It is critical to understand how an application is interacting with the operating system, CPU, and memory system to understand its performance. This chapter will help you understand where the bottleneck in your system is occuring, and how to fix it.

System encryption on Debian Etch

Post date: August 16, 2006, 16:08 Category: Security Views: 5737 Comments
Tutorial quote: In this article I will describe how to setup a nearly complete encrypted system using Debian Etch and cryptsetup with LUKS. The goal is: encrypt all partitions except /boot. The user should enter a password at boot time or provide a keyfile on an USB device to decrypt the root partition. Keyfiles for additional partitions are located on the root, so the user does not need to enter a password for every partition.

Good-looking fonts in X Windows

Post date: April 23, 2005, 09:04 Category: Desktop Views: 3119 Comments
Tutorial quote: What makes the difference betweek "ugly" and "beautiful" fonts? Several things.

One of them is anti-aliasing (or AA in short). It's the technique which adds gray pixels in various shades around the edges of black text and thus blurs the jagged and pixelated edges. It works with other colors, too.

Another thing is having good quality fonts to start with. Font which are ugly by nature or don't scale well to various sizes are not much nicer when anti-aliased. See what kinds of fonts are out there by browsing through the Font HOWTO (not the same as the FDU HOWTO above).

Finally, there's the issue of readability which applies to you directly. How well does the end-product look anyhow? Do you really need anti-aliasing for an 8 pixel text? And other similar questions, which you'll learn how to answer according to your own preferences.

Monitoring Multiple Systems With munin (Debian Etch)

Post date: March 6, 2008, 13:03 Category: Miscellaneous Views: 6429 Comments
Tutorial quote: In this article I will describe how you can monitor multiple systems with munin. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration. I will install the munin client on all systems that are to be monitored (including the munin server itself); the munin clients will then report to the munin server.

SpamAssassin, ClamAV and Procmail Howto

Post date: April 16, 2005, 00:04 Category: Network Views: 3719 Comments
Tutorial quote: This document describes how to install SpamAssassin (for filtering SPAM) and ClamAV (for filtering viruses, trojans, worms, etc.) and how to invoke them by using procmail recipes. It is suitable for scenarios where Sendmail or Postfix deliver emails to local users. It should work (maybe with slight changes concerning paths etc.) on all *nix operating systems. I tested it on Debian Woody so far.

In the end you will have a system where Sendmail or Postfix deliver emails to a local user; the emails are passed to procmail which invokes SpamAssassin and ClamAV in order to filter the emails before they arrive in the user's inbox. However, the installation of Sendmail and Postfix are not covered in this document.

This howto is meant as a practical guide.

Hacking OpenSUSE

Post date: December 3, 2005, 17:12 Category: System Views: 7522 Comments
Tutorial quote: There's more to SUSE Linux than simply installing it and going to work. To get the most from the operating system, you'll probably want to do some post-install fine tuning. This article by Jem Matzan explains how to: add download sources to YaST; install the Mozilla Thunderbird email client; add support for Java, Flash, Acrobat, Windows Media, MP3s, and RealMedia; play DVDs -- and more. It serves as a useful supplement to Steven J. Rosen's excellent how-to, "Installing SUSE Linux 10 on a Laptop," recently published here on DesktopLinux.com. Enjoy . . . !
