Hmm, could you please post a full debug log (from --log-file),

Running the exact same command as posted with --log-file appended and scrolling a bit through the file, I found the following lines interesting:

It seems like the -6 argument is not passed to the irtt command. See the full log file attached:
rrul-2021-10-01T085102.606290.log

output of this command (with both address families defined in your /etc/hosts):

[(10, 1, 6, '', ('a::601', 0, 0, 0)), (2, 1, 6, '', ('10.0.6.1', 0))]

Do those commands work for you outside of flent from your mn.h1 to mn.h2?

Yes, with no problems at all, getting the respective same output as posted by you.

I also wonder what happens if you don't use --local-bind.

irtt connection no longer fails, as there's no mismatch in address families. However, as long as mn.h2 has an IPv4 defined, it uses IPv4 to connect, disregarding the -6 param
