Hi,
I need help regarding the raw sockets in wireless (802.11 or wifi) networking.
I want to send a packet using raw socket (on data-link-layer or layer 2) from STAtion to AP (Access Point).

Just for info: I am using madwifi as wifi-driver. So, I want to send packet of ath0 of one device to ath0 of other device. Of course using raw sockets....

I searched on the net extensively (believe me, i am doing it rigourously from last 5 days). But all I get is information regarding raw sockets in ethernet. The problem is, since packet structure of ethernet and wifi is different on data-link-layer, I may not use the code which is working perfectly for ethernet. "To use the ethernet code for wifi" is not that simple as it seems [at least for me ]. I am no more interested in ehternet raw sockets. I want exact information regarding raw sockets in wifi.

I am not sure whether there are any dedicated libraries for this or not?
I am not sure which libraries (or api) I have to use.


Can anyone of you would help me in this?

Yours Sincerely,

Did you ever work out this problem ?
I am basically looking at the same issue. I want to be able to inject 802.11 packets. So far everything I am seeing suguests that using raw sockets with wifi results in 802.3 ethernet packets

Well,

1. The code that works for ethernet works just perfect for wifi also. Provided, you put correct NIC (ath0 in case of madwifi driver).

2. You don't need to pay attention to MAC header of 802.11.

3. You just send an ethernet frame formulating, destination address, source address, type and the data correctly in memory.

4. It is the job of source and destination driver to "translate" if vice-versa.

5. On destination machine, you can see "802.11 MAC layer frame" on wireshark.

If you still need some help, revert back to me on this thread. I would be happy to help you.
