perfSONAR User Q&A and Other Discussion

["Curtis, Bruce" <>]

We have two perfsonar boxes and after the automatic upgrade to 4.0 some 
graphs stopped updating.

It looks like the common variable for the graphs that do not update is that 
perfsonar lists the IPv6 address under the host name.

I verified that I can run the throughput tests manually over IPv6 with the 
pscheduler command.

I do see lots of these error messages but haven’t verified that they are 
related to the problem.

Apr 23 04:12:41 perfsonar2 bwctld[28704]: FILE=sapi.c, LINE=391, 
BWLControlAccept(): Unable to read ClientGreeting message

  These are our two hosts that exhibit the problem.

https://perfsonar2.ndsu.nodak.edu

https:perfsonar.ndsu.nodak.edu

 Deleting the tests and adding them back with IPv4 set does not seem to 
result in working graphs either.


I also noticed the same problem on ps-border1-pt.lbl.gov to sites 
nersc-pt1-v6.es.net and bost-pt1-v6.es.net  and sent email to the admin there 
and received a reply that they will add it to their list of issues to look 
into.
