Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (CentOS 6.2 x86_64)

This document describes how to install a Postfix mail server 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, 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. Passwords are stored in encrypted
form in the database. In addition to that, this
tutorial covers the installation of Amavisd, SpamAssassin, ClamAV and SquirrelMail.

Virtualization With Xen On CentOS 6.2 (x86_64) (Paravirtualization & Hardware Virtualization)

This tutorial provides step-by-step instructions on how to install Xen (version 4.1.2) on a CentOS 6.2 (x86_64) system. Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD), so called “virtual machines” or domUs, under a host operating system (dom0).
Using Xen you can separate your applications into different virtual
machines that are totally independent from each other, but still use the same hardware.

SQUID Proxy On RHEL5/CentOS – Everything That You Should Know About [Part 1]

The main feature or duty of a proxy server could be a gateway that receives
HTTP requests from clients and forwards the request to the destination and relays the answer back to the requestor. Squid is most popular open-source software that brings this to us. It
also has
some excellent features for doing something else such as web access
controlling,
bandwidth controlling, restriction policies, and content caching and
filtering. Actually people install SQUID to pursuit 2 goals: first
reduce the bandwidth
charges by content caching and second for restricting access to
particular
contents. The following guide explains advantages of using Squid and will show you how to
install, configure, control, and maintain the Squid Proxy Server on
RHEL5 and CentOS Linux.

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.

which one).

Serving CGI Scripts With Nginx On CentOS 6.0

This tutorial shows how you can serve CGI scripts (Perl scripts) with
nginx on CentOS 6.0. While nginx itself does not serve CGI, there are
several ways to work around this. I will outline two solutions: the
first is to proxy requests for CGI scripts to Thttpd, a small web server
that has CGI support, while the second solution uses a CGI wrapper to
serve CGI scripts.

This article is about how to use the Pinta graphical editor to edit pictures and covers some of its most important features. Pinta is a lightweight image editor for Linux and is far more easier
to handle than Gimp but still has a large variety of tools and features
to use. It can be used for quick editing like resizing images or
adjusting the colours of photographs, but also for more professional
tasks which depend on layered images and more. It is a good mixture
between MS Paint and professional image editing tools and is
recommendable for most purposes of image-editing-everyday-use.

Lessfs 1.5 On CentOS 5

For this HowTo I used a VirtualBox with CentOS 5.7 x86_64. I attached a
separate 20GB Data drive mounted to /data. This will hold the lessfs DB and data.
The lessfs mountpoint I put at /lessfs. This is a very basic setup, just to get it running. There is plenty of tuning
to be done based on volume size, file types, and compression choices. The latest lessfs required more recent versions of fuse and tokyocabinet than
was in the CentOS repository, so I chose to install most of this from source.

This small HOWTO will show you how to set up a small virtual machine to speed
up and secure your home / small enterprise web surfing network using CentOS 6,
Squid 3.1 and QuintoLabs Content Security 1.4 applications deployed in a
VMware Virtual Player running on Windows 7 x64 as a host operating system.
This howto is targeted at novice users and may sometimes seem too thorough for
more advanced gurus.

POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the 64-bit
version of CentOS 6.0, but should apply to the 32-bit version with very
little modifications as well. In the end you should have a system that
works reliably, and if you like you can install the free webhosting
control panel ISPConfig 2 (i.e., ISPConfig runs on it out of the box).

Virtualization With KVM On A CentOS 6.0 Server

This guide explains how you can install and use KVM for creating and
running virtual machines on a CentOS 6.0 server. I will show how to
create image-based virtual machines and also virtual machines that use a
logical volume (LVM). KVM is short for Kernel-based Virtual Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware virtualization, e.g. Intel VT or AMD-V.

Xtables-Addons On Centos 6 & Iptables GeoIP Filtering

This tutorial will explain how to install aditional modules for the
kernel to use with iptables rules sets (netfilter modules).

contains extensions that were not, or are not yet, accepted in the main
kernel/iptables packages.
Xtables-addons is different from patch-o-matic in that you do not have
to patch or recompile the kernel.
