Setting up your Linux Firewall Distribution (Part 1)

Today I'm going to show you how to get start. In order to create a network you must design it in paper, visio, or any kind of drawing that shows your plan. If you don't create some kind of drawing your network will not be very efficient. This drawing was done Microsoft new version of visio which is still in beta it called visio 2010 and yes I do have a legit license for it. The way that I design this is setup as two networks instead of one. Reason why you may ask because Network A is does not have a speed restriction and not monitor. Network B is has a speed limit and it is monitor.


This is a basic drawing for this configuration. Remember the computer that your going to use must have at least two network cards. Let's break it down the red line named eth0 is your unfilter internet access which your trying to protect. eth1 is the green line which is your internal network which means that anything inside that network is protected. The blue line is optional, but I use it for a wireless connection which is separate from all the network. Note: This is also how you can create a DMZ (demilitarized zone - is a computer host or small network inserted as a "neutral zone" between a company's private network and the outside public network. It prevents outside users from getting direct access to a server that has company data.). When you create this kind of network is there more maintenance to do.

What is the IPCop firewall?



IPCop Firewall is a Linux firewall distribution geared towards home and SOHO (Small Office/Home Office) users. The IPCop interface is very user-friendly and task-based. IPCop offers the critical functionality of an expensive network appliance using stock, or even obsolete, hardware and OpenSource Software.

IPCop lets you take an old PC and convert it into an appliance that will.
 1. Secure your home network from the internet.
 2. Improve the performance of web browsers (by keeping frequently used information)
 All this functionality can be managed from a simple to use web interface, even updates and patches can be installed using a web browser.
 Remember IPCop works with most home networks and small office networks, dial up modems, cable modems, ADSL, Leased lines and ISDN. It also lets several PCs share connections to the internet. If you have an always on connection to can even use IPCop to protect your web and email servers. IPCop also has remote management meaning you can securely update and reconfigure your IPCop firewall from anywhere with an internet connection.

Learning Linux

Learning linux from the ground up is really a challenge. As you progress even more you start customizing your OS from how it starts and how it shutdown. As soon as you start on a Live CD your x server is pretty much either gnome or KDE. I mean it looks easy to do, but as soon as you start research how the x server it can get trick. My recommendation is to also learn the bash line or command prompt. if your good with the line commands then reconfiguring your computer shouldn't be a problem, but you just learn the GUI layer of it and not the line commands believe me your going to have hard time restoring your computer. As I ask people around they say linux is hard to install. The easiest way to partition your drive manually is like this. sda1 /home -- This is where you want to store all your data in case your linux gets corrupted. This space can be as big as you want sda2 /swap -- Linux is just like windows it needs it virtual space. The swap size depends on your physical ram.

DTS OS Enterprise

Well here are screen-shots of the OS images that I am making. The Desktop Environment is KDE The web browser is Firefox with a simple theme in place. Overall DTS OS Enterprise has two versions and it was made for especially for the acer aspire one netbooks. The OS should work with other computers since it is Linux. Some of the network icons are going to replace with custom icons.    Different Edition s Network Security Restoration Edition  File name: DTS-NS.iso File size: 200 - 300 MB The release date is going to be sometime in the late spring 2010.

Netwars Competition

The NetWars game is a collection of computer and network security challenges. It is designed to represent real-world security issues: their flaws and their resolutions. Each player can follow an independent path based on individual problem solving skills, technical skills, aptitude, and creativity. The game is played in a fun but safe environment using the technology that drives our lives every day. The game starts when a player downloads and starts a CD-ROM image on a PC or in a virtual environment such as VMware Player. The image contains a brief tutorial and the game's full instructions. The player must find a hidden key within the image that is downloaded and then uses that key to enter an online environment where knowledge of security vulnerabilities and their exploits can be turned into points. Upcoming Competitions   June 18-20, 2010 PST September 17-19, 2010 November 5-7, 2010 December 17-19, 2010 April 29 - May 1, 2011 Click Here to read more
