Ok, there is no configuration for your device. :)

Sure. The loopback interface is initiated "manually" and all network devices are started via "ifconfig $DEVICE up ; pump -i $DEVICE".

Ok.

How do you bring up your network? :) Seems like you are using a DHCP based setup.

If you want to do it automatically start grml-network and configure it according to your needs. Or manually configure /etc/network/interfaces, take a look at /etc/network/interfaces.examples for some configuration examples.

If you want to use dhcp with the same setup as from live-cd mode make sure that CONFIG_DHCP='yes' is set in /etc/grml/autoconfig and the binary "pump" is available.

hmmm… that seems to have something to do with my messing with my DHCP client software.

Currently I manually start it up with:

dhclient

I took a look at how my Debian Sarge does. Would the following 2 lines good enough for eth0, without relying on pump?

# The primary network interface
auto eth0
iface eth0 inet dhcp

You can invoke manually whatever you like (dhclient is available by default on grml as well). But pump is used inside grml-autoconfig because it's faster than dhclient.

The Debian way of life is to configure /etc/network/interfaces like:

auto eth0
iface eth0 inet dhcp

if you want to use DHCP for eth0. You don't have to care what's running in the background. It just works.

Ok, as written in my other mail configure /etc/network/interfaces.

Yes.

Take a look at the source of ifupdown for details.
