Caldera OpenLinux (COL) is a defunct Linux distribution. Caldera originally introduced it in 1997 based on the German LST Power Linux distribution, and then taken over and further developed by Caldera Systems (now SCO Group) since 1998. A successor to the Caldera Network Desktop put together by Caldera since 1995, OpenLinux was an early "business-oriented distribution" and foreshadowed the direction of developments that came to most other distributions and the Linux community generally.[citation needed]

During 1996, Caldera continued to be a valuable player, for example, on 23 May 1996, at the Linux Kongress in Berlin, Germany, Caldera announced its plans to obtain POSIX and FIPS certifications and the X/Open brand for UNIX 95 and XPG4 BASE 95 for the Linux operating system kernel and "Open Linux".[1]

In contrast to CND OpenLinux was based on LST Power Linux, a Slackware-derived distribution that had been maintained by Linux Support Team since 1993[2] and the first to come with a Linux 2.0 kernel.[3] In 1996 Linux Support Team grew into Stefan Probst's and Ralf Flaxa's company LST Software GmbH (with LST now standing for Linux System Technology[2]) in Erlangen, Germany. The OpenLinux development led them to become Caldera's German development center Caldera Deutschland GmbH since May 1997.[3][2]

On 23 July 1996, Caldera purchased Novell DOS and the remaining Digital Research assets from Novell in order to bundle a DOS with their version of Linux, which led to creating the OpenDOS distribution to help port DOS applications.[4][nb 1]

Caldera supported the Linux-port of StarOffice 3.1 with ca. 800.000 DM in order to offer the product with their forthcoming OpenLinux distribution in 1997.[5][6][7][8]

By 1997, when the OpenLinux distribution was first released, Caldera had taken on the form that it would be most remembered for. Caldera had switched over to the high end Linux product. The "business" Linux distribution became more rich with features with bundled proprietary software. However, it became less community oriented and was released less frequently than other Linuxes did.[citation needed] Other differences included automated configuration for administration tools, paid technical support staff, built-in consistent default GUI, and a range of supported applications.

Over the next[when?] five years, Caldera Systems offered additional commercial extensions to Linux. They licensed Sun's Wabi to allow people to run Windows applications under Linux. Additionally, they shipped with Linux versions of WordPerfect (from Novell and later Corel) and CorelDRAW. Since many of their customers used a dual boot setup and FIPS was unreliable, they shipped with PowerQuest's PartitionMagic to allow their customers to non-destructively repartition their hard disks.

In partnership with IBM they produced the first Linux distribution which was DB2 compatible. With the Oracle Corporation they became the target platform for the Linux port of the Oracle database.

Other ventures included starting the Blackdown Java project,[citation needed] and creating professional certification.

They also formed strong partnerships with SCO's value-added reseller market[when?] and started laying the groundwork for OEM sales of Unix-based vertical applications.

Caldera Systems offered three versions of OpenLinux:

  • OpenLinux Lite was a freely downloadable version.
  • OpenLinux Base was a USD 99 version with a few extensions.
  • OpenLinux Standard was USD 299 and was their fully featured product.

In addition to other people's applications, they created many Linux extensions to fill voids where no other commercial company was.

Caldera Systems initiated the development of a Linux alternative to Microsoft Exchange Server and Microsoft Outlook, resulting in the creation of Volution Messaging Server. This server provided functionalities such as calendaring and scheduling, shared busy/free information, SSL support for emails, and easy configuration.[9] Additionally, Caldera Deutschland pioneered the development of Lizard,[10] the first fully graphical installer for Linux, which debuted in November 1998. They were also credited[citation needed] with introducing browser-based Unix system administration and supporting projects like webmin, employing developer Jamie Cameron from 1999 to 2001.

Furthermore, Caldera Systems introduced Caldera Open Administration System (COAS), a comprehensive GUI system administration tool. COAS boasted a user-friendly interface, modular design for ease of use, and scalability. Its key features included portability via a platform repository, an open development model, flexible module licensing, support for multiple user interfaces (including batch processing, ncurses, Qt, and Java), a scripting interface (Python) for rapid prototyping, and backward compatibility, making it compatible with native files and friendly to users accustomed to command-line interfaces like "vi admin".

Caldera Systems created a full featured GUI system administration tool called Caldera Open Administration System (COAS).[when?] The tool was a unified, easy to use administration tool with a modular design. With its scalability and broad scope abilities, it featured:[11][12]

OpenLinux showed the Linux community what would be required to create a mainstream desktop OS out of the Linux kernel. In many ways the last ten years[when?] of desktop progress has been to successfully implement what Caldera was attempting to do with the tools they had available using open source software in place of the closed applications. Their technique for this was to utilize commercial software to fill in the largest gaps making their product a "value add" and thus they could charge for it. It made them the most commercial and at the same time it made them the most advanced distribution available.

The desktop company became Caldera International under the direction of Ransom Love.[dubious – discuss]

The focus for the desktop company became mainly marketing and business relationships. There were several reasons for this. The first was that Caldera had won a $280 million[13] lawsuit against Microsoft for DR-DOS and was flush with cash.[citation needed] Secondly, while the Caldera distribution was good, its primary advantages were the use of technologies not owned by Caldera and thus if Caldera were successful its success could (from a technical standpoint) be imitated, by Red Hat, SUSE, TurboLinux, etc. Third, for years Caldera had been competing directly with SCO Unix, but by 1997 Linux outperformed SCO in almost every respect.[citation needed]

Making the choice to switch from SCO to Caldera was not a "no-brainer" for companies because that also meant a switch of vendors and support organizations. Caldera's SCO acquisition was aimed at eliminating this problem. That is Caldera International's corporate direction became to combine SCO's distribution, marketing and VAR arm with LAMP, and use Project Monterey to develop a 64-bit strategy. What SCO offered was:[14]

  • A strong list of business clients.
  • Higher compatibility between SCO and Linux than any other Unix/Linux combination, mainly as a result of Caldera's long standing SCO focus that created products like ABI and thus resulted in ports of SCO code to Linux
  • A good back-office and database solution while Linux specialized in networking (LAMP) and client desktop, a very appealing combination in challenging Sun and Microsoft
  • A global infrastructure (presence in about 80 countries), Caldera was domestic
  • Thousands of business applications targeted to vertical markets
  • Some of the 3rd party components needed to get HP-UX, AIX, Solaris 3rd party Java applications ported to Linux

From a technical standpoint however Caldera OpenLinux really shone during the Ransom Love years. Their commercial bundling solution continued to work. They had a powerful low bug (by Linux standards) distribution that worked well on a wide range of hardware. They charged a great deal relative to other distributions and were able to generate a very strong profit. Red Hat pulled way ahead of them in terms of US sales and on the global sales front they trailed SUSE and TurboLinux as well, but financially due to the DR-DOS settlement they were the strongest of all the Linux distributions.[disputed (for: refuted by events – Red Hat survived in the Linux business, Caldera did not)  – discuss]

Further information: SCO-Linux controversies

In 2002, the Caldera International board of directors, including Ralph Yarro, named Darl McBride, formerly with Franklin-Covey, as CEO. The company was renamed The SCO Group. Ransom Love was reassigned to work exclusively on United Linux. After he completed this, he left the company to join Progeny Linux Systems which was aiming to create a professional Debian. He remained there in the capacity of a board member and advisor[17] until 30 April 2007 when Progeny ceased operations.

McBride began to focus on SCO's copyrights. One of McBride's first acts as CEO was to collect $600,000 in back licensing fees that were owed to Caldera International. He cleaned up various Linux-related licensing issues allowing for a new round of financing.[18] Soon thereafter he made strong accusations that Linux had infringed copyrights SCO held on Unix; they claimed to have purchased these copyrights from Novell. Novell denied selling them the Unix copyright, prompting them to sue for slander of title. SCO also initiated lawsuits against IBM and AutoZone, alleging copyright infringements through the use or distribution of Linux; none of these lawsuits have been resolved. SCO has created a division, SCOsource, that owns and licenses their intellectual property; a desktop license is $699.
