Linux in Government: How to Misunderstand the Enterprise Linux Desktop
If you are considering deploying open-source software in your organization, this article aims to help you draw appropriate distinctions for your business case. We address economic issues, issues of security and administration and the availability of applications. We also discuss myths and perceptions of the dominant operating systems in the market today.
GNU/Linux and open-source software have matured and attained significant popularity within the enterprise space. GNU/Linux already has made a showing of dominance based on empirical indicators. For example, the Netcraft Web Server Surveys shows the Apache server as having an installed share of 67% to 71%. Apache has become the default Web server for Linux. The Linux desktop also receives consideration for enterprise deployment. Anchored by cross-platform productivity suites, such as OpenOffice.org, StarOffice and the Mozilla FireFox browser, Linux has gained acceptance in numerous heterogeneous environments.
One measure of enterprise acceptance achieved by Linux is its place among the elite operating systems produced by IBM, HP, Sun, SGI, Microsoft and Sony. In addition, two Linux enterprise distributions recently achieved the coveted status of Common Criteria Certification. This certification offers governments a high level of confidence in using Linux (see Table 1).
What is Common Criteria? Certification in this area provides standards for security for mission-critical software. Common Criteria Certification provides a seal of approval recognized by government agencies and enterprise IT professionals. Countries that recognize the Common Criteria include the United States, Canada, the United Kingdom, Australia, New Zealand, Germany, France and Japan.
In January 2004, Novell SuSE Linux Enterprise Server 8 earned the EAL 3 certification. Atsec Information Security GmbH, along with IBM, assisted Novell SuSE with the certification process. In May 2004, Oracle helped Red Hat achieve its Common Criteria certification. Version 3 of Red Hat Enterprise Linux was certified to meet EAL 2 of the Common Criteria Certification.
Having attained this certification, Red Hat and Oracle and Novell SuSE can be deployed in government operations and in the Department of Defense. It also means they can deploy into security-sensitive organizations, such as federally insured banks and other government and government-regulated agencies. State and local government units with Federal Assistance programs also can deploy Red Hat and Novell SuSE Enterprise distributions.
Table 1, below, lists all operating systems that have been evaluated, as taken from the complete and official list of all evaluated software products. As you can see, Linux shares space with some prestigious software.
On July 1, 2004, the Executive Office of the President of the United States issued a memorandum for Senior Procurement Executives and Chief Information Officers. The memorandum emphasizes the President's previous memorandum titled "Maximizing Use of SmartBuy and Avoiding Duplication of Agency Activities." In this latest memorandum, OMB 04-16, the President issued the following ground-breaking statements:
This reminder applies to acquisitions of all software, whether it is proprietary or Open Source Software. Open Source Software's source code is widely available so it may be used, copied, modified, and redistributed. It is licensed with certain common restrictions, which generally differ from proprietary software. Frequently, the licenses require users who distribute Open Source Software, whether in its original form or as modified, to make the source code widely available. Subsequent licenses usually include the terms of the original license, thereby requiring wide availability. These differences in licensing may affect the use, the security, and the total cost of ownership of the software and must be considered when an agency is planning a software acquisition.
This is merely one example of the changes under way in procurement policies and habits across federal, state and local government agencies nationwide. Despite great odds and powerful opposition to changes in the status quo, open-source software has established a place at the conference table, where it will stay and survive on its merits.
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
