(https://github.com/skeeto/endlessh) Endlessh is an SSH tarpit that very slowly sends an endless, random SSH banner. It keeps SSH clients locked up for hours or even days at a time. The purpose is to put your real SSH server on another port and then let the script kiddies get stuck in this tarpit instead of bothering a real server. endlessh-go (https://github.com/shizunge/endlessh-go) is a golang implementation of endlessh with additional features including exporting Prometheus metrics.

Health score?A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). When the source code has been checked, a fifth factor, security check (20%: automated scan for committed secrets, unsafe desktop-app settings, known-vulnerable dependencies and project hygiene; any serious finding caps it at 20), is added. Factors without data are left out and the rest are rescaled.

Common questions

How should I place endlessh-go if I also run a normal SSH server?

Put the real SSH server on another port and let the tarpit answer on the port that scanners normally hit.

Does endlessh-go support dashboards or metrics?

It exports Prometheus metrics and can be visualized by a Grafana dashboard.

Do recent scanners still stay connected for long periods?

One self-hosted user reports scanners now stop after 20-30 seconds, after 2-3 responses, instead of staying connected for days.
