perfSONAR User Q&A and Other Discussion

[Alex Hsia <>]

I've been encountering problems with my perfSONAR node since I've transitioned to a Debian O/S.  External partners are having difficulty scheduling tests via pscheduler.  Here's the output from a pscheduler troubleshooting run;

alex@sdmz-perfsonar-40g:~$ pscheduler troubleshoot nettest.boulder.noaa.gov

Where should I look next to troubleshoot?
