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 pg to ps(short for PingER) to ps (short for perfSONAR), for Chinese MA change sl sl (short for SLAC) to ch (short for China), 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
