Unix+clones SpamAssassin, ClamAV and Procmail Howto
Post date: April 15, 2005, 19:04 Category: Network Views: 1132 Comments: 0
Tutorial quote: This document describes how to install SpamAssassin (for filtering SPAM) and ClamAV (for filtering viruses, trojans, worms, etc.) and how to invoke them by using procmail recipes. It is suitable for scenarios where Sendmail or Postfix deliver emails to local users. It should work (maybe with slight changes concerning paths etc.) on all *nix operating systems. I tested it on Debian Woody so far.

In the end you will have a system where Sendmail or Postfix deliver emails to a local user; the emails are passed to procmail which invokes SpamAssassin and ClamAV in order to filter the emails before they arrive in the user's inbox. However, the installation of Sendmail and Postfix are not covered in this document.

This howto is meant as a practical guide.
Linux How To Back Up MySQL Databases Without Interrupting MySQL
Post date: May 12, 2007, 18:05 Category: System Views: 1138 Comments: 0
Tutorial quote: This article describes how you can back up MySQL databases without interrupting the MySQL service. Normally, when you want to create a MySQL backup, you either have to stop MySQL or issue a read lock on your MySQL tables in order to get a correct backup; if you do not do it this way, you can end up with an inconsistent backup. To get consistent backups without interrupting MySQL, I use a little trick: I replicate my MySQL database to a second MySQL server, and on the second MySQL server I use a cron job that creates regular backups of the replicated database.
Unix+clones Postfix performance tuning
Post date: May 21, 2005, 06:05 Category: Optimizing Views: 1216 Comments: 0
Tutorial quote: Postfix is fast out of the box, but like other packages, you can usually tune it to work even faster. Furthermore, there are situations where Postfix may not perform as well as you expected, whether because of hardware or software limitations on the server system or other adverse conditions, such as a big influx of spam or undeliverable mail. This article shows you how to find and analyze the most common performance problems.
Ubuntu VBoxHeadless - Running VirtualBox 2.0 On A Headless Ubuntu 8.04 Server
Post date: September 25, 2008, 08:09 Category: Miscellaneous Views: 1565 Comments: 0
Tutorial quote: This guide explains how you can run virtual machines with Sun xVM VirtualBox 2.0 on a headless Ubuntu 8.04 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.

Linux How To Block Spam Before It Enters The Server (Postfix)
Post date: June 4, 2007, 18:06 Category: Security Views: 1089 Comments: 0
Tutorial quote: The last few weeks have seen a dramatic increase in spam (once again). Estimates say that spam makes now up for 80 - 90% of all emails, and many mail servers have difficulties in managing the additional load caused by the latest spam, and spam filters such as SpamAssassin do not recognize large parts of that spam as they did before. Fortunately, we can block a big amount of that spam at the MTA level, for example by using blacklists, running tests on the sender and recipient domains, etc. An additional benefit of doing this is that it lowers the load on the mail servers because the (resource-hungry) spamfilters have to look at less emails.

Post date: November 11, 2008, 05:11 Category: Installing Views: 1103 Comments: 0
Tutorial quote: In this HowTo I will describe how to prepare an Ubuntu 8.10 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.
