I had a Dell machine and the motherboard went belly up. So, I took my

it, or rather me, seem to be a little bit confused about the on board
ethernet.


Doing an ifconfig -a shows:

# ifconfig -a
eth1      Link encap:Ethernet  HWaddr 00:1D:0F:C0:01:BC
          inet addr:192.65.171.33  Bcast:192.65.171.63

eth2      Link encap:Ethernet  HWaddr 00:1A:4D:5E:F2:75


I am a little confused about udev remapping eth0 to eth1 and eth1 to
eth2. Why isn't there an eth0 ?


Look in /etc/sysconfig/network-scripts for the ifcfg-eth? files. The HWADDR = entries in the appropriate files need to match the real MAC address from your new motherboard - that ifconfig displays. If they don't match, the interface won't come up. You probably have some invalid copies now and some new copies.

So, how do I get Linux to recognize the new motherboard's ethernet card
as eth0 instead of eth2 ?

Edit/rename the ifcfg-eth? files to make the filename, DEVICE= and HWADDR= settings match what you want.
