Hi all, particularly those who attended the workshop on 31st March and 1st April, and last saturday Rony, Jtd resumed the work.

Last saturday we successfully managed to get the mesh working. Actually the mesh works out of the box like a charm. We only used several of our legacy skills and actually wasted lot of time. But at the end every moment spent was useful. We now know exactly what to communicate to others who wish to setup such a mesh (mess ;-) successfully.
The dhcp on wireless was not working as of Saturday, but today afternoon I tried based on a reply from the olsr-users mailing list. Again it worked out of the box.
What I did:
installed a package called 'freifunk-dnsmasq', restarted it. Now we see an additional parameter on the web interface called OLSR-DHCP: This is where we give the DHCP share of the mesh network (not the lan network). thats it.
Now we have a working mesh in the campus. I will write documentation here: http://fci.wikia.com/wiki/WirelessMesh. Please add to everything I missed out. I will also upload few screen shots so that new teams setting it up will find it useful.
Next step:
Prepare a server (Rony contributed a server) and dump useful resources there for community use. Next time, gluggers can walk into our campus and sit in our lounge with a laptop and takeaway what the server has. If we get a list of goodies that the community needs we will begin archiving them. So send such a request to glab@hbcse.tifr.res.in. we will download them during the night time and leave it one the server.
Great news. Please link up these how-to-do-it pages in the wsfii wiki also.
The resources idea is brilliant and a great boon. Please see how soon we can make this work. Actually, I think from what I heard in Dharamsala, it should be possible for us to 'mesh' into the system remotely wherever we are located, provided we run OLSR locally and tune it to the same mesh. In that case, downloading the resources will be just a hop or or two away. Is this understanding correct?

Secondly, without the dnsmasq package, can we get the native udhcpd to work with the OLSR interface? I think we can.. What's the OLSR interface that shows up with ifconfig? It is possible, I think, to manually configure the DHCP server to listen on the OLSR interface.
The problem, I think, wasn't with the missing package, but with the fact that we had DHCP running on the WLAN interface instead of the OLSR interface. The native DHCP should work perfectly fine if I'm right... unless dnsmasq has some features I don't know about..
Is it possible to 'test-bed' this on a non-wireless, perhaps a standalone, device? Can we create ghost nodes somehow? Anyhow, it hardly matters, since the actual test-bed will be available at HBCSE for trials.

More or less. except that the range is limited to about 100 mtr outdoors, so you require an ap every 100 mtrs to expand the mesh, and the latency keeps going up as u move away from the internet gateway point. However if there are a number of aps with an internet connection the situation improves a great deal. Also it is possible to extend the distance between two nodes using directional antennas, but they wont be able to provide connectivity to others around them without one more ap or a splitter amplifier omni antenna.
