Bukkit

There are several different rcon commands that you can use with Bukquery. Note that these commands can only be used from a rcon connection - you will receive an "unknown command" message if you try to execute these ingame or via the console.

• rcon bye - the most basic of rcon commands. This disconnects you safely from the rcon server. In response, you will receive "rcon kick disconnect.connectionClosed".
• rcon auth - allows you to authenticate the rcon connection. This must be executed before any other rcon command, otherwise the server will send "rcon authRequest" to you. It accepts the authentication key as a parameter. If authentication succeeded, you will receive "rcon authResponse ok" - otherwise, you will receive something similar to "rcon authResponse fail 1 3" (1 being the amount of attempts out of 3 maximum).
  Example:
  rcon auth asdfqwererurueureudru333234434
• rcon who - allows you to see who is online. Player names are seperated by a space.
  Example response:
  rcon who Notch jeb_ griefer1234
• rcon countPlayers - allows you to see how many players are online out of how many players maximum. Assuming 37 players are online out of 120 maximum, this will be the response:
  rcon countPlayers 37 120
• rcon name - changes the name by which the rcon command sender is identified as. This appears in front of Minecraft "op commands". Accepts the new name as a parameter. By default, the name is [rcon].
  Example:
  rcon name AlertSystem
