Hi all,

Is it possible to trap this problem and flag it in a more visible way?

endpoint

Howdy John-Paul;

So I believe there are two issues here. I can offer the technical solution,
which may be superseded by Layer8/9 issues that others (from Internet2 or the
Global NOC) will need to speak to:

- The BWCTL server software on machine in question
(bwctl.atla.net.internet2.edu) is old, and not behaving in a way consistent
with what the new BWCTL on version 3.4 of perfSONAR would expect. I can’t
say for certain, but I would guess its 1.4.x vs 1.5.y.

- The BWCTL server is not a part of the new list related to the Internet2
Performance Service that support ad-hoc testing
(http://www.internet2.edu/products-services/performance-analytics/performance-assurance-service/#features-adhoc).
This appears to be an orphaned server that needs some TLC, or to be put out
of its misery.

I would suggest maybe trying one of the other ad-hoc servers in the meantime,
or you can follow the procedure to be granted a golden ticket to test to the
other resources that are not public.

Hope this helps;

Thanks;
