Subject: RE: Calling SSH from Expect - URGENT

Is WS007594 a Win/cygwin box, or a straight linux box??
I can not get the expect script to work under cygwin, but it
does run under debian/linux.  That is why I suspect that either 
the cygwin version of ssh isn't playing nice, or the cygwin version
of expect isn't attaching to the ssh stdin correctly.  I don't know
if I will have more time to debug, but I might look into it later.
