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 ps, for Chinese MA changesl 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
- ping-vs-tcp-ps.pl. This requires you to provide a configuration file (e.g. ping-vs-tcp-ps.pl –conf sq-v4-lc.cf | tee ps-v4-ch.txt for Chinese MA.
- The configuration files are available at:
- ping-vs-tcp.pl. This gets its configuration by using wget to get the SLAC PingER database of hosts, so there is no configuration option (–conf). To run use for example use sudo ping-vs-tcp.pl --prot 4 | tee pg-v4-sl.txt.
The form of the config file is <source of target hosts, e.g. lc for Les, sq for Saqib>-<IPv 4 or 6>-<site of MA, sl for SLAC, ch for China, th for Thailand, my for Malaysia>.<cf=configuration file>
The form of the file STDOUT is sent to is <source of target, i.e. pg for PingER and ps for perfSONAR>-<site of MA, sl for SLAC, ch for China, th for Thailand, my for Malaysia>.txt
Then proceed as follows for example:
- grep summary pg-v4-sl.txt >! pg-v4-ch.csv
- then load pg-v4-sl.csv into Excel and analyse.
