Greet is a lightweight Go library to test greet / ping / handshake process in TCP, UDP and other popular protocols based on them.

Goals

• Fast: The library only performs handshake without entering full session
• Secure: The process ends before authentication / authorization step
• Lightweight: The library constructs raw command from scratch and does not depend on third-party service clients
• Tracing: The library outputs helpful errors from connection init to handshake
