learned on the 26c3

Hi,
26c3 is over and we had quite some experiments going on. Not everything went good, but we learned a lot:

  • babel did not survive the hack-center.
  • ahcp did survive.
  • measurement needs to be improved

That does not sound much, but i think it’s valuable information as we can now concentrate on some things and forget the other.

Openimp did not run good, it had a memory leak we got not fixed during 26c3, so the router kept rebooting after a few minutes.
Babel also hat real trouble, it ate up a lot of cpu and memory, it felt like olsr 3 years ago.
A few harddrives did not survive the heat of colo, so a part of the topology data are maybe lost.
Firmware building and development did work quite good, but could be better, that was mainly my verpeilung, there is room for improvement.

I will continiue the tests in my local mesh neighbourhood without babel and without ipv4 based olsr, so expect more firmware builds soon.

wl0?

Filed under: freifunk, hardware, network — Tags: , , , — alx @ 4:43

While doing the last setup for the ipv4 through ipv6 mesh experiment, i set up an asus WL50g deluxe, one of the better router built.

Everything was going fine, except the fact i was too stupid to configure wl0 with the webinterface.

Even on the commandline, i was unable to find it, so in opened the case and saw it:

Burned Wireless chip

wl0 died

openwrt full build

Filed under: freifunk, miscellaneous, software — Tags: , — alx @ 12:53

Nbd told me, to build an full openwrt with all packages, ignoring the failing packages, add a IGNORE_ERRORS=m to the make call.

This will let continiue the build, even if a single packed marked with “m” failed to build.
