Computer WebSocket over SSH tunnel - is it possible?
Hello,

I have a video streaming application that utilizes a WebSocket for the server <-> client communication. My goal is to make the video streaming service available over the internet in the cases where neither the server nor client have public IPs.

One way to do this is over a VPN connection, but I prefer not to use a VPN at all. That's why I decided to try and forward the communication over an SSH server via remote port forwarding.

However I am facing an issue - forwarding the server socket is pretty straight-forward, but I have no way to know in advance what the randomly allocated client port will be, so the traffic will flow only in the direction client -> SSH server -> streaming server.

When the SSH relay point receives the responses from the streaming server it does not automatically route them back to the client and the WebSocket handshake cannot be completed.

Do you think it is possible to overcome this issue or should I drop the WebSocket altogether and revert to a normal HTTP / TCP connection?

Thanks!

mosh-client

MOSH(1) 						      General Commands Manual							   MOSH(1)

NAME

       mosh-client - client-side helper for mosh

SYNOPSIS

       MOSH_KEY=KEY mosh-client IP PORT
       mosh-client -c

DESCRIPTION

       mosh-client is a helper program for the mosh(1) remote terminal application.

       mosh  itself  is a setup script that establishes an SSH connection, runs the server-side helper mosh-server, and collects the server's port
       number and session key.

       mosh then executes mosh-client with the server's IP address, port, and session key. mosh-client runs for the lifetime of the connection.

       The 22-byte base64 session key given by mosh-server is supplied in the MOSH_KEY environment variable. This represents  a  128-bit  AES  key
       that protects the integrity and confidentiality of the session.

       For constructing new setup wrappers for remote execution facilities other than SSH, it may be necessary to invoke mosh-client directly.

       With the -c option, mosh-client instead prints the number of colors of the terminal given by the TERM environment variable.

SEE ALSO

       mosh(1), mosh-server(1).
