Lan Core is a free and open source software that lets you to build a thin client network on a Windows operating system. It was originally designed to work in a server or workstation (see Frequently Asked Questions) with Windows XP Professional and using the native remote desktop protocol or RDP (see how to configure multiple remote desktop sessions in Windows). To this end, the Lan Core package includes:

  • First, the Preboot Execution Environment or PXE service. A server application used to boot the thin clients, also referred as terminals or clients, in a local area network.

  • Second, the thin client operating system (Thin OS). An embedded system based on Linux.

  • And finally, an interface application used to manage the PXE service and thin clients.

The thin clients' boot is done through a local area network or LAN, and it is based on the Preboot Execution Environment (PXE) protocol commented above. In order to do it Lan Core also provides two additional services: a DHCP and a Trivial FTP server for Windows, both used for IP address assignment and transfer boot files, respectively.

Currently, Windows XP Professional is the version of the operating system most commonly used to build a thin client network with Lan Core (note that Windows XP Home does not provide natively remote desktop services). However, Lan Core also works in other Windows-based operating systems, such as Windows 2000 or Windows 2003 Server, among others. By default, thin clients work connected to those Windows systems using the native remote desktop protocol (RDP), but other protocols (e.g. VNC, ICA, etc.) are also available.

Nowadays, we are also working on a Thin Client solution based on a Linux server using XDMCP and NX technology. Any help is greatly appreciated!

Please let us give you three reasons to use Lan Core:

  • You do not have to pay for it, because it is free.

  • You can modify it as you wish, because it is open.

  • And you can use it for ever without limits, because it is a complete solution.


Lan Core in Africa! Members of the university cooperation for development group TEDECO (Technology for Development and Cooperation) have installed several computer labs, classrooms and a cyber based on thin client technology in the University of Ngozi (in Burundi) using Lan Core.

Do you know other University or institution that may be interested in Lan Core? Please tell us, we are expecting for new initiatives to further improve this implementation.
