I am learning about network packets and I was wondering how I could intercept and modify and/or create a packet and send it?
- I have Windows OS.
- I would prefer an easy to use and easy to understand program.
- If possible, a program that can create and modify packets would be nice. But if there is no program that can do both please point me to two programs that can do each.
- If there is one out there with a GUI, that would be very helpful to me.
- A program that intercepts packets and allows for modifying, not just HTTP.
I have tried TcpCatcher, but for some reason it does not seem to capture any packets.
