Hi,
you know we already have B.A.T.M.A.N in OpenEmbedded but now I gave good
old OLSRD a try too.
I added a recipe for the latest release 0.5.5 and tested it on the
device. It is working nicely along with the ar6000 being in ad-hoc mode
(the preferred mode for mesh networks ;) ). No luck with 0.5.3 though -
it crashes when I want to view the page generated by the httpinfo plugin.
I wanted to do some NATting between the wifi interface and the usbnet
connection (effectively making my desktop computer an internet gateway
for the Berlin Freifunk community).
However this was impossible since OpenMoko does not provide the iptables
package (you can get the kernel modules but not the userspace
application). You can build it on your own and then everything is fine
though.
There are also some minor issues with the wifi driver. I reported
this[0] a while ago already.
I am already happy but I would be so even more if:
- olsrd version preference could be set to 0.5.5
- iptables could be installed directly via opkg
The FreeRunner as a wifi mesh-node is a nice use case for the time after
being a mobile phone. It would be one of the very few nodes that have a
screen attached. :)
I would like to offer screen shots but there is nothing spectacular to
see on them. But perhaps you like some console output instead:

(A fixed BSSID of '02:CA:FF:EE:BA:BE' is what we use in Berlin to
overcome some problems with ad-hoc mode specification.)

Actually I could find something that may show I am really using this on
the Neo. I attached is httpinfo plugin generated webpage showing my
configuration. There are few devices where eth0 is a wifi card. :D
If you are interested I also attached by olsrd.conf. You need to have
olsrd-plugin-httpinfo, olsrd-plugin-nameservice (didn't work as
expected) and olsrd-plugin-dyngw installed besides the daemon.
