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.</p> <a href="http://www.howtoforge.com/installing-and-using-openvz-on-debian-etch" title="Read the rest of this posting." class="read-more">Read more...</a> Debian Virtualization Thu, 22 May 2008 19:03:43 +0200 http://www.howtoforge.com/installing-and-using-openvz-on-debian-etch http://www.howtoforge.com/installing-and-using-openvz-on-debian-etch#comment http://www.howtoforge.com/how-to-configure-rtgui-for-rtorrent <p><b>How To Configure rtGui For rTorrent</b></p> <p> This tutorial explains how you can install a GUI (rtGUI) for rTorrent.</p> <a href="http://www.howtoforge.com/how-to-configure-rtgui-for-rtorrent" title="Read the rest of this posting." class="read-more">Read more...</a> Debian Thu, 22 May 2008 14:09:10 +0200 http://www.howtoforge.com/how-to-configure-rtgui-for-rtorrent http://www.howtoforge.com/how-to-configure-rtgui-for-rtorrent#comment http://www.howtoforge.com/manage-your-laptop-hotkeys-on-fedora <p><b>Manage Your Laptop's Hotkeys On Fedora</b></p> <p>This document describes how to make your laptop's hotkeys usable on Fedora.

I'll 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 <b>SMTP-AUTH</b> and <b>TLS</b> and <b>quota</b> (quota is not built into Postfix by default, I'll show how to patch your Postfix appropriately). Passwords are stored in <b>encrypted</b> form in the database (most documents I found were dealing with plain text passwords which is a security risk). In addition to that, this tutorial covers the installation of <b>Amavisd</b>, <b>SpamAssassin</b> and <b>ClamAV</b> so that emails will be scanned for spam and viruses. I will also show how to install <b>SquirrelMail</b> as a webmail interface so that users can read and send emails and change their passwords.</p> <a href="http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-ubuntu8.04" title="Read the rest of this posting." class="read-more">Read more...</a> Anti-Spam/Virus Ubuntu Postfix Tue, 20 May 2008 18:13:58 +0200 http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-ubuntu8.04 http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-ubuntu8.04#comment http://www.howtoforge.com/compile-rtorrent-from-svn-ubuntu-8.04-hardy-heron <p><b>HowTo Compile rTorrent From SVN In Ubuntu 8.04 Hardy Heron</b></p> <p>Torrent is a great way to transfer large files very quickly.

If the PIN is correct, the encryption valid and the account active, a one-time password is generated, encrypted and returned to the user's token where it is decrypted and presented for use with a network-based services.

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've compiled lighttpd yourself, then the second way is for you: it shows how to build mod_geoip.so for your lighttpd version.</p> <a href="http://www.howtoforge.com/installing-mod_geoip-for-lighttpd-on-debian-etch" title="Read the rest of this posting." class="read-more">Read more...</a> Debian Thu, 15 May 2008 17:52:44 +0200 http://www.howtoforge.com/installing-mod_geoip-for-lighttpd-on-debian-etch http://www.howtoforge.com/installing-mod_geoip-for-lighttpd-on-debian-etch#comment http://www.howtoforge.com/how-to-change-your-login-screen-in-fedora8-gnome <P><B>How To Change Your Login Screen In Fedora 8</b></p> <P>This is a simple howto on changing your log on screen.

No data stored on an encrypted volume can be read (decrypted) without using the correct password/keyfile(s) or correct encryption keys.
