This tutorial shows how to prepare a Debian Squeeze (Debian 6.0) server for the installation of ISPConfig 3, and how to install ISPConfig 3. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: Apache web server, Postfix mail server, MySQL, BIND nameserver, PureFTPd, SpamAssassin, ClamAV, and many more.

Please note that this setup does not work for ISPConfig 2! It is valid for ISPConfig 3 only!

I do not issue any guarantee that this will work for you!


1 Requirements

To install such a system you will need the following:


2 Preliminary Note

In this tutorial I use the hostname with the IP address and the gateway These settings might differ for you, so you have to replace them where appropriate.


3 The Base System

Insert your Debian Squeeze network installation CD into your system and boot from it. Select Install (this will start the text installer - if you prefer a graphical installer, select Graphical install):

Choose your language:

Then select your location:

If you've selected an uncommon combination of language and location (like English as the language and Germany as the location, as in my case), the installer might tell you that there is no locale defined for this combination; in this case you have to select the locale manually. I select en_US.UTF-8 here:

Choose a keyboard layout:

The installer checks the installation CD, your hardware, and configures the network with DHCP if there is a DHCP server in the network:

Enter the hostname. In this example, my system is called, so I enter server1:

Enter your domain name. In this example, this is

Afterwards, give the root user a password:

Confirm that password to avoid typos:

Create a normal user account, for example the user Administrator with the user name administrator (don't use the user name admin as it is a reserved name on Debian Squeeze):

With this configuration I am unable to fetchmail in ISPConfig due to not being able to resolve the the domain name of the external mailbox. If i turn off the firewall, dns works fine. If I open all ports > 1000 it works fine. I believe this has something to do with the return port of the dns query to my name server? Maybe iptables?

Great tutorial but even better if it would also describe how to force ISP over a secure connection (https) which is not very hard to configure. E.g. this site describes one way, although enabling ssh is not necessary anymore after fulfilling this tutorial and ISP3 has some standard configuration lines that can be uncommented... (And why isn't ssl standard in ISP3?!?!)

Second, and perhaps a bit more difficult is securing phpmyadmin. I think phpmyadmin as a 'folder' in a website is not very secure since you cannot easily force it to connect over ssl (or can you? Lemme know!) On my server I would prefer phpmyadmin only accessible over ssl.

Isn't FAM necessary for Courier IMAP? Most mailclients seem to complain when it is not installed..
