 #    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 
 # ...
