Eveyone knows about netfilter/iptables, a powerful firewall framework and command line tool that is part of every Linux distribution. Unfortunately, managing a security policy with it remains a non-trivial task for several reasons. Partially this is because of the complex syntax of the command line interface and the vast amount of available options and parameters. Another reason is that the administrator has to understand the internal path of the packet inside the Linux kernel and its interaction with different parts of netfilter in order to build rules correctly. This is not a specific problem of iptables though, other popular Open Source firewall platforms, such as OpenBSD PF, ipfilter and ipfw present similar challenges.

Fernando Apesteguia concludes: “When a distribution is packaged and delivered to clients, it is designed to be fully compatible with most of the computers available in the market. This is a very heterogeneous set of hardware (hard disks, video cards, network cards, etc.). So distribution vendors like Red Hat, SuSe, Mandriva and the rest of them choose some conservative configuration options to assure a successful installation.”

Cluster means different things to different people. In the context of this article, cluster is best defined as scale-out — scale-out clusters generally have a lot of the same type of components like Web farms, render farms, and high performance computing (HPC) systems. Administrators will tell you that with scale-out clusters any change, no matter how small, must be repeated up to hundreds of thousands of times; the laziest of admins have mastered techniques of scale-out management so that regardless of the number of nodes, the effort is the same. In this article, the authors peer into the minds of the laziest Linux® admins on Earth and divulge their secrets.

Programming language tutorials either appeal or do not appeal based on any number of personal factors. Some developers prefer simple lessons that move learning forward in stages. Others like the facts to be laid out in familiar terms with a minimum of hand-holding. Each of the following sites presents its own approach to mastering Python, which you may or may not find useful for your learning path. These represent just a fraction of the available online Python tutorial resources.

This document is intended to help Linux and Internet users who are learning by doing. While this is a great way to acquire specific skills, sometimes it leaves peculiar gaps in one’s knowledge of the basics — gaps which can make it hard to think creatively or troubleshoot effectively, from lack of a good mental model of what is really going on.
I’ll try to describe in clear, simple language how it all works. The presentation will be tuned for people using Unix or Linux on PC-class machines. Nevertheless, I’ll usually refer simply to ‘Unix’ here, as most of what I will describe is constant across different machines and across Unix variants.

Particularly for hard disks, the tool in charge is smartctl from the package smartmontools. IDE disks (if they’re not of the age of dinosaurs) have an integrated self-testing tool called SMART which means “Self-Monitoring, Analysis and Reporting Technology”. Modern SCSI disks have it too if they’re SCSI 3 or newer. It happens that inside the disk chipset there are routines to check parameters of disk health: spin-up time, number of read failures, temperature, life elapsed… And all of those parameters are not only registered by the disk chipset, but they have designated security limits and both parameters and limits can be checked by software who access the disk using the appropriate I/O instructions.

There’s a good chance the most powerful chip inside your PC, in raw computational terms, is on your graphics card. So, how did graphics get so powerful, what are graphics cards good for right now and how on earth do you choose from the baffling array of 3D chipsets on offer?

As with every other component, motherboards have come a long way from the original IBM PC of 1981. If you’re old enough to remember the first De Lorean DMC-12, perhaps the original PC XT mobo still casts some dark shadow over your memory? At the time there were certainly wonders to behold; these days, they simply look a mess with integration the last thing on the designers mind and all the IO having to be decidedly off-board.
