Hi!
I'm trying to set up a mesh network (OPEN mesh network) using the
instructions on https://github.com/cozybit/open80211s/wiki/HOWTO
I'm running a vanilla kernel, but as far as I know the support has
been in the kernel since '11 , so that shouldn't be the issue.
Any ideas on how I could fix this? I want to set it up so that I can
build stuff on top of it.
(Both machines are running hardware with the ath_9k driver which seems
to be the most supported driver for setting up meshes)
This is what I've tried so far:
The shorter version:
root@xyz:/home/yz# service network-manager stop
network-manager stop/waiting
root@xyz:/home/yz# iw --debug dev wlan0 interface add mp0 type mp
mesh_id abcdefgh
root@xyz:/home/yz# iw --debug dev mp0 set channel 2
root@xyz:/home/yz# ifconfig mp0 hw ether 94:a0:c0:b1:11:42
root@xyz:/home/yz# ifconfig mp0 192.168.3.82
root@xyz:/home/yz# iw --debug dev wlan0 interface add mp1 type mp
root@xyz:/home/yz# iw --debug dev mp1 set channel 2
root@xyz:/home/yz# ifconfig mp1 hw ether 94:a0:c0:b1:11:45
root@xyz:/home/yz# ifconfig mp1 192.168.3.84
root@xyz:/home/yz# iw --debug dev mp1 mesh join abcdefgh
root@xyz:/home/yz# iw dev mp0 station dump
root@xyz:/home/yz# iw --debug dev mp1 mesh join abcdefgh
command failed: Operation already in progress (-114)
root@xyz:/home/yz#
-- End of shorter version
At this time, I see "Not connected" If i try to query the interface's
status using link in the iw utility.
I've tried creating these scenarios :
Interface mp0 and mp1 on the SAME machine.
Interface mp0 and mp1 on Different machines.
But in both these situations, I'm not able to ping the IP addresses
from each other.
I have gone through the linux wireless page on iw a few times but that
doesn't seem to offer much help.
Any ideas why the node is not able to connect to the mesh ?
Thanks a lot!
PS - In case someone's interested, this is the longer version of the
same with debug enabled :
