I am conducting a research project and have been trying to use the perfSONAR trace tool. The machine I am using for the tests has all UDP ports blocked, and as far as I have found in the perfSONAR documentation, trace runs exclusively on UDP. 

I have not found anything in the documentation to suggest that this is possible, but is there a way to force the trace tool to use an ICMP protocol rather than UDP?

 

The trace test has a probe-type parameter (and a matching switch for the CLI) that can be icmp, udp or tcp:

 

pscheduler task trace --probe-type icmp --dest www.perfsonar.net

 

The traceroute tool supports all three, but I did just notice a bug in the pScheduler plugin that doesn’t set the right permissions to do TCP.  I’ve opened a ticket on that (https://github.com/perfsonar/pscheduler/issues/1324) and we’ll have a fix for that out in the next release.
