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? Paul Abrahams
