ClearOS Community 6 Released

Posted by on in ClearFoundation

ClearOS Community 6 has arrived!  A lot of time, resources and development have gone into making ClearOS the best next generation small business server and gateway.  The underlying framework was redesigned to make it easy create new and innovative apps.  The new Marketplace now provides a quick way to install both open source and paid apps.  There's also 64-bit support, a shiny new graphical installer, improved usability, better VM support, a modernized build system, and the migration to the latest upstream 6.x version.  Whew.

We stepped back, improved the architecture and software, and are now ready to bring you a slew of new apps in 2012.  Here's what to expect in just the next few weeks:

  • Zarafa Community and Small Business Edition (beta testing starts next week!)
  • Wireless Support
  • Reporting
  • Media Server

We would like to thank the entire community for the hard work, feeback and testing.  Once again, ClearOS would not be possible without a vibrant community behind it.  Thank you, and then thank you again!  There's no need to wait, go ahead and install it today:

We would also like mention that ClearOS Professional 6 is now available.  Along with the improved underlying ClearOS platform, the following new paid apps are available in the Professional Edition:
  • Active Directory Connector
  • Google Apps Synchronization
  • Account Synchronization (Master/Slave)
  • Antimalware Premium powered by Kaspersky

An announcement on the Professional release will be made shortly.

ClearOS Community 6.2.0 Beta 3 Released

Posted by on in ClearFoundation

ClearOS Community 6.2.0 Beta 3 has arrived! Along with the usual round of bug fixes and enhancements, Beta 3 includes the following new apps: Content Filter, Flexshare, Samba, Remote Server Backup, Print Server, Password Policies, and Network Visualizer. New apps in the Professional Edition include: Google Apps Synchronization, Active Directory Connector, and Central Management. This will be the last beta as we head toward a final release. We will soon be able to put those Duke Nukem jabs behind us ;-)

For those of you who missed the recent announcement, ClearOS now comes in two different flavors: Community and Professional. That “Enterprise” name was a holdover from the old days and it has always caused some confusion (we heard you Ladislav).  In retrospect, we should have made all these changes when ClearOS absorbed the old ClarkConnect Edition.  No matter, time to move now that we have better product names.  The Professional Edition includes technical support and is intended for businesses, education, non-profit and other professional organizations. The Community Edition has all the old Enterprise features and is intended for less critical environments: home, Linux shops, and just plain old open source hacking. You can read the gory details on this topic in an earlier blog post.




ClearOS Community and Professional

Posted by on in ClearFoundation

With the release of ClearOS 6 drawing closer, we'd like to update the community on the continued evolution and direction of ClearOS.

ClearOS 6 marks a significant step forward on two fronts to engage developers and ISV's currently outside the ClearOS community to develop on the ClearOS 6 platform:

  • the new webconfig framework
  • ClearCenter's Marketplace.

Webconfig Framework

The re-factoring of the ClearOS 5 webconfig code to utilize a more modern, secure and extensible PHP/UI framework (CodeIgniter and Jquery/JqueryUI was chosen) will assuredly make new developers to ClearOS feel more 'at home' and be productive faster than learning a completely custom API.  In addition, significant resources were allocated towards documenting the development process and creating tools to lower the barrier to entry to new developers and OSS projects/ISVs interested in integrating into ClearOS.




ClearCenter's Marketplace

Modules (renamed apps in ClearOS 6) in ClearOS 5x essentially originated from a very small pool of developers - 95% of which worked for ClearCenter.  With the new ClearCenter Marketplace, a framework exists for developers and companies outside the core development team to easily (and very visibly) have their contributions adopted by the ever-growing ClearOS install base.  Marketplace not only abstracts away from the developer the tasks of marketing, downloading and installing apps - it also provides a variety of business models in which to do so.  The Marketplace will have both free and paid apps, supported and unsupported, all at the discretion of the developer/vendor.

The Future of ClearOS - Two Versions Today - More to Come!

With a common framework and Marketplace in place, the ClearOS platform can evolve towards markets currently being under-served.  For example, a Home Edition has been discussed on the forums in numerous threads but the lack of apps specific to home use (media servers, home security, home automation etc.) have yet to warrant a separate image (i.e. ClearOS Home Edition).

The team at ClearCenter (the single largest commercial organisation supporting ClearOS) feels now is the right time to differentiate the solution specific to ClearCenter's focus - small/distributed business, education, NGOs and government.

To accommodate and future-proof against these changes, ClearOS Enterprise Edition 5x will be renamed ClearOS Community Edition in 6.x and beyond, to more aptly reflect the development model and support processes in play.

At the same time, a second product ISO will be launched by ClearCenter, named ClearOS Professional.  This image will share much of the same code-base and OSI licensing as the Community Edition.  The main differences (explained in more detail when ClearCenter officially announces the release) will be the 'built-in' commercial support and a Marketplace that includes all the apps in the Community Edition in addition to half a dozen or so apps that will be exclusive to the Professional Edition.  In addition to simplifying the messaging and providing more clarity to new users of ClearOS, this change was necessary to adequately support and maintain the apps focused on installations where there is a business-case to do so.

To existing assured no functionality is being removed in the move from version 5 to version 6.  All apps entering the Professional Edition Marketplace are new features that represent time invested by the ClearCenter team and/or partnerships ClearCenter has made with ISV's (i.e. Google, Kaspesky, Zarafa etc.).  Those apps are:

Active Director Connector
Google Apps Syncronization
Kaspersky Antimalware (for file, email and gateway)
Zarafa Small Business
Central Management

A forum thread for further discussion on this topic has been created and available here.




ClearOS Enterprise 6.2.0 Beta 2 Release Information

Posted by on in ClearFoundation

ClearOS Enterprise 6.2.0 Beta 2 has arrived!  Hey, what happened to the version number - wasn't it version 6.1.0?  Well, the latest ClearOS release is built on source code from a prominent North American Linux vendor.  This upstream vendor released their 6.2 update earlier this month and we quickly followed suit.  For the curious, you can find more information on ClearOS version numbering here.

Along with the release of more than a dozen new apps, this release continues the process of creating a stable base system: installer, RPM packages, users, groups, system tools, LDAP, network, firewall, framework, and Marketplace.

You can find download information for both 32-bit and 64-bit versions in the Release Notes.  Enjoy!

ClearOS Enterprise 6.1.0 Alpha 1 Released

Posted by on in ClearFoundation

The ClearOS Enterprise 6.1.0 alpha 1 release has arrived!  This alpha provides a small window into what's in store for the upcoming release.

For end users, Marketplace, the fast web interface engine and usability improvements are the highlights of this release.  The Marketplace is up and running and a small set of apps can be installed.

For developers, the new ClearOS App Framework is now stable and ready for use. Whether you want to develop a free tool or a paid app, the environment for building new features for ClearOS is much improved.

For translators, the process of translating ClearOS Enterprise can get underway. Please contact if you would like to participate!

Please keep in mind that this is an alpha. Some parts of Alpha 1 are quite polished, while other parts (ahem) need work.

ClearCenter Marketplace for ClearOS Enterprise

Posted by on in ClearFoundation

With the ClearOS Enterprise Alpha (and shortly thereafter, Beta) image nearing release, there are bound to be questions on one of the major features making its debut in the upcoming release - ClearCenter's Marketplace.

Simply put, ClearCenter's Marketplace is an online store featuring apps and services (both free and paid) for ClearOS Enterprise.  For those using or familiar with Android smartphones, there is a good analogy that will help clarify the direction we are taking.  Let's start with the following two premises:

1.  ClearOS is to Server, Network & Gateway what Android OS is to Smartphones.

2.  ClearCenter's new Marketplace is to ClearOS Enterprise (the platform) what Google's Android Marketplace is to Android OS.


There's no place like home...

Posted by on in ClearFoundation

A couple years ago we were trying to decide the organizational structures of ClearCenter and ClearFoundation. We knew that we had a business to run but we also knew that the open source components that made Clarkconnect unique needed greater community incubation. This is the reason for placing ClearOS Enterprise into ClearFoundation and ClearSDN with ClearCenter. We knew it would be trivial to create ClearCenter but ClearFoundation was a bit different. Let me explain.

Michael Proper introduced me to Clarkconnect when I was working at his Managed Service Provider company. He was doing due diligence to try to find a low cost office solution for small businesses. In the course of his search he discovered Clarkconnect and introduced it to me. I had the same reaction that nearly every Linux admin has, "Well, it's great and all but I can set all that up too." Michael's response to me changed my view and opened my eyes. He said something to the effect of "Yeah, but can you create this same configuration a hundred times, all the same, and then support them?" It was this scalability and the 'set it and forget it' aspect that won me over.

Next door to this company was a little outfit engaged in a lawsuit with IBM by the name of SCO. As our involvement with the Clarkconnect team grew tighter and tighter, we realized that to protect something that is fundamentally protected by copyright alone (as it should be) we needed to keep it safe and untainted. In our search we considered some great places like Canada,  Australia, Switzerland, Singapore and even the Principality of Hutt River. In the end we decided on New Zealand. Over and over this island nation has proven a rational understanding of innovation in software as something that can and should be copyrighted but not patented. Additionally, it grants freedoms to businesses better than nearly any other nation. So, we give a shout out today and cheer to New Zealand. Let those that would seek to implement software patents there join the ranks of those that have decided to back down. Long live New Zealand, home of ClearFoundation! Hip Hip Huzzah! And thank you NZOSS and NZCS for all your hard work.


ClearOS Core vs. ClearOS Enterprise ... what's the diff?

Posted by on in ClearFoundation

If you are confused, it is my fault. I take the blame and I'm sorry. The recent releases of ClearOS Core is causing some confusion and I know why. If you have read every post on all the forums then it is easy to see what is going on but a cursory glance will lead to confusion so I will attempt to spell it out simply. ClearFoundation is releasing a completely different distro (ClearOS Core) and to make matters worse, we are calling nearly the same name as another existing product (ClearOS Enterprise). This was done for strategic, long term consistency between multiple product lines and makes way for yet another goal, ClearOS Home.

If you are used to using ClearOS Enterprise and you remember the days of Clarkconnect then by now you know that sometimes we mix things up and it can cause to some confusion. For example, ClearOS Enterprise used to be paid and now it is free like Clarkconnect Community Edition, which was free but now no longer exists, much like Clarkconnect SOHO or GS (which you probably never heard of). Back then the question was, "Wait, why are you getting rid of the Community Edition, man!" The answer was "Well Enterprise is now free!". To which the reply was, "But I like the Community Edition." ... good times.

For existing users familiar to the interface, ClearOS Enterprise is the only thing you need to concern yourself with. ClearOS Enterprise is a continuation of what most people consider 'ClearOS'. So if you are looking for a server, network and gateway platform that is managed through a web-based interface, ClearOS Enterprise is the tool for you. The alpha release of ClearOS Enterprise should be available as a VM shortly.

So what the heck is ClearOS Core? For a long time we have been anticipating the release of open source code from CentOS which would allow ClearOS Enterprise to move forward with a better kernel, improvements to the driver stack and other bits that make geeks chitter with glee, bob their heads in approval, and strum their fingers together signalling imminent world domination. Sadly, our primary source of this code has not been forthcoming in a manner that met our expectations. Our answer to this was to bypass them and go further upstream. We have retooled our development resources to handle this mammoth project and decided to give it away as well. The end result is a vanilla multi-purpose Linux distribution that is not easy to manage but is great for Linux hobbists and elite Linux admins. A CentOS replacement. With nothing better to do than to confuse our patient fans we decided to call it ... ClearOS Core! I realize now that this is akin to U2 calling the followup to their smash hit album, "The Joshua Tree Leaf". I'm sorry for confusing anyone.


ClearOS Core 6.1 Alpha1 released

Posted by on in ClearFoundation

ClearFoundation announces the release of ClearOS Core 6.1 Alpha 1. This release is intended for testing and proof of concept for new line of operating systems for servers and workstations. To download the torrent please visit the download section or visit

ClearOS Core is an enterprise Linux distribution for server and desktop environments. It is a free and open source rebuild of a prominent North American Linux distribution. The goal is to provide near binary equivalency and functionality that exists in the upstream distribution, including bugs. Additionally, ClearFoundation strives to release versions, updates and patches in a timely and professional manner (the goal for updates is 48 hours or less). Most of the source code in ClearOS Core is GPL. ClearFoundation reserves all rights on its own service marks, trademarks and graphics not specifically designated as open source.

ClearOS Core is the result of the hard work of many individuals worldwide who have given their time and talent to open source. ClearFoundation is grateful for the dedicated efforts of our upstream sources provider. ClearFoundation is not affiliated, associated or supported by the company which produces the upstream prominent North American Linux distribution or the Fedora™ Project. ClearOS Core is built from publicly available and open source SRPMS and as such it is an alternative and not an exact replacement to the prominent North American Linux distribution.

ClearOS Core is the base for ClearOS Enterprise. It is intended for advanced Linux administrators who want a high level of scalability and control over their Linux environments.



Request for ClearOS Mirrors

Posted by on in ClearFoundation

With the release of ClearOS Core the ClearFoundation will need global mirrors (see the TBD section) to help with the distribution effort. We are looking for sites with 100GB available that have a 100Mbps connection, 1Gbps preferred. We hope to be pushing content during the coming month. Sign-up here to help.

ClearOS Enterprise and ClearOS Core

Posted by on in ClearFoundation

ClearFoundation is excited for the latest release of new upstream sources. We are grateful to hardware providers that enable us to rebuild these sources quickly. Since we are already building sources for our expected release of 6.0 we have merged the newly released sources and have already begun rebuilding our 6.0 tree against upstream 6.1 sources. At the time of this writing, we are already nearly complete in our build from sources. This has turned out to be great timing for us as we will soon be able to place these packages into beta for the community for testing.

We are excited to announce that in conjunction to the release of ClearOS Enterprise 6.0 that we will also be releasing a new distribution, ClearOS Core 6.1. This new distribution strives to maintain 100% package compatibility with upstream sources.  100% compatibility means

ClearOS Core will also contain all upstream issues and bugs.  The only changes from upstream sources will be to remove branding as required.

Beginning tomorrow, we will begin our internal QA process to validate the symbols. ClearOS Core 6.1 will be based on these 6.1 upstream sources. ClearOS Enterprise 6.0 will enter beta using the sources we have previously built against upstream 6.0 sources. During the beta we will 'update' to these new sources and hope to have them merged by the completion of the beta cycle. We expect to release code into beta shortly for both products.

ClearOS Core and ClearOS Enterprise are free and open source platforms. ClearCenter continues to provide paid resources such as support, hardware, and services for ClearOS. Volunteer today!


Going Back To Our Red Hat Roots

Posted by on in ClearFoundation

ClearFoundation announces the development of an open source application repository to provide pre-built packages for ClearOS and other related Linux distributions. 

ClearOS Distribution Timeline

This application package repository will be used in conjunction with newer distribution models to provide enterprise grade application frameworks for businesses, education, research and homes. This repository will contain packages built from Red Hat Enterprise Linux sources. 

Initially the repository will contain over 2000 open source applications, modules and components. These can be used to build custom solutions based on ClearOS or other related Linux distributions. Packages will range from very foundational Linux code to productivity applications. ClearOS and other open source communities will benefit from the repository by having access to timely updates and quick turn around for sources. 

The ClearFoundation will be seeking developers, maintainers, testers, bandwidth contributors (hosting mirrors) and additional funds for additional build hardware. If you are any of the above and would like to join this important effort please fill out this form.

* Company names, brand names, trademarks and logos are the property of their respective owners.


New installer slated for ClearOS 6.0

Posted by on in ClearFoundation

With the upcoming release of ClearOS 6.0 there will be a new graphical installer. This installer will be more flexible than previous versions and will support Linux Volume Manager (LVM) and Kickstart. These additions bring greater robustness, flexibility, and scalability to the ClearOS platform. 

Category selection in Graphical interface

LVM allows administrators to grow and shrink partitions. Additionally, partitions can be dynamically manipulated. 

LVM Administration in ClearOS 6.0 installer

Kickstart allows administrators and system integrators to create custom installs to 'preconfigure' ClearOS with parameters, settings, and even third party applications during the install. An example of this would be an unattended VMWare server install or an installation of packages or modifications of ClearOS settings.

Lastly, as we try to improve localization and translation, we will need some new elements created in various languages. If you have previous translation experience, we need you!


ClearOS Enterprise 6.0 Developer Preview

Posted by on in ClearFoundation

Just in time for the holidays!

As most of you already know, much of ClearOS 6.0 will be built off of source code from the Red Hat Enterprise Linux 6 and CentOS 6 releases.  The new Red Hat version was more than 3 years in the making and was just released a few weeks ago (November 2010).  There are a lot of new goodies in the new release - especially for the enterprise - and you can read about them here.

The CentOS team went to work the day of the Red Hat release and is busy putting together CentOS 6.  Though the base CentOS 6 is not yet ready, that has not stopped us from providing a sneak preview of the new ClearOS 6.0 web application framework!

ClearOS Enterprise 5.2 Service Pack 1 Released!

Posted by on in ClearFoundation

October is here and so is Service Pack 1 for ClearOS Enterprise 5.2!  We have added a couple of new features in this release:

  • The ability to enable services (for example, Content Filter Updates) on the fly.
  • The ability to install software modules from the ClearOS community and third party vendors.

The third party software modules integration in the service pack is just a start.  We are working away on the next generation in ClearOS 6.0.
