It describes how to build a custom kernel using the latest unmodified kernel sources from www.kernel.org (vanilla kernel) so that you are independent from the kernels supplied by your distribution.

Various ways of detecting rootkits in GNU/Linux
This is a detailed review of two scripts which are available for Linux and Unix alike which does a good job of detecting if your computer is infected by a rootkit.

Setting Up A PXE Install Server For Multiple Linux
This tutorial shows how to set up a PXE (short for preboot execution environment) install server with Ubuntu 6.10 (Edgy Eft). A PXE install server allows your client computers to boot and install a Linux distribution over the network, without the need of burning Linux iso images onto a CD/DVD, boot floppy images, etc. This is handy if your client computers don't have CD or floppy drives, or if you want to set up multiple computers at the same time (e.g. in a large enterprise), or simply because you want to save the money for the CDs/DVDs. In this article I show how to configure a PXE server that allows you to boot multiple distributions: Ubuntu Edgy/Dapper, Debian Etch/Sarge, Fedora Core 6, CentOS 4.4, OpenSuSE 10.2, and Mandriva 2007.

Setting up a linux firewall and router

iptables is a command line tool which allow system administrators to configure Linux packet filtering ruleset.

Using iptables, you are able to tweak packet filtering, Network Address Translation (NAT) and packet mangling which in the end are going to allow you to secure your server, share your Internet connection and log unwanted traffic.

iptables is not really what we could call an easy to get with tool, but once you know the basis, it won't be that scary.

This tutorial will provide a sample script you can use to share your Internet access and will give an overview on how to use iptables

Should Javascript get more respect?
JavaScript is often ridiculed as the black sheep of programming languages. Nearly every Web developer has cursed JavaScript at one time or another. Until recently, many developers had all but written off JavaScript as a necessary evil at best or a toy at worst. But JavaScript is becoming increasingly important. See why it remains the most broadly available scripting language for Web development and a better choice for developing modern applications.
