The Perfect Server - CentOS 5.4 x86_64 [ISPConfig 2]
====================================================

This tutorial shows how to set up a CentOS 5.4 server (x86_64) that offers all services needed by ISPs and web hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Dovecot POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the 64-bit version of CentOS 5.4, but should apply to the 32-bit version with very little modifications as well. In the end you should have a system that works reliably, and if you like you can install the free webhosting control panel ISPConfig (i.e., ISPConfig runs on it out of the box).

Preparing An Ubuntu Machine For Upgrade
=======================================

The Debian / Ubuntu upgrade mechanism is a wonderful piece of software. When the new release comes out, just follow the instructions given by the update manager and the upgrade will be done almost automatically. Sometimes Ubuntu asks for your help when you made other changes than the upgrade program itself wants to make. This howto gives a few tips on how to make your Ubuntu installation more upgrade-friendly. I tested it on Ubuntu installations, but the mechanisms in this howto should not be different for Debian.

How To Enable Networking In Xen Guests On Hetzner's New EQ Servers (Debian Lenny)
=================================================================================

This tutorial shows how you can enable networking in Xen guests (domU) on Hetzner's new EQ servers. With the new EQ servers, you can get up to three additional IPs that are in the same subnet as the server's main IP. The problem is that these additional IPs are bound to the MAC address of the host system (dom0) - Hetzner's routers will dump IP packets if they come from an unknown MAC address. This means we cannot use Xen's bridged mode, but must switch to Xen's routed mode where the host system (dom0) acts as the gateway for the guests.

Virtual Hosting With PureFTPd And MySQL (Incl. Quota And Bandwidth Management) On Ubuntu 9.04 (Jaunty Jackalope)
================================================================================================================

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.

Virtual Hosting With Proftpd And MySQL (Incl. Quota) On Ubuntu 9.04
===================================================================

This document describes how to install a Proftpd 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 with this setup.

How To Install Django On Mandriva 2009.1 (Apache2/mod_python)
=============================================================

This tutorial explains how to install Django on a Mandriva 2009.1 server. Django is a web framework that allows to develop Python web applications quickly with as much automation as possible. I will use it with Apache2 and mod_python in this guide.

Troubleshooting Common DNS Misconfiguration Errors
==================================================

DNS (Domain name system) may not be known to most people who use the Internet but it is the real invisible force driving the Internet without which everyone would be seeing numbers and IPs. The whole meaning of domain names exists today just because of DNS.

Evolving A Database With MySQL
==============================

This tutorial explains how to "grow" your own database definition in a way that is maintainable, by using so-called "recreate" scripts. These scripts can be used to both create a database from scratch and update an existing database.
