VBoxHeadless - Running Virtual Machines With VirtualBox 3.1 On A Headless Ubuntu 9.10 Server
============================================================================================

This guide explains how you can run virtual machines with Sun VirtualBox 3.1 on a headless Ubuntu 9.10 server. Normally you use the VirtualBox GUI to manage your virtual machines, but a server does not have a desktop environment. Fortunately, VirtualBox comes with a tool called VBoxHeadless that allows you to connect to the virtual machines over a remote desktop connection, so there's no need for the VirtualBox GUI.

How To Back Up MySQL Databases With mylvmbackup On Debian Lenny
===============================================================

mylvmbackup is a Perl script for quickly creating MySQL backups. It uses LVM's snapshot feature to do so. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, creates a snapshot of the volume containing the MySQL data directory, and unlocks the tables again. This article shows how to use it on a Debian Lenny server.

Setting Up A PXE Install Server On Ubuntu 9.10
==============================================

This tutorial shows how to set up a PXE (short for preboot execution environment) install server with Ubuntu 9.10 (Karmic Koala). 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.

Installing mod_geoip for Apache2 On Ubuntu 9.10
===============================================

This guide explains how to set up mod_geoip with Apache2 on an Ubuntu 9.10 system. mod_geoip looks up the IP address of the client end user. This allows you to redirect or block users based on their country. You can also use this technology for your OpenX (formerly known as OpenAds or phpAdsNew) ad server to allow geo targeting.

How To Set Up A USB-Over-IP Server And Client With OpenSUSE 11.2
================================================================

This tutorial shows how to set up a USB-over-IP server with OpenSUSE 11.2 as well as a USB-over-IP client (also running OpenSUSE 11.2). 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.

How To Set Up Apache2 With mod_fcgid And PHP5 On OpenSUSE 11.2
==============================================================

This tutorial describes how you can install Apache2 with mod_fcgid and PHP5 on OpenSUSE 11.2. mod_fcgid is a compatible alternative to the older mod_fastcgi. It lets you execute PHP scripts with the permissions of their owners instead of the Apache user.

Trafficanalysis Using Debian Lenny
==================================

By using my Network Monitoring Appliance we noticed a link in MRTG always under heavy load. On this link a lot of different traffic aggregates, so we decided to analyze of what quantities of protocols and therefore applications the cumulative traffic consists.

How To Configure ISA Proxy/Auth Setting For Yum
===============================================

I was running CentOS in my LAN for my personal use and there are MS ISA servers for proxying and each user has to use his/her user name & password for Internet. So when I used my credentials in my web browser I had no problem but when I was going to do yum no success. After some googling I found this solution.
