question about open11s installation
From: 임영빈 <hidden>

Hi
I installed open11s through wireless-testing and also through compat-wireless.
I used b43 chipset wlan cards(Asus WL-138G V2 PCI card) which are
known to work with open11s.
I could make the mesh interface, and see neighbor nodes by 'iw dev
mesh station dump'.
But its output is slightly different from open11s manual like this.
root@ybim-desktop:~# iw dev mesh station dump
Station 00:1b:fc:3e:52:44 (on mesh)
inactive time: -66040 ms
rx bytes: 0
tx bytes: 0
And what is serious is that when I execute the command 'iw dev mesh mpath dump'.
I lose my ssh connection, and the system gets strange.
The symptom is the same in both cases, wireless-testing and compat-wireless.
I got below messages through dmesg when I used wireless-testing.
Actually, I used following commands to create the interface.
export MESH_ID=1023
iw dev wlan2 interface add mesh type mp mesh_id $MESH_ID
ifconfig mesh down
iwconfig mesh mode ad-hoc essid open11s channel 3
ifconfig mesh up
ifconfig mesh 192.168.4.2
But, someone said to me that to use the command 'iwconfig mesh mode
ad-hoc essid open11s channel 3' is not
good way because it can make a problem with mesh interface mode.
So I changed the commands like this
export MESH_ID=1023
iw dev wlan2 interface add mesh type mp mesh_id $MESH_ID
iwconfig mesh channel 3
ifconfig mesh 192.168.4.2
Then I couldn't even make any connection
between nodes, that is, I could not find any node when I typed 'iw dev
mesh station dump'
I think I correctly installed following open11s manual, and the hardware is ok.
But I cannot figure out the reason. Any ideas?
Thank you.
