I found an LTSP list thread at http://www.mail-archive.com/ltsp-discuss@lists.sourceforge.net/msg41327.html that very closely matches my report. Near the end of the thread, Vagrant Cascadian offers the critical observation: "The Linux kernel is not finding your network card, so it probably does not have the correct kernel module or firmware in the initramfs, if that version of the kernel works with your network card at all." "I would recommend booting a live CD (or USB image) of the same OS and version you're trying to get LTSP to work on, and seeing what network drivers and/or firmware it uses, presuming it works at all." In the case of the original poster, booting the live CD confirmed that the kernel was not properly supporting his network card. In my case however, when I boot the live CD on a client, my 3Com card is supported just fine (and uses the 3c95x driver). ----------------------------------- My LTSP server syslog has some interesting entries, though my untrained eye does not conclude anything definitive.
