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

Install or connect SSH3; then check its status, ports and certificate from FrontierStack. The same screen links to firewall checks, Malware Audit and backups where they apply.
