[Flent-users] weir error message after update of macosx and flent

[Sebastian Moeller]

Hi Toke,


I made the mistake of updating both my os (from macos 10.12.6 to 10.13.3) and flent (to 1.2 I believe) at the same time. Now when I try to actually run a test I get the following results:

Started Flent 1.2.0-git-94b4267 using Python 3.6.4.

During handling of the above exception, another exception occurred:

Opening run-flent --gui however works as expected. I guess I made a silly mistake, but since I get these errors with pyhton 2.7 as well as the shown python 3.6 I just wanted to ask whether this "rings a bell" or whether I need to look deeper into my setup.



Things I did test already:
1) netperf: I used Rich Brown's betterspeedtest.sh wrapper to test whether netperf is operational (it is) Also:
bash-3.2$ netperf -4 -H netperf-eu.bufferbloat.net -t TCP_STREAM -l 10 -v 0 -P 0 -D 2
Interim result:    7.66 10^6bits/s over 2.053 seconds ending at 1518903857.219
Interim result:    8.81 10^6bits/s over 2.023 seconds ending at 1518903859.242

2) fping:
bash-3.2$ sudo fping -D -n -c 2 127.0.0.1 -i 5

I think that’s the right thing to do, and was thinking the same last night. :) It would seem to best reflect reality. One user thought that ToS wasn’t implemented in IRTT because there was no —tos flag, so that’s what people expect to find. This way they’d find it, but the doc would also mention that DSCP is mainly what’s used on the modern Internet.

Now, it also might be that the text values for ToS could be different than those for DSCP, and there could be two different tables. I’m not sure yet, but I’ll consider that after reading up on it more…
