2nd question of the day: Xsecurity

["Chris Evans" <c.evans@sghms.ac.uk>]

I am enormously pleased to have my Email lists and WWW 
service now running fine on a very cheap (reconstruction job!) 
Debian box in my old office with SSL-telnet giving me what feels 
like very secure access for any work I have to do on it.  I'd like to 
use Emacs from within X on my home machine when I do have to 
telnet in for work but I'm getting a refusal to give Emacs X client 
access to the server on the remote machine (if I've got the 
server/client naming the right way round).   My questions are:

1) The remote machine isn't running X at the time, do I need to 
leave it with X running or can I assume it will launch it?  (It does 
have a very limited VGA server up and running there.)

2) How do I set security in X so as minimise any possible holes but 
to give me this access?  I have looked through the documentation 
but can't see anything pertinent.  A man page suggests there is 
another on "Xsecurity" and the Xhost man page suggests _that_ 
isn't what I need.  Please will someone point me at the right 
documentation?

TIA

Chris
