SME Server:Documentation:Administration Manual:Chapter1

Welcome to Koozali SME Server 10

Congratulations on choosing the Koozali SME Server as your network and communications server!

Koozali SME Server is an open-source Linux server distribution designed to be:

• Simple to setup and use: Installation and basic configuration can take less than 20 minutes, and every standard configuration option can be set via a web-based interface.
• Secure and stable to operate: SME Server only includes what is necessary. Stability comes from using proven, supported rpm packages and from an update system that notifies you with available updates.
• Cross-platform and extendable to meet future needs: SME Server already has everything necessary to provide the core services most people need to network Linux, Macintosh, and Windows systems.
• And it's completely free!
• Download the ISO from http://wiki.contribs.org/SME_Server:Download

The heart of Koozali SME Server is based on the GPL'd sources of the unsupported developer release of SME 7.0 alpha from 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 was known as e-Smith. Mitel has been very generous to fund development of the alpha and beta versions and to keep to the spirit of the GPL by sharing their source code freely.

SME Server 10 uses many packages from CentOS and RepoForge. CentOS 7 is built from publicly available open source 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. Security updates from Redhat/Centos should be available until 2024 for Centos 7.
