    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?
