It might not look like much, but the switch used as this feature image has more to offer than one would think judging by appearances. In this article, we will be converting a “stupid” switch into a “smart” switch for the purposes of controlling a connected GE Light Bulb over Z-wave and discuss why you’d want to look for a stupid switch for smart devices in the first place.

Everyone knows that I love a bargain. That love for bargains is intensified any time networking gear is involved. Imagine my excitement when I found a bunch of the above pictured Cisco access points on Ebay for around $8 a pop because the lid won’t stay on. Unfortunately, my excitement was tempered a bit when I found out that these were designed to work with a controller and weren’t stand alone units. Undeterred by this disappointment, I researched and found a way to get these things to operate on their own as standalone units and freed them from the hive mind! In this article, we will cover converting the Cisco AIR-AP1131AG-A-K9 from “Lightweight”(controller-based) to “Autonomous”(standalone) and will even cover how to put them back in “Lightweight” mode if you want later on.
Quite some time ago, I posted an article on how to build a basic Minecraft Server which served to get you up and off the ground with multiplayer gameplay. It’s been two years since that article was posted and there have been so many advances in the Minecraft Server realm from administration changes (now you have a fancy GUI) to core game changes that allow for the modification for just about everything gameplay related. Popular alternative servers (Bukkit, Tekkit, Feed The Beast, etc..) allow for mods to be used which can drastically expand your Minecraft experience. This howto will detail the process going from a basic Debian server installation to a fully fledged vanilla Minecraft server with a browseable map. Read on for the full article, it’s pretty long but we have a lot to cover. (continue reading…)
Have a giant Arduino powered killbot, but can’t fancy being right next to it when you unleash it on the unsuspecting populace? Want to change the mood-lights in your dorm without having to get up off the couch? Why not use IR remote controls to do the walking for you? In this article, I will be covering how to use the IRremote Library written by Ken Shirriff for the Arduino to control a seven segment display as a proof of concept. Killbot not included.
The 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…)
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.
Structured wiring in businesses and the enterprise are as expected as the sun shining and a regular paycheck, however in the home a structured wiring solution can be an unexpected gift from the Gods of Ethernet. While structured wiring in an apartment complex is usually done central to a utility closet or shelf, sometimes the central point isn’t always convenient for your router or you find yourself needing to run multiple networks. In this tutorial, I will show you how to turn one structured wiring drop into two drops for carrying two different network segments, something that can be of benefit should you ever need it.

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.
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.
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.
