perfsonar development work

[Joe Metzger <>]

Nina,
I am running this against a pre-release version of the Perfsonar-PS MA.
There is no Tomcat or Axis in the picture on the server side, but I
do have copious log files.

There are no firewalls in between the server and the client.

I will see if I can track down and isolate the packet stream and the
logs from a single failed connection attempt if I have time later today.
