I am working with a small Linux computer that has an Ethernet interface on it.
Typically it has the lo "Local Loopback" interface on it & the eth0 "Ethernet" interface on it that does all of its Ethernet handling.
However, when I have ran the ifconfig command on it, my computer only recognized the lo interface on it and can't find its eth0 interface.
My Ethernet interface is built into the computer, so I don't think its an issue of hardware failing.
Is their some Linux command to rerecognize or scan for the Ethernet interface and try to find it?
