How to Build an Effective Mail Server Defense
When speaking of mail server-related security, one
tends to limit the issue to message applied security measures, and even
more to Antivirus and Antispam protection. This is however only one
stage in the more complex process of securing your server. This article
aims at identifying and explaining all security layers, highly important when choosing a certain mail server and consequently when configuring and using it.
Setting up Subversion and websvn on Debian
This howto will illustrate a way to install and configure Subversion and websvn on a Debian server. I will not specifically configure inetd with svnserve in this howto. Rest assured that Subversion will be totally functional without it. You can copy/paste most of the howto to get it working.
Virtual Users And Domains With Postfix, Courier And MySQL (Fedora Core 5)
This document describes how to install a mail server based on Postfix that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. 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. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses.
MySQL Master Master Repliction Tutorial
This tutorial describes how to set up MySQL master-master replication. We need to replicate MySQL servers to achieve high-availability (HA). In my case I need two masters that are synchronized with each other so that if one of them drops down, other could take over and no data is lost. Similarly when the first one goes up again, it will still be used as slave for the live one.

Building A Virtual Server (VPS) With Debian 3.1 (Sarge) And OpenVZ
In this HowTo I will describe the steps to be taken to prepare a server for OpenVZ virtual machines on Debian 3.1 (Sarge) 32Bit Linux. 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 tutorial shows how to install the Flash player on a Linux system. It was tested on Dapper Drake (on an x86 - 32 bit machine).
LDAP Authentication In Linux
This howto will show you howto store your users in LDAP and authenticate some of the services against it. I will not show howto install particular packages, as it is distribution/system dependant. I will focus on "pure" configuration of all componenets needed to have LDAP authentication/storage of users. The howto assumes somehow, that you are migrating from a regular passwd/shadow authentication, but it is also suitable for people who do it from scratch.
