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.
