Network Packet Analyzer

Overview

The Network Packet Analyzer is a Python-based tool designed to capture and analyze network packets. Built using the Scapy library, this tool provides an easy-to-use interface for monitoring network traffic and examining key details such as IP addresses, protocols, and payload data. It is intended for educational purposes and must be used ethically with explicit permission on the networks being monitored.

Features

• Packet Capture: Captures network packets in real-time.
• Detailed Analysis: Displays source and destination IP addresses, as well as packet protocols (TCP, UDP).
• Payload Inspection: Shows payload data for TCP and UDP packets.
• Logging: Saves captured packet details to a text file for later review.
• Ethical Use: Includes a disclaimer and consent mechanism to ensure responsible use of the tool.
