Virtualization With KVM On A Mandriva 2010.0 Server
===================================================

This guide explains how you can install and use KVM for creating and running virtual machines on a Mandriva 2010.0 server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM). KVM is short for Kernel-based Virtual Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware virtualization, e.g. Intel VT or AMD-V.

VBoxHeadless - Running Virtual Machines With VirtualBox 3.1.x On A Headless Mandriva 2010.0 Server
==================================================================================================

This guide explains how you can run virtual machines with Sun VirtualBox 3.1.x on a headless Mandriva 2010.0 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.

Tweaking Hidden Settings With Ubuntu Tweak On Ubuntu 9.10
=========================================================

Ubuntu Tweak is a tool that lets you change hidden Ubuntu settings, for example: hide or change the splash screen, show or hide the Computer, Home, Trash, and Network icons, change Metacity, Nautilus, power management, and security settings, etc. Currently Ubuntu Tweak is available only for the Ubuntu GNOME desktop, i.e., it will not work on Kubuntu or Xubuntu. This short guide shows how to install and use Ubuntu Tweak.

Distributed Replicated Storage Across Four Storage Nodes With GlusterFS On CentOS 5.4
=====================================================================================

This tutorial shows how to combine four single storage servers (running CentOS 5.4) to a distributed replicated storage with GlusterFS. Nodes 1 and 2 (replication1) as well as 3 and 4 (replication2) will mirror each other, and replication1 and replication2 will be combined to one larger storage server (distribution). Basically, this is RAID10 over network. If you lose one server from replication1 and one from replication2, the distributed volume continues to work. The client system (CentOS 5.4 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

How To Set Up WebDAV With Apache2 On OpenSUSE 11.2
==================================================

This guide explains how to set up WebDAV with Apache2 on an OpenSUSE 11.2 server. WebDAV stands for Web-based Distributed Authoring and Versioning and is a set of extensions to the HTTP protocol that allow users to directly edit files on the Apache server so that they do not need to be downloaded/uploaded via FTP. Of course, WebDAV can also be used to upload and download files.

Virtual Hosting With PureFTPd And MySQL (Incl. Quota And Bandwidth Management) On OpenSUSE 11.2
===============================================================================================

This document describes how to install a PureFTPd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota and upload/download bandwidth limits with this setup. Passwords will be stored encrypted as MD5 strings in the database.

Installing PowerDNS With MySQL On CentOS
========================================

PowerDNS is a MySQL-based DNS server, written in C++ and licensed under the GPL. PowerDNS can be managed through a web interface (PowerAdmin). This guide shows how to install it on CentOS.

Installation Of BIND As A Secondary (Slave) DNS Server On CentOS
================================================================

After we have installed BIND as a master DNS server (NS1), we can now try to set up a secondary DNS server (NS2) with BIND on CentOS. NS2 acts as a backup if there are problems with NS1.
