Cisco AIR-AP1131AG-A-K9

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.

Giving a PIX firewall a new lease on life

Buying networking equipment off of Ebay can be one of the most rewarding and frustrating challenges you may ever face. Of course, being able to identify and fix issues with newly purchased hardware may mean the difference between having purchased a $500 firewall for $11 and some parts versus buying another piece of crap for $11 that will live out its life in the back of the parts closet.   In this article, I’ll cover how to replace the power supply to a Cisco PIX 506E firewall with a standard computer power supply.

Arduino: Basic Network Temp and Humidity monitor

by on Aug.23, 2012, under Microcontrollers, Networking

I don’t know why I can’t flip this image. It’s cursed.

The (albeit crooked) image above is a basic environmental monitor I built for the server rack that I keep my house’s servers in. This project features network connectivity via an Arduino Ethernet shield, an HTF3223 humidity sensor, a TMP36 temperature sensor and a Sparkfun serial LCD for a decent monitoring station that is self-reliant.  Read more for build details and the code to get it all working.

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…)

pfSense Logo

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.

In this post, I will review a recently acquired WD TV Live Plus purchased from Microcenter for around $100.  The quest was to find a media player solution that could read media from network shares and play them with minimal fuss.  Since this is going to be attached to the primary TV, it has to be “Girlfriend Approved” and easy to use.  I believe that the WD TV Live Plus fits this requirement adequately however the installation of the device could be easier.  Once done, the device is wonderful.  Read the full review after the break.

Networking: Duplicating Drops in structured wiring

Networking

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.
