USB networking: tethering

We want connect a computer through USB with our BQ, run TCP/IP over the link, perhaps even through this to Internet, like this:

netbook ---(USB)---> BQ ---(data mobile) ---> Internet

For networking the bq supports tethering via an USB device (run the following in the terminal app):

$ android-gadget-service enable rndis

I do this after every boot from within the terminal app with a small script ~/

android-gadget-service enable rndis

The launch of the script is bound to a special key to make this easy.

This will switch the USB port from MTP to tethering and create a 'rndis0' network device whith the IP addr; The Ubuntu offers to the connected computer an IP via DHCP (somehow it takes sometime).

After this SSH is fine too as:

Welcome to Ubuntu Utopic Unicorn (development branch) (GNU/Linux 3.4.67 armv7l) >
$ netstat -rn
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface UG 0 0 0 wlan0 U 0 0 0 rndis0 UH 0 0 0 ccmni0 U 0 0 0 wlan0

How can I set it as default to rndis enabled?

Oliver Grawert:
you cant, it is hardcoded on boot to always have working mtp (until
here is a UI option to turn it on or off, we want regular users to
lways be able to exchange files), but you can override it in a user
pstart job that runs at a later point ...
Create /home/phablet/.config/upstart/rndis.conf with the following
--------------- snip ------------------
start on started indicator-network
android-gadget-service enable rndis
end script
--------------- snap ----------------
When the interface rndis0 is enabled, somehow HTTPS access to
the Ubuntu's app store is no longer possible; investigationg ...
