'''NOTE:''' This software is currently in a '''pre-alpha''' state. This means that you probably won't be happy with it unless you enjoy helping to track down bugs. If you're looking for something production-ready, head over to the [http://www.ltsp.org/ LTSP] site.

== Requirements ==

You will need:

 * An Ubuntu "breezy" system to be the server (the current development branch, to be released in October 2005)
 * At least one PXE-bootable system to be a client
 * A bunch of disk space
 * A fast network connection, or a local Breezy mirror, or some patience
 * A DHCP server which is capable of supporting PXE clients, or a separate network segment where you can run a dedicated DHCP server
 * Command-line familiarity
 * A sense of adventure
 * A burning desire to send feedback to [mailto:ubuntu-devel@lists.debian.org ubuntu-devel]

== Getting Started ==

 1. Set up the DHCP server
  * If you have an existing DHCP server which can support PXE clients:
   * Configure it to pass a boot filename of `/ltsp/pxelinux.0` and a root path of `/opt/ltsp/i386`
   * For ISC DHCPD, use the following options: {{{
filename "/ltsp/pxelinux.0";
option root-path "/opt/ltsp/i386";
}}}
   * Install `ltsp-server` on the server: {{{sudo apt-get install ltsp-server
}}}
  * If you want to run a dedicated DHCP server on the thin client server:
   1. Install `ltsp-server-standalone` on the server: {{{sudo apt-get install ltsp-server-standalone
}}}
   1. Replace `/etc/dhcp3/dhcpd.conf` with the following contents, or adapt to your needs: {{{
authoritative;
subnet 192.168.0.0 netmask 255.255.255.0 {
  range 192.168.0.20 192.168.0.63;
  option domain-name-servers 192.168.0.1;
  option subnet-mask 255.255.255.0;
  filename "/ltsp/pxelinux.0";
  option root-path "/opt/ltsp/i386";
}
}}}
 1. Build the thin client runtime environment: {{{sudo ltsp-build-client
}}}
  * This script is hardcoded to use a particular Ubuntu mirror, so you may wish to edit it if you have a nearby mirror
 1. Check `/opt/ltsp/i386/etc/ssh/ssh_known_hosts` and ensure that your host key is associated with your host's IP address. Depending on your `/etc/hosts` configuration, this may not always be correct automatically (yet). If it looks like this: {{{
servername ssh-rsa AAAAB3NzaC1yc2EAAAABI...
}}} then add the IP address like this: {{{
servername,192.168.0.1 ssh-rsa AAAAB3NzaC1yc2EAAAABI...
}}}
 1. Optionally, create `/opt/ltsp/i386/etc/lts.conf`. If you don't create one, reasonable defaults and auto-detected values will be used.
 1. PXE boot the client and see what happens. If all goes well, you should see a (very ugly) graphical login dialog.
 1. Log in, with any user authorized to login remotely via ssh, and see what happens. If all goes well, you should get a working desktop session on the server.
 1. Send mail to [mailto:ubuntu-devel@lists.ubuntu.com ubuntu-devel] with your findings
