Features

• Capture and analyze network packets.
• Display source and destination IP addresses.
• Identify the protocol used (TCP, UDP, ICMP).
• Show source and destination ports.
• View the payload data of packets.

Prerequisites

• Python 3.x: This program requires Python version 3.x. You can check your Python version by running python --version or python3 --version in your terminal. If you do not have Python 3.x installed, you can download it from the official Python website.

Installation

1. Clone the repository:

   git clone https://github.com/PhantomMenace404/PRODIGY_CS_05.git
   cd PRODIGY_CS_05

2. Install dependencies:

   pip install scapy rich

Usage

1. Run the script:

   sudo python3 packet_probe.py -i <network_interface>

   Replace <network_interface> with the appropriate network interface (e.g., eth0, wlan0). Note that sudo privileges are required to capture packets.

2. Interact with the program:

   • The tool will start capturing packets on the specified network interface.
   • Information about each captured packet will be displayed in a table format.
   • To stop capturing packets, press Ctrl + C.
