This Network Protocol Analyzer captures and logs network traffic in real-time using Python and the Scapy library. It provides detailed information about network packets, including timestamps, source/destination IP addresses, protocol details (TCP/UDP), and port numbers. The analyzer automatically selects the best available network interface and logs a configurable number of packets to prevent excessive log file sizes. This tool is invaluable for network monitoring, analysis, and troubleshooting.

• Real-time Packet Sniffing: Captures network traffic in real-time using Scapy. 📡

• Automatic Interface Selection: Automatically selects the optimal network interface for capturing packets. 💻

• Detailed Logging: Logs essential packet details (timestamp, summary, source/destination IPs, protocol, ports) to network_traffic.log. 📝

• Packet Type Identification: Identifies IP, TCP, and UDP packets and extracts relevant information. 🔎

• Configurable Logging Limit: Limits the number of logged packets (default 20) to manage log file size. 🔢

• Informative Packet Summaries: Provides brief summaries of each captured packet. ℹ️

• Python: The core programming language for the analyzer. 🐍

• Scapy: A powerful Python library for network packet manipulation and analysis. 📡

• Network Administrators: Monitoring and analyzing network traffic for troubleshooting and security. 🧑‍💻

• Security Researchers: Investigating network communications and potential threats. 🕵️‍♀️

• Network Engineers: Analyzing network protocols and performance. 👨‍💼

• Python Developers: Learning about network programming and packet analysis with Scapy. 🧑‍🎓

1. Clone the repository: git clone <repo url>

2. Install Scapy: pip install scapy

3. Run the program (with appropriate permissions): python network_analyzer.py (or python3 network_analyzer.py) You may need administrator or root privileges to capture network traffic.
