While there are numerous proprietary e-mail security solutions around, how many actually manage to live up to their claims? And who says that customer service and satisfaction never come free? LFY tries its best to search out a solution that addresses these concerns.
While everyone else seems to be in a race for the latest and the greatest, CentOS 5.3 still bundles pretty old and tested software. Well, this is not your typical desktop OS; besides, the stability makes it a must-have for your server deployments.
A Puppet show can turn out to be real entertainment for UNIX administrators.
In the previous article in this series (‘Data Centre Redundancy’, page 56, April 2009) we got an overview of the architecture associated with data centre redundancy. An important aspect of this is to make sure that the traffic is evenly distributed across all the data centres in order to fully utilise the available capacity. In this concluding article, we will discuss the use of LVS (Linux Virtual Server) to load balance the traffic across data centres.
Let’s explore SELinux modes, and learn a few commands that will help in understanding SELinux policies better.
Understanding the OpenVZ way of virtualisation and getting started with it.
In the Part 4 of “Building a Server from Scratch” series, we learn how to set up a Web and database server.
Introducing Awk, a language that has built-in features to recognise patterns and manipulate them with ease.
In the Part 3 of “Building a Server from Scratch” series, we learn to set up VirtualBox on the main server and deploy each service on a separate virtual machine.

Therefore, we would need to build high-availability in the reverse-proxy server itself.
