# MENTIODNS : Check for lying DNS (France) #
#--------------------------------------------#
# Version 1.6.1 date bug
# Version 1.6 - conf file #
# Version 1.5 - test Dig resolving #
# Version 1.4 - Socat SSL sending results #
# Version 1.3 - tld optioN #
# Version 1.2 - Round robin on DNS_ISP_LIST #
# For each request #
# Version 1.1 - Allow resume on basename #
# Version 1.0 - Parallel process with DIG #
#--------------------------------------------#
# (c) Sacha at Aquilenet.fr part of FFDN.org #
#--------------------------------------------#
# This shity script intend to bruteforce the ISP lying DNS Servers to identify which one
# is going on Ministry of Interior Blocking page and compare the IP result from your favorite DNS server
# Use this script with the following parameters
# $1 MODE: client server local
# $2 File source: list of domain names whithout tld
# $3 tld: com, org, ...
# $4 count number (if none from zero or from count file based on file name)
# If you relanch the script it will check if it has a counter for the given file to resume
# Blacklisted sites in $BLACKLIST_LOG file
# Diff ip from a domain name are in $DIFF_LOG
# 1st launch creating config file
# Copy generated certificates:
# FILENAME=mentio_ssl-server
# openssl genrsa -out $FILENAME.key 1024
# openssl req -new -key $FILENAME.key -x509 -days 3653 -out $FILENAME.crt
# cat $FILENAME.key $FILENAME.crt >$FILENAME.pem
# FILENAME=mentio_ssl-client
# ...
