Schwarzenegger Endorses ClearOS!

Posted by on in ClearFoundation

Its always open season on the execs on April 1st! The ClearCenter Team conspired to trick our fearless leader Michael Proper with an endorsement by Arnold Schwarzenegger! With a bit of creative programming and some bold faced plagiarism, we mocked up a fully functional copy of the Sacramento Bee web site in our internal servers and spiced up a recent Arnold quote with a raving endorsement of ClearOS! We even included a few juicy comments by celebs and a photo caption!

We had him until he hit the April fool's date at the end of the article. Good for a laugh!

Happy April Fool's Day from ClearCenter!

Princess and the ClearOS Module - Part 1 of 4

Posted by on in ClearFoundation

Ever have the feeling "ClearOS is good piece of software...maybe even great. I just wish it had __________".  All around the world, in 22 different languages, I'm sure the ending to that sentence has been completed with an equally broad range of functions - from running a media server used for streaming music and movies to your TV to cooking up a corn-beef on rye. For those that are interested, the former is coming soon while the latter...well, maybe never and definitely not from me...I'm not a big fan of the salted beef.

At any rate, I had this exact feeling over the weekend when I started wondering how I managed to fill up a 140 GB hard disk drive on my ClearOS server at home.  Seems the combination of having two girls under the age of 5 has a rather exponential effect of disk space usage with:

a) the number of digital photos of the two of them growing up (Doh! I had to buy the 15.1 megapixel model)

b) the astounding number of princess movies one can downlo....ahem, collect

But I digress, and I'm only going to get myself into copyright trouble. I know about Bash's "du" using a wack of parameters and possibly having to resort to piping the output to yet more cryptic bash commands...


l7-filter Finds a New Home with ClearFoundation

Posted by on in ClearFoundation

l7-filter -- the Application Layer Packet Classifier for Linux -- Finds a New Home with ClearFoundation

The L7-filter software is a vibrant open source project.  The software is an application layer packet classifier that can differentiate types of network traffic by protocol; for example it can identify bittorrent, IRC, SIP and many other types of traffic.   In turn, these classifiers can be used to block or shape traffic according to a defined network policy. L7-filter is a very reputable project that has been integrated with ClearOS for some time.

ClearFoundation has been handed the reins and will take on maintenance for the project!  That means the capable ClearFoundation development team will be maintaining the code base, improving features, co-ordinating with other developers and updating software as needed. Documentation, bug tracking, testing, protocol filter definitions, and user feedback round out other maintenance tasks.  With the already thousands strong community and an open source not-for-profit foundation supporting the initiative, maintaining l7-filter is a good fit.

ClearOS Development Meetings - Kickoff Event

Posted by on in ClearFoundation

The Development Team is organizing regular online meetings to discuss ClearOS milestones and roadmap topics.   The meetings are open to everyone and are a chance for developers, beta testers, translators, neoentomologists, documentation gurus and anyone interested in ClearOS development to openly discuss the state of the platform.

The first part of all meetings are high level discussions on ClearOS. This is a chance for the non-geeks to participate in important policy decisions. As the meeting progresses, discussion will start to delve deeper into technical topics. You have been warned!

The kick-off meeting is going to held Friday, February 19 2010 @ 12:30 p.m. Eastern.  We'll post an update early next week on how to join the online meeting (we are evaluating Dimdim right now).   You find the proposed agenda here.


ClearFoundation Issues Patch For Security Issue With Samba

Posted by on in ClearFoundation

ClearFoundation has issued a patch to Samba for ClearOS.  Samba provides much of the file service and Windows networking components for ClearOS. Earlier today the Samba team issued a statement indicating that all versions of Samba should have a key configuration parameter updated.  The security risk is not high because the file access requires both a secure connection (LAN or VPN, not the Internet) and valid username/password into Samba section of the ClearOS system.  Data on the system is still protected with standard system file permissions.

This patch will take effect on all ClearOS servers which are receiving software updates at their next update cycle.


ClearCenter Gives To Mercy Corps

Posted by on in ClearFoundation

One of our customers is Mercy Corps in Portland, OR.  They are a global relief agency helping those in need around the world.  During a recent conversation, they described their first hand knowledge of the devastation in Haiti.  They are on the ground delivering needed supplies and resources.

Haiti's capital city is said to be "flattened," and officials say the number of dead may top 100,000.

Mercy Corps is deploying a team of relief workers to the island to help meet survivors' most urgent needs -- like shelter, food and clean water. They've responded to dozens of disasters like this in the past, such as earthquakes in Peru in 2007, in Pakistan and China in 2008, and in Padang, Indonesia last year.

ClearCenter began a donation page to Mercy Corps to help with funds for their efforts in Haiti.  Please check out the ClearCenter Gives page for more info -- -- and please consider making a gift on behalf of their campaign.

Thank you!  The ClearCenter Team

The Small Business Server Replacement is Clear(OS)

Posted by on in ClearFoundation

 Microsoft still has a stranglehold on the desktop and servers for small business. While wheels are in motion for the former, the answer to the latter may already be here.

When it comes to the Internet, Linux is a big win.

Mail and web servers, databases, computational clusters and supercomputers all belong to the domain of free software. When it comes to embedded devices, Linux is also king of the roost.

There are two main areas where Linux has still not broken through, however - the desktop and servers for small business. Many small to medium enterprises are already “Microsoft shops” because the desktops run Windows. To break in, Linux needs to slot into these environments without causing a fuss.

Certainly the cloud is offering one solution to this problem, but not all companies are willing to put their sensitive data on-line and in the hands of another. So, a market for local servers to perform these functions is still alive and well.

The requirements

Part of the reason that Microsoft Small Business Server (SBS) is attractive is that it includes many core features required by a company, out of the box. Important services like central authentication, email, file and print sharing and web. Perhaps most important of all is calendaring. It’s something which businesses simply cannot survive without and has been a thorn in the side of Linux based alternatives for a long time.

Here’s a quick glance at some of the main features included with SBS:

  • Centralized Authentication (LDAP)
  • Primary Domain Controller (Samba)
  • File and Print Services (Samba and CUPS)
  • Mail (SMTP, POP, IMAP, Webmail)
  • Calendaring (Kolab groupware)
  • Webserver (Apache)
  • Firewall plus intrusion protection (iptables, Snort)
  • Antimalware (Clam Antivirus, Antiphishing, Antispyware)
  • Antispam (Spamassassin)
  • Database (MySQL)
  • Virtual Private Network (IPSec, OpenVPN, PPTP)
  • Web Proxy (Squid)

The complexity of these individual components is hidden behind the web based management interface, where users can simply turn on and off these modules as required.

While users are encouraged to administer the system via the provided management interface, it is also designed to be extensible. The back end is not hidden away, but offered up in plain sight for admins to get right in and change things if they want to. Various how-tos provide details on how to perform extra functions, such as enabling shell access for users.

ClearOS supports external modules, that is extra services outside of those included by default. This is part of the design goal of the operating system which will hopefully foster collaboration and increase its range of useful features. It is possible to replace the default groupware server with a more sophisticated one or even create new custom modules, such is the flexibility.

The included Kolab groupware server is reasonable, however it appears that a connector for Outlook must be purchased separately, such as that from Toltec or KONSEC. A feature rich, but rather unattractive, web client is also included via Horde. Linux users can have native support through KDE’s Kontact application, or Mozilla’s Thunderbird and the Sync Kolab addon.

The installer is straight forward and supports both hardware and software RAID. During installation the user is able to select a number of services to include, however these can also be configured at a later stage via the web management interface.

The web-based management interface is very intuitive and easy to follow. Server features are broken up into sections, such as Directory, Network, System and Gateway, where admins can configure various components thereof. Everything, from adding a user to configuring an IPSec VPN is a matter of a few simple steps. Within 5 minutes an administrator can have a fully functional Windows domain server, with all the bells and whistles. Pretty neat, eh?

Also built into the interface are various reports, such as the state of system resources, traffic usage and analysis, mail and web server statistics, as well as good old system logs.

ClearOS Web Management Interface

It would be good to see some improvements in the interface, to provide greater feedback. While installing packages for example, the interface appears to be doing nothing, while it is in fact downloading or installing. Reading the install log makes sense, but only if you know what you’re looking for. It would be great to see a simple feedback method in addition to the log. A rotating orange swirl while performing the task would suffice, turning green upon completion. It’s also a shame that there is no 64 bit version, however this might come at a later date if warranted.

Despite this, ClearOS is truly a decent replacement for Windows SBS. It has all the features yet is simple to manage and has the full power of Linux and free software right behind it.

ClearFoundation Infrastructure and Developer Tools

Posted by on in ClearFoundation

A late happy new year to everyone!

We are making progress on building out the necessary infrastructure to develop ClearOS.   Some of the infrastructure is new, while other parts are migrating over from the old ClarkConnect system.

On January 14 2010,  the Bug Tracker  was added to the web site.  If you suspect that you have found a bug, we really do appreciate it when you take the time and effort to report them.  Without the feedback, it makes it difficult to make future releases better and more bug free!

In the next week or so, the source code repositories will be coming online.  In addition, we have three other pieces of infrastructure under active development:

  • A feature/wishlist system
  • A new translation system that will make life easier for translators
  • A new build system that will pave the way for 64-bit support

We'll post a message when these tools are available.

A CLEAR New OS Concept.

First of all I guess I should do the obligatory disclosure according to the American FTC which is just a guide but has lawful penalties (how do they figure that one out?) I received this product for free from the Clear Foundation. In return I am going to do a review of their product.

That being said they are giving their product away for free to everyone. In typical Open Source business model it is the service they are charging for. The product? The new release of the beta version of their latest ClearOS(5.1). I found out about this when their marketing manager Aaron contacted me here on ITtoolbox and basically just said check out what we did and tell me what you think.

Well since it was no skin off of my nose to download their ISO image and whack it into a VirtualBox session I did so. While I was trying to download it I hopped over to their website and had a peek and poke around (aah the old basic days, sigh). What I saw intrigued me to say the least. I was expecting just another fork of another Linux distribution. You know the standard Ubuntu, Debian, SUSE, RedHat type of thing. One thing was evident was that these people were definitely thinking out of the box.
