I have set up scapy on linux (raspian on RPI) for sniffing WiFi packets using WiFi adapter (b/g) in monitor mode. I am not sure if scapy by default hops on all the channels of the b/g protocol, or sticks to just one of them.

I'd like to have the capability to sniff different channels by hopping on to them, and to have capability to configure the dwell time on each channel, all using snapy. Can some one help me how to do that? Thanks a lot.

One way would be to use a bash script with iwconfig to do this. Have a look at this project.

Follow the below steps :

  1. Write a script in python (scapy) to sniff your desired traffic.

  2. Write a script in bash with iwconfig (as mentioned above) with following syntax:

    for i in {1..13}
do
    iwconfig $1 channel $i
    sleep 5s
done

    Or use while if you want.

  3. Finally use the & operator to run both of them.

NOTE: keep both scripts in same directory or you have to use environment variables.

finally for your answer both scripts running:
