[WMN] Trying to set up a mesh network

[Cristian Nasuti]

Hi Joana!

I use Ubuntu with the kernel 2.6.32-rc5.
I followed the instructions to recompile the kernel in Ubuntu (
http://o11s.org/trac/wiki/Ubuntu) (read and follow all)
I use atheros wlan card, so ath5k is driver for my card; you must use the
driever for yours.

After this procedure you have 2 package with your compiled kernel. If your
machine have the same wlan card, you can use directly this 2 package in all
without recompiling on each machine.

Then I get the last wersion of iw:

sudo apt-get install build-essential libnl-dev
wget http://wireless.kernel.org/download/iw/iw-0.9.17.tar.bz2
tar -xf iw-0.9.17.tar.bz2
cd iw-0.9.17
./configure
make
sudo make install

Make this in all your machine and then you can configure the mesh network.


To create a mesh, I follow this instruction (note: I work logged as root):

killall NetworkManager
modprobe -r ath5k
modprobe ath5k
iwconfig

in the outup I see that the interface of my PC is wlan2, so I put down the
interface and delete it:

ifconfig wlan2 down
iw dev wlan2 del

Now I find the physical:

dmesg | grep ath5k

I have seen in the output message like this:
ath5k phy0: Atheros AR5212 chip found ... etc.

so I make a mesh interface on phy0:

iw phy phy0 interface add Mesh_Point_1 type mp mesh_id MY_MESH
ifconfig Mesh_Point_1 up
ifconfig Mesh_Point_1 10.0.0.1

Mesh_Point_1 is the name of the interface, MY_MESH is the name of the mesh
network.
Make this for all your node, whit the same mesh id "MY_MESH" and ip in the
same range.
After this try to ping:

ping -c 4 -I Mesh_Point_1 10.0.0.2
ping -c 4 -I Mesh_Point_1 10.0.0.3
...
(this instruction ping the 10.0.0.2 from the interface Mesh_Point_1)

And finally check the mesh link:

iw dev Mesh_Point_1 station dump
arp
iw dev Mesh_Point_1 mpath dump

If is all ok you ave an output like the one in HOWTO

I hope everything work,
ciao!
