perfSONAR User Q&A and Other Discussion

[Zhi-Wei Lu <>]

Hi all,

 

We are testing with the new perfSonar 3.4rc2 and we encountered a few bumps along the way.  In this test box, we configured owamp test and it was working.  We then setup traceroute and regular “Ping Test”, these two tests failed.  I found out that the problem was the chosen interface “p1p1”, perfSonar complains about:

 

'bwping: Unable to connect to p1p1',

'bwtraceroute: Unable to connect to p1p1',

 

By changing the interface from “p1p1” to “default”, traceroute started to work, but ping still failed.  The failing “ping” test was found out to be “-s 1000” problem, by reducing the size to 995, it worked!  This problem is probably due to a departmental firewall (outside of our control).

 

The log file show ping result, but I could not see the result in the “Throughput/Latency Graphs”, I then disabled owamp and I still can not see result.  Shall I delete the old owamp results?

 

Thank you.
