Installing Softaculous on Cpanel and Direct Admin
Posted by Richard in cPanel on January 9, 2011 with No Comments
In this article I will explain how to install Softaculous on systems running Cpanel or Direct Admin. Softaculous is an Auto Installer that has numerous scripts. Softaculous is suited for Web Hosting companies. Although similar to others, softaculous tends to be faster, since it installs the scripts in a single step. Rather then a few like Fantastico.
The installation process is very simple and straightforward as seen below.
IPTables – IP Protocols and Ports (Part 4)
Posted by Richard in Uncategorized on January 1, 2011 with No Comments
Welcome back once again to this the final article in which I explain the basics of IPtables. This post will be focused on filtering like the last article. But this time I will explain how to filter using TCP/IP protocols as well as ports. Before we dive into examples, it’s important to understand how protocols and port numbers work together. As well as some standard protocol/ports some common services use. Note: I will cover just a very basic overview.
How to use IPTables – Ports and MAC filtering (Part 3)

In the last post I walked you through a script to create a stateful packet inspection firewall. Which allowed out-going traffic to the internet, but which blocked in-coming traffic. In this part I’m going to explain how to open up specific ports (or holes). To allow certain types of internet traffic successfully through.
As with the earlier articles, there are a few basic parts that rules can be filtered for. These four parts are as follows:
- IP Addresses: a single address (94.76.240.128), or multiple addresses in a range (94.76.240.128-150)
- Interface: eth1,ppp0,wlan0 (these are usually names of physical network ports on your computer)
- Ports: a single port (http 80) or a range of ports
- Protocols: icmp, tcp, udp, all
(for a detailed description, see my first article)
How to use IPTables – Part 2

Welcome back to this the second part of the discussion about IPtables, if you missed the first part you can find it here. As mentioned previously, I plan to get into some basic usage and hands-on practice. A few notes before we get started. Firstly: IPtables from the CLI requires root or administrative access for the majority of commands. Second: for these demonstrations, we will be erasing all current existing entries.
I highly recommend that these be practiced on a home machine where you have admin rights and aren’t using IPtables as your active firewall. Since deleting the configuration will leave the computer vulnerable to attack. Under no circumstances should this be practiced on a live production network (i.e at work). Myself nor GBServers will be held responsible for any possible damages by ignoring these suggestions. I’d go as far as suggesting: unplugging your computer from the internet. You can practice with computers on your home network. You don’t necessarily need to be connected to the internet.

How to use IPTables. What is IPTables? - Part 1
Many people may not be aware but Linux and many unix like operating systems have a firewall built into it, which is most commonly known as iptables. Unlike most consumer-based firewalls, iptables is CLI or command line interface based. Although there are a variety of point and click graphical interfaces available. Most of the time they hide most of the functionality of the CLI. So in my opinion it’s best to learn how to operate iptables via the command line rather than rely on a GUI. At first it may seem difficult but with practice, it will become much easier.
Before I start; I’d like to note that while writing this article. It ended up quite long. I will break it down into multiple blog entries over the course of the month. So the majority of content can be kept. As well as you, the reader hopefully won’t get overwhelmed.
This initial article will cover basic background information. Which will be important for understanding the future material.
Helpful network/system utilities

In this article I will explain a few common and useful utilities for network and operating systems in general.
Netstat
The main purpose of netstat is to give a quick general overview of the connections the system is using. Plus information such as, the protocol typically TCP/UDP or the current status state.

How to build a rack server

How to build a rack server
If you have ever built or upgraded a personal computer. Then building a rack mounted server is very similar with some minor differences as seen in this article. One of the more important aspects being the hardware that you ultimately decide to use, which can affect the overall performance of the server. This post will show you the basic how-to of building a server from scratch. If you use a bare bones unit, much of the hardware should be included in the kit.
Hardware Installation
Processor
The processor is easily installed. Look at the bottom of the CPU. You’ll see at least one edge (possibly two) with pins missing. It will look like a diagonal. Which will match the socket for the cpu. If it does not seem to fit, do not force it. You will bend or break pins. Double check that it is orientated correctly, so the pins line up.

This basic tutorial will show you how to set up a CentOS5.x (CentOS5.5).
Once you have completed this tutorial. You should hopefully have a basic up and running system. I would like to point out that this is not a concrete or the only method of doing it. You may find slight differences depending on your server specs or different versions of the various services.
