Two ethernet cards

[Jason Rennie <jrennie@alum.mit.edu>]

Hello,

I have a laptop with docking station.  The laptop has a PCMCIA
wireless card; the docking station has its own ethernet port/card.

When I boot up w/o the docking station, the wireless card is
recognized as eth0 and the network comes up properly.

When I boot up with the docking station, the docking station ethernet
gets eth0, PCMCIA gets eth1 and Debian tries to bring up the network
via eth0.  Unless I connect with a ethernet cord, networking fails.

Following suggestions from the recent "DHCP Question" thread, I added the
hardware address to the eth0 section of my /etc/network/interfaces file:

auto eth0
iface eth0 inet dhcp
        hwaddress ether 00:50:8B:46:28:6F

Now, when the laptop is docked, PCMCIA comes up as eth0, but
networking doesn't work.  During boot, dhclient runs and fails
(DHCPDISCOVER, DHCPDISCOVER, ..., No DHCPOFFERS received).  I tried
running dhclient after the machine was fully booted... it again fails.
PCMCIA card flashes its LED to indicate that it has been initialized,
but it is not connected to a network.

I use a DSL wireless router for networking.

Anyone have any suggestions?

Many thanks,

Jason
