Forward from local port 9000 to remote port 9999įunc forward(localConn net.Conn, config *ssh. It doesnt work with dropbear ssh client or the golang standard ssh library. where we can configure all the relevant ports in one go. I switched to cloudflare tunnels from ngrok a while back after having some. Basically my solution establishes an ssh tunnel to the remote server and queries the remote database through this tunnel. Create ClientConfig ssh.Dial to remote SSH server with the config and return Client Now you can use Client.Dial to forward anything you like.

The core code is similar to damicks answer. It provides HTTP proxy instead of SOCKS proxy, which is really similar to ssh -D. However, the multiplexed nature of SSH is exposed to users that wish to support others. Iv finished a simple SSH port forward tool called mallory. The most typical application level protocol is a remote shell and this is specifically implemented. SSH is a transport security protocol, an authentication protocol and a family of application protocols.

Continually copy remote io.Reader bytes to local io.Writer. Im able to setup the RDP connection with a SSH Tunnel (with Use over secure gateway ticked). Package ssh implements an SSH client and server.

Upon attempted read from local port 9000: ( listener.Accept()), For example, one could connect to a remote server via SSH on the remote service and provide this service to the local service on some given TCP port.

Here is an attempt to relate the essence of what this code does: Mole is a cli application to create ssh tunnels focused on resiliency and user experience. Thanks to all!Ī big part of the problem I was having was that I did not realize a local net.Listener (not just a local net.Conn) needed setup to receive a local request and create the net.Conn before forwarding the bytes.Īlso, there exist both port forwards and reverse port forwards and I hadn't previously thought in detail about the fact that a regular port forward also sends bytes back, so copying the remote reader to local writer was not something I had implemented, yet it's very much needed.
