A simple Wi-Fi packet sniffer and monitor built in Java using JNetPcap 1.3.
This project captures wireless packets in monitor mode and prints information to the console. It’s a learning project built while exploring packet capture and the JNetPcap library.
- 📡 Monitor mode Wi-Fi packet sniffing
- 🧠 Built with Java + JNetPcap 1.3
- 🐞 Simple learning / exploratory tool for network capture
- 📜 Code comments reference JNetPcap guide sections
This tool uses JNetPcap (an older Java wrapper for libpcap) to:
- Open a network interface in monitor mode
- Capture live packets
- Print packet summaries and details to console
- (Future) Dump packets to file
The code is intended for learning and experimentation — not production–ready.
- Java (JDK 8+)
- JNetPcap 1.3 library installed and on your classpath
(native libraries must be available for your OS) - A wireless interface capable of monitor mode
- Required OS privileges (root / administrator)
