Let’s face it, most technical and computer books are boring, and reading the texts cover-to-cover is nothing less than a slog. However, there are some exceptions, including a number of books apropos for system administrators. In fact, there are three books I highly recommend and are mandatory reading for my staff.

Do you have a linux server without a keyboard or monitor? Need to administer the server on-site but don’t want to lug over a monitor and keyboard (or kvm)? Then setup the server to output the console to a serial port and use screen/minicom (Hyperterminal or putty in Windows) to console into the server over a serial cable.

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.

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.

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.

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.
