[Mimedefang] watch-mimedefang

I can ssh from my windows instance of cygwin to the mimedefang server.  I
also established a trust relationship by exchanging ssh keys.  I do that all
the time to automate ssh tasks.  However, for cygwin, it keeps defaulting to
my windows user and not "root" and that's the problem.  I can override it if
I type out the ssh command at the command prompt (ssh root@<ip>) but when
watch-mimedefang runs, it uses the windows user.  If I could figure out how
to run cygwin with root user I think it would work.

The server themselves don't need a GUI - but having one on the machine where
have tools to manage them will make your work easier even if all you do is
run a
bunch of xterms with ssh to the others.

The nature of X is that you can run single applications in a remote window,
all you need on the servers are the basic X libs, and they are only loaded
you run a graphic application.  The real overhead is in the desktop
which can be elsewhere.

Most of the time goes into building and installing all the local fonts.  How
it fail for you?  Did 'startx' give you the X screen with some open xterms?
Could you 'ssh -Y' to your server from one of them?  If you got that far,
starting a remote program should have worked.  You should even be able to
putty on the windows side if you set up the X tunnel option - I've forgotten
you need to set up the DISPLAY environment.
