Hmm, this looks like a bug in netperf - I guess it fails to pass the address family when resolving the local-bind hostname. I suppose we could resolve it in Flent and pass down the IP address instead to work around this...

As the command runs fine without
--local-bind
, I suppose this is not of high importance, nonetheless, I wanted to report this. Also, the irtt for latency measurement runs fine in this test, it's only the netperf for IPv4 that fails.Full verbose output: verbose_rrul46compete.txt
