# /etc/fail2ban/filter.d/nginxrepeatoffender.conf
|
|
# Fail2Ban Blacklist for Repeat Offenders of Nginx (filter.d)
|
|
#
|
|
# Author: Mitchell Krog <mitchellkrog@gmail.com>
|
|
# Version: 1.1
|
|
#
|
|
# Add on for Nginx Ultimate Bad Bot blocker
|
|
# GitHub: https://github.com/mitchellkrogza/nginx-ultimate-bad-bot-blocker
|
|
#
|
|
# Tested On: Fail2Ban 0.9.3
|
|
# Server: Ubuntu 16.04
|
|
# Firewall: IPTables
|
|
#
|
|
# Dependancies: requires nginxrepeatoffender.conf in /etc/fail2ban/action.d folder
|
|
# requires jail settings called [nginxrepeatoffender]
|
|
# requires nginx.repeatoffender file in /etc/fail2ban
|
|
# create with sudo touch /etc/fail2ban/nginx.repeatoffender
|
|
# chmod +x /etc/fail2ban/nginx.repeatoffender
|
|
#
|
|
# Drawbacks: Only works with IPTables
|
|
#
|
|
# Based on: The Recidive Jail from Fail2Ban
|
|
# This custom filter and action will monitor your Nginx logs and perma-ban
|
|
# any IP address that has generated far too many 444 or 403 errors over a 1 week period
|
|
# and ban them for 1 day. This works like a charm as an add-on for my Nginx Bad
|
|
# Bot Blocker which takes care of generating the 444 or 403 errors based on the extensive
|
|
# list of Bad Referers, Bots, Scrapers and IP addresses it covers.
|
|
# See - https://github.com/mitchellkrogza/nginx-ultimate-bad-bot-blocker for more info
|
|
#
|
|
# This custom action requires a custom jail in your
|
|
# jail.local file for Fail2Ban
|
|
#
|
|
# Your jail file would be configured as follows
|
|
#
|
|
# [nginxrepeatoffender]
|
|
# enabled = true
|
|
# logpath = %(nginx_access_log)s
|
|
# filter = nginxrepeatoffender
|
|
# banaction = nginxrepeatoffender
|
|
# bantime = 86400 ; 1 day
|
|
# findtime = 604800 ; 1 week
|
|
# maxretry = 20
