execute commands as su on remote server

[Laura Creighton]

I haven't tried this but fabric looks encouraging:

From http://docs.fabfile.org/en/latest/api/core/operations.html#fabric.operations.run

 fabric.operations.run(*args, **kwargs)

    Run a shell command on a remote host.

    ...

    Any text entered in your local terminal will be forwarded to the
    remote program as it runs, thus allowing you to interact with
    password or other prompts naturally

    ...

    You may pass pty=False to forego creation of a pseudo-terminal on
    the remote end in case the presence of one causes problems for the
    command in question.
