perfSONAR User Q&A and Other Discussion

[Oleg Moiseichuk <>]

Hello, Chris.

Right you are!
A bit earlier my colleague proposed replacing "address localhost" with 
"address 127.0.0.1" which is the same.
I corrected /etc/perfsonar/toolkit/configdaemon.conf on all my nodes and 
run "systemctl restart perfsonar-configdaemon" on every one and that did 
the trick.

It seems that only one socket is opened: IPv4 or IPv6. During install 
the proper one was opened, as I changed some settings and they were 
saved correctly. But later, when I placed all the nodes where they were 
intended to be, all of them opened IPv6 socket.
This looks like a bug to me.
