How To Set Up A USB-Over-IP Server And Client With Mandriva 2010.0
==================================================================

This tutorial shows how to set up a USB-over-IP server with Mandriva 2010.0 as well as a USB-over-IP client (also running Mandriva 2010.0). The USB/IP Project aims to develop a general USB device sharing system over IP network. To share USB devices between computers with their full functionality, USB/IP encapsulates "USB I/O messages" into TCP/IP payloads and transmits them between computers. USB-over-IP can be useful for virtual machines, for example, that don't have access to the host system's hardware - USB-over-IP allows virtual machines to use remote USB devices.

Server Monitoring With munin And monit On Mandriva 2010.0
=========================================================

In this article I will describe how you can monitor your Mandriva 2010.0 server with munin and monit. 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, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.

When To Use Indexes In MySQL
============================

This comes up in discussions almost every new project I work on, because it's a very important thing to consider when designing a database. When deciding when and how to create an index in your MySQL database, it's important to consider how the data is being used.

Chrooting Apache2 With mod_chroot On Debian Lenny
=================================================

This guide explains how to set up mod_chroot with Apache2 on a Debian Lenny system. With mod_chroot, you can run Apache2 in a secure chroot environment and make your server less vulnerable to break-in attempts that try to exploit vulnerabilities in Apache2 or your installed web applications.

How To Install Z-Push On An ISPConfig 3 Server (Debian Lenny)
=============================================================

Z-push is an implementation of the ActiveSync protocol which is used 'over-the-air' for multi platform ActiveSync devices, including Windows Mobile, iPhone, Sony Ericsson and Nokia mobile devices. With Z-push any groupware can be connected and synced with these devices. This install of Z-Push is on a The Perfect Server - Debian Lenny (Debian 5.0) [ISPConfig 3] setup.

Ubuntu Server 9.04 Bacula Bweb GUI
==================================

Bweb is a perl based web program that provides a tool to do basic operations and get statistics. It obtains its information from your catalog database and the bconsole program.

Using iRedMail And OpenVPN For Virtual Email Hosting And VPN Services (CentOS 5.4)
