Linux is being used by an ISP in Pakistan—Mr. Rehman tells us why.
Low-Cost Access Server with Linux and Rocketport

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.

Conclusions

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.

Resourses

Rafeeq ur Rehman (rehman@pol.com.pk) 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.

Fabric-Based Computing Enables Optimized Hyperscale Data Centers

Today’s modular x86 servers are compute-centric, designed as a least common denominator to support a wide range of IT workloads. Those generic, virtualized IT workloads have much different resource optimization requirements than hyperscale and cloud applications. They have resulted in a “one size fits all” enterprise IT architecture that is not optimized for a specific set of IT workloads, and especially not emerging hyperscale workloads, such as web applications, big data, and object storage. In this report, you will learn how shifting the focus from traditional compute-centric IT architectures to an innovative disaggregated fabric-based architecture can optimize and scale your data center.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6

Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.
