A real-time network packet capture and analysis tool built in Python using Scapy. This project tracks every packet source to destination ,protocol analysis and cybersecurity fundamentals.
- Captures live network packets from your machine
- Identifies common protocols such as — TCP, UDP, ICMP
- Detects frequently used services including — HTTPS, DNS, SSH, HTTP
- Counts packets per IP address
- Track packet activity by IP address
- Flags suspicious IPs exceeding packet threshold
- Shows "top talkers" with visual bar chart
- Generates detailed timestamped reports saved to file
- Clone the repository
git clone https://github.com/amlan-sinha07/packet_analyzer.git
cd packet_analyzer- Install dependencies
pip install scapy- Install Npcap (Windows only)
- Download it from https://npcap.com
- During installation, make sure to check the box that says "WinPcap API-compatible mode".
Run as Administrator (required for packet capture):
python main.pyThis application will ask for:
Enter number of packets to capture and suspicious IP threshold when prompted.
After capture, the analyzer will display statistics and generate a report that can be saved for future reference.
- Python 3.11
- Scapy — packet capture and analysis
- datetime — timestamping
- os — file and folder management
