Setting Up Master-Master Replication On Four Nodes With MySQL 5 On Debian Etch
This tutorial explains how you can set up MySQL master-master replication on four MySQL nodes (running on Debian Etch). The difference to a two node master-master replication is that if you have more than two nodes, the replication goes in a circle, i.e., with four nodes, the replication goes from node1 to node2, from node2 to node3, from node3 to node4, and from node4 to node1.
Hardening The Linux Kernel With Grsecurity (Debian)
Security is based on three characteristics: prevention, protection and detection. Grsecurity is a patch for Linux kernel that allows you to increase each of these points. This howto was performed on a Debian Lenny system. Thus some tools are Debian specific. However, tasks can be performed with other distro specific tools or even with universal tools (make).
Installing The Link Layer Topology Discovery (LLTD) Protocol Responder For Linux On Debian Lenny
This document describes how to install and configure the Link Layer Topology Discovery (LLTD) Protocol - Responder Source Code from Microsoft. The lld2d daemon allows linux systems to display in Vista's Network Map. This How-To should be easily adaptable to other distros.

phpsh is an interactive shell for php that features readline history, tab completion, quick access to documentation. It was developed at Facebook and ironically, is written mostly in python. This article explains how you can install/use it on a Debian Etch system.
Using IPv6 On Debian Etch
This document describes how you can configure a Debian Etch system for IPv6 so that a) it can connect to other IPv6 hosts and b) other IPv6 hosts can connect to it. IPv6 should become more important in the future as recent estimates assume that there will be no more IPv4 addresses left by 2010 or 2011. Therefore it's time time to learn IPv6.
Installing ISP-fw (Firewall) On Linux

Preventing MySQL Injection Attacks With GreenSQL On Debian Etch
GreenSQL (or greensql-fw) is a firewall for MySQL databases that filters SQL injection attacks. It works as a reverse proxy, i.e., it takes the SQL queries, checks them, passes them on to the MySQL database and delivers back the result from the MySQL database. It comes with a web interface (called greensql-console) so that you can manage GreenSQL through a web browser. This guide shows how you can install GreenSQL and its web interface on a Debian Etch server.
Integrating APC (Alternative PHP Cache) Into PHP5 And Lighttpd (Debian Etch)
This guide explains how to integrate APC (Alternative PHP Cache) into PHP5 and lighttpd on a Debian Etch system. APC is a free and open PHP opcode cacher for caching and optimizing PHP intermediate code. It's similar to other PHP opcode cachers, such as eAccelerator and XCache.
