Frequently Asked Questions Thin Clients, Linux, and LTSP An overview of Thin Client Architecture, Linux, and the Linux Terminal Server Project Frequently Asked Questions Thin Clients, Linux, and LTSP Benjamin Kudria, Tech Scout Founder, Blue Box Technical Solutions

Questions about Linux and Thin Clients “What are Thin Clients?” “What is Linux?” “Why should schools be interested?” “What are the disadvantages?” “Where can one learn more?”

“What Are Thin Clients?” Most schools maintain networks with file servers and PC workstations. Thin Client networks use servers for both applications and files. Thin client servers must be fast and high-memory, but the clients themselves can be older machines, without hard drives and minimal memory. Because thin clients boot from the network server, they cannot run stand-alone.

“What is Linux?” A Open Source, operating system available at no purchase cost, which is more secure than Windows: Immune to Viruses and other malware. Only Administrators can install programs or modify the system. Malicious users cannot harm the system. Much more impervious to crackers and hackers.

“What is Linux?” Linux contains many functional equivalents to Windows software: OpenOffice.org replaces Microsoft Office Firefox replaces Internet Explorer Gimp replaces Photoshop Freemind replaces Inspiration Students cannot download games.

“Why should schools be interested?” Linux saves money many ways: Linux is free – no Microsoft licensing LTSP (thin client technical stack) is free – no expensive Windows Server 2003 All included programs (office suite, browser, etc.) are free, although there are others that cost money. Since thin clients do not need to be powerful, legacy machines can stay in circulation.

“Why should schools be interested?” Thin Client networks are robust and secure and easy to maintain. Thin clients do not store any information, and do not need to be “cleaned”. Each client is identical to the user, and users can access their customized desktops and documents documents from any client. If a legacy machine thin client breaks, just replace it with another, with no reconfiguration.

“What are the disadvantages?” The server needs to be very fast, with high memory, or the clients run slowly. The network needs to be fast. 100BaseT is OK, but 1000BaseT (Gigabit) is better, and can support many more clients. An experienced Administrator is required to set up the server initially. Once set up, however, the server can be maintained remotely.
