I can't say about [K]Ubuntu, but both Knoppix and Kanotix don't have
root set up for login. Instead, you have to use "sudo".

I _think_ you can use sudo to change root's password, so that root then
becomes available:

"sudo passwd root"

Faithful John may also be trying to log into X/KDE as root. I believe
Kubuntu may be Debian-based, and if so, may have inherited Debian's
restrictions concerning logging into X/KDE as root (which is to say, you
can't do it in the default setup).

F.  John may also be trying to use some KDE-ified GUI for tinkering with
the network settings. I suggest not using those, and instead using the
command-line tools, as Oliver outlines below.

For DHCP, the stanza would like like this:

auto eth0
iface eth0 inet auto

I would suggest using the Debian init script:

/etc/init.d/networking restart

You might also run "lspci" to make sure the NIC is being identified; if
it says "unknown device" or something similar, you may be up a creek
without a paddle. Did Kubuntu work with the network when run as a LiveCD
rather than as a hard drive installation?
