perfSONAR User Q&A and Other Discussion

pscheduler needs to connect on port 443, and then will launch bwctl as needed.

I tried that command but it didn’t work.

^C

So if pScheduler fails to connect on 443 is it supposed to try 4823?

It should work fine. What command are you using?

For example, this works from a 4.0 host to a 3.5 host:

pscheduler task throughput --dest receive_host

Hi,

I installed the perfsonar-tools package for pS 4.0 but I’m unable to get pScheduler to test with BWCTL.  I thought there were tool plugins for pScheduler to support this.  Are they available in the perfsonar-tools package?

Thanks,

George
