logged as info.
