A terminal network monitor for Linux. Shows real-time interface throughput, open listeners, and active TCP connections split by direction (outgoing / incoming). Built with ratatui.

• Per-interface RX/TX rate with sparkline history
• Listener table: port, protocol, process, user
• Outgoing connections: remote address, traffic rate, process
• Incoming connections: same columns, filtered by direction
• Interface selector with tab navigation
• Kill a process from the listener or connection view (SIGTERM)

• Linux (reads /proc/net, /proc/<pid>/fd, /proc/net/fib_trie, etc.)
• Rust toolchain (stable)

Download and install the latest release with a single command:

Clone the repository and build the project using the provided scripts (requires Rust and UPX):

git clone https://github.com/sammwyy/ns.git
cd ns
./scripts/build.sh
sudo ./scripts/install.sh

Running as a regular user is enough for most data. Process names and PIDs for sockets owned by other users require root.

ns

• Load — RX and TX sparklines for the selected interface
• Listeners — open TCP/UDP ports
• Outgoing — established TCP connections initiated by this host
• Incoming — established TCP connections accepted by this host
