Mock MUD Server

This is a mock MUD server implementation that demonstrates GMCP Authentication support.

Overview

• The actual implementation relevant to the spec is in a few lines of Python: https://github.com/vadi2/gmcp-auth-mock/blob/main/mock.py#L53-L77

Usage

To start the server:

python mock.py

By default it will listen on localhost:2003.

To connect:

• Use a MUD client that supports GMCP Auth
• Connect to the server on port 2003
• The server will initiate GMCP negotiation
• Send credentials in the GMCP authentication flow:
  • Account: admin
  • Password: hunter2

The server will also accept a plain text password of hunter2.

Implementation Details

• start_server() contains the main server loop
• send_gmcp() helper to send GMCP messages
• send_text() helper to send plain text
• process_data() parses incoming data and handles GMCP

The server listens for connections in a loop. When data is received:

• GMCP messages are parsed from the telnet data
• On Char.Login messages, the credentials are checked
• Responses are sent over GMCP and plain text

This shows a basic GMCP implementation and authentication flow.
