Live Packet

[Protocol Analyzer]

A Python-based network protocol analyzer built using the scapy library. This tool captures and analyzes network traffic for protocols like TCP, UDP, and HTTP. It provides an interactive command-line interface (CLI) for users to select protocols and analyze packets in real-time.

Features

1: Protocol Analysis: Supports TCP, UDP, and HTTP traffic analysis.

Interactive CLI: User-friendly menu for selecting protocols and specifying the number of packets to capture.

Payload Decoding: Decodes and displays HTTP payloads for easier analysis.

Cross-Platform: Works on Linux, macOS, and Windows (with appropriate permissions).

Installation

Prerequisites

• Python 3.x

• scapy library

Steps

• Clone the repository:

git clone https://github.com/livepwn/livepacket.git

cd livepacket

• Install the required dependencies:

pip install scapy

• Run the script:

chmod +x livepacket.py
or
sudo python livepacket.py

Note: sudo is required for packet capture on most systems.

Usage

Running the Analyzer Start the script:

sudo python liveport.py
Follow the on-screen prompts:

Select a protocol to analyze (TCP, UDP, or HTTP).

Specify the number of packets to capture.

View the captured packets and analysis in real-time.

Advantages

Ease of Use:

• The interactive CLI makes it easy for users to select protocols and analyze traffic without needing to write custom scripts.

Real-Time Analysis:

• Captures and analyzes packets in real-time, providing immediate insights into network traffic.

Extensible:

• The modular design allows for easy addition of new protocols and features.

Lightweight:

• Built with Python and scapy, the tool is lightweight and does not require heavy dependencies.

Supported Protocols

Protocol	Description
TCP	Analyzes TCP packets and payloads.
UDP	Analyzes UDP packets and payloads.
HTTP	Analyzes HTTP traffic on port 80.

Future Enhancements

• HTTPS Support: Add support for analyzing HTTPS traffic (port 443).

• Packet Saving: Save captured packets to a .pcap file for offline analysis.

• Advanced Filtering: Add filters for IP addresses, port ranges, and specific protocols.

• GUI: Develop a graphical user interface (GUI) for easier interaction.

Acknowledgments

• Scapy: The powerful Python library used for packet manipulation and analysis.

• Python Community: For providing excellent resources and support.
