Use minecraft's new-fangled Rcon
License: Other
Straightforward implementation of Minecraft's Rcon protocol in Python.
mcrcon.py is a module you can import from your own python code to send
commands to a minecraft server and read responses.demo.py is a simple command-line client that lets you do the above without
writing any code.
Is there a way to output all of the server messages without having to send a command?
Traceback (most recent call last):

return getattr(self._sock,name)(*args)
socket.error: [Errno 111] Connection refused
I always get this error, password length is 20:
Traceback (most recent call last):

in_length, = struct.unpack('<i', self.socket.recv(4))
struct.error: unpack requires a bytes object of length 4
It occurs for python2 and for python3. Do you experience the same?
Hi, I installed mcrcon and it connects just fine, but in the terminal I have some sort of encoding problem. My terminal is set to use UTF-8 (gnome 3/arch linux), but up-arrow gives instead of command history output you can see on the bottom line and ? gives this output with strange characters. Could you help with this please?

That is when I set encoding to Western ISO-8895-1
Running the following code will crash the Minecraft server. My guess is that the Minecraft server is still parsing the result of the executed command and the "connect()" function quits too soon.
import mcrcon
server = mcrcon.MCRcon(host='x.x.x.x', port=25575, password='asdf')
server.connect()
server.command('/fill 639995 11 639995 640069 15 640069 water replace')
Possibly adding a "waittime" variable to pass with the connect() function could solve this?
There's no license here. I'd like to use this for a tool I'm building. Any chance you could add an MIT license or other?
I can use other RCON tools to run commands/query my server, but with your demo.py, I get the following. Please let me know if there is any other information I can provide to aide in solving this issue.

How would you make it so it sends in a print of what the output of the command was?
Some commands have a long output (e.g. "pex" from PermissionsEx) which cause MCRcon to not fully return the command output in the command() or send() methods.
Once a command with a long output is sent, the next command sent to the server returns the remaining part of the previous command and all following commands return the response of the previous one.
Example using demo.py (executing the commands "pex", "dynmap", "essentials", "", ""):

To work around MC-72390, I think it would make sense to introduce a 0.003 second delay between commands.
I’m making a discord bot that, when given a command, will execute the command in the console, everything connects, but the error comes up: unpack requires a buffer of 8 bytes.
