Set DNS nameserver?
The below more detailed answer is partly to help me remember next time I forget.
The DNS (nameserver) is called out in /etc/resolv.conf -- Therefore find/google the nameserver for your internet provider, and edit /etc/resolv.conf to match:
nameserver 64.169.140.6
or whatever your nameserver is.
While I'm at it, if you use ubuntu, "sudo echo 1 > /proc/sys/net/ipv4/ip_forward" doesn't seem to work due to permission issues. Instead do a "sudo -i" and then do the echo 1 command from the resulting root prompt.
Oh, I also notice that I need to turn off the firewall on the PC (firestarter) for the usb networking to work. I am not smart enough yet to get it to work with the firewall running.
