• the errors calling node 14 was due to an error on the server there, a restart now fixed it, but needs more investigation of what caused this at first place. (restarted in debug mode to get more info)
• expected it was happening due to an iperf client calling iperf server on the same node (since node 14 is runs a server) but it is not, verified after a restart calling the local server and it works
• the zeros calling node 11 looks like it was temporary, or failed run of the iperf since it didn't populate any fields at all even the ip. but it returns a valid values now
