I have two Ubuntu boxes set up: one running 12.04 Server and one running the standard desktop version of 12.04.
I can ssh into my server computer from my desktop using terminal (using ssh spin@192.168.0.xxx -p 22), but when I try to do the same thing from my GNOME desktop (using 'File > Connect to Server') I immediately get "connection refused by server".
In the dialog box I use the same port number (22), the same user (spin), the same IP address and select 'SSH'. I leave the 'folder' option as '/'.
What am I missing?
