Thin Client How-To
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. There is a manual on this wiki - see ["LTSPHowTo"].
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
- 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 have an existing DHCP server which can support PXE clients:
}}}
- If you want to run a dedicated DHCP server on the thin client server:
Install ltsp-server-standalone on the server: {{{sudo apt-get install ltsp-server-standalone
}}}
If necessary, customize /etc/ltsp/dhcpd.conf (by default it's configured for a server at 192.168.0.1 serving PXE clients)
- 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
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...
Optionally, create /opt/ltsp/i386/etc/lts.conf. If you don't create one, reasonable defaults and auto-detected values will be used.
- PXE boot the client and see what happens. If all goes well, you should see a graphical login dialog.
- 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.
