I searched, but just cant seem to put all the pieces together.
I hope this is something very simple.
I apologize if this was already covered and I just wasn't able to
comprehend.
Given: Angstrom Demo already installed, 2.6.29r37 kernel, beagleboard
rev C3, and one USB mini A or B cable?
(i.e., only one cable connected to the beagleboard)
Is it possible to run ssh from the PC that is powering the
beagleboard?
If so, please point me in the right direction.
Yes.
Make sure you have the g_ether module loaded on the beagleboard, and
the cdc_ether module loaded on the host PC. If you have NetworkManager
v0.7 or better installed on the host PC, this whole thing gets a lot
easier: an Auto usb0 connection profile will appear in the "Edit
Connections" window. If you edit the DHCP setting to say "Shared with
other computers" or something like that, and then restart dhcpcd on
the beagleboard, you will get an IP.
Otherwise, if you don't have a recent enough version of
NetworkManager, you'll have to do basic NAT forwarding:

Ack. I forgot to finish. When your beagleboard gets its IP address,
run ifconfig on the beagleboard and figure out what IP it received.
You should be able to SSH right into the bb from the host PC (and the
host PC only, if I recall correctly) using that IP.
Thank you for the tips.
I installed the windows XP driver http://www.davehylands.com/linux/gumstix/usbnet/linux.inf
per the gumstix how to.
I loaded the g_ether and related modules from
http://www.angstrom-distribution.org/demo/beagleboard/modules-2.6.29-r37-beagleboard.tgz
(btw: this fixed my ipv6 struct mismatch)
The following is a dump of my current progress.
Please shove me in the right direction again.
Thank you and respectfully,

I was not able to run insmod, modinfo... on g_ether like you can with
other modules
So I supplied the entire pathname:
root@beagleboard:~# insmod /lib/modules/2.6.29-omap1/kernel/drivers/
usb/gadget/g_ether.ko
and got:

[ 127.490631] Kernel panic - not syncing: Fatal exception in

this also locked up my pc until I unpluged the USB cable
Quick update.
I can get a network up over the OTG usb connection using an iMac and
manually configuring the subnet.
I assume that would be true for a Linux box as well.
I have not tried DHCP.
So the problem may lie in the PC linux.inf / usb8023.sys driver pair
If anybody has any tips please let me know.
In the mean time I'll see if there is a newer usb8023.sys
