Skolelinux is the Debian-edu project’s Custom Debian Distribution (CDD) in development (http://wiki.debian.net/index.cgi?CustomDebian). What this means is that Skolelinux is a version of Debian whose out-of-the box environment gives you a completely configured school-network (In Norway, where Skolelinux was started, the main target group is schools serving the 6-16 years age bracket). This document describes the network architecture and services provided by a Skolelinux installation. Revision History Revision 0.1 2002-12-07 Revised by: pere Table of Contents 1.

Brief project description 2nd Conference on FS/OSS Debian GNU/Linux (http://www.debian.org/) The Debian Project is an association of individuals who have made common cause to create a free operating system. This operating system that we have created is called Debian GNU/Linux, or simply Debian for short. An operating system is the set of basic programs and utilities that make your computer run. At the core of an operating system is the kernel. The kernel is the most fundamental program on the computer and does all the basic housekeeping and lets you start other programs. Debian systems currently use the Linux kernel. Linux is a completely free piece of software started by Linus Torvalds and supported by thousands of programmers worldwide. However, work is in progress to provide Debian for other kernels, primarily for the Hurd. The Hurd is a collection of servers that run on top of a microkernel (such as Mach) to implement different features. The Hurd is free software produced by the GNU project. A large part of the basic tools that fill out the operating system come from the GNU project; hence the names: GNU/Linux and GNU/Hurd. These tools are also free. Of course, the thing that people want is application software: programs to help them get what they want to do done, from editing documents to running a business to playing games to writing more software. Debian comes with over 8710 packages (precompiled software that is bundled up in a nice format for easy installation on your machine) — all of it free. -

Experiences with CDD's: Centrally Managed Skolelinux Installations at Many Schools
Experiences with CDD's: Centrally managed Skolelinux installations at many schools Knut Yrvin Skolelinux/DebianEdu April 12th 2006 The Norwegian Ministry of Education and Research has funded a report about free software in schools. It covers planning and deployment of Skolelinux/DebianEdu that currently includes 234 Norwegian schools, 33,000 client machines, and 101,000 pupils and teachers. It covers technical issues, economics and organisation. There is also some feedback on how the teachers use free software in their teaching. The main conclusion is that no pedagogic, technical, or economic objections to using free software in schools remain valid. The numbers show that the municipalities save more by running and maintaining ICT equipment centrally at many schools. The savings are considerably larger with GNU/Linux then with Microsoft Windows. Market prices show that the most cost ecient alternative is provided by Skolelinux diskless workstations. These are at least 40% cheaper to operate than traditional workstation pools (with thick clients). Experiences from the municipalities show that running thin clients (LTSP) is more cost ecient than thick clients because it increases the lifespan of the hardware. Surprisingly, the cost of running graphical terminals such as Citrix is the most expensive solution. It is at least three times more expensive than Windows thick clients when comparing prices in the market. By using graphical clients such as Free NX the schools would incur approximately the same expenses in operating the system as with Citrix. The ICT coordinators in the various municipalities say that there are considerable challenges in introducing computer tools into schools. The management at every school must establish a maintenance regime and the teachers must learn to use computer tools actively in the learning process.
