Getting access point information using Scapy

[thomas1984]

Hi

I have a question about a library available for Python: Scapy (www.secdev.org/projects/scapy/). This library offers a variety of things but I am interested in how it interacts with wireless networks.

I have read countless tutorials and documentation on it but I can't figure out the following:

-- How to sniff for wireless networks (listen to beacon frames for passive scanning)
-- How to sniff for wireless networks (transmitting probe request frames and then listening for the response - active scanning)
The above two points are to detect any wireless networks within the range of the wireless adapter (basically I want a list of networks)

-- I also need to know how to obtain a list of Access points wihtin range PER network.

-- I then want to know the signal strength of each ACCESS POINT per network (in other words each wireless network may have more than one access point - signal strength as a percentage)

-- Other information about each and every access point such as (access point name, access point MAC, time of arrival packets, time of transmission packet, HOW LONG A PACKET TOOK TO REACH ME (as accurate as possible, not seconds - perhaps milliseconds?)

-- And any other information about the access points or networks

I need to know how to achieve this because I ultimately need to know HOW FAR the access point is from me (leave me to figure this out, it should be possible with the above information)... Please suggest and advise and help me figure the above out

Does Anyone out there use this? know how to do this? can help me? PLEASE... I have been stuck on this for a very long time and I am desperate for some help. An ideal answer would be lines of code with comments please.

- THANK YOU SO MUCH :)

There is a lot of good information about scapy out there, and I can't claim to be an expert. With regards to discovering access points, you may want to check out this link: http://www.devx.com/security/Article/34741/1954

Most of your questions require in-depth knowledge of 802.11x in order to give scapy the correct parameters. I would suggests some careful Googling on each particular point, and use that to build you feature-set.

your problem is same as me...please help
