v0.1.0 — Early Release

Last updated August 2026

The first public release of Portis, an adaptive TCP port scanner designed for high-latency and unstable networks.

Portis measures the network before scanning, then automatically configures concurrency, timeouts, and retry behavior.

Portis calibrating a target network, scanning TCP ports, retrying uncertain responses, and generating an nmap handoff — Portis adaptive scan workflow

Features#

Adaptive network calibration
Concurrent TCP connect scanning
Automatic retries for uncertain responses
Port ranges, lists, top ports, and full-range scanning
Machine-readable JSON output
Suggested nmap handoff command for service enumeration

Installation#

Download portis-linux-amd64 and checksums.txt from the latest GitHub release.

Terminal

$ sha256sum -c checksums.txt
$ chmod +x portis-linux-amd64
$ sudo mv portis-linux-amd64 /usr/local/bin/portis
$ portis -h

Quick start#

Run Portis against a host you own or are explicitly authorized to test.

Terminal

$ portis -ip 10.0.0.5 -port 1-1000

Platform#

Linux AMD64
No root privileges required
IPv4 TCP connect scanning

How it works#

Portis calibrates against the target network, scans ports concurrently using the observed conditions, rechecks uncertain responses, and prints an nmap command containing only confirmed open ports.

Early-release note
Full-range scanning remains experimental. Further accuracy, performance tuning, broader testing, and feature upgrades are planned.
