Packet Sniffer in Python

Overview

This is a Python-based packet sniffer that captures and analyzes network packets. It provides functionalities such as real-time packet capturing, protocol decoding, and output logging.

Features

• Captures packets in real time
• Supports multiple network protocols (requires netprotocols module)
• Outputs packet details to the console
• Provides filtering options (future enhancement)
• Saves captured packets to a file (planned feature)

Requirements

• Python 3.x
• socket module (built-in)
• struct module (built-in)
• netprotocols module (currently missing, needs implementation)

Installation

1. Clone this repository:

   git clone https://github.com/paurush4/CodeAlpha_PacketSniffer.git
   cd packet-sniffer

2. Ensure you have Python installed:

   python3 --version

3. Install dependencies (if required in the future):

   pip install -r requirements.txt

Usage

Run the packet sniffer with:

python3 sniffer.py

Project Structure

Future Improvements

• Implement the netprotocols module for enhanced packet decoding.
• Add filtering options to capture specific protocols.
• Optimize performance for high-speed network traffic.
• Save packet logs to a file for later analysis.
