This short tutorial shows you how to install OpenSSL on Ubuntu 12.04. The process is very simple. For this tutorial, I'll be installing openssl version 0.9.8e and the latest 1.0.1g (released Apr 07, 2014). Linux kernel is 3.2.0-23-powerpc-smp. I have used a Mac Mini (powerpc/ppc architecture).

Last week, my company decided to use a different webmail client with a better look and feel. I was assigned the job of searching for a good webmail client. I came up with some commercial ones and some free ones. My project leader shortlisted two of them (i) Round Cube (ii) atmail. I was asked to to do a demo setup of Round Cube. He did not like it because it was lacking some features that we wanted and also it wasn't a stable release then. Then I tried installing atmail on my Mac OS X Server machine. I tried to follow all the instructions from their website but couldn't get it to work properly. I emailed atmail's technical support team but they referred me to their knowledge base. I could not find instructions for Mac OS X Server there. Atmail Technical Support charges $100 for a remote installation of their product but my project leader wanted me to do it myself so that someone in the company could understand the product better.

In this tutorial I'll tell you the very basic steps on how to install a Debian Linux Distribution on your computer. Although this tutorial should help majority of the users install Debian but my main focus will be on hardening the Debian installation after the installation process. Also, I am assuming that you want to install Debian as a server not as a game or workstation PC. If you are looking for more detailed information on Debian installation then refer to the Debian manual and come back to this tutorial after installation. You can find the manual in your language and for your platform http://www.debian.org/releases/stable/installmanual.
