by running this program, it shows some information about the packet. The information contains the destination and source MAC address for the packet, the ethernet frame and the protocol name. (Till now It just understands 4 protocols, I'll add the rest later.) For TCP protocol, it provides source port and destination port.
The program requires linux OS (I know it's crazy but whatever). For running the program make sure you have root access. You can use the following command :
sudo python3 main.py
