Nach diverser Downtime und viel Prokrastination ein Update auf WordPress 3.0.1, Umzug auf dd19.de und dann auch gleich ein neuer Titel. Die K:ita ist inzwischen abgerissen, die Website irgendwo in den Backups verschollen und der Google Rank existiert nicht mehr, da war dd19.de einfach passender .

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.

Nach dem ich für ungefähr einem Monat Piratenfreifunk gestartet habe, um meinen Ergüssen auch Taten folgen zu lassen, haben wir inzwischen erste vorzeigbare Ergebnisse:

• Ein Repository auf github
• Eine vorzeigbare Demo
• und erste installierbare Firmwareversionen.

Kleine vorstellung soll am Di, den 25.8. 09 im Breipott in der Skalitzer Strasse (berlin) sein.

Update: warscheinlich um 20:00 Uhr

wie warscheinlich der rest der regierung ist auch der epetitionsserver, welcher bei der geringsten abweichung vom vorgegebenen weg laut “Hacker” schreit, wie jetzt ein kollege herausgefunden hat.

Stelt sich nur noch die frage, wie ich damit umgehen soll, einen potentiell schwerkriminellen im umfeld zu haben.

Ausserdem war das verwendete hackertool ein firefox, vielleicht sollte ich  nur noch mit Safari surfen, um mich nicht verdächtig zu machen.

Fragen über fragen …

Recent experiments mit l2gvpn resulted in an olsr-mesh with over 1000 nodes:

Die Folien des Vortrages, den Daniel und ich am Mittwoch über IPv6 und siit gehalten haben, sind nun online: http://download.berlin.freifunk.net/pdf/vortrag/6mesh/

Ufo vom Rundfreifunk hat mich auf dem 25c3 interviewed, das mp3 gibs hier.

The 25th chaos communication congress is coming and the wireless community will be there. This time, we got a nice cosy space in the famous hackcenter, in the Wireless corner.

We will be right next to other interesting project like:

• GSM Hackers
• Console Hacking
• The Bricophone people

More on the floorplan.

We are going to build a ipv6 only mesh using siit to transport translated ipv4 traffic.

So, preparation are happening all over, even if you can see them only if you have a very close look:

Jow is fixing tickets and enhancing the openwrt luci framework to make sure we have a good start into the experiment.

Meanwhile, Daniel is working hard on our BGP routers to make sure we get a direct routing for the freifunk PI network into the 25c3. As you can see, our RIPE entry has been updated to enable routing to and from AS249, the congress network.

Felix has ported the siit kernel module to kernel 2.6 and commited.

Lehox and friends are working hard on n2n to get at least the worst bugs fixed, as we are going to use it as the backup vpn to our other BGP routers.

There is still a lot to do, but it looks like we are on a good way.

nbd did a port for linux kernel 2.6, which needs to be tested:

kamikaze package dir: http://nbd.name/siit.tar.gz

joti did som make stuff for “normal” linux: https://norwegen.soziologiker.org/hg/siit

please test and give feedback.

Update: first tests succeeded.

Yesterday, i thought, what a pitty, this blog has no AAAA record and no ipv6 address. As it is hosted on a FreeBSD jail and the host is neither patched for ipv6 jails nor has an ipv6 connection, i had to find an other solution.

I have a VM with a 6to4 tunnel running lighttpd, so i let the AAAA record for this blog point on that machine, enabled the proxy module and added following config to the proxy configuration:

$HTTP["host"] == "blogs.k-ita.de" {
  proxy.server  = ( "" => ( ( "host" => "80.237.196.30" ) ) )
}

It’s not the cleanest solution, but it works for me[TM].
