How To Save Traffic With Lighttpd's mod_compress (Debian Squeeze)

Post date: April 7, 2011, 10:04 Category: Miscellaneous Views: 2849 Comments
Tutorial quote: In this tutorial I will describe how to configure mod_compress on a Lighttpd web server (on Debian Squeeze). mod_compress allows Lighttpd to compress files and deliver them to clients (e.g. browsers) that can handle compressed content which most modern browsers do. With mod_compress, you can compress HTML, CSS, Javascript, text or XML files to approx. 20 - 30% of their original sizes, thus saving you server traffic and making your modem users happier.

Virtual Users & Domains With Postfix, MySQL & SquirrelMail (Mandriva 2008.1)

Post date: April 15, 2008, 11:04 Category: Installing Views: 3982 Comments
Tutorial quote: This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I will also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.

Choosing an I/O Scheduler for Red Hat Enterprise Linux 4

Post date: July 18, 2005, 22:07 Category: Benchmarks Views: 8709 Comments
Tutorial quote: The Linux kernel, the core of the operating system, is responsible for controlling disk access by using kernel I/O scheduling. Red Hat Enterprise Linux 3 with a 2.4 kernel base uses a single, robust, general purpose I/O elevator. The 2.4 I/O scheduler has a reasonable number of tuning options by controlling the amount of time a request remains in an I/O queue before being serviced using the elvtune command. While Red Hat Enterprise Linux 3 offers most workloads excellent performance, it does not always provide the best I/O characteristics for the wide range of applications in use by Linux users these days. The I/O schedulers provided in Red Hat Enterprise Linux 4, embedded in the 2.6 kernel, have advanced the I/O capabilities of Linux significantly. With Red Hat Enterprise Linux 4, applications can now optimize the kernel I/O at boot time, by selecting one of four different I/O schedulers.

Avoiding slow package updates with package diffs

Post date: September 18, 2006, 13:09 Category: Network Views: 3857 Comments
Tutorial quote: If you're using the unstable or testing distribution of Debian GNU/Linux you will almost certainly have noticed that apt-get uses daily-diffs for its package updates. In many common situtations this is more bandwidth efficient, however it isn't always appropriate.

apt-get is a standard command which is used by many Debian users to manage package installation, and upgrades. (Although there are also other package managers such as synaptic, or aptitude.)
Mepis

Mepis + apt = Working On Easy Street

Post date: April 13, 2005, 19:04 Category: System Views: 7037 Comments
Tutorial quote: My reasoning for combining the traditional Debian apt command with Mepis was speed and efficiency. Also, in the fine tradition of open source, I could choose to use the command line instead of the Kpackage or Mepis System Center package management screen. This is a good way to learn about Debian systems that builds confidence for new users right off the bat.

Let's see how apt works with Mepis.

How To Save Traffic With mod_deflate On Lighttpd 1.4 (Debian Etch)

Post date: August 15, 2007, 22:08 Category: Installing Views: 3536 Comments
Tutorial quote: In this tutorial I will describe how to install and configure mod_deflate on a lighttpd 1.4 web server on Debian Etch. mod_deflate is included by default in lighttpd 1.5, but not in 1.4 where mod_compress is used instead. The advantage of mod_deflate over mod_compress is that it can compress static and dynamic files (such as PHP files), whereas mod_compress can compress static files only. The lighttpd version coming with Debian Etch is 1.4.13, so we have to patch it to support mod_deflate. mod_deflate allows lighttpd to compress files and deliver them to clients (e.g. browsers) that can handle compressed content which most modern browsers do. With mod_deflate, you can compress HTML, text or XML files to approx. 20 - 30% of their original sizes, thus saving you server traffic and making your modem users happier.
