perfSONAR User Q&A and Other Discussion

[Ignacio Peluaga Lozada <>]

Hi Mark,

thanks a lot, that option will come in handy for us.

I checked the Github issue and saw this feature will be part of the next 
feature release, when can we expect that?

Thanks.

Regards,
Ignacio

I would like to ask if it is possible to run pScheduler's latency task when 
it sits behind NAT. More specifically, I am using the perfSONAR Docker 
testpoint on a Linux VM.

I learnt it's possible to use twping (whose option '-Z' allows the NAT 
environment) instead of the default owping since perfSONAR 4.1. The following 
command works fine:

        twping -Z psb01-gva.cern.ch

I understand pScheduler's '--tool' option can be used to select twping but 
still, I get no measurements. I run it in this way:

        pscheduler task --tool twping latency --dest psb01-gva.cern.ch

…

        Run did not complete: Failed

The failure is caused by a bug that crept in  during 4.3 development and 
managed to slip through testing.  I’ve fixed it and will get a patch out 
early next week.   You mentioned that your system is 4.2.4, but this bug 
wasn’t present there.  You probably auto-upgraded to 4.3.

As far as the -Z is concerned, I’ve opened an issue on that:  
https://github.com/perfsonar/pscheduler/issues/1082.  If there are no side 
effects of putting that switch on by default, I’ll slip it in with the next 
bugfix.  If there are, we’ll need to add a switch to the latency test to 
enable that behavior and will have it out in the next release.  (That change 
is kind of a big deal if we have to make it.)
