Using ATA Over Ethernet (AoE) On Ubuntu 12.04 (Initiator And Target)
This guide explains how you can set up an AoE target and an AoE initiator (client), both running Ubuntu 12.04. AoE stands for "ATA over Ethernet" and is a storage area network (SAN) protocol which allows AoE initiators to use storage devices on the (remote) AoE target using normal ethernet cabling. "Remote" in this case means "inside the same LAN" because AoE is not routable outside a LAN (this is a major difference compared to iSCSI). To the AoE initiator, the remote storage looks like a normal, locally-attached hard drive.

Managing Multiple MySQL Servers From One phpMyAdmin Installation (Using SSL Encryption)
This tutorial explains how you can manage multiple MySQL servers from one phpMyAdmin installation. For security reasons, communication between phpMyAdmin and any remote MySQL server is using SSL encryption (this is not necessary for a local MySQL server since communication between phpMyAdmin and MySQL is not leaving the server). phpMyAdmin is a free software tool written in PHP, intended to handle the administration of MySQL over the World Wide Web. phpMyAdmin supports a wide range of operations with MySQL.
Installing mod_geoip for Apache2 On Ubuntu 12.04

Creating Advanced MySQL-Based Virtual Hosts On Lighttpd (Ubuntu 12.04)
This guide explains how you can create advanced virtual hosts on a lighttpd web server on Ubuntu 12.04 that are stored in a MySQL database. The method described here does not use the lighttpd mod_mysql_vhost module, and unlike mod_mysql_vhost (which allows you to store only the hostname and document root of a vhost in a database), this method allows to store individual configuration directives for each vhost in the MySQL database.
