perfSONAR User Q&A and Other Discussion

["Fedorka, Shayne" <>]

Here’s an update on my 5.0.5 issues:

 

I resolved the ping and rtt issue by simply reinstalling the iputils-ping package. This is does not appear to be an issue on a clean install of Ubuntu 20.04 and perfSONAR 5.0.5 (I only noticed it on servers where I upgraded from 5.0.4).

 

A new issue – I’m unable to save changes on the host configuration web interface. On the clean 5.0.5 install I’m presented with the following error: “Error - Problem saving configuration: Problem saving NTP configuration.” On an upgraded 5.0.4 to 5.0.5 install I don’t get an error, the page just hangs.

I recently updated my Ubuntu 20.04 server to perfSONAR 5.0.5 and I’m still seeing the same issues with logstash authentication as in 5.0.4.

 

In addition to that, rtt tests are failing now. It’s acting as if I don’t have ping installed (even though it is).
