Packet Sniffer

Description

The Network Sniffer, a Python-based tool, offers real-time packet capture and analysis, providing insights into various network protocols.

Features

• Captures and analyzes Ethernet frames to extract MAC addresses and protocol information.
• Parses IP packets to determine source and destination IP addresses, TTL (Time-To-Live), and transport layer protocol.
• Supports parsing of ICMP, TCP, and UDP packets to extract specific protocol details.
• Provides real-time updates on captured packets, displaying packet details and protocol information as they are intercepted.
• Includes packet statistics functionality to track the count of packets per protocol and display statistics every 10 seconds.

Requirements

• Python 3.11
• Terminal or Command Prompt

Steps to Run

1. Clone the repository

   git clone https://github.com/Melvin-Shalom/Packet_Sniffer.git

2. Navigate to the project directory

   cd Packet_Sniffer/

3. Create & activate the virtual environment

   python -m venv venv
   source venv/bin/activate    # For Linux/macOS
   .\venv\Scripts\activate     # For Windows

4. Install dependencies

   pip install -r requirements.txt

5. Run the packet sniffer script

   sudo venv/bin/python3 main.py   # For Linux/macOS
   python main.py                  # For Windows

Usage

Run the script to capture and analyze packets. Stats are printed every 10 seconds, providing protocol-wise packet distribution.

Future Scope

• Add GUI for live traffic visualization
• Export packet logs in .pcap format
• Filter packets by IP, port, or protocol
• Integrate with threat intelligence APIs
