Show HN: Rapid SSH Proxy

Rapid SSH Proxy. Like ssh -ND, but much faster.

rsp is a SSH client which implements SOCKS5 proxy feature of SSH protocol. Key feature of this implementation is use of multiple connections to overcome downsides of multiplexing many tunneled TCP connections in single SSH session. Multiple sessions are not limited with TCP window size of single connection and packet loss does not affect all tunneled connections at once. In order to cut latency of connection establishment rsp maintains pool of steady connections, which replenished with configurable rate.

Features:

- High speed as compared to conventional OpenSSH client.

- Cross-platrorm (Windows, Linux, macOS and other Unix-like systems).

- Zero-setup required for server. rsp can be used right away with any SSH server.

- Self-sufficient: doesn't require OpenSSH on client side to operate.

- SOCKS5 remote DNS support.

- Connection establishment latency hidden from user with asynchronous connection pool.

- Connection establishment rate limit guards user from being threated as SSH flood.
