Debian Virtual Users And Domains With Postfix, Courier And MySQL (+ SMTP-AUTH, Quota, SpamAssassin, ClamAV)
Post date: October 9, 2005, 14:10 Category: Network Views: 213
Tutorial quote: 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.

The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I'll show how to patch your Postfix appropriately). Passwords are stored in encrypted 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 Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses.
Unix+clones Running A MySQL-Based DNS Server: MyDNS
Post date: January 23, 2006, 10:01 Category: Network Views: 32
Tutorial quote: In this tutorial I will describe how to install and configure MyDNS, a DNS server that uses a MySQL database as backend instead of configuration files like, for example, Bind or djbdns. This has the advantage that you can easily use web-based frontends to administrate your DNS records. You could even write your own frontend, e.g. using PHP, to interact with the MyDNS database. MyDNS simply reads the records from the database, and it does not have to be restarted/reloaded when DNS records change or zones are created/edited/deleted! This is a major advantage.
Linux Optimizing Linux filesystems
Post date: April 12, 2005, 03:04 Category: Benchmarks Views: 118
Tutorial quote: Last time we introduced a few common Linux filesystems and examined their features. If you've already installed Linux, your partitions are already set up and configured with particular filesystems, but you may decide you want to modify this configuration. What's the best way to begin?
Linux Optimizing Desktop Performance, Part III
Post date: May 31, 2005, 10:05 Category: Optimizing Views: 144
Tutorial quote: For desktop and laptop users who want a fast-booting operating system, getting rid of services you do not need can appear to improve performance. Obviously, if you are new to Linux, though, you probably do not know which processes you can get rid of safely nor how to stop them and keep them from restarting at boot time.
Linux Optimizing Desktop Performance, Part I
Post date: May 16, 2005, 19:05 Category: Optimizing Views: 76
Tutorial quote: If you have complained about the speed of OpenOffice.org or Firefox or about the amount of time Linux takes to boot up, this set of optimizations should change your perception. Linux can boot up quickly, the word processor can spring open and the browser can fly. So, let's make these adjustments so your computer can fly.
Linux Performance Tools for Optimizing Linux: Process-Specific CPU
Post date: June 1, 2005, 03:06 Category: Optimizing Views: 140
Tutorial quote: The tools to analyze the performance of applications are varied and have existed in one form or another since the early days of UNIX. It is critical to understand how an application is interacting with the operating system, CPU, and memory system to understand its performance. This chapter will help you understand where the bottleneck in your system is occuring, and how to fix it.

Tutorial quote: A short, but detailed howto about installing ProFTPD with all the bells and whistles on Gentoo.
Linux Optimizing Desktop Performance, Part II
Post date: May 24, 2005, 14:05 Category: Optimizing Views: 135
Tutorial quote: As we discussed in last week's article, for most of its existence, people have distributed Linux as a workstation or a server rather than as a desktop. The default workstation that evolved has existed mostly for use by developers. So, when you install a Linux distribution with a graphical interface, it generally looks like what a developer might want. In addition, it performs similar to how many UNIX workstations work, which can seem slow.

In this article, we continue to look at the Linux desktop in a different light. Here, we think of it as a computer system with a fast interface that we can optimize for the knowledge worker and consumer.
Unix+clones Mysql Cluster: Two webserver setup (three servers required for true redundancy)
Post date: July 11, 2005, 08:07 Category: Network Views: 80
Tutorial quote: This HOWTO was designed for a classic setup of two servers behind a loadbalancer. The aim is to have true redundancy - either server can be unplugged and yet the site will remain up.
Gentoo Remote Backup Using Flexbackup and SSH
Post date: December 31, 2005, 10:12 Category: Network Views: 97
Tutorial quote: I have a server running Gentoo Linux which hosts a Subversion repository, a vpopmail and qmail system, a MySql database and more. I’m going to make a backup copy of the data on this machine in the event that I need to rebuild this server. I have chosen Flexbackup to perform this task.
