levigross / scapy Goto Github PK

I have written a python program to transmit data of approximately 950 bytes in the RSNinfo field of a scapy Dot11 type 2 packet (data). It is also a beacon. I am doing this for experimental purposes, sorry. When i try to send it through sendp, I get the following traceback:

I really need to be able to do this for a project. Any help would be greatly appreciated.

Hi,

On behalf of the Scapy team, I would like to inform you that the development recently moved to github: http://github.com/secdev/scapy

In order to make things easier for the Scapy community, maybe you could consider either closing this repository, or make it a github fork.

Thanks,
Guillaume

I have written a small script that reads a cap/pcap file, chnages its source mac and destination mac and send it over the wireless network. The error is seen in "Python27\lib\site-packages\scapy\utils.py" file.

error logs:

Any help is highly appreciated.
