Hi Nevio,

Hi,
here Nevio, from Italy. I'm new in the forum.
I'm playing with a BeagleBone Black C with debian 7.5 2014-07-06 version.
The BBB is connected to the local network with internet access, and I run
it with ssh.
I have connected also a usb internet-key (Huawei E3131) that work out of
the box. This internet key is different from the others because it is seen
as an ethernet device, not usb device.
Sorry if this is not the focus of your question, but can you tell how you
make this modem work like an ethernet device? Plug'n play or did you do
some kind of configuration?
I've recently have some problems on make this modem work in ofono, but if
the modem can work it would be nice.
I am having trouble with configuring which internet connection the system
has to use.
In particular I would like the BBB use the internet connection via LAN if
the internet via LAN is up, else the other connection (via usb internet
key).
I have configured the two eth connections with different priorities
(/etc/network/interfaces), however if the LAN has no internet connection
the system don't use the usb-key.
I post my config file.
eth0 = wired connection, gateway 192.168.0.1
eth1 = via usb internet key, gateway 192.168.1.1
I believe Debian default network connection manager is Wicd, I never used.
I'm currently using Connman to manage connections and default route. You
can check some documentation here:
