How it works

Listens on 2 ports:

• UDP 27900: on which dedicated servers register and send keepalive packets containing a lead byte (unknown) and the game port in ASCII. gckmsd checks the game server before adding it to its list of servers.
• TCP 28900: on which clients send queries. Replies must follow this format:
  {server index on 2 digits}0xac{server ip in ASCII}0xac{server port in ASCII}0x00[next server]
