Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 8.04 LTS)

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 8.04 LTS)

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. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.

HowTo Compile rTorrent From SVN In Ubuntu 8.04 Hardy Heron

HowTo Compile rTorrent From SVN In Ubuntu 8.04 Hardy Heron

Torrent is a great way to transfer large files very quickly. However most torrent clients are gui based and have quite some impact on system resources (e.g. Azureus). rTorrent is a lightweight client running from the terminal. Being able to run it in a screen session (also upon boot) makes it ideal to also control it from a remote location.

Installing mod_geoip For Lighttpd On Debian Etch

Installing mod_geoip for Lighttpd On Debian Etch

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. If you've compiled lighttpd yourself, then the second way is for you: it shows how to build mod_geoip.so for your lighttpd version.

Encrypted Root LVM

Encrypted Root LVM

This tutorial deals only with how to add an extra encrypted physical volume to a volume group pool containing other encrypted physical volumes. This is typical scenario if, at first, you have set up your encryption at a physical partition level (/dev/sdaX where X is the a number of your partition), then you setup your LVM on top of the encrypted partition. If at some later time you want to add another partition in your volume group, you will also want to have it encrypted in order to maintain the same level of security.

Protect Your Files With TrueCrypt 5.1a On Debian Etch (GNOME)

Protect Your Files With TrueCrypt 5.1a On Debian Etch (GNOME)

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)."
