[gentoo-user] Q: How is that terminus technicus for...

[meino.cramer]

Hi,

I connected a Arietta.G25 via Ethernet over USB (using a simple USB
cable and hardware USB->Ethernet Adaptor to my Gentoo PC. I can ssh
on that little tiny board. Now I want to access the internat from
within the Arietta.  Therefore all requests need to be transfered from
the Arietta board to my PC, which then plays the role of an ISP to
the Arietta board and itself places the requests to the internet
instead of the Arietta board itself.

But this is a too longish explanation to be put into a google request.

Is there any name for that...so I am able to find the tutorials/howtos
myself?

Sorry...I am no native english speaker...

Best regards,
Meino

PS: What USB->Ethernet adaptor could one recommend...the Arietta is
USB-powered...?

If I understood this correctly this should do what you want:

- on the board set the default route to the PC

- on the PC set up "packet forwarding"

That's the best explanation I can give you without writing a full-blown
tutorial, but searching for that should get you going. :)

Sorry, I don't even know what Arietta may be.  You need to be able to forward 
packets from Arietta via your PC and 'masquerade' their address.  If the 
connection was via ethernet, then something like this would work:

echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -F
iptables -t nat -A POSTROUTING -j MASQUERADE

However, I am not sure if something special is needed for a USB to PC 
connection, it depends what the USB connection shows up as.  I hope this gets 
you on the right path.
