The storage capacity and data retrieval speeds of Hard Disks have increased multiple folds in last few years. However for large business organizations, which not only need to store terabytes of invaluable data but access them frequently as well. These organizations cannot afford to let their systems go offline even for a short duration of time. Moreover they cannot even think of losing even small amount of data due to disk failure or for that matter any other reason.

This document describes how to set up PHPlist on Fedora, CentOS, Ubuntu and Debian. This howto should also work for other distributions with little modifications. Taken from the phplist page: "phplist is an open-source newsletter manager. phplist is free to download, install and use, and is easy to integrate with any website. phplist is downloaded more than 10 000 times per month and is listed in the top open source projects for vitality score on Freshmeat."

This tutorial describes how to set up a TeamSpeak server on an Ubuntu Server system. Teamspeak has the ability to make more than one server by setting different ports for each server. The user that controls all these servers is called the SuperAdmin, he has the ability to make more servers and users with or without their rights.

In this HowTo I will describe how to prepare a Debian Etch server for OpenVZ. With OpenVZ you can create multiple Virtual Private Servers (VPS) on the same hardware, similar to Xen and the Linux Vserver project. OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution used by many providers that offer virtual servers. The OpenVZ kernel patch is licensed under the GPL license, and the user-level tools are under the QPL license.

This document describes how to make your laptop's hotkeys usable on Fedora. I've tested this with Fedora 8 but it should also work with other Fedora versions - and maybe, with a little modification, also with other distributions.

This document describes how to install a Postfix mail server based that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I will also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota. Passwords are stored in encrypted form in the database. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.

Torrent is a great way to transfer large files very quickly. However most torrent clients are gui based and have quite some impact on system resources (e.g. Azureus). rTorrent is a lightweight client running from the terminal. Being able to run it in a screen session (also upon boot) makes it ideal to also control it from a remote location.

This document describes how to upgrade your desktop from Fedora 8 to Fedora 9 via PreUpgrade. PreUpgrade provides a frontend that allows the user to easily download all packages that are needed for the distribution upgrade, and then perform the distribution upgrade.

This document describes step-by-step how to set up a Fedora 9 desktop (GNOME). The result is a fast, secure and extendable system that provides all you need for daily work and entertainment.

This guide explains how to set up mod_geoip with lighttpd on a Debian Etch system. mod_geoip looks up the IP address of the client end user. This allows you to redirect or block users based on their country. You can also use this technology for your OpenX (formerly known as OpenAds or phpAdsNew) ad server to allow geo targeting. I will show two ways to build mod_geoip - the first way is to build a new lighttpd .deb package (including mod_geoip) which is the way I recommend. This works only if you have installed the standard Debian Etch lighttpd package. If you have compiled lighttpd yourself, then the second way is for you: it shows how to build mod_geoip.so for your lighttpd version.

This is a detailed description about how to set up a Fedora 9 server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable) with PHP5 and Ruby, Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Dovecot POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the 32-bit version of Fedora 9, but should apply to the 64-bit version with very little modifications as well.

This tutorial deals only with how to add an extra encrypted physical volume to a volume group pool containing other encrypted physical volumes. This is typical scenario if, at first, you have set up your encryption at a physical partition level (/dev/sdaX where X is the a number of your partition), then you set up your LVM on top of the encrypted partition. If at some later time you want to add another partition in your volume group, you will also want to have it encrypted in order to maintain the same level of security.

This document describes how to set up TrueCrypt 5.1a on Debian Etch (GNOME). Taken from the TrueCrypt page: "TrueCrypt is a software system for establishing and maintaining an on-the-fly-encrypted volume (data storage device). On-the-fly encryption means that data are automatically encrypted or decrypted right before they are loaded or saved, without any user intervention. No data stored on an encrypted volume can be read (decrypted) without using the correct password/keyfile(s) or correct encryption keys. Entire file system is encrypted (e.g., file names, folder names, contents of every file, free space, meta data, etc)."

This document describes how to reconfigure the default language and the keyboard layout on various distributions so that they suit your location.

This document describes how to enable and configure Compiz Fusion on a Mandriva One 2008.1 Spring GNOME desktop with an NVIDIA graphics card.

This document describes how to set up and use Sabayon on Fedora 8. Taken from the Sabayon page: "Sabayon is a system administration tool to manage GNOME desktop settings. Sabayon provides a sane way to edit GConf defaults and GConf mandatory keys: the same way you edit your desktop. Sabayon launches profiles in an Xnest window. Any changes you make in the Xnest window are saved back to the profile file, which can then be applied to user's accounts."
