Sharing Laptop Internet Connection with BeagleBoard
I've been trying to figure out how to share my laptop's wireless connection with my BeagleBoard (which is connected to my laptop with a crossover Ethernet cable). I'd still like to figure out how to set this up from the command line and making actual system changes, but haven't been successful with various guides I've found via Google so far. I did find this one easy solution that uses the Network Manager, though.

Setup Steps
 * Ubuntu 10.04 64-bit with wireless connection
 * BeagleBoard-xM
 * Ethernet crossover cable connected between BeagleBoard and laptop
 * 1) In Ubuntu, go to System -> Preferences -> Network Connections
 * 2) On the 'Wired' tab, select 'Auto eth0' and click 'Edit' (Note: name may be other than 'eth0'.  If nothing exists in this list, then you've made modifications to your system and network manager is not allowed to manage your Ethernet connection.)
 * 3) Click the 'IPv4 Settings' tab and change 'Method' to 'Shared to other computers'
 * 4) Click apply
 * 5) Restart Ubuntu
 * 6) Connect the BeagleBoard to the laptop with the crossover Ethernet cable
 * 7) Boot the BeagleBoard - if Ubuntu was already running and the Ethernet cable was already plugged in, the BeagleBoard should automatically get assigned an IP address and you should be able to access the Internet on the BeagleBoard via the laptop's wireless connection
