What are "Thin Clients" ?

Diskless-clients are just one method of connecting computers together to form a network (lab).

Workstations are referred to as diskless-clients or "thin-clients" since most of the processing is performed by the server, and routine tasks (like accepting input from mouse & keyboard and displaying graphics on monitor) are performed just in the thin client's internal memory (RAM).

Advantages of Using Diskless Workstations:

• Save money on hardware (use older machines as workstations, purchase one powerful central server)
• LTSP is distributed under GPL (Gnu Public License) and will always be free
• Ease of upgrading or installing software on central server instead of creating and installing images on multiple machines...
• Thin client workstations are reliable (I have seen this with my own eyes)
• Reduced vulnerability from viruses

What is LTSP?

LTSP stands for (Linux Terminal Server Project). Here is a link to their website: ltsp.org

LTSP is a free application to connect older (legacy) machines to act as "workstations" which are connected to a central computer...

The technology was developped by Jim MacQuillan, who is the inventor and project leader of LTSP.

Seneca College's Involvement in LTSP

Since 1998 one of my colleagues at Seneca College, John Selmys, experimented with a technique to cost-effectively connect old "junky" computers that did not have a hard disk drive to a more powerful computer server. When that computer department moved in 2005, it was discovered that those "ancient" machines were still being used by students to work on their assignments / perform homework...

Seneca College, over the past 6-7 years have supported Seneca staff to start projects to donate, install, and support several high-schools in the Toronto area that are in need of affordable networking solutions. I was one of the people involved in this project. I also have volunteered to help set up a Linux lab for a church in Orangeville, Ontario...

Here are some pictures of the Linux Computer Labs we helped to set up:
