perfSONAR User Q&A and Other Discussion

["Fedorka, Shayne" <>]

 

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).

 

flatirons-perf02-100g:~$ ping 192.174.57.10

 

Command 'ping' not found, but can be installed with:

 

sudo apt install iputils-ping    # version 3:20190709-3, or

sudo apt install inetutils-ping  # version 2:1.9.4-11ubuntu0.2
