perfSONAR User Q&A and Other Discussion

[Michael Thomas <>]

I recently set up a perfsonar server and configured it to run throughput 
tests with two other sites in our group.  The iperf3 tests from my site 
to the remote locations works fine, but all incoming tests fail, with 
the following results in my pscheduler logs:

Mar  7 12:19:48 perfsonar.ligo-la.caltech.edu journal: runner INFO 
12832: Running

Testing from the CLI shows an authorization failure:

Error from perfsonar.ligo-wa.caltech.edu:
  iperf3 output has neither 'sum_sent' nor 'sum' field, and one of them 
is required

        "end":  {
        },
        "error":        "test authorization failed"
  }

How can I further debug this authorization failure?

I will also note that this looks suspiciously like the same issue 
described in a previous post, but killing the rogue iperf3 process does 
not allow subsequent tests to work.
