Please don't top post.  In this mailing list, the convention is to put
your remarks after the part you're quoting (which usually isn't the
entire message).  That way, if the context gets complex, it's easier to
see who wrote what, and in what order.

Did you try it the way I suggested above?  Make it work in ssh, then
worry about how python can build that command string.

Since there's no  os.exec, it was just an brain-hiccup on my part.



So, back to the problem.  Once you've got it working in ssh, then we can
figure how to make os.exec, or other python execution mechanism, work.
