Last weekend the beaglebone stopped talking on the Internet.  I spent a 
day trying to figure out the problem and finally decided to reimage to 
Micro SD memory card.  I used
Angstrom-Cloud9-IDE-GNOME-eglibc-ipk-v2012.12-beaglebone-2013.06.17.img.xz

This is the modifications I made to get the system going again.
