Linux Terminal Server Project

TCM

See http://doc.ubuntu.com/edubuntu/edubuntu/handbook/C/ltsp-tcm.html. To install:

sudo apt-get install thin-client-manager-gnome
sudo student-control-panel

Floppy, cdrom, usb netbooting

For each boot method, set up DHCP like normal

First download the source code from the Etherboot website.

Then unpack the tar ball, or go into the src directory.

Floppy

make bin/gpxe.dsk

Transfer the image to a blank floppy disk using

dd if=bin/gpxe.dsk of=/dev/fd0

where /dev/fd0 is your floppy disk drive. Note that this will erase any information currently on the disk.

Creating a bootable CD-ROM

make bin/gpxe.iso

Use your usual CD-burning program (e.g. cdrecord, k3b, etc.) to burn the bin/gpxe.iso image to a blank CD-ROM.

Creating a bootable USB key

make bin/gpxe.usb

Transfer the image to a blank USB key using

dd if=bin/gpxe.usb of=/dev/sdX

where /dev/sdX is your USB key.

Note that this will erase any information currently on the USB key. Make sure that /dev/sdX really is your USB key, and is not your real hard disk!

How to recognize the device of your usb stick?

  1. Plug in usb stick
  2. Type in a console
    dmesg
    [4136684.193139] usb 5-6: new high speed USB device using ehci_hcd and address 4
    [4136684.326026] usb 5-6: configuration #1 chosen from 1 choice
    [4136684.350681] scsi5 : SCSI emulation for USB Mass Storage devices
    [4136684.354302] usb-storage: device found at 4
    [4136684.354307] usb-storage: waiting for device to settle before scanning
    [4136689.350674] usb-storage: device scan complete
    [4136689.351299] scsi 5:0:0:0: Direct-Access              Flash Disk       5.00 PQ: 0 ANSI: 2

    [4136689.363407] sd 5:0:0:0: [sdb] Write Protect is off
    [4136689.363411] sd 5:0:0:0: [sdb] Mode Sense: 0b 00 00 08
    [4136689.363414] sd 5:0:0:0: [sdb] Assuming drive cache: write through
    [4136689.365897] sd 5:0:0:0: [sdb] 247808 512-byte hardware sectors (127 MB)
    [4136689.366772] sd 5:0:0:0: [sdb] Write Protect is off
    [4136689.366777] sd 5:0:0:0: [sdb] Mode Sense: 0b 00 00 08
    [4136689.366780] sd 5:0:0:0: [sdb] Assuming drive cache: write through
    [4136689.366785]  sdb: sdb4

    [4136689.368142] sd 5:0:0:0: Attached scsi generic sg2 type 0
  3. Then you will see the device. Here it is sdb
  4. Then umount the device
    umount /dev/sdb
  5. Then write the usb image to the usb stick.
    dd if=/path/to/gpxe.usb of=/dev/sdX
