# DEV Notes:

|
#
|
||||||
|
# This filter matches the authorization failures of Apache. It takes the log messages
|
||||||
|
# from the modules in aaa that return HTTP_UNAUTHORIZED, HTTP_METHOD_NOT_ALLOWED or
|
||||||
|
# HTTP_FORBIDDEN and not AUTH_GENERAL_ERROR or HTTP_INTERNAL_SERVER_ERROR.
|
||||||
|
#
|
||||||
|
# An unauthorized response 401 is the first step for a browser to instigate authentication
|
||||||
|
# however apache doesn't log this as an error. Only subsequent errors are logged in the
|
||||||
|
# error log.
|
||||||
|
#
|
||||||
|
# Source:
|
||||||
|
#
|
||||||
|
# By searching the code in http://svn.apache.org/viewvc/httpd/httpd/trunk/modules/aaa/*
|
||||||
|
# for ap_log_rerror(APLOG_MARK, APLOG_ERR and examining resulting return code should get
|
||||||
|
# all of these expressions. Lots of submodules like mod_authz_* return back to mod_authz_core
|
||||||
|
# to return the actual failure.

# Note that URI can contain spaces.

# Regarding the multiline regex:
|
||||||
|
#
|
||||||
|
# There can be a nunber of non-related lines between the first and second part
|
||||||
|
# of this regex maxlines of 10 is quite generious.
|
||||||
|
#
|
||||||
|
# Note the capture __connid, includes the connection ID, used in second part of regex.
|
||||||
|
#
|
||||||
|
# The first regex is commented out (but will match also), because it is better to use
|
||||||
|
# the host from "end connection" line (uncommented above):
|
||||||
|
# - it has the same prefix, searching begins directly with failure message
|
||||||
|
# (so faster, because ignores success connections at all)
|
||||||
|
# - it is not so vulnerable in case of possible race condition
|
||||||
|
#
|
||||||
|
# Log example:
|
||||||
|
# 2016-10-20T09:54:27.108+0200 [initandlisten] connection accepted from 127.0.0.1:53276 #1 (1 connection now open)

# time bans for ip addresses that get banned by fail2ban multiple times.
|
||||||
|
#
|
||||||
|
# Reasons to use this: block very persistent attackers for a longer time,

# over again.

# This jail is only useful if you set the 'findtime' and 'bantime' parameters
|

|
# in jail.conf to a higher value than the other jails. Also, this jail has its
|

|
# drawbacks, namely in that it works only with iptables, or if you use a
|
||||||
|
# different blocking mechanism for this jail versus others (e.g. hostsdeny
|
||||||
|
# for most jails, and shorewall for this one).
