need rma beagle bone eth0 not working

[jsjrstewart]

booted directly from beagle bone black, no ipv4 address obtained cable and router are fully functional
also booted from micro sd card same results
How do I obtain an rma

The Beagle Board folks handle all Beagle Bone RMA's directly. If you contact them at this link they will take care of you:

I don't know if this is @jsjrstewart's problem, but the Debian on the Rev C board I just received (12/11/2014) did not have eth0 enabled. I had to connect via the USB cable to get into the box in order to see what was wrong.

In the file /etc/network/interfaces, at line 9 of that file you'll see it's commented out. I.e.:

#iface eth0 inet dhcp

I have no idea why they would ship it this way after having gone to the trouble to set up the USB at 192.168.7.2 (as shown at the bottom of that file). To enable eth0 dhcp, simply delete the leading '#' character, write the file out, then do:

service networking restart
ifconfig

And you should see eth0 with an IPv4 (in my case) address.

Note to Adafruit: you may way to put another little piece of paper in with the BBB C telling people about this, or (better yet) get your upstream providers to ship the image with the interface enabled.

Thanks for the heads-up. We'll look into it.

Actually I'm not sure the BeagleBone Black's debian image uses the /etc/network/interfaces file for the ethernet network. I just flashed a fresh image and also saw it's commented out there, but when I plug in an ethernet cable it fires up the eth0 connection and shows the IP address, etc. with ifconfig. I have a feeling they're doing something fancier, like perhaps have a systemd service that starts up when ethernet is connected. You might ping folks on the BeagleBone Black support group to see if they have input on how they setup eth0 without it being explicitly configured in /etc/network/interfaces.

Ah, good old f'in systemd. It's like Firesign Theater rewrote UN*X so that "Everything you know is wrong!" (https://en.wikipedia.org/wiki/Everythin ... _Is_Wrong))

When I first got my Beaglebone I did a lot of searching to get ethernet working. The problem is that there are several old versions of Debian network setting tutorials floating around. It turns out it is dead easy with the latest Debian. In the GUI click the lower left->networking->WiCd

You set up ethernet and wireless dongles under preferences in the menu bar at the top.

"In the GUI ..." Aye, there's the rub. I'm Old School (at a UN*X prompt since 1980) and all I wanted/needed was a working SSH daemon available on a working Ethernet port so I could get a shell prompt.

The GUI runs on an X server clone. You can open a terminal and type all the flipin UNIX commands you like. :-) I am trying to say I did the UNIX commands and it was different every Debian release.

SSH I did ssh-keygen then added ~/.ssh/id_rsa.pub to PC's ~/.ssh/authorized_keys list.

I run XCygwin on my PC and tunnel into the BBB(Beaglebone Black) by typing in an xterm on my PC:
ssh -Y <BBB username>@<ip or name in hosts file>

If I type "pcmanfm" from SSH shell the file manger running on the BBB sends it's window to my PC.

I also made serial cable for the console.

I started using UNIX in the 80's, too. HP-UX, Sun-OS, IBM os etc. The company made i/f cards to connect different computer types together.
