On server side: `sudo netserver -6 -L fe80::200:aff:fe00:e02%h2-eth0 -p 12865 -d` to start the netserver, then `sudo irtt server` for the irtt server On client side: `sudo flent rrul -6 -p all_scaled --local-bind=fe80::200:aff:fe00:601%h1-eth0 -l 60 -H fe80::200:aff:fe00:e02 -t ipv6 -o ipv6_dscp.pdf -v` fails to achieve the UDP RTT measurement, but completes the TCP and ICMP6 part (full verbose output below). Running the same command with IPv4 addresses of the hosts (netserver enabled respectively): `sudo flent rrul -p all_scaled --local-bind=10.0.6.1 -l 60 -H 10.0.14.2 -t ipv4 -o ipv4_dscp.pdf -v` works just fine.

I'm running the flent tests in a mininet with IPv6 enabled (ping is working).
On server side:
sudo netserver -6 -L fe80::200:aff:fe00:e02%h2-eth0 -p 12865 -d
to start the netserver, then
sudo irtt server
for the irtt server

On client side:
sudo flent rrul -6 -p all_scaled --local-bind=fe80::200:aff:fe00:601%h1-eth0 -l 60 -H fe80::200:aff:fe00:e02 -t ipv6 -o ipv6_dscp.pdf -v
fails to achieve the UDP RTT measurement, but completes the TCP and ICMP6 part (full verbose output below).

Running the same command with IPv4 addresses of the hosts (netserver enabled respectively):
sudo flent rrul -p all_scaled --local-bind=10.0.6.1 -l 60 -H 10.0.14.2 -t ipv4 -o ipv4_dscp.pdf -v
works just fine.

The difference in output comes in these lines:

Ping (ms) UDP EF: Adding child IrttRunner
which: /usr/local/sbin/irtt is not an executable file
which: /usr/local/bin/irtt is not an executable file
which: /usr/sbin/irtt is not an executable file
which: Found irtt executable at /usr/bin/irtt
UDP RTT test: Cannot use irtt runner (Irtt connection check failed: Error: address fe80::200:aff:fe00:601%h1-eth0:0: too many colons in address
). Using netperf UDP_RR

which comes from flent passing the IPv6 address not in the correct format to irtt - irtt requires the IPv6 passed in [a::b] brackets, to distinguish it from the port (if I read it correctly, reference to the irtt page
