School Server - Community Edition 0.3 Project Specifications
Summary
The school server is very similar in concept to a standard home wireless router. In everyday usage it provides various services which extend capabilities of the connected laptops while being totally transparent to the user. These services can include:
- Network connection – various services similar to what you would find in a home router.
- Presence server – Augments sugar's native collaboration functionality.
Reference User
The XS-CE has two different types of reference user:
- Skilled sysadmins running micro-deployments
- Mid-sized deployment with limited onsite sysadmins
Hardware
School servers can be run on an XO.
XO
XSCE v0.3 will run on all 3 types of XO laptops:
- XO 1.5
- XO 1.75
- XO 4
In common usage, the XO may be augmented by two off the shelf USB devices and a local access point:
- Network connector – Allow the server to offer internet access to connected XO's via a wired access point.
- NEW IN 0.3 -- a second USB internet dongles for wired connection to a wide area network or internet service provider.
