Set up a "relay" service

  • 772

I'm trying to create a 'left client' > server < 'right client' setup but need some advice and tips.

Let's say that I have a server-daemon on the left side, like a vnc-server that connects to the middle server.

On the right side I've got a client that want to connect to the left server-daemon, but it has to be done through the middle server. I assume this should be done with some tunneling service.

The server environment is a fully featured Debian Linux or Mac OS X Server host.

Any idéas?

Thanks / Trikks

  1. SSH port forwarding? If you have to requests from right to the server on left you could do something like:

    From right

    ssh -L 5900:localhost:5900 middle

    From left

    ssh -R 5900:localhost:5900 middle

    The first command sets up a tunnel, and will forward port 5900 from right to middle, and the second is a reverse tunnel, and will forward port 5900 from middle to left. These two commands should effectively provide a tunnel from right to left (I have not tested it, though)

    Tried rinetd?

    For arbitrary forwarding it's probably the easiest.
