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.
- NEW IN 0.3 - Web filtering – Enables schools to comply with local/legal restrictions on internet access for children.
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 either an XO or standard x86 based hardware.
XO
XSCE v0.3 will run on all 4 XO laptops:
- XO 1
- XO 1.5
- XO 1.75
- XO 4
In common usage, the XO may be augmented by SD cards and two off the shelf USB devices:
- Network connector – Allow the server to offer internet access to connected XO's.
- NEW IN 0.3 -- 2 USB internet dongles.
- NEW IN 0.3 -- External USB hard drive – Allows the server to provide additional storage capabilities.
X86
For greater flexibility some schools will want to use standard x86 hardware. Diligent volunteers can help make x86 and x86-64bit support increasingly real.
Deliverable
RPM
A RPM combined with tested installation instructions necessary to convert a standard XO-1.75 or Fedora-compatible x86 computer into a School Server.
IMAGE
NEW IN 0.3 -- An downloadable USB flash drive image, combined with tested installation instructions, which permit deployment staff to install XSCE software without an internet connection.
Base OS
NEW IN 0.3 -- OLPC-OS 13.1.0
GUI Later
Command line configuration/administration should eventually be discouraged as the system matures. Future target users are often not familiar with Linux system administration. Initial setup or fixing a problem with their server is not a good time to introduce system administration skill.
Modular design
One of the key design criteria of successful community-based projects is modularity.
NEW IN 0.3 -- 'plug in services'
Core Server
The core server will contain five services which can be extended via extended services.
