tracking down ap's

bigsi · 07-05-2004

Hello - I'm very new at using NS so I need help. I am trying to secure our LAN and want to make sure that none of our users are running AP's from their wireless capable notebooks. I have found one such AP - but have now idea where it is located physically i.e. what user is running it. Any help would be greatly appreciated.

Use the signal level meter in conjunction with a directional antenna and triangulate.

You know this is going to turn into a step-by-step walk-thru, don't you?

No, it's not. At least not from me, because I haven't the time or the inclination this week.

I actually started writing a "How to Triangulate" article last year. It was geared toward the SysAdmin who knows networks like the back of his hand, but knows jack about RF. When it was about 75% done, the SD chip it was on suddenly died. I had actually started rewriting it when Chris asked me to help with WDDD. The book then took all of my writing attention for several months.

Ok, I'll bite.

Step 1. Find a computer that has a wireless network with an external antenna connector that uses the same frequency as the AP you are looking for. If you do not have computer that runs off of batteries, you will need a R.B.F'n long ass extension cord or a generator.

Step 2.Find a directional antenna that uses the approperate frequency.

Step 3. This is the tough one. You will need either A. A pigtail that has a the same connector as both your antenna and the wireless network card, or B. a pigtail that has the same connector as your wireless network card and the cable that attaches the pigtail to the antenna.

Step 4. If you have not already done so, install and start NetStumbler with your wireless network card installed in the computer and your directional antenna attached to the wireless card using one or more of the necessary cables from step 3.

Step 5. In the left plane, find offending AP by frequency or ssid, and navigate down to it untill you get this graphical signal strength display.

Step 6. Aim the directional antenna until you receive the strongest signal strength from the bogie.

Step 7. Walk in the direction that the directional antenna is pointing.

Step 8. Repeat steps 6 through 7 until you find the offending AP. If there is an obstruction in the way, walk around, through, or over it.

Step 9. Smash the offending AP with a R.B.F'n hammer.

If you can not do this, I'll send Tommy over to hit you on the head with a tack hammer, because YOU ARE A RETARD!!!

This can also be calculated with 3 omnidirectional antennas, but if you read my above guide, you probably don't have the necessary math skills to do that. Even I don't.
