Feed Your Virus Worries to a Clam

Post date: April 14, 2005, 13:04 Category: Network Views: 3486 Comments
Tutorial quote: Last week, we looked at how to set up SpamAssassin with Postfix, as part of a lean, mean, spam-killing gateway machine. This week we'll add an anti-virus scanner to our bubbling brew.

Linux stateful firewall design

Post date: April 12, 2005, 17:04 Category: Network Views: 3111 Comments
Tutorial quote: This tutorial shows you how to use netfilter to set up a powerful Linux stateful firewall. All you need is an existing Linux system that's currently using a Linux 2.4.x or 2.6.x kernel. A laptop, workstation, router or server with at a Linux 2.4.x or 2.6.x kernel will do. You should be reasonably familiar with standard network terminology like IP addresses, source and destination port numbers, TCP, UDP and ICMP, etc. By the end of the tutorial, you'll understand how Linux stateful firewalls are put together and you'll have several example configurations to use in your own projects.

Build Your Own Video Community With Lighttpd And FlowPlayer (Debian Etch)

Post date: August 19, 2007, 23:08 Category: Miscellaneous Views: 3534 Comments
Tutorial quote: This article shows how you can build your own video community using lighttpd with its mod_flv_streaming module (for streaming .flv videos, the format used by most major video communities such as YouTube) and its mod_secdownload module (for preventing hotlinking of the videos). I will use FlowPlayer as the video player, a free Flash video player with support for lighttpd's mod_flv_streaming module. I will also show how you can encode videos (.mp4 .mov .mpg .3gp .mpeg .wmv .avi) to the FLV format supported by Adobe Flash.

Failover Firewalls with OpenBSD and CARP

Post date: April 28, 2005, 02:04 Category: Network Views: 8876 Comments
Tutorial quote: Firewalls are a required component in commercial and residential computer networks. For many installations, the firewall is a single point of failure between client systems and external resources. It can also become a liability when hardware or applications fail, leaving potential customers unable to reach your servers. A properly designed and executed failover configuration for your primary firewall will address many of these concerns. This article introduces a proven method for installing redundant stateful firewalls using native OpenBSD features.

LCD displays easy to use and easy to build

Post date: May 24, 2005, 18:05 Category: Hardware Views: 4209 Comments
Tutorial quote: This article presents now the "basic" model: LCD display and 2 buttons; simple and easy to build for everybody.

Lcdproc used to be at the very beginning a program to display some statistics (cpu load, uptime, time, ...) on an external LCD display. Over time it has however evolved into a much more generic solution. Today the lcdproc package contains LCDd, a generic server and LCD driver, plus many clients. One of those clients is still the actual executable called lcdproc which still shows server statistics however there are also others. This client server architecture has the big advantage that you do not need to write your client in a specific language. You just need to use the simple ascii protocol between client and server.

How To Look Like A UNIX Guru

Post date: October 30, 2006, 02:10 Category: Miscellaneous Views: 6525 Comments
Tutorial quote: UNIX is an extremely popular platform for deploying server software partly because of its security and stability, but also because it has a rich set of command line and scripting tools. Programmers use these tools for manipulating the file system, processing log files, and generally automating as much as possible.

If you want to be a serious server developer, you will need to have a certain facility with a number of UNIX tools; about 15. You will start to see similarities among them, particularly regular expressions, and soon you will feel very comfortable. Combining the simple commands, you can build very powerful tools very quickly--much faster than you could build the equivalent functionality in C or Java, for example.

This lecture takes you through the basic commands and then shows you how to combine them in simple patterns or idioms to provide sophisticated functionality like histogramming. This lecture assumes you know what a shell is and that you have some basic familiarity with UNIX.

How To Set Up A Facebook RSS Feed Reader Application For Your Blog

Post date: September 2, 2007, 23:09 Category: Programming Views: 6613 Comments
Tutorial quote: This guide shows how you can build an RSS feed reader application for the social network Facebook that will display your blog's/web site's RSS feed on the profile pages of Facebook users (that have installed the RSS feed reader application). Each item of the RSS feed will have a Share button so that people can share the story with their friends, and the application will have an Invite link so that people can invite up to ten friends at once to also install this feed reader application. I will use PHP5 to build the RSS feed reader application. To parse the RSS feed and generate HTML from it, I will use Magpie RSS.
