Installing from Scratch
First, you will need an Ubuntu Alternate CD. For this example, I took a classic 10.04 i386 ISO from here. In case you don’t know, an alternate CD is like the regular one but without the fancy interface for installing Ubuntu, and it lets you access more options. Among these is the ability to hit F4 at boot to select “Install an LTSP server” from the different modes.
The installation will then take as usual when an alternate CD is used:
Select your language Select your country Select your keyboard layout (automatically or manually) The DHCP will configure itself Choose a host name
Set the clock Select your partition system (full disc, partial, encrypted, etc.)
The installation will begin. It can take a few minutes As usual, choose a user name and a password
Decide if you want to encrypt your /home The image will be compressed
And finally, the GRUB boot loader will be installed
And that’s it. You can now reboot and connect your first thin client. Notice that even if the automatic installer is great, some manual configuration may be needed in some cases.
I advise you to take a look at “/etc/ltsp/dhcpd.conf” and “/opt/ltsp/i386/lts.conf” for the advanced settings. The LTSP Wiki is very informative. If you want to transform your computer into a thin client server without having to re-install everything, LTSP can also do that. Simply install the required packages: And then launch the automatic configuration process via It will take some time to retrieve and install everything.
It did not work out for me the first time but it was probably due to the bad Internet connection, so don’t hesitate to retry in case of failure. However, bear in mind that some manual configuration will generally be needed here. You can finally launch your server with
Conclusion
As I said earlier, LTSP can be installed on a plethora of other distributions, so you can pick your own if you want. Ubuntu can be considered as the standard for a tutorial but each distribution’s wiki is very precise and a lot more detailed. As a last piece of advice, you should check that your thin clients can be booted from the network because it is really a pain to do it manually if you have more than ten of them. Would you pick another distribution to install LTSP on? Or would you choose something completely different from LTSP in the first place? Let us know your opinion in the comments.
