The School Server is one of the products of the OLPC project, designed to complement the XO. It is a Linux-based OS (a Fedora-based distribution) engineered to be installed on generic low-end servers. We outline hardware recommendations and in the future, we may offer a hardware platform specially designed for the role.

When we deploy one laptop per child, we must also provide additional infrastructure extending the capabilities of the laptops. While the laptops are self-sufficient for many learning activities, other activities and services depend on the School Server providing connectivity, shared resources and services. Services, tools and activities running on the School Server allow asynchronous interaction, can use larger storage capacity, and take advantage of the processing power of the XS.

Outside of collaboration activities, the School Server provides other services to the laptops -- those services are transparent, seamless and automagic. Read more about the high level definition of the School Server.

Usage

• See the quick guide to setting up and configuring a school server.

More details are available in the following sections:

• XS Features discusses the key features and services.
• XS Recommended Hardware describes the hardware for the School Server
• XS Installing Software has instructions for installing the latest School Server images
• Read the XS Release Notes
• XS Configuration Management has aids to configuring the software for your school

You should join the server-devel mailing list, and can search its archives. There is also a dedicated IRC channel: #schoolserver on irc.oftc.net.

Development

Roadmap

The school server is in heavy development at the moment (2008) - following

• XS Core and Contrib
• XS DevKit

Technical notes

• XS-XO Interactions: how does the laptop talk to the server?
• XS Automount triggers
• XS Packaging
• XS Directory Layout for packagers
• Moodle implementation plan
• Ejabberd resource tests

Design Documents

The high-level design of the School server is described here - note that some may be slightly outdated:
