how to disable wlan and wwan at startup

2010-12-10 Thread pritam.ghang...@gmail.com 
Hi

I want only wired networking from NetworkManager.

Can I disable wlan and wwan with some configuratoion option in
nm-system-settings.conf. So that it doesn't even load the corresponding
code/modules.
runtime memory consumption is important to me.

I tried looking for help on configuration but couldn't find much.

Even if it doesnt reduce memory footprint I dont want network manager to
look for
modems and wlan devices or load any configuration of that kind.

NM isn't working on embedded linux, ignoring interface.

Hi

I am trying to get network manager working on a embedded Linux platform.
The setup has a custom SOC with network controller on board.
Vendor has provided us BSP that contains Linux kernel with network driver
built into it.

Kernel version is 2.6.22.19 and its running busy box.

When I try to run NetworkManager it gives out following output:

$ ./NetworkManager --no-daemon
--config=/etc/NetworkManager/nm-system-settings.conf

As we can see in log it has started but ignored both the network interfaces

I found a thread with the same issue(
http://mail.gnome.org/archives/networkmanager-list/2010-July/msg00015.html),
but it doesn't have any pointers to solution.

Here is my output of ls -la /sys/class/net
