How To Configure ISP Mail Server With Virtual Users/Domain On Centos 4.5 Using Postfix, Dovecot, MySQL, phpMyAdmin, TLS/SSL
This tutorial describes how to set up a mail server where Postfix is
the SMTP service, and Dovecot provides IMAP and POP services. The users
are virtual and user information is stored in a MySQL database.
Installing MyDNS And The MyDNSConfig Control Panel On CentOS 5.1
In this tutorial I will describe how to install and configure MyDNS
and MyDNSConfig on CentOS 5.1. MyDNS is a DNS server that uses a MySQL
database as backend instead of configuration files like, for example,
Bind or djbdns. The advantage is that 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. A secondary
nameserver can be easily set up by installing a second instance of
MyDNS that accesses the same database or, to be more redundant, uses
the MySQL master / slave replication features to replicate the data to
the secondary nameserver.
Creating Encrypted FTP Backups With duplicity And ftplicity 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).
How To Make Your Xen-PAE Kernel Work With More Than 4GB RAM (Debian Etch With GRUB)
If you have a server with more than 4GB RAM and want to install a 32bit Debian Etch on it (following this tutorial: Debian Etch And Xen From The Debian Repository),
you’d expect the Xen-PAE kernel to see all your RAM because the Xen-PAE
kernel supports up to 64GB RAM. In fact, it recognizes only about 3.3GB
RAM due to a bug in the GRUB bootloader. This article explains how you
can fix GRUB so that all your RAM gets recognized.

How to configure Squid for two-factor authentication from WiKID
In this guide we will show how Squid can be configured to support
two-factor authentication from a WiKID server, allowing users to be
centrally authenticated, but their requests still distributed for
efficiency.
