Network Packet Sniffer is a simple and interactive tool written in Python, inspired by real-world network monitoring tools. You can capture live network packets and analyze them in real time. The tool features a Tkinter-based GUI, protocol-wise traffic summary, and detailed packet inspection.
This project is developed using Python with Scapy and Tkinter. It provides a visual interface to capture and analyze network packets, allowing users to see TCP, UDP, and ICMP traffic in real time. Key functionalities include:
- Live packet capture
- Protocol-wise summary (TCP, UDP, ICMP)
- Color-coded packet rows
- Detailed packet analysis in a popup window
- Start/Stop capture buttons
- Protocol filtering options
This project is ideal for beginners learning about:
- Network traffic monitoring and analysis
- Packet sniffing with Scapy
- Building GUI applications with Tkinter
It also demonstrates how Python can be used to create practical cybersecurity tools with interactive interfaces.
- Run the script using Python:
python packet_sniffer.py
Click ▶ Start Capture to begin sniffing packets.
-
Packets will appear in the Packet Details table in real time.
-
Click on any packet to view full details in a popup window.
-
Use ⏹ Stop Capture to stop sniffing.
-
Filter packets by protocol (All, TCP, UDP, ICMP) using the dropdown menu.
- Live capture of network packets
- Protocol filtering (TCP, UDP, ICMP)
- Color-coded rows based on packet type
- Timestamped packet details
- Popup window for full packet inspection
- User-friendly GUI with Tkinter
- Python 3.8+
- Scapy (for packet sniffing and analysis)
- Tkinter (for GUI interface, usually pre-installed with Python)
- Threading & Collections (standard Python libraries)
- Works on Windows, Linux, or macOS (requires network access permissions)
