[linux-help] Re: Two NICs

[Jeff Vian <jvian10@xxxxxxxx>]

        The assignment of eth0 and eth1 is done during boot. It has to do with
the order in which devices are seen/configured.
        Since you had to switch the cables between cards to get the original
internet connection to work, it seems the new card you added was
assigned as eth0 and the original card became eth1.  The configuration
for eth0 stayed the same, just moved to a different card.

        Probably the PnP features, and sometimes that is flakey. However, It is
not mandatory that you have eth0 or eth1 assigned for a specific
function.  Since the system decided to swap them for you it is easiest
to live with it (Unless someone knows of a way under Linux to specify an
assignment that will remain static forever on PnP cards)

I use netconf after the hardware install to do the network configuration
so i can see the current assignemts/config and change it as I see fit.
