The Remote Console (RCON) tools exist to help you administer your server without connecting as a player.

There are two ways to invoke RCON: HTTP Requests, and the RCON Protocol.

Setup[edit]

to-doc The setup process is not finalized yet, as I want you to be able to assign RCON keys permissions and configure the port in the server config.

HTTP Requests[edit]

Intended for web-based control panels to run commands on the server.

Requests can be sent to {Server}/rcon/{Command}?key={Key}&arg1=value1&arg2=value2.

Key Value
Command ID of a command as it would be used in chat, such as teleport or tp
Key An authorized RCON key you have assigned permissions to run this command.
Arg Key = Value pairs of arguments to the command.

Responses are returned in JSON. If a command was found and executed the response looks like:

{
    "Success": true,
    "Output": "{Logs}"
}

Whereas a failed response which did not execute a command will contain an error explanation:

{
    "Success": false,
    "Error": "{Explanation}"
}

RCON Protocol[edit]

Using the protocol is more complex than the HTTP requests, but has the advantage of streaming log data from the server.

To keep things simple it is implemented as null-terminated UTF8 messages over a TCP socket connection.

All RCON messages start with "RCON" followed by the version number, the type of message and then any parameters.
