Answer 1

I'v finished a simple SSH port forward tool called mallory. It provides HTTP proxy instead of SOCKS proxy, which is really similar to ssh -D.

The core code is similar to damick's answer.

1. Create ClientConfig
2. ssh.Dial to remote SSH server with the config and return Client
3. Now you can use Client.Dial to forward anything you like.

   Dial initiates a connection to the addr from the remote host. The resulting connection has a zero LocalAddr() and RemoteAddr().

4. If you want to serve a SOCKS proxy server, use Client.Dial to connect to the remote server.
