AbulÉdu is a Ubuntu-based distribution for primary schools. It is currently in French but most of the tools can be translated. An AbulÉdu server can handle Mac, Windows (samba), GNU/Linux and X terminal (with LTSP) clients. The server acts as a central gateway for Web, mail, and printing, and facilitates the management of classes, pupils, and teachers. Everybody can publish Web pages on an intranet using Apache and all administration tasks are performed using a browser. The result is that a teacher who is not a computer specialist can install and manage a school network.
