Not so long ago I've discovered few bad sectors on one of my machines hard disk. The failing component warranty hasn't expired but I was reluctant to take it back to my hardware dealer because that would make this machine unusable until the whole process is finished. Hard disk device in question is currently in my hardware dealers hands an I'm waiting for replacement but that hasn't stopped me from writing this article using diskless machine in question. In this article I'll show you how to install LTSP (Linux Terminal Server Project) on your Ubuntu PC and how to configure this system for booting thin clients over network using PXE (Preboot Execution Environment).
