Basic Linux system auditing is a bit tricky and data collected and information of that is out of place and readability is not that good. Recently this lead me to put together a Open Source code project and develop simple BASH scripts that do the job nicely. The code and tar ball can be downloaded from both google code or from SourceForge's website and the project website has links to documentation, help, installation and code.

Dualbooting means having installed two operating systems on one hard disk and being able to boot from any of them.

This guide explains how you can run virtual machines with VirtualBox 4.1 on a headless Ubuntu 11.10 server. Normally you use the VirtualBox GUI to manage your virtual machines, but a server does not have a desktop environment. Fortunately, VirtualBox comes with a tool called VBoxHeadless that allows you to connect to the virtual machines over a remote desktop connection, so there's no need for the VirtualBox GUI.

This tutorial shows how to prepare a CentOS 6.2 x86_64 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: nginx web server, Postfix mail server, MySQL, BIND nameserver, PureFTPd, SpamAssassin, ClamAV, Mailman, and many more. Since version 3.0.4, ISPConfig comes with full support for the nginx web server in addition to Apache; this tutorial covers the setup of a server that uses nginx, not Apache.

This tutorial shows how you can use a free Class1 SSL Certificate from StartSSL to secure your ISPConfig 3 installation and get rid of self-signed certificate warnings. The guide covers using the SSL certificate for the ISPConfig web interface (both Apache2 and nginx), Postfix (for TLS connections), Courier and Dovecot (for POP3s and IMAPs), and PureFTPd (for TLS/FTPES connections). If you've installed monit and use HTTPS for its web interface, I will show you how to use the StartSSL certificate for it as well. This guide assumes you use Debian or Ubuntu; the principle is the same for other distributions supported by ISPConfig 3, but paths might differ.

This article is about how to watch YouTube videos on your desktop with a tool called Minitube. Minitube is a piece of software with a nice GUI that lets you enter keywords into a searchbar just like on youtube.com to display a list where you can choose your desired video from. It is then played directly in the graphical interface without the need to install any flash player for your browser or even open it.

This tutorial describes the installation of an OpenVZ host server to manage virtual machines from within the ISPConfig 3 hosting control panel. OpenVZ is a lightweight virtualization technology for Linux servers, similar to jails on *BSD systems.

This tutorial shows how you can install and run a TYPO3 (version 4.6) web site on a Debian Squeeze or Ubuntu 11.10 system that has nginx installed instead of Apache (LEMP = Linux + nginx (pronounced "engine x") + MySQL + PHP). The guide also covers the use of the nc_staticfilecache extension which allows TYPO3 to cache pages as complete .html files for faster delivery (increases response times for static pages by a factor of 230; it's similar to Drupal's Boost module). nginx is a HTTP server that uses much less resources than Apache and delivers pages a lot of faster, especially static files.

This HOWTO will show you how to set up a Squid proxy server deployed on CentOS or RedHat 6 Linux with web and content filtering done by QuintoLabs Content Security with proxy users transparently authenticated by Windows 2008 R2 based Active Directory. This is the work in progress and all comments are welcomed. The HOWTO is targeted at novice users and may sometimes seem too thorough for more advanced gurus. No compilation magic will be involved in our setup so any system administrator accustomed to Windows will be able to easily follow the instructions.

This tutorial is supposed to show some features of the Enlightenment window manager as an alternative to the often used Gnome and KDE managers. I will install Enlightenment on a desktop computer with Ubuntu 11.10 installed. Apart from the login screen however, all of the controls shown on the screenshots should be the same for every installation of enlightenment, whatever distribution you install it on. Enlightenment is already included in the Ubuntu repositories, therefore Ubuntu users and those of any Ubuntu derivatives won't have any problems installing it. It is also available for download for most other distributions though.

Nginx (pronounced "engine x") is a free, open-source, high-performance HTTP server. Nginx is known for its stability, rich feature set, simple configuration, and low resource consumption. This tutorial shows how you can install Nginx on an OpenSUSE 12.1 server with PHP5 support (through PHP-FPM) and MySQL support.
