Vlogger is a little tool with which you can write lighttpd logs broken down by virtual hosts and days. With vlogger, we need to put just one accesslog.filename directive into our global lighttpd configuration, and it will write access logs for each virtual host and day. Therefore, you do not have to split lighttpd's overall access log into access logs for each virtual host each day, and you do not have to configure lighttpd to write one access log per virtual host (which could make you run out of file descriptors very fast). At the end of this tutorial I will show you how to use webalizer to create statistics from the lighttpd access logs.
djbdns is a very secure suite of DNS tools that consists out of multiple parts: dnscache, a DNS cache that can be used in /etc/resolv.conf instead of your ISP's name servers and that tries to sort out wrong (malicious) DNS answers; axfrdns, a service that runs on the master DNS server and to which the slaves connect for zone transfers; and tinydns, the actual DNS server, a very secure replacement for BIND.
Bazaar is a distributed version control system (VCS) available under the GPL; it is similar to Subversion (svn). Bazaar is sponsored by Canonical, Ltd., the company that develops the Ubuntu (GNU)Linux distribution, and therefore the Ubuntu project is the most prominent user of Bazaar.

This tutorial shows how to install and use alterMIME. alterMIME is a tool that can automatically add a disclaimer to emails. In this article I will explain how to install it as a Postfix filter on Debian Etch.
When you rent a dedicated server nowadays, almost all providers give you FTP backup space for your server on one of the provider's backup systems. This tutorial shows how you can use duplicity and ftplicity to create encrypted (so that nobody with access to the backup server can read sensitive data in your backups) backups on the provider's remote backup server over FTP. ftplicity is a duplicity wrapper script (provided by the German computer magazine c't) that allows us to use duplicity without interaction (i.e., you do not have to type in any passwords).
This guide explains how to set up software RAID1 on an already running Debian Etch system. The GRUB bootloader will be configured in such a way that the system will still be able to boot if one of the hard drives fails (no matter which one).

Debian-Installer Loader is a Debian Etch installer for Windows which adds an entry to the boot menu that allows you to start the Debian installation. Unlike the Ubuntu installation with Wubi, real Debian partitions are created during the installation. In the end, you have a dual-boot system (Windows/Debian).
This document describes how to set up Amanda (The Advanced Maryland Automatic Network Disk Archiver) on Debian Etch. For this tutorial I chose Ubuntu v7.04 as a backup-client. The resulting system provides a flexible backup system with many features. It will be able to back up multiple hosts via network to various devices. I chose the disk based backup for this howto.

Sometimes I just gotta wonder about GNU/Linux and wi-fi...Maybe you can help.
This guide shows how to install and configure Smokeping on Debian Etch to monitor network latency. From the Smokeping web site: "SmokePing is a deluxe latency measurement tool. It can measure, store and display latency, latency distribution and packet loss. SmokePing uses RRDtool to maintain a longterm data-store and to draw pretty graphs, giving up to the minute information on the state of each network connection."
This tutorial describes two ways how to give users chrooted SSH access. With this setup, you can give your users shell access without having to fear that they can see your whole system. Your users will be jailed in a specific directory which they will not be able to break out of. The users will also be able to use SFTP in their chroot jails.
This document describes how to integrate ASSP (Anti-Spam SMTP Proxy) with embedded ClamAV into a mail server based on Postfix featuring virtual users and domains, i.e. users and domains that are in a MySQL database.

This article shows how you can build your own video community using lighttpd with its mod_flv_streaming module (for streaming .flv videos, the format used by most major video communities such as YouTube) and its mod_secdownload module (for preventing hotlinking of the videos). I will use FlowPlayer as the video player, a free Flash video player with support for lighttpd's mod_flv_streaming module. I will also show how you can encode videos (.mp4 .mov .mpg .3gp .mpeg .wmv .avi) to the FLV format supported by Adobe Flash.

If you want a really good site to learn Debian administration, you really need to check out Debian Administration.
This article describes how to integrate DSPAM with embedded ClamAV into a mail server based on Postfix featuring virtual users and domains, i.e. users and domains that are in a MySQL database. DSPAM is a scalable and open-source content-based spam filter. The setup shown here is suitable for Debian Etch servers.
Lighttpd is a secure, fast, standards-compliant web server designed for speed-critical environments. This tutorial shows how you can install Lighttpd on a Debian Etch server with PHP5 support (through FastCGI) and MySQL support.
Zabbix is a solution for monitoring applications, networks, and servers. With Zabbix, you can monitor multiple servers at a time, using a Zabbix server that comes with a web interface (that is used to configure Zabbix and holds the graphs of your systems) and Zabbix agents that are installed on the systems to be monitored. The Zabbix agents deliver the desired data to the Zabbix server. This tutorial shows how you can install the Zabbix server and agent on a Debian Etch system.
