I am using a Panda Board which is running a build of Angstrom.

The Panda Board has an in build Ethernet port and this is working fine, getting a DHCP address successfully.

I am going to be housing it in a larger container than the one supplied, which won't give me access to the internal port, so I am trying to use a USB Network Adapter.

Angstrom correctly identifies the adapter but it never gets a DHCP address. I've tried connecting both and just the USB one, but only the internal one will ever get an address.

Can someone help me? I'm new to linux!

Have you added your USB ethernet device to /etc/network/interfaces? I think you need to do that. (A similar entry like the one for eth0 -- you can find out which device it is via ifconfig -a. It should be listed there if it is recognized properly.)

Note that you can also do Networking using USB, that is, without an ethernet adapter but with some fiddling with host (your Workstation) and slave (the Angstrom device).

Apart from that, ifconfig -a output and your /etc/network/interfaces would probably be helpful to corner the problem.

Hi, thanks for that, but it didn't work still. Could you see the additional info above and see if I added the USB devices correctly? I orginally added the additional eth1,2,3. Does the usb ones need the Auto prefix too? Thanks! – neildeadman Jan 5 '12 at 8:47
I'm not sure in which way the USB adapter appears in your system; assuming it's usb0, you could try ifup usb0 -- if this works, auto usb0 should solve your problem. But I'm unsure about this, I suspected the USB device should end up as an eth* device (check dmesg) in which case your configuration should already work. – sr_ Jan 5 '12 at 9:13
still not working! :( any other ideas? – neildeadman Jan 5 '12 at 10:29
Try dhclient -v {usb interface name} and see if the verbose output gives you any clues. Have you confirmed the usb interface works OK when addresses are set manually? – ultrasawblade Jan 5 '12 at 12:22

If you bind the MAC address of the USB ethernet device in the DHCP server it should work.

How would I do that? – neildeadman Jan 6 '12 at 8:25
