# Example configuration file for ddos-mitigator.sh.
# PLEASE TAKE CARE not to put any whitespace around the '=' signs, as this file is directly sourced by the script
# file and this needs to conform to the BASH syntax. Also, make sure to declare the COUNTRIES variable with the
# correct array syntax: COUNTRIES=("AA" "BB" "CC"), or to comment it out altogether.
# The path to the GeoIP2 database file (must be either country or city database). This parameter is mandatory. If it is
# not specified here, it must be given on the command line (through the -d option).
DATABASE_FILE="/path/to/geoip/country-or-city-database.mmdb"
# Enable the autopilot for automatically banning IP addresses of the desired countries (see also COUNTRIES option).
# Only ban IP addresses with at least AUTOPILOT current connections. If the value is not specified or 0, don't
# automatically ban IP addresses, but run in interactive mode.
AUTOPILOT="0"
# Defines the subnet size in bytes to be analyzed. Valid values are:
# - 8 for class A networks (X.0.0.0/8)
# - 16 for class B networks (X.X.0.0/16)
# - 24 for class C networks (X.X.X.0/24)
# - 32 for class D networks (X.X.X.X/32)
# If not specified, run in interactive mode and prompt for the netmask size.
NETMASK="8"
# The country-codes to block as an array. Defaults to "CN" (China).
#COUNTRIES=("CN" "HK" "TW")
# Specify the JAIL to use for banning the IP addresses. Defaults to 'apache-auth'.
#JAIL="apache-auth"
# The desired port to monitor. Defaults to 443 (https).

# Try and prevent apache overloads by banning IP addresses that have (too) #
# many open connections. #
# This script uses ss to determine the connections to a configurable port #
# on the host machine and provides automated GeoIP information retrieval based #
# the address or the /24-, /16- or /8-subnet thereof. A GeoIP city- or country #
# database must be installed separately and is provided to the script via a #
# command line parameter. #
# Addresses (or subnets) are presented to the user in order of descending #
# connection count. For each address (or subnet), the user can choose to ban #
# or ignore it. Addresses (or subnets) chosen to be banned will be blocked by #
# a configurable jail of fail2ban. #
# This script uses netstat to determine the connections to the HTTPS port of #
# the host machine and provides automated whois information retrieval based on #
# the address or the /24-, /16- or /8-subnet thereof. Addresses (or subnets) #
# are presented to the user in order of descending connection count. For each #
# address (or subnet), the user can choose to ban or ignore it. Addresses (or #
