Authentication can use normal UNIX password, but across encrypted channel. After authentication, SSH Secure Shell functions like other terminal clients. Starting a process that spawns an X display will automatically forward the X display to the local X server. The X display will open on the local X server. Both incoming and outgoing tunnels can be created.
Setup is straightforward, but requires knowledge of port numbers for services on server and client.
Once set, port forwarding can be altered or deleted. Settings are saved from session to session, so it is necessary to set port forwarding only once, unless a change is needed. The GUI looks similar to a typical file manager, in which the file system is shown hierarchically. The interface shows the file system for the server. Files can be dragged from the client's Windows Explorer.
