Creating an initrd image

Post date: April 15, 2005, 23:04 Category: System Views: 3295 Comments
Tutorial quote: When I started booting a box with multiple SCSI adapters, I wanted to keep the device ordering sane. I find it’s best when the boot ordering matches the order in which Linux initializes the drivers for each controller. One effective way to handle this under Debian GNU/Linux with one of the stock kernels is to create a custom initrd image.

Creating a Wiki with kwiki

Post date: December 17, 2005, 22:12 Category: Software Views: 2722 Comments
Tutorial quote: Wikis are simple interactive websites which are extremely easy to use for storing easily updated text content. Using a Wiki you can easily create a lot of content with hyperlinks between them. Debian has packaged several different Wiki systems and here we'll look at installing just one of them: KWiki.

Wikis have become familiar to many people thanks to the popularity of large sites such as Wikipedia and can be very useful for creating collaborative websites.

Whilst there are many Wiki packages included in the Debian GNU/Linux distribution I've always had a soft spot for KWiki due to its simplicity, Perl nature, and low requirements.

Installing the software under Debian is very simple and we will show how to setup a new installation using the Debian Apache2 webserver package.

CLI Magic: OpenSSH + Bash

Post date: January 25, 2006, 20:01 Category: Network Views: 2974 Comments
Tutorial quote: As a system administrator, I have used OpenSSH's piping abilities more times than I can remember. The typical ssh call gets me access to systems for administration with a proven identity, but ssh is capable of so much more. In combination with bash's subshell invocation, OpenSSH can distribute the heavy work, reduce trace interference on a system under test, and make other "impossible" tasks possible. I've even used it to make Microsoft Windows remote administration easier.

In the examples below, I have tried to avoid GNU-specific idioms for tools which have non-GNU counterparts. This practice improves portability of shell scripts in heterogeneous environments.

Application optimization with compilers for Linux on POWER

Post date: May 23, 2005, 16:05 Category: Optimizing Views: 2763 Comments
Tutorial quote: The Linux on POWER platform offers more than one option to produce binary C/C++ code. In addition to supporting both 32- and 64-bit runtime environments simultaneously, Linux on POWER has two compiler collections. The GNU Compiler Collection, or GCC, is consistent with other Linux implementations with specific exceptions for the POWER architecture. GCC is the leading compiler for portability but also features a number of performance enhancements for optimizing code. The IBM XL C/C++ compiler for Linux on POWER is derived from the high performance compiler for AIX but uses the GNU linker and assembler to create ELF objects that are fully compatible with objects produced by GCC. This document provides side-by-side comparisons of how these two compilers are controlled, overviews of what the compilers are capable of, in terms of optimization, and tips for writing code that is more easily optimized with either of these compilers.

Xubuntu 7.04(Feisty Fawn) Screenshots Tour

Post date: June 11, 2007, 23:06 Category: Software Views: 3555 Comments
Tutorial quote: Xubuntu is a complete GNU/Linux based operating system with an Ubuntu base. It is lighter on system requirements and tends to be more efficient than Ubuntu with GNOME or KDE, since it uses the Xfce Desktop environment, which makes it ideal for old or low-end machines, thin-client networks, or for those who would like to get more performance out of their hardware.

The Perfect Desktop - Linux Mint Debian 201009

Post date: November 4, 2010, 12:11 Category: Desktop Views: 3414 Comments
Tutorial quote: This tutorial shows how you can set up a Linux Mint Debian 201009 desktop that is a full-fledged replacement for a Windows desktop, i.e. that has all the software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge. While the "normal" Linux Mint editions are based on Ubuntu, Linux Mint Debian 201009 is a Linux distribution based on Debian Squeeze (testing); its aim is to look identical to the main edition and to provide the same functionality while using Debian as a base.

Avoiding greedy webclients with mod_bwshare

Post date: November 8, 2006, 04:11 Category: Network Views: 2949 Comments
Tutorial quote: If you're running a popular website you'll most likely notice that some clients are less well-behaved than others. Greedy clients can do anything from make numerous requests, to attempting to spider your entire site. One simple way of preventing these clients from slowing down your server is with the mod_bwshare module for Apache2.

Unfortunately mod_bwshare is not yet packaged for Debian GNU/Linux however installing it from the source code is very straightforward.

How to suspend and hibernate a laptop under Linux

Post date: June 7, 2006, 20:06 Category: Hardware Views: 4768 Comments
Tutorial quote: Many people prefer working with laptops instead of desktops for the flexibility they offer. Some of them would also like to switch to a free and open source operating system like GNU/Linux and have their laptop do all the things that proprietary OSes offer, such as suspending their laptops. Several distributions try to make this work out of the box, but knowing what's under the hood always comes in handy, particularly when something goes wrong and needs fixing. Let's take a look at how to suspend and hibernate your laptop under Linux.
