Comments: 1 Ubuntu 11.04 Generic - The SysAdmin Way In this tutorial I will guide you trough the setup of Ubuntu 11.04 Generic system the way a good linux system administrator would install it. After it is complete you will have a great starting point for all of your future Ubuntu linux needs. By that I mean the following: If you are using virtual environment, you will have an image that you can clone and convert in any supported virtual format and use it as a starting point for all of your Ubuntu virtual projects. If you install this on a real hardware you can also clone you installation and use it as a starting point on various other machines with similar hardware. I will not cover cloning and conversion in this tutorial. Also as I will edit and tweak few system settings in this tutorial that I will not explain much, I hope this guide will encourage you to further explore those options and Linux in general.

Comments: 4 Setting Up Network RAID1 With DRBD On Debian Squeeze This tutorial shows how to set up network RAID1 with the help of DRBD on two Debian Squeeze systems. DRBD stands for Distributed Replicated Block Device and allows you to mirror block devices over a network. This is useful for high-availability setups (like a HA NFS server) because if one node fails, all data is still available from the other node.

How To Speed Up Drupal 7.7 With Boost And nginx (Debian Squeeze)

Tags: apache, debian, nginx, web server •
Comments: 2 How To Speed Up Drupal 7.7 With Boost And nginx (Debian Squeeze) This tutorial shows how you can speed up your Drupal 7.7 installation on a LAMP stack (Debian Squeeze) with the help of Boost and nginx. Boost provides static page caching for Drupal enabling a very significant performance and scalability boost for sites that receive mostly anonymous traffic. Boost makes sure that your logged-in users always get fresh content by not caching pages for logged-in users. In a first step I will show how to make your site faster by enabling Boost on a normal LAMP stack (Apache2, PHP, MySQL), and in a second step I explain how to make your site even faster by using nginx as a reverse proxy sitting in front of Apache and delivering the static HTML pages cached by Boost. nginx delivers static files a lot of faster than Apache and uses less memory/CPU.

Comments: 22 Xtables-Addons On Centos 6 & Iptables GeoIP Filtering This tutorial will explain how to install aditional modules for the kernel to use with iptables rules sets (netfilter modules). Xtables-addons is the successor to patch-o-matic(-ng). Likewise, it contains extensions that were not, or are not yet, accepted in the main kernel/iptables packages. Xtables-addons is different from patch-o-matic in that you do not have to patch or recompile the kernel.

Comments: 1 Setting Up ProFTPd + TLS On Debian Squeeze FTP is a very insecure protocol because all passwords and all data are transferred in clear text. By using TLS, the whole communication can be encrypted, thus making FTP much more secure. This article explains how to set up ProFTPd with TLS on a Debian Squeeze server.
