# ripecheck.tcl Version: 3.6 Author: Stefan Wold <ratler@stderr.eu>
###
# Info:
# This script check unresolved ip addresses against a RIPE database
# and ban the user if the country match your configured top domains.
# Features:
# * Configuration through dcc console
# * Per channel settings
# * Can handle top domain banning for name based hosts
# * Custom bantime
# * Support extra resolving for domains like info, com, net, org
# to find hosts that actually have an ip from a country
# you wish to ban.
# * Customizable ban messages with simple keyword support, see .help ripeconfig
# * Builtin help pages, see .help ripecheck or .help
# * !ripeinfo [#channel] <nick|host> to get verbose information from whois about the host
# * !ripeinfo and !ripecheck are available as public commands and through private
# /msg to the bot (if enabled)
# * Ban counter, number of times ripecheck have banned someone in the channel
# * !ripestatus [*|#channel] show settings and bancount stats for the channel
# * Whitelist mode. Only let hosts from a country specified by the TLD list
# enter the channel, everyone else get banned.
# * GeoIP from ipinfodb.com
# * !ripegeo [#channel] <nick|host> to get country, region, city, latitude,
# longitude and google map url. Available as public and private commands.
# * Ripecheck now support using GeoIP as primary ban method, if GeoIP fail ripecheck
# will automatically fall back using whois
# * !ripetld <tld>, !ripescan [channel] and !ripehelp
# * Support for two GeoIP backends, geotool and ipinfodb. Defaults to geotool.
# * New function to exclude hosts from being scanned using regexp matching. Useful for
# networks like UnderNET or other networks that use host hiding. A DNS may automatically
# resolve unresolable hosts giving a false positive. See help .ripeconfig.
#
###
# Information regarding ipinfodb.com usage:
#
# To enable GeoIP support registration for an API key with ipinfodb.com is required.
# Registration is free, register here: http://www.ipinfodb.com/register.php
###
# Require / Depends:
# TCL >= 8.5
# tcllib >= 1.10 (http://www.tcl.tk/software/tcllib/)
###
# Usage:
# Load the script and change the topdomains you
# wish to ban.
#
# For help and available commands see:
# .help ripecheck
#
###
# Public channel commands:
# !ripecheck <nick|host>
# !ripeinfo [#channel] <nick|host>
# !ripegeo [#channel] <nick|host>
# !ripestatus [*|#channel]
# !ripetld <tld>
# !ripescan [channel]
# !ripehelp
# Private msg commands:
# !ripecheck <host>
# !ripeinfo <host>
# !ripegeo <host>
# !ripetld <tld>
# !ripehelp
###
# Tested:
# eggdrop v1.6.19 GNU/Linux with tcl 8.5 and tcllib 1.10
# eggdrop v1.6.20 GNU/Linux with tcl 8.5 and tcllib 1.12
# - Known issues
# - There is a known bug in 1.6.20 with the new notifier code
# and vwait that cause segmentation fault after running
# the bot for a while. Workaround right now is to disable
# the new code by changing #ifdef HAVE_TCL_SETNOTIFIER 1 to
# #undef HAVE_TCL_SETNOTIFIER in config.h and recompile your eggdrop.
###
# BUGS?!
# If you discover any problems please send an e-mail
# to ratler@stderr.eu with as detailed information as possible
# on how to reproduce the issue.
