C Shell scripts for Minecraft dedicated servers, based on a RCON reimplementation.
rcon_announce: Periodically display a set of three messages after five minutes + two other messages, after 30 seconds, counted from the five minutes.
rcon_commands: Execute commands requested by a player; currently, the commands are: !date (date Unix command), !info (uname -a Unix command), !script (script information; credits), !warp (manage warps), !guild (manage guilds) and !roll (roll a dice).
rcon_auth: Authenticate players, basing on usernames and IP addresses.
rcon_interactive: Interactive remote connection.
Do not have the server running, change the scripts' execution permissions and run the following:
mkfifo /tmp/rcon_in ; tail -f /tmp/rcon_in | java -jar <path/to/server.jar> server nogui &
tail -f <path/to/server.jar/logs/latest.log> | ./rcon_auth &
tail -f <path/to/server.jar/logs/latest.log> | ./rcon_commands &
./rcon_announce &
To enable external RCON connections, install socat and do the following:
(For logs.) socat -U tcp-l:<port>,fork,reuseaddr exec:"tail -f <path/to/server.jar/logs/latest.log>" &
(For commands.) ( nc -p<port> -kl > /tmp/rcon_in & )
To have RCON access, do the following:
(For logs.) nc <server ip> <port> &
(For commands.) echo <command> | nc <server ip> <port>
Windows users may use Cygwin to run the scripts.
Because Minecraft's RCON is terrible, I had to implement one, with a FIFO (first in, first out).
The scripts should work on both original and CraftBukkit/Spigot servers.
On Unix and Unix-like operating systems, it is recommended to have a tmpfs mount on /tmp.
