This how-to describes how to install and configure Dansguardian with multi-group filtering, Squid with NTLM auth, ipmasq, and dnsmasq to provide a full internet gateway solution for small to medium sized networks.

You can easily configure IPv6 Tunnel under Debian or Ubuntu Linux to browse IPv6 ready websites and use IPv6 utilities. If your ISP is not ready with IPv6 native transport, you can easily set IPv6 tunnel under Debian or Ubuntu Linux using tspc (tunnel setup protocol client). tspc provides a mean to configure a tunnel obtained from a tunnel server which is compliant to the tunnel setup protocol (TSP).

tspc: Debian / Ubuntu Linux Configure IPv6 Tunnel

Linux can be configured to log dmesg output to another system via network using syslog. It is done using kernel level networking stuff ia UDP port 514. There is module called netconsole which logs kernel printk messages over udp allowing debugging of problem where disk logging fails and serial consoles are impractical. Most modern distro has this netconsole as a built-in module. netconsole initializes immediately after NIC cards.

dar is a fast and easy command-line driven backup program which is efficient and reliable.
tripwire is a security tool which practically monitors files and directories and tells you when any change occurs.

WebVZ is one of the simplest and most powerful web management tools for OpenVZ. This tutorial shows how to install it on a Debian Etch system.

This document describes how to set up PHPlist on Fedora, CentOS, Ubuntu and Debian. This howto should also work for other distributions with little modifications. Taken from the phplist page: "phplist is an open-source newsletter manager. phplist is free to download, install and use, and is easy to integrate with any website. phplist is downloaded more than 10 000 times per month and is listed in the top open source projects for vitality score on Freshmeat."

In this HowTo I will describe how to prepare a Debian Etch 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.

This guide explains how to set up mod_geoip with lighttpd on a Debian Etch system. mod_geoip looks up the IP address of the client end user. 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.

This document describes how to set up TrueCrypt 5.1a on Debian Etch (GNOME). Taken from the TrueCrypt page: "TrueCrypt is a software system for establishing and maintaining an on-the-fly-encrypted volume (data storage device). On-the-fly encryption means that data are automatically encrypted or decrypted right before they are loaded or saved, without any user intervention. No data stored on an encrypted volume can be read (decrypted) without using the correct password/keyfile(s) or correct encryption keys. Entire file system is encrypted (e.g., file names, folder names, contents of every file, free space, meta data, etc)."

This mornings upgrade of Cacti on Etch wasn’t a very good one - it only displays

 Invalid PHP_SELF Path

Get back the old one with:

 sudo aptitude install cacti=0.8.6i-3.2

Then things should be back to normal. See also: Bug #479618 with the severity grave.

To say it with the words of Andreas Barth (one of the Debian release managers):

Etch is now frozen! Wheeeeeee!!!
