The Linux Terminal Server Project adds thin-client support to Linux servers. LTSP is a flexible, cost effective solution that is empowering schools, businesses, and organizations all over the world to easily install and deploy desktop workstations. A growing number of Linux distributions include LTSP out-of-the-box.
Shiny new thin-clients and legacy PCs alike can be used to browse the Web, send e-mail, create documents, and run other desktop applications. LTSP not only improves Total Cost of Ownership (TCO), but more importantly, provides increased value over traditional computing solutions. LTSP workstations can run applications from Linux and Windows servers.
Linux thin-clients have proven to be extremely reliable because tampering and viruses are virtually non-existent. It's distributed under the GNU General Public License, meaning it's free and always will be.
