This tutorial shows how to set up a CentOS 5.0 server that offers all services needed by ISPs and web hosters: Apache web server (SSL-capable), 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 CentOS 5.0, but should apply to the 64-bit version with very little modifications as well.

This guide documents how to configure a WebDAV resource using SSL and two-factor authentication and how to access that resource from Windows, Linux and Mac.

This tutorial shows how you can create backups of LVM partitions with an LVM feature called LVM snapshots. An LVM snapshot is an exact copy of an LVM partition that has all the data from the LVM volume from the time the snapshot was created. The big advantage of LVM snapshots is that you do not have to worry about open files and database connections, and you do not have to interrupt/halt services on the live partition because a snapshot is usually created in fractions of a second, so your users will not notice any disruption, and your snapshot holds consistent data.

Proftpd is an excellent FTP server with many features. Wouldn't it be nice to see who is connected to your FTP server and what they are doing all in a convenient web-interface? phpftpwho allows you to see who is accessing your Proftpd FTP server all in a convenient web-interface. It is simple to install and only requires Proftpd, Apache, and PHP.

This tutorial shows how you can install InnoTek's VirtualBox on a Ubuntu desktop. With VirtualBox you can create and run guest operating systems (virtual machines) such as Linux and Windows under a host operating system. There are two ways of installing VirtualBox: from precompiled binaries that are available for some distributions and come under the PUEL license, and from the sources that are released under the GPL. This article will show both ways.

This guide shows how to install three different Internet Explorer versions (6.0, 5.5, and 5.0) on Ubuntu Feisty Fawn, Edgy Eft and Dapper Drake desktops. This is good for people such as web designers who have switched to Linux but still need to test their web sites in Internet Explorer. In addition to that, there are still a few web sites out there that work only in Internet Explorer.

Today security is one of the key aspects in our daily life - sometimes conscious, sometimes unconscious. Security has many aspects and one of them is computer security or security of your or your business' computer data. In this tutorial I will show how to encrypt a whole disk drive using (X)Ubuntu Feisty, dm-crypt, and LUKS. The article also contains some legal considerations.

This tutorial shows how to set up a Debian Etch (Debian 4.0) based server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Courier POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the 32-bit version of Debian Etch, but should apply to the 64-bit version with very little modifications as well.

This article shows how you can make your scanner (SCSI or USB) work with SANE/XSANE from a normal user account without getting permission errors.

You might have noticed that fonts are quite fuzzy on Linux desktops which can make your eyes ache if you have to sit in front of your computer all day long. Font rendering is still a little bit awkward and one of the last weaknesses of Linux desktops. This tutorial shows how you can make GNOME and all GNOME applications (such as Evolution, the file browser Nautilus, etc.) use sharp fonts. In fact, we will use the Microsoft Windows standard font, Tahoma, as the standard font in GNOME, too, which will make the desktop look quite familiar if you are used to working with a Windows desktop.

This tutorial shows how you can install and configure Beryl on an Ubuntu 7.04 (Feisty Fawn) desktop with an ATI Radeon graphic card. With Beryl, you can make your desktop use beautiful 3D effects. We will use the open-source ATI driver that comes with Ubuntu plus AIGLX to achieve this; the other way to do this would be to use the closed-source ATI driver together with XGL which seems to be a bit unstable.

This tutorial shows how to harden PHP5 with Suhosin on Debian Etch and Ubuntu servers. Suhosin is an advanced protection system for PHP installations that was designed to protect servers and users from known and unknown flaws in PHP applications and the PHP core. Suhosin comes in two independent parts, that can be used separately or in combination. The first part is a small patch against the PHP core, that implements a few low-level protections against bufferoverflows or format string vulnerabilities and the second part is a powerful PHP extension that implements all the other protections.

This short guide describes how you can configure your GNOME desktop to display various icons such as My Computer, Network Servers, Trash, etc. on the desktop. By default, these items are placed on one of the panels (Trash) or hidden in the Places menu. Having these icons on the desktop is useful if you switch from a Windows desktop to a GNOME desktop and are used to having them on the desktop.

This article offers a simple way of creating DVD images of Debian or Ubuntu http/ftp repositories. Ubuntu does not offer DVDs ready to download with its main, universe, multiverse and/or restricted repositories. With the contents of this guide you can do it yourself. Having the Ubuntu or Debian repositories on DVD can be useful for those users who do not have access to the internet where they have their Ubuntu installed but have access somewhere else to download the repository and build and burn the DVDs.

This method uses crontab to execute a shell script that downloads an updated urchin.js file every 24 hours and saves it into your local sites directory so that it can be served by your web server instead of the google-analytics.com web server. The problem with google-analytics.com is that when google-analytics.com/urchin.js is requested by billions of web users all over the world at one time, it can cause your pages to load very slowly, especially if you are using WordPress or a similar CMS.

This tutorial provides step-by-step instructions on how to install VMware Server on a Mandriva Free 2007 desktop system. With VMware Server you can create and run guest operating systems (virtual machines) such as Linux, Windows, FreeBSD, etc. under a host operating system. This has the benefit that you can run multiple operating systems on the same hardware which saves a lot of money, and you can move virtual machines from one VMware Server to the next one (or to a system that has the VMware Player which is also free).

With this guide I explain how to set up suPHP on a Debian based ISPConfig server with PHP 4. When you have configured suPHP on your ISPConfig server, you are able to run the PHP scripts under the admin user of the website instead of the Apache user.

This is a detailed description about how to set up a Ubuntu based server (Ubuntu 6.10) to act as a file- and printserver for Windows workstations in small workgroups. This howto uses the tdb backend for SAMBA to store passwords and account information. This is suitable for workgroups for up to 250 users and is easier to set up than an LDAP backend.

I wanted to access the internet over bluetooth instead of GPRS/3G network from my mobile phone (SE K800i). After a lot of searching I couldn't find a clear explanation as how to accomplish this. I did manage to set it up with Windows XP, using the "Personal Area Network" in the bluetooth utility and doing internet connection sharing. After another fruitless search, I managed to figure out how to make a bluetooth internet profile instead of GPRS or 3G on the phone. Since I work in Linux most of the time, I decided to have a go and do it with Debian, my workstation's main OS. After spending a few hours, I had it working using the steps below.

This tutorial shows how you can import Outlook Express emails, contacts, and account settings into Mozilla Thunderbird and Evolution. This is quite useful if you want to switch from Windows to Linux but do not want to lose your mails and address book. The procedure should be similar if you use Outlook instead of Outlook Express.
