 #  MENTIODNS : Check for lying DNS (France)  #
 #--------------------------------------------#
-sacha
+#  Version 1.6 - conf file                   #
-sacha
+#  Version 1.5 - test Dig resolving          #
 #  Version 1.4 - Socat SSL sending results   #
 #  Version 1.3 - tld optioN                  #
-sacha
+#  Version 1.2 - Round robin on DNS_ISP_LIST #
-sacha
+#		 For each request	     #
-sacha
+#  Version 1.1 - Allow resume on basename    #
 #  Version 1.0 - Parallel process with DIG   #
 #--------------------------------------------#
-sacha
+# (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
-sacha
+# 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)
-sacha
+# 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
-sacha
+# Diff ip from a domain name are in $DIFF_LOG

-sacha
+# 1st launch creating config file

+# Copy generated certificates:
 # FILENAME=mentio_ssl-server
