I have a desktop computer running Debian testing (squeeze), kernel
2.6.30, with KDE 4.2.4. Previously it had been connected by ethernet to a
similar machine using an interface eth0. Now I want to connect it to my
new DSL service.
I changed /etc/network/interfaces to contain:
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
# The loopback interface
auto lo
iface lo inet loopback
# for DSL
iface eth1 inet dhcp
and rebooted the machine. Then I have
offnode2:/home/cgm# ifconfig -a

The old eth0 interface is there, not the new eth1. I suspect udev is
interfering somehow.
ifup eth1 has no visible effect. ifup eth0 reports:
Ignoring unknown interface eth0=eth0.
I can find discussions of how to change the name of an existing interface
with udev, but nothing about removing one interface and adding another.
Any suggestions welcome. Let me know if other information would be
useful.
Yes, udev controls the interface name, but it's based on MAC
address, not IP address. So, do you have two ethernet ports on your
computer, and plan to use both at the same time?
