Zentyal is a Linux distribution based on Ubuntu Server. The current stable edition is Zentyal 2.2, with Zentyal 3 as the next stable version. Unlike other distributions that release at least two versions per year, Zentyal takes a less rapid-fire development model, releasing only one stable version per year.

It is designed to perform any number of roles in an enterprise or home environment. And all the management tasks can be performed from a user-friendly, browser interface. Zentyal 3 will be based on Ubuntu 12.04 LTS. The latest pre-stable release is Zentyal 3 Release Candidate 2.

This article brings you screen shots from a test installation of this Release Candidate that show what you will get from Zentyal when the next stable version is released.

Zentyal is primarily managed from a browser interface. After installation, the first task is to determine what role you want Zentyal to play in your network environment, then install the modules associated with that specific role. As shown in the image below, there are four roles.

When you click on an icon for a server role, the Modules that will be installed for that role will be highlighted. All four server roles can be installed at the same time.

There are three editions of every Zentyal release – Community, Small Business, and Enterprise. The Community edition is available via a free basic subscription. Use it at your own risk because the are no updates, or those that are available are not assured for quality.

For a distribution with a free edition that is not certified for use in a production environment, Zentyal is not for me, but if you are willing to be a paid customer, and want to take Zentyal for a spin, you may download Zentyal 3 Release Candidate 2 from here and take a look at the Roadmap.
