Open Ports

See what is listening and what changed.

Inventories local TCP and UDP listeners, records a baseline, and compares later scans. It does not probe remote systems.

Start

cargo run -- scan --format table

Run the command with --help for every option. The tool works locally, collects no telemetry, and supports machine-readable output where applicable.

Principles

• Local first. Host data stays on the host unless you explicitly configure a webhook.
• Safe by default. Inspection is read-only and mutation requires a deliberate command.
• Small contract. The tool solves one defensive job and reports its limits plainly.
• Scriptable. Stable exit codes and structured output make automation practical.

Platform

The initial release targets Linux. Portable behavior is also tested on Windows where the underlying operating-system facilities allow it. See the threat model for trust boundaries and non-goals.

Development

This repository uses Rust without third-party crates.
