Linux Means Business: A Case Study of Pakistan On-Line
When you plan a very small ISP site or corporate network with a small number of dial-in users, it may be useful to deploy Linux as a remote access server. This saves a lot of money. We are using Linux with the Comtrol Rocketport multiport PCI adapters for this purpose. One Linux system can support up to four adapters, each with 32 high-speed serial ports. Thus, in total you can have 128 ports available in a single Pentium-based computer with good throughput. Since Rocketport cards have on-board intelligent processors, these do not pose much load on the computer. Now, just by making some changes in the login procedure, you can configure many things. For example, you can set the number of simultaneous logins you will allow for a single login name.
Linux is a very useful and stable operating system for ISP services. It provides a cost-effective, user-friendly, easy-to-configure environment. The number of utilities available for ISP operation and support is excellent. The biggest advantage is that it can be used in almost any environment and provides an edge over your competitors.
Rafeeq ur Rehman (email@example.com) received bachelor's and master's degrees in Electrical and Computer Engineering, respectively, from the University of Engineering and Technology, Lahore, Pakistan. His main areas of interest are computer networks and distributed computing. He has been using Linux since kernel version 0.0.99.
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
