My goal is to duplicate a Linux box (Debian) across two identical sets of hardware. I used the dd utility to clone the drive of Box A to the drive of Box B. When I pop the drive for Box B back into its machine, I boot the OS and the network isn't connected. ifconfig -a shows only an interface for eth3 and lo, not the eth0 I was expecting.
Could this be the Linux installation using hardware infomation from the Box A, which is wrong when cloned to Box B? (Like a MAC address?) What is the best method to fix it?
