BB connection to ethernet port of the host

Hi everybody

I need to connect the BB to the net without using a net adapter but
using the ethernet port on my host (with a Linux OS).

Questions:
Can I do it?
What kind of connection do I need between BB and my Linux host? Using
a
simple cable to connect one of the BB USB ports to my host USB port is
enough?
Do I need to do anything on my host (e.g. configuring it to work as a
router)?

Thank a lot in advance for any help.

Ciao,
Ska

Hi Ska,

You should be able to connect your BB to your Linux PC host using a normal
USB cable connected to the BB OTG port. Then you can setup a network
connection over USB between the PC and the BB.

You then need to configure your PC to bridge the two network cards (your
real network card and your USB pseudo network card). I currently can't
remember how to do this, but search the net - This is definitely possible...

The procedure should be the same as the one used for configuring your Linux
PC as a firewall/router - Except this connects two "normal" network cards...

Best regards - Good luck

Hi Søren

Thanks for your fast reply

"Then you can setup a network
connection over USB between the PC and the BB"
How can I do it? By using ifconfig command?

Thanks again,
Ska

Hi Ska,

Please take a look at:

I haven't tried it myself, but I think this is basically what you need...

Best regards - Good luck

Hi Soren,

Your response to Ska was timely for me too … I’ve been successfully using 2.6.29-rc8 kernel with my Slackware PC (12.1) using a USB to USB connection for NFS mount. (RFS is Angstrom ‘latest’ I pulled from site a few weeks ago). I’ve had issues, though, with accessing SD partition that has boot images yet. I can get to partition 1 via /media/card mount. In additon, I don’t see any kernel diagnostics relating to MMC detection at power up. I’ve been spending time studying how udev handles device enumeration to better understand what’s going on.

So I acquired 2.6.28, re-configured the kernel options for USB (gadget stuff etc) and can now see MMC detection diagnostics but can’t mount NFS … I’ll continue to check all the configuration options I changed for 2.6.28; any particular USB configuration changes/differences to look out for?

regards, Rich

Thanks!
I will print it and read it in front of a sandwich right now...

Hi Rich,

Not that I know of – That being said, I’m not that much into all the
different Linux revisions/builds, so I think I’m not the right one to
comment on this. With respect to Linux I’m mostly knowledgeable about the
great lines and not all the minor (though important) details :slight_smile: – In
general I’m more into the hardware and chips part :slight_smile:

I therefore think some of the others on this list might be better at
answering this...
