If you are new to Linux, chances are you will meet a stupid person perhaps in a forum or chat room that can trick you into using commands that will harm your files or even your entire operating system. To avoid this dangerous scenario from happening, I have here a list of deadly Linux commands that you should avoid.

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?

If you work on Linux you?ll know that the command line is the way to go (in some cases at least). If you are in GUI mode than you can access the command line via the Terminal. Here are some applications/utilities that will transform your command line experience.

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.

Networking is a must-have on all levels of computing. Be it home or corporate, networking is the one aspect of computing that is, without a shadow of a doubt, a deal breaker. And with some help, the Linux operating system can be the king of networking, in both ease of use and security. But that doesn?t mean the average (and sometimes even the above-average) user can?t use some help. These tips should help make Linux networking go a little more smoothly.

A good way to see how your Web applications and server will behave under high load is by testing them with a simulated load. We tested several free software tools that do such testing to see which work best for what kinds of sites. If you leave out the load-testing packages that are no longer maintained, non-free, or fail the installation process in some obscure way, you are left with five candidates: curl-loader, httperf, Siege, Tsung, and Apache JMeter.

When it comes to file systems, Linux? is the Swiss Army knife of operating systems. Linux supports a large number of file systems, from journaling to clustering to cryptographic. Linux is a wonderful platform for using standard and more exotic file systems and also for developing file systems. This article explores the virtual file system (VFS)?sometimes called the virtual filesystem switch?in the Linux kernel and then reviews some of the major structures that tie file systems together.
The OpenBIOS project provides you with most free and open source Open Firmware implementations available. Here you find several implementations of IEEE 1275-1994 (Referred to as Open Firmware) compliant firmware. Among its features, Open Firmware provides an instruction set independent device interface. This can be used to boot the operating system from expansion cards without native initialization code. It is Open Firmware’s goal to work on all common platforms, like x86, AMD64, PowerPC, ARM and Mips. With its flexible and modular design, Open Firmware targets servers, workstations and embedded systems, where a sane and unified firmware is a crucial design goal and reduces porting efforts noticably.

Back in the good old days, there was an operating system that didn’t seem to think NAME and name were different. The result was that sometimes when you transfered files from a floppy disk (remember them?) created on that Dumb Old System, you would clutter your directory with uppercase filenames. As us UNIX old-timers learned a nifty trick to get directory names to sort before filenames in the output of the ls command (namely, start directory names with an uppercase letter), having filenames with uppercase letters was irritating.

This article describes how to build a Local Area Network (LAN) consisting of two or more computers running the Red Hat Linux operating system. The article begins with the basics: an overview of the TCP/IP (Transmission Control Protocol/Internet protocol) suite, and an explanation of assigning IP addresses in a LAN. Then the article covers the LAN hardware and configuration using a tool called LinuxConf in the Red Hat Linux operating system environment. Lastly, the article walks you through the critical steps of testing and troubleshooting your LAN.

Want to get an idea of what speed advantage adding an expensive hardware RAID card to your new server is likely to give you? You can benchmark the performance difference between running a RAID using the Linux kernel software RAID and a hardware RAID card. My own tests of the two alternatives yielded some interesting results.
