Hi
I'm trying to make etherboot (without PXE emulation) to work in Edubuntu. I've replaced in dhcpd.conf: """ filename "/ltsp/pxelinux.0"; """ with """ # trick from Peter Rundle <[hidden email]>, borrowed from K12LTSP if substring (option vendor-class-identifier, 0, 9) = "PXEClient" { filename "/ltsp/pxelinux.0"; } else { filename "/ltsp/vmlinuz"; } """ When the etherboot thin client boots, it says that the kernel is an invalid image. When I copy the K12LTSP vmlinuz.ltsp to /var/lib/tftpboot and change the kernel name to vmlinuz.ltsp in dhcpd.conf, it loads the kernel fine. Any ideas on what could be different between the ubuntu kernel and the LTSP.org kernel that could cause the one to work and the other not? -Jonathan -- edubuntu-devel mailing list [hidden email] http://lists.ubuntu.com/mailman/listinfo/edubuntu-devel |
Hi,
first, why you don't want make PXE emulation ? Have you look at : http://wiki.edubuntu.org/EdubuntuDocumentation/BootingClientsWithoutPxe ? regards Jeff.

Because we're currently running 140 schools that boot using an etherboot image on a boot-rom that doesn't support PXE emulation, and booting from floppy is generally not a good idea (floppies get lost or broken). And these machines don't have hard drives so zlilo isn't possible either (and even if it were, boot-roms are still less maintenance). I asked on #ltsp yesterday and it seems that we need an mknbi patched kernel. I'll look into that again this weekend. -Jonathan -- edubuntu-devel mailing list [hidden email] http://lists.ubuntu.com/mailman/listinfo/edubuntu-devel |

Will this functionality be included in Edubuntu by default in some release down the line - without having to run any additional routines, that is. > > i couldnt test this yet, but was just given two etherboot NICs by jim > McQuillan from the ltsp guys, i'll start playing with them as soon as > i'm back in germany... That's very decent of them. cheers ed -- edubuntu-devel mailing list [hidden email] http://lists.ubuntu.com/mailman/listinfo/edubuntu-devel |
