LTSP How To

Upstream documentation with official, detailed information about installing LTSP is at http://wiki.ltsp.org/wiki/LTSPedia.

Installing LTSP on Lenny

  1. If you want a complete LTSP server with all the bells and whistles:

    apt-get install ltsp-server-standalone

    If you want more fine-grained control, splitting some services off to separate servers, you can install ltsp-server instead, and manually install each of the other services.

    (you can also get backported packages for lenny: LTSP/Howto/Lenny-With-Backports)

  2. Build the LTSP client environment:

    ltsp-build-client

ltsp-build-client uses the Internet to fetch packages.

In case you got backported packages at step 1., it is strongly recommended to use backports packages too to build client, or you may have incompatibilities (bad ldm version, login failed...). Please, use the following command:

 ltsp-build-client \
  --backports-mirror "http://backports.debian.org/debian-backports" \
  --apt-key /etc/apt/trusted.gpg

(details: LTSP/Howto/Lenny-With-Backports)

In case your thin clients are old, please use the following parameter:

 ltsp-build-client \
  --arch i386

In case you have a slow Internet connection or want to use Local DVDs of Debian. Please use the following command:

ltsp-build-client --mirror file://mnt/Debian_Lenny_Bluray_Image.img --security-mirror none --accept-unsigned-packages

Since the ltsp-build-client uses more than one Debian DVD you would need to build a ?BluRay Image using the jigdo template of ?BluRay Disc. This Image location can be passed as the argument. The security-mirror-none option prevents updates from being downloaded. The accept-unsigned-packages allows the building to go on even using unsigned packages.

Customizations in the chroot

Two important configuration files inside the client are /var/lib/tftpboot/ltsp/i386/lts.conf (or /opt/ltsp/i386/etc/lts.conf for NFS) and /opt/ltsp/i386/etc/default/ltsp-client-setup. See the examples in /opt/ltsp/i386/usr/share/doc/ltsp-client*.

See also see the Edubuntu wiki http://doc.ubuntu.com/edubuntu/edubuntu/handbook/C/customizing-thin-client.html (note: Debian LTSP still uses NFS by default).
