19 Oct 08 Exim, MySQL, Courier IMAP, Courier POP3 & Spamassassin – vdomain and vuser set up.

There’s a couple of guides out there on how to set up Exim, MySQL, Courier and Spamassassin in a virtual user environment but I thought I’d put together a high level basic guide myself.

My installation is running on debian etch 4.0 stable (2.6.18-6-686)

As this is a vdomain/vuser setup, you will not require a system shell/login for the users you add.

To start off, just install the packages you’ll need with apt-get:

Now if you already have exim4-* installed which is the default, you have two choices. We want to install our own exim version from source but without breaking the repository. The choices are to either just rename exim4 to exim4.old and then create your new exim install, or alternatively create a dummy empty exim4 package remove exim4-* and install your dummy package. This will resolve the dependancies issue in the package manager. Neither method is particularly clean – I have installed a dummy package personally and removed the real exim4 set of packages.

15 Sep 08 Quick Linux and Windows OpenVPN HOWTO and tutorial, including VPN routing

OpenVPN is a popular Windows/Linux VPN Server/Client pair. I think there’s a separate GUI available for it if you’re so minded. This howto will cover command line usage only.

I’ll provide example configuration based on a Linux server and a Windows client, however the same applies pretty easily if you wanted to mix and match.

On debian, apt-get install openvpn. On any other linux distro, use your own package manager or alternatively download from source and compile.
