Managing multiple Sunshine backend on a single host

[ABeltramo]

This is something that has been requested over and over again:

Can I let different users share a single machine for multiple gaming sessions at the same time?

Bare in mind that Moonlight does support already multiple players sharing one gaming backend (Sunshine) for Co-Op or similar games. In order to use that change the channels param in the Sunshine conf file.

There are multiple issues that needs to be solved in order to achieve this:

• Right now Moonlight doesn't support connecting to different ports. I tried using nginx for this so that we can reverse proxy in front but since it's not HTTP but on a lower stack: TCP/UDP there's no easy way to dispatch based on the domain name (see the section below)
  • One way around it for now is to manually re-compile the client with a different set of hardcoded ports.
• Having separate X11 display per remote player, this probably can be achieved using Xorg multiseat but needs testing (Thanks to @diadatp for pointing it out!)
• Separate uinput devices so that keyboard/mouse/controller don't clash with each other.

Nginx reverse proxy Sunshine

I was able to passthru from one host to one other host so that Moonlight was pointing to x.x.x.x and Nginx was redirecting the connection to y.y.y.y
This works fine, but I wasn't able to dispatch based on the domain name or even just to load balance between 2 or more backends).

[1] Here's my nginx.conf file

events {}

stream {

   server {
        listen 47998 udp;
        listen 47999 udp;
        listen 48000 udp;
        listen 48002 udp;
        listen 48010 udp;

        listen 47984;
        listen 47989;
        listen 48010;

        # This can possibly be bound to an upstream so that you can load balance between backends
        # I couldn't make it work with the $server_port variable
        # But probably some wizard can
        proxy_pass y.y.y.y:$server_port;
    }

And I started it using

sudo docker run --name nginx --rm -v ~/nginx-gow.conf:/etc/nginx/nginx.conf:ro -p 47998-48010:47998-48010/udp -p 47984-48010:47984-48010/tcp nginx:1.21-alpine
