Original GitHub issue: https://github.com/GameServerManagers/LinuxGSM/issues/4720

User story

As a rust server owner, I need LGSM to stop the server via a quit RCON command to trigger a clean save on exit

Game

Rust

Linux distro

Ubuntu 24.04

Command

command: stop

Further information

LGSM's default stopmode for Rust is CTRL+C, which causes a hard shutdown that tends to have nasty side effects like forgetting teams, because the server doesn't get a chance to generate a full save.

Changing stopmode to quit results in failure, apparently because LGSM tries to send it to the server console instead of via RCON.

Relevant log output

rustserver@ubuntultsvm:~$ ./rustserver stop
[ ERROR ] Stopping rustserver: Graceful: sending "quit": FAIL
[  OK  ] Stopping rustserver: LinuxGSM



### Steps to reproduce

1. Configure server for `stopmode=3`
2. `./rustserver start` and wait for server startup to complete
3. `./rustserver stop`

Glad someone submitted this. Kept getting told I was doing it wrong even though I had tried every stop mode I thought made sense.

I am unsure on how to resolve this as LinuxGSM does not have RCON access to servers and Rust does not have an interactive console which we somtimes use. Different game servers have very different RCON protocols or none at all which adds a lot of complexity as I would need to add bespoke support for different game servers. Most game servers typically can handle graceful shutdown when CTRL+c or equivalent is triggered.

I only found 1 previous issue highlighting a similar issue but was closed due to inactivity. It would be great to get some input from other Rust admins to see if they also experience a similar issue and how they resolve it. If there are any suggestions I am happy to look at implementing if practical to do so.

May need to use an RCON client like this that can run from command line. I haven’t tried it yet. fieu/phust: Send RCON commands to your Rust server via the command-line ⛏github.comIf LGSM has an option to supply a custom stop command, that could help, maybe?

Rust's RCON protocol is pretty simple. I've been able to write C++ apps that talk with it just by using a websocket library combined with a JSON library.

I have a bash script using https://github.com/fieu/phust for rcon commands, it requires PHP though.
https://gist.github.com/atomy/9460458a319d32958f59736585b3ccd5

I am wondering how I can use it for graceful shutdown, any place where I can hook that in? Maybe create my own stopmode or something?

So I added another stopmode and used my script, I tested it, it works quite well.

https://github.com/atomy/LinuxGSM/pull/1/files

However, the rcon tool I am using is not that great, it should probably be changed to https://github.com/gorcon/rcon-cli
Also this issue is relevant here if not even a dupe: https://github.com/GameServerManagers/LinuxGSM/issues/4419

Having a quick look it appears that this tool might be a good option to solve this issue. However a mechanism to pull in this dependency would need to be created https://github.com/gorcon/rcon-cli
