perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi,

From the logs provided, it looks like BWCTL is not able to complete the ping test. Specifically it looks like its complaining about not being able to bind to the local interface (see the  "bind: Cannot assign requested address” buried in the log output ). Is 10.177.47.206  the correct address?

Thanks,

Andy

Hello,

I have installed CentOS with PerfSONAR onto two different computers in order
to test end-to-end monitoring however none of the tests are working. There
are no results being acquired from the tests. After looking through the log
files the error seems to be writing metadata. I am at a loss of how to fix
this problem, any help would be great.

Thanks,
Tyler
