# Fail2ban filter configuration for traefik :: auth
# used to ban hosts, that were failed through traefik
#
# Author: CrazyMax
#
# To use 'traefik-auth' filter you have to configure your Traefik instance to write
# the access logs as describe in https://docs.traefik.io/configuration/logs/#access-logs
# into a log file on host and specifiy users for Basic Authentication
# https://docs.traefik.io/configuration/entrypoints/#basic-authentication
#
# Example:
#
# version: "3.2"
#
# services:
#   traefik:
#     image: traefik:latest
#     command:
#       - "--loglevel=INFO"
#       - "--accesslog=true"
#       - "--accessLog.filePath=/var/log/access.log"
# #       - "--accessLog.filters.statusCodes=400-499"

[Definition]

# Parameter "method" can be used to specifiy request method
req-method = \S+
# Usage example (for jail.local):
#   filter = traefik-auth[req-method="GET|POST|HEAD"]

failregex = ^<HOST> \- <usrre-<mode>> \[\] \"(?:<req-method>) [^\"]+\" 401\b

ignoreregex =

# Parameter "mode": normal (default), ddos or aggressive
# Usage example (for jail.local):
#   [traefik-auth]
#   mode = aggressive
#   # or another jail (rewrite filter parameters of jail):
#   [traefik-auth-ddos]
#   filter = traefik-auth[mode=ddos]
#
mode = normal

# part of failregex matches user name (must be available in normal mode, must be empty in ddos mode, and both for aggressive mode):
usrre-normal = (?!- )<F-USER>\S+</F-USER>
usrre-ddos = -
usrre-aggressive = <F-USER>\S+</F-USER>
