I have a fresh install of Fedora 17 installed, 64 bit. Everything works flawlessly, It connects to the internet automatically when I plug in the internet cable.
So I'm kind of confused when I issue this command:
el@defiant ~ $ ifconfig eth0
And I get the error:
eth0: error fetching interface information: Device not found
Device not found? Here is ifconfig:
ifconfig
I get this:
em1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

So, it appears that someone has changed the old eth0
to em1
since earlier versions of Fedora (Fedora 8 is the last I know which used eth0
). If I do the command: ifconfig em1
then I get something similar to the old ifconfig eth0
. But why the name change?
My question is why was eth0
changed to em1
and what the heck does em
from em1
mean?
