The Perfect Server - Ubuntu Jaunty Jackalope (Ubuntu 9.04)

This tutorial shows how to set up an Ubuntu Jaunty Jackalope (Ubuntu 9.04) server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Courier POP3/IMAP, Quota, Firewall, etc. In the end you should have a system that works reliably, and if you like you can install the free webhosting control panel ISPConfig 2 (i.e., ISPConfig runs on it out of the box).
I will use the following software:
• Web Server: Apache 2.2 with PHP 5.2.6, Python, Ruby, and WebDAV
• Database Server: MySQL 5.0
• Mail Server: Postfix
• DNS Server: BIND9
• FTP Server: proftpd
• POP3/IMAP: I will use Maildir format and therefore install Courier-POP3/Courier-IMAP.
• Webalizer for web site statistics
Please note that this setup does not work for ISPConfig 3! It is valid for ISPConfig 2 only!
I want to say first that this is not the only way of setting up such a system. There are many ways of achieving this goal but this is the way I take. I do not issue any guarantee that this will work for you!

1 Requirements
To install such a system you will need the following:
• the Ubuntu 9.04 server CD, available here: ftp://releases.ubuntu.com/releases/9.04/ubuntu-9.04-server-i386.iso (i386) or ftp://releases.ubuntu.com/releases/9.04/ubuntu-9.04-server-amd64.iso (x86_64)
• a fast Internet connection.

2 Preliminary Note
In this tutorial I use the hostname server1.example.com with the IP address 192.168.0.100 and the gateway 192.168.0.1. These settings might differ for you, so you have to replace them where appropriate.
