There are two scripts. They both require sudo privileges to run (e.g. sudo ping-vs-tcp.pl) and have an option --prot <4|6> for IPv4 vs IPv6. Help is available via the --help option. The output in both cases goes to STDOUT, e.g. sudo ping-vs-tcp.pl --prot 4 | tee pg-v4-sl.txt (if you are using ping-vs-tcp-ps then change pgto pg to ps, for Chinese MA changesl change sl to ch, for Unimas MA change to my, Thailand change to th). IPv4 measurements in both cases take about 7 hours. You can obtain a copy of each of the scripts from cottrell@slac.stanford.edu
