Streaming Network Overlay Connection Arbitration Tunnel

snocat is a framework for forwarding streams across authenticated, encrypted QUIC tunnels, from a tunnel aggregator to a dynamic set of clients.

When used as a library, libsnocat allows a dynamic set of clients to connect over UDP to a server, and forwards TCP streams from the server to the clients.

snocat-cli is a command-line tool for TCP reverse tunnelling over the QUIC protocol. It allows small-scale port redirection akin to SSH Remote Forwarding.

Primary crates used include the Tokio stack and futures-rs for async-await capabilities, Quinn for its QUIC implementation.
