SME Server:Documentation:Administration Manual:Chapter1 (view source)
Revision as of 16:57, 24 April 2021
, 16:57, 24 April 2021→Server version 10.x Features
The heart of Koozali SME Server is based on the GPL'd so open sources of the unsupported developer release of SME 7.0 alpha from [http://www.mitel.com/ Mitel], who are the copyright holder for much of what makes SME Server what it is. Mitel's commercial offering is known as the "Mitel Managed Application Server", and in the past it was originally conceived as "e-Smith". Mitel has been very generous to fund development of early alpha and beta versions and to keep to the spirit of the GPL by sharing their source code freely.

Koozali SME Server 10 is an RPM-based distribution that uses many packages from [http://centos.org CentOS] and [http://repoforge.org/ RepoForge]. CentOS 7 is built from publicly available open source [http://ftp.redhat.com/pub/redhat/linux/enterprise/6Server/en/os/SRPMS/ Red Hat Enterprise Linux SRPMS] and aims to be binary compatible. RepoForge is a collaborative effort of several RPM packagers that build RPMs not included with CentOS. Almost all of the packages that SME Server includes from these upstream vendors are included unmodified. The purpose of doing so is to take advantage of the stability that comes from the huge user base that uses these packages, for security, and to allow automatic updates as soon as an update is available from the upstream vendor. What Koozali adds to this solid base is easy and secure ways to adminster and manage all of it in a way that incorporates best practices and ease of use. This means that people not expert in server administration and Linux can safely manage an Internet-connected server. Security updates from Redhat/Centos should be available until 2024 for Centos 7.

=====History=====
=====History=====
* rc1 Mar 2021 - release candidate 1 of SME Server 10.0 which is based on CentOS 7.0
Originally released in 1999 as "e-smith Server and Gateway", right from the start the SME Server adopted the principles that it still follows: simplicity of administration, security by default, and using proven foundations. Originally based on the free version of Red Hat, in early production it rapidly moved to version 4.0 and was widely adopted. The e-smith company was bought-in by the Enterprise communications supplier Mitel, who offered unified office servers based upon the e-smith, renamed to "Managed Application Server", and continued up to version 6.0.
* 30 Jun 2014 - The stable release of SME Server 9.0 which is based on CentOS 6.5
Mitel later generously donated the 6.0 code base back to the community, who eventually continued with version 6.x point releases. By then development had moved to a CentOS base, the same used by Oracle Unbreakable Linux: see [https://linux.oracle.com/switch/centos/ here]. We may again opt for a new code base moving forward.
Below are listed the last few generations of Koozali SME Server still showing as in use, point releases are not included. Please note that '''only the latest release''' (v.10 pending) is supported with security updates.
'''Why "Koozali"? The word "Koozali" approximates to the Swahili for "rebirth"

* 30 Jun 2014 - The stable release of Koozali SME Server 9.0 which is based on CentOS 6.5
* 25 May 2012 - The stable release of SME Server 8.0 which is based on CentOS 5.8

Before that there was a long series of version 7:
* 4 March 2006 - The stable release of SME Server 7.0 which is based on CentOS 4.3
Early versions were published by e-smith, Mitel and contribs.org.
Documentation has been continuously developed, and the earlier releases form the underlying basis for this manual.
The current version of Koozali SME Server has moved on a very long way from its ancestors, but still follows the same core principles.
