A simple network packet analyzer written in Rust for learning purposes. This project demonstrates Rust programming concepts and networking fundamentals by implementing basic packet capture and filtering functionality similar to tcpdump. Features include protocol filtering (TCP/UDP), port-based filtering, host filtering, and multiple output formats.
- Rust (latest stable version)
- Root/administrator privileges (required for packet capture)
