Setting up a firewall for IPtables can be rather difficult, especially if its your first time. A firewall is something you need to have, whether you are just trying to keep hackers
out, or trying to meet a requirement such as PCI compliance, or HIIPA compliance. Luckily the folks at rfxnetworks, created a CLI based configuration for IPtables.
First, download the firewall software at this URL:
http://www.rfxn.com/downloads/apf-current.tar.gz
Untar it then, run install.sh. Now you have a firewall installed. That only took a minute, so for the other 14 minutes, we are going to configure it. After you ran install.sh,
it told you what ports you have currently open. So, now were going to edit the config file. The nice thing about apf is it has common firewall rules already setup.
For this example we are just going to change a couple configuration options, set the ports we want open, and setup ACL’s. For this example I will assume you are working with a
mutli-purpose server, which includes a web server. If you have a different type of server you are securing you may want to setup your firewall a little differently. And this firewall will run on top of an existing Linux system, and not be a stand alone type firewall that just filters packets.

How To Configure The AIDE (Advanced Intrusion Detection Environment)
File Integrity Scanner For Your Website
A file integrity scanner is something you need to have. Imagine a
hacker placing a backdoor on your web site, or changing your order form
to email him a copy of everyone’s credit card while leaving it appear to
be functionally normally. By setting up daily reporting, this
notifies you within, at most, 24 hours of when any file was changed,
added, or removed. It also helps establish an audit trail in the event
your site is compromised. These instructions are designed for an
end user, where you don’t need to have root access, to implement and
assumes your server has the aide binary installed. Most hosts will have
this installed already, or will install it for you upon request.

Caching With Apache’s mod_cache On Ubuntu 10.04
This article explains how you can cache your web site contents with
Apache’s mod_cache on Ubuntu 10.04. If you have a
high-traffic dynamic web site that generates lots of database queries on
each request, you can decrease the server load dramatically by caching
your content for a few minutes or more (that depends on how often you
update your content).

Installing A Multiserver Setup With Dedicated Web, Email, DNS And
MySQL Database Servers On Debian 5.0 With ISPConfig 3
This tutorial describes the installation of an ISPConfig 3
multiserver setup with dedicated web, email, database and two DNS
servers all managed trough a single ISPConfig 3 control panel. The setup
described below uses five servers and can be extended easily to to a
higher number of servers by just adding more servers. E.g. if you want
to have two mailservers, do the setup steps from chapter 2 on both of
these servers. If you want to set up more web servers, then install
ISPConfig on all other web servers in expert mode except of the first
one.

Installing And Using OpenVZ On Ubuntu 10.04
In this HowTo I will describe how to prepare an Ubuntu 10.04 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.

How To Set Up A USB-Over-IP Server And Client With Ubuntu 10.04
How To Set Up A USB-Over-IP Server And Client With Ubuntu 10.04
This tutorial shows how to set up a USB-over-IP server with Ubuntu
10.04 as well as a USB-over-IP client (also running Ubuntu 10.04). The USB/IP Project
aims to develop a general USB device sharing system over IP network. To
share USB devices between computers with their full functionality,
USB/IP encapsulates “USB I/O messages” into TCP/IP payloads and
transmits them between computers. USB-over-IP can be useful for virtual
machines, for example, that don’t have access to the host system’s
hardware – USB-over-IP allows virtual machines to use remote USB
devices.

Epidermis theme manager
Epidermis combines wallpaper, GTK, metacity, icon, splash, usplash, cursor, grub and Xsplash themes in one GUI program for the GNOME desktop.
Epidermis manages ‘packages’ called pigments and downloads them from a ‘repository’. Pigments can be any type of installable customisation: current pigment types include wallpaper, icon set, GTK theme, metacity theme, gnome splash, usplash, mouse cursors, grub theme, GDM theme and finally ‘skin’ which links to one pigment of every type. This allows several skins to share components, similar to how programs share dependancies, hence copying the repository functionality.

Howto Install OSS4 in ubuntu 10.04 (Lucid) for better sound quality
After upgrading to Ubuntu 10.4 LTS, I was happy to notice that audio in all applications (including Skype) was finally working perfectly! However, I was less happy to notice that Pulseaudio was using quite a lot of CPU-time, and that the sound quality was absolutely awful… So I decided to give OSS4 a try. After some googling, installing a few packages and some minor configuration, OSS4 was up and running, and I must admit the improvement in sound quality is rather significant!

Configuring Conky The (Very) Easy Way
Conky, the amazingly versatile and useful Linux desktop application, has a bit of a reputation. It’s clearly a great app, but getting it configured can be a serious pain. Changing anything about it has always required digging through a long text file and editing cryptic lines like ${offset 240}${time %a, } ${color }${time %e %B %G}. As many people don’t have the patience to dig through manuals to find out what all that means, Conky’s popularity has been somewhat limited. Lucky for us, there’s now an easier way to configure it. A MUCH easier way – ConkyWizard.
