Build a Self-Hosted SSH Tunneling Server with Per-User Accounting (Abdal 4iProto)

Build a Self-Hosted SSH Tunneling Server with Per-User Accounting

If you want a self-hosted SSH tunneling server that handles bandwidth limits, session control, and brute-force protection without you scripting any of it, this walkthrough is for you. We'll set up Abdal 4iProto Server — a Go-based tunnel by Ebrahim Shafiei (EbraSha) — from build to first connection, and I'll explain the config decisions along the way so you're not just copy-pasting blindly.

Heads up: this server is part of the broader Abdal 4iProto ecosystem (https://github.com/4iProto), so there are matching clients and tools once your server is up.

What you'll have at the end

A running tunnel server with per-user speed caps, total-traffic quotas, concurrent-session limits, automatic IP blocking on failed logins, and a SOCKS5 endpoint your apps can use. Let's go.
