I have created a wireless access point on ubuntu and I have written a program that parses network traffic obtained via tshark and condenses it into a readable form. I am able to capture traffic going to and from the internet. Now i have three nodes on my network:
Node A: The wireless access point running tshark
Node B: Computer 1
Node C: Computer 2
To create TCP traffic in my network, i used nmap on Node A to scan Node B but i am unable to capture that traffic. Any clue how to do that?
I tried putting my network interface card in promiscuous mode but that didn't help.
