perfSONAR User Q&A and Other Discussion

["Benjamin Modra" <>]

Hi,

 As far as I know , the CL-MP supports measurements for ping, traceroute, OWAMP and BWCTL.

 First, I installed bwctl,owamp and perfsonar-clmp-2.1-1 on two of my computers ,then test and get success echo from the service on my computers.

But when I make a bwctl request to one of my computer, I got a error.mp.clmp.exec response with CLMP service information.

The request in Section 1 and the response in Section 2.

 If anyone has any idea on how to do that or how to fix the error another way, I'm all ears.



Thank you very much,
