Subversion Repositories configs

#

# WARNING: heavily refactored in 0.9.0 release.  Please review and

#          customize settings for your setup.

#

# Changes:  in most of the cases you should not modify this

#           file, but provide customizations in jail.local file,

#           or separate .conf files under jail.d/ directory, e.g.:

#

# HOW TO ACTIVATE JAILS:

#

# YOU SHOULD NOT MODIFY THIS FILE.

#

# It will probably be overwritten or improved in a distribution update.

#

# Provide customizations in a jail.local file or a jail.d/customisation.local.

# For example to change the default bantime for all jails and to enable the

# ssh-iptables jail the following (uncommented) would appear in the .local file.

# See man 5 jail.conf for details.

#

# [DEFAULT]

# bantime = 3600

#

# [sshd]

# enabled = true

#

# See jail.conf(5) man page for more information

# Comments: use '#' for comment lines and ';' (following a space) for inline comments

[INCLUDES]

#before = paths-distro.conf

before = paths-fedora.conf

# The DEFAULT allows a global definition of the options. They can be overridden

# in each jail afterwards.

[DEFAULT]

#

# MISCELLANEOUS OPTIONS

#

# "ignoreip" can be an IP address, a CIDR mask or a DNS host. Fail2ban will not

# ban a host which matches an address in this list. Several addresses can be

# defined using space separator.

ignoreip = 127.0.0.1/8

# External command that will take an tagged arguments to ignore, e.g. <ip>,

# and return true if the IP is to be ignored. False otherwise.

#

# ignorecommand = /path/to/command <ip>

ignorecommand =

# "bantime" is the number of seconds that a host is banned.

bantime  = 600

# A host is banned if it has generated "maxretry" during the last "findtime"

# seconds.

findtime  = 600

# "maxretry" is the number of failures before a host get banned.

maxretry = 5

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

# Available options are "pyinotify", "gamin", "polling", "systemd" 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.

# systemd:   uses systemd python library to access the systemd journal.

#              Specifying "logpath" is not valid for this backend.

#              See "journalmatch" in the jails associated filter config

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

#              pyinotify, gamin, polling.

#

# Note: if systemd backend is choses as the default but you enable a jail

#       for which logs are present only in its own log files, specify some other

#       backend for that jail (e.g. polling) and provide empty value for

#       journalmatch. See https://github.com/fail2ban/fail2ban/issues/959#issuecomment-74901200

backend = auto

# "usedns" specifies if jails should trust hostnames in logs,

#   warn when DNS lookups are performed, or ignore all hostnames in logs

#

# yes:   if a hostname is encountered, a DNS lookup will be performed.

# warn:  if a hostname is encountered, a 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.

usedns = warn

# "logencoding" specifies the encoding of the log files handled by the jail

#   This is used to decode the lines from the log file.

#   Typical examples:  "ascii", "utf-8"

#

#   auto:   will use the system locale setting

logencoding = auto

# "enabled" enables the jails.

#  By default all jails are disabled, and it should stay this way.

#  Enable only relevant to your setup jails in your .local or jail.d/*.conf

#

# true:  jail will be enabled and log files will get monitored for changes

# false: jail is not enabled

enabled = false

# "filter" defines the filter to use by the jail.

#  By default jails have names matching their filter name

#

filter = %(__name__)s
