Networking: Bringing IPv6 into your network using pfSense

by on Dec.01, 2011, under How-To's, Networking, Software

Hurricane Electric, PfSense and IPv6The Internet as we know it is undergoing a significant change.  With the last IPv4 addresses being allocated out, the Internet has officially run out of address space.  IPv6 is the next-generation IP addressing system that aims to resolve this issue however the changes proposed are drastically different than the current IP schema currently in place and for most is quite a daunting task to switch. In this post, we will cover some basic IPv6 information and some fundamental differences between v4 and v6 (aside from tons of IPs), and finally we will build out a pfSense firewall with IPv6 using pfSense and a free IPv6 tunnel provided by Hurricane Electric. Read more to get started on the cutting-edge of Internet infrastructure. (continue reading…)

Networking: Installing and configuring pfSense Embedded

After publishing the last post on networking and the security series, I felt it was necessary to go ahead and publish a piece on building a custom router.  I have been a fan of pfSense for the past four years and swear by it. It has the ease of use of a commercial GUI-driven router and unrivaled flexibility limited only by the hardware it is installed on.  In this howto article, we will cover installing pfSense on an embedded platform and initial configuration for getting your router up and running.

CVS Netbook Revisited

by on Jul.25, 2011, under Embedded devices, Hardware, How-To's, Linux, Software

A few months ago, I posted a hardware teardown of the CVS Sylvania Netbook pictured above. After working with it and performing a lot of research on it, I promised a follow up article, and here it is.  To sum it all up, with a bit of modification to the software, a spare SD card and a lot of patience, you can actually turn this thing into a somewhat useful Linux device.  There’s also some improvements and suggestions to be had for improving the Windows CE side of things should you decide to continue using it in its default state.

Building Snort and Nessus – Ubuntu IDS Part 3

by on May.20, 2011, under Hardware, How-To's, Linux, Security, Software

 

In this final article in the three part Ubuntu IDS series, we will go over installing, compiling and configuring Snort and Nessus on our new IDS device.  We will use Snort to analyze traffic as seen by the IDS and we will use Nessus to perform vulnerability testing on the network. The process for installing Snort will also cover installing SnortReport provided by Symmetrix Technologies so we can translate Snort’s cryptic messages into a more readable format that we can take action on.  Read on as we wrap up the installation and finish our IDS device.

Setting up bonding networking -Ubuntu IDS Part 2

by on May.04, 2011, under Hardware, How-To's, Linux, Security, Software

In an earlier article, I demonstrated how you can build a passive monitoring device for an Ethernet network as the first part to a three part project to build a home IDS device.  In this article, the second in the series, I will describe how to set up the networking for an IDS using the passive tap that I built earlier.This setup will involve using a technique called bonding to take two physical interfaces and bond them together, creating a logical interface that we can use for Snort.  This article will also explain where is the best location to place the tap and what you can expect to see once the networking is set up using common Linux utilities like tcpdump.

Build a Passive Ethernet Tap – Ubuntu IDS Part 1

One of the things that the GCIA study has taught me is that being able to monitor the network your computer is on is a critical necessity to maintaining a secure network. Corporate environments can set up IDS devices to monitor traffic however monitoring doesn’t work unless you have proper connectivity to what you want to monitor. Unfortunately, most of us don’t have central wiring in our house and expensive managed switches that can set up span sessions with which to monitor traffic in transit.  In this HOWTO, I will cover how to build your own monitoring connection that you can use on your own network to monitor traffic without breaking the bank. This article is first in a three part series on how to build your own home IDS for monitoring your network traffic. Look for the other two sections soon!

Installing Minecraft Server in Ubuntu Server

by on Jan.09, 2011, under How-To's, Linux, Software

Minecraft and Ubuntu logosOk, I’ll admit it.  I’ve been caught by the Minecraft bug.  It bit me hard and of course I learned rather quickly that there is a problem with using two laptops to play Minecraft on and that is that it’s a pain in the posterior to move your save games around.  In this article, I will be covering how to install Minecraft Server on a new installation of Ubuntu 9.04LTS.  These instructions will work for all current versions of Ubuntu, so if you’re using something newer or something older, these instructions should get you up and running in no time.

by on May.15, 2010, under Embedded devices, Linux, Product Reviews, Software

While writing up the review for the Samsung Moment versus the Palm Pre, I happened to find out that Sprint has now released Android 2.1 (Eclair) for the Moment.  Guess now I have to start over again, but the up side is that this is a very significant update from Samsung’s initial release, Android 1.5.

You can download the update from Sprint at http://shop.sprint.com/en/software_downloads/pda_smartphone/samsung_moment.shtml

Please note: According to the instructions available at the link above, you will need to use a Windows PC to apply the update to your phone.  I will be posting a mirror shortly and it will show up in the “Download Files” page at the top of this page.

Web: Stupid HTML trick to get past content filters

by on May.02, 2010, under How-To's, Miscellaneous, Networking, Software

I know it’s been a while since I posted, and I do apologize.  Life has definitely not been kind to me in the regards of time however I have not forgotten anything. I have two major posts coming up hopefully within the next week, however here’s a quick article about a trick I discovered while working on a project with a friend.  The project was to see if their content filter could be broken in their chat application andthrough a little bit of HTML know-how and some PHP code, I was able to crank out a generator to do just that.  Read more to find out the details.

Games: Half-life “mad-scientist” glitch found and overcome

When I’m not wielding a soldering iron or slinging parts around my workbench, I like to get my frag on just like many other gamers out there.  So imagine my sadness when in the midst of the heated battle to protect the planet from the likes of an invading alien force in the original Half-life, my pursuit of alien destruction came to a screeching halt by way of a serious game glitch. This glitch occurred on the map called “Questionable Ethics” and was readily reproducible.  Read more for details about the game glitch and a video that shows how you can get past the glitch and continue on.
