Oh yea, one more disclaimer: do to the invasive nature of this configuration; I am not responsible for your screwing up in any why shape or form. If you get caught it is your own fault. If you fry something (including a switch, router, hub, Ethernet card or motherboard), it is your own fault. Now that the lawyers have been appeased…

In Part I, I explained the basic model. This was a good warm up for the non-technical. Part II was quite a bit more challenging. It required light soldering as well as knowledge of the internals of a PC. Still, it was on a level that most should have been able to do with little or no difficulties. This model had the added advantage of being a bit more stealthy. The additional steps discussed here give you the ability to use this device on an actual network. This month's modifications are something a monkey with a bad attitude should be able to do, permitting they have access to the necessary areas.

For the final step in the Long-Ear Project you will need two Ethernet extension blocks (also known as "butt-blocks"), about two feet of small gauge speaker wire, and shrink tubing (for the wire). A butt-block is a little device used to join two cables together, much like a gender changer for a cable. Make sure to get the ones with female sockets on both ends.

The first step is to open the butt-blocks and cut the seventh and eighth wires. Then solder and shrink tube the speaker wire to the seven and eight wires coming into the block from the target computer. Next, solder and shrink tube the speaker wire to the seven and eight wires going to the listing post. Finally, place the butt-blocks on both sides of the hub or switch. Make sure the seventh and eighth wires are joined to the computer's side of the connectors - not the hub's. (It is potentially lethal to a hub to have a short between two lines.)

On a personal note: I used this configuration at work for a few months. It worked wonderfully until my co-worker decided to replace his CD-Rom. He was knowledgeable enough to notice the “custom modifications”. Unlike most shit-heads, he didn’t cry out to the boss for justice; he cried out for my help in teaching him how to do this to others. How he knew it was me I will never know…. It is one thing to be paranoid about your employer keeping tabs on you, it is entirely another to have your fellow co-works to worry about as well.
