eBox Platform is an open source distribution and development framework, based on the GNU/Linux operating system, intended to manage services in a computer network.

It offers a layer of abstraction and management, accessible through a simple web interface, and also a simplified development environment for new features or customization.

eBox is licensed under GPL and started as an open-source, collaborative project of two companies.^[1] It also takes part on Morfeo Project.^[2] On 16th November 2006 eBox was officially approved as a NEOTEC project, receiving public funds from the CDTI (a Spanish public organisation, under the Ministry of Industry, Commerce and Tourism) to complete the development of version 1.0.^[3]

Ubuntu Gutsy Gibbon Tribe 3 featured eBox as "network services control tool".^[4]

[edit] Development

eBox Platform uses an open source model, with all the source code available for its users.

[edit] Design

eBox is a web application using Apache webserver with mod_perl as foundation and Mason components as building blocks, mainly written in object oriented Perl, with some Javascript for visual improvements.

Its design incorporates modern programming techniques as:^[5]:

Design patterns: an Observer design pattern is used mainly to integrate different modules across eBox Platform. E.g. each service reports about which ports it needs to be open. Besides this, a Singleton holds global configuration and behaviour details.
Presentation and logic decoupling: user interface uses CSS and Ajax, and include several Mason components, as a generic table used to configure services. Program logic is held inside library packages and CGI-like code.
Fault tolerance: errors and warnings are managed through software exceptions, flowing from core to its handling routine.

It also offers debugging facilities, integrating the layout of the execution stack of the Perl 5 interpreter.

Each service's process is monitored so if it dies, it is respawned automatically.

[edit] Open Source Components

eBox is built upon common Open Source components:

Apache
- Webserver
mod_perl
- CGI engine
OpenLDAP
- Shared users and groups
OpenSSL
- Cryptography
Netfilter/iptables
- Firewall
- NAT
BIND
- Domain name server
Squid
- Web proxy-cache
DansGuardian
- Content filtering
Postfix
- Mail server
Jabberd
- Instant Messaging
Ntpd
- Clock and date synchronization
OpenVPN
- Virtual Private Network
Samba
- Shared storage
- Primary Domain Controller for Windows clients
Common Unix Printing System (CUPS)
- Shared printers
Advanced Packaging Tool (APT)
- Software installation and upgrade

The main programming language used is the Open Source Perl, on top of Mason engine.

Documentation uses Docbook-XML to generate HTML pages. API reference uses Natural Docs.

eBox Platform Live CD is built using Morphix. The whole distribution uses Debian and Debian Installer for non-live media.

[edit] Community

Main eBox community work and support takes place at eBox users' mailing lists, with an English speaking and a Spanish speaking one.

eBox's inclusion on Ubuntu Gutsy Gibbon was preceded by some comments at Ubuntu Forums community.^[6]

There is also a very active group of Linkstation users which succedeed in porting eBox to PowerPC.^[7]
