Sorry, I should have mentioned that - I'm booting off the on-board SD card. A while back the roach was set up to use NFS and it is possible that this roach still has some settings left over from that.
I've been trying to get the roach USB port to work as a regular USB port so I can control a valon 5009 frequency generator. I was missing some commands (lsusb) to I tried to download them from the roach using apt-get and this is what showed the network problem. I have no problem talking to the roach only trying to access the network from the command line once I've logged on via ssh. Given I'm messing with the system using NFS seems like a bad idea. If anyone has been talking to a valon from a roach board I'd love to hear what was done - I see some notes about talking to a valon on the casper list but it was not clear if this was done from the roach or (as we are currently doing) from a separate computer (and no details were given on the setup).
