G'day,

I've been working away on automation of the tests. Pretty close to having much nicer tests with a lot more details. I've also got the risc-v device working.

However, I've run into something funny with flent. Flent is not happy with fping or ping.

das@3rd:~/Downloads/cake/cmd/run_qdiscs_tests$ /usr/bin/sudo /usr/sbin/ip netns exec network101 /usr/bin/flent rrul --output /tmp/qdisc/2023-10-13T15:53:21/pi4/noqueue/flent/test/15_flent/flent_pi4_noqueue.png --data-dir /tmp/qdisc/2023-10-13T15:53:21/pi4/noqueue/flent/test/15_flent/ --format summary --plot all_scaled --title-extra 2023-10-13T15:53:21_pi4_noqueue --note 2023-10-13T15:53:21_pi4_noqueue --extended-metadata --host 172.17.51.10 --length 60 --ipv4 --socket-stats

I did install via "apt install fping"

Any thoughts please?

Kind regards,

The announcement was end of October, but I think I could pre-order right now if I was feeling an urge. You are right though, announced != available or delivered.

P.S.: I have a pi400 in use as "desktop" for my oldest kid, this is close to be actually generally usable, I would guess that changing a potential p500 from the pi400's 4GB to 8 GB together with the other imprivements the 5 brings might push it over the threshold into the truly useful category. Which probably means that either a potential pi500 will come late and probably with only 4 GB, but let's see how this works out now that the supply situation is less problematic.
And I understand that there are other capable ARM based SoCs for homerouter/desktop duty, I just happen ot have a soft spot for the raspberry project ;)
