@Pete I think you need to start netserver on the client fi= rst (in your case, you are running flent on the server): "ip netns exe= c client netserver"

Wow, I see flent=E2=80=99s combination plots are handy though.

Stuff to sort in irtt also. Merely setting the source IP of an outgoing pac= ket doubles allocated heap when it calls into x/net code. Super.

Ok, here=E2=80=99s a quick veth try but I gotta get to sleep so I=E2=80=99m= not investigating much =E2=80=99til later. I wonder if 4.9.0-4 is enough:<= br>
