One thing to check is whether ssh is giving you a pty in various circumstances. Execute the "tty" command, e.g. "ssh 127.0.0.1 tty". Once you know whether the remote Bash has a pty and that it has been given a command on the command line, you can start sorting out what mode Bash is running in and exactly what "&" does. Dale
