SSH3 on a Mac
SSH over QUIC/HTTP3 — faster handshakes, hidden behind a secret URL · Networking
SSH3 reimplements the SSH experience on HTTP/3 + QUIC + TLS 1.3: quicker session setup, UDP port hopping, certificate-based server identity, and a server that can hide behind a secret URL path on UDP 443 — to a scanner it looks like any HTTPS/3 endpoint. It's a separate young project (github.com/francoismichel/ssh3), not OpenSSH: run ssh3-server on the server with a hidden path, install the ssh3 client here (Go: go install), then pick SSH3 (QUIC) as *Connect via* in the fleet server's settings and enter the port + secret path. Treat it as experimental — keep plain SSH available as a fallback; FrontierStack's probes and file transfers always use it regardless.
Run SSH3 with FrontierStack
FrontierStack lists SSH3 in its Networking catalog. Install or connect it from one place, then monitor its status, ports and certificate, secure it with the firewall and Malware Audit, and back it up.
Run it all from one Mac app.
FrontierStack installs, monitors and secures the whole stack — locally and across your fleet — from a single native macOS app.
