    Yesterday I did a Yast online update, which seemed to go uneventfully.
    However, it included a new version of the kernel, with the note that I should
    reboot the system after the install was completed. I did so but then (as I
    remember) walked away from the machine and left it running overnight without
    doing anything more.

    Today I came back to find that I had no network connection -- all addresses
    were unreachable. The little light next to the ethernet jack was on, and the
    lights on the hub to which the machine directly connects were also on. I
    tried (in Yast) uninstalling and reinstalling the network interface card;
    that had no effect.

    I can think of four possible causes for the failure:

    1. The Ethernet hardware failed some time during the night.

    2. There's a cabling problem (other machines on the net are working fine).

    3. There's a software problem induced by the online update.

    4. There's some other software problem.

    Any suggestions on how to go about diagnosing the failure?
