I have turned off portmap, that is sunrpc sorted.  I am not too sure 
what you mean by xdm and gdm though.  There are directories for both in 
the /etc/X11 directory and I have looked through the config files in 
both directories but can't find anything relating to listening on ports 
although I might have missed it.  Any ideas on finding this information 
out and then once I have done that, stopping it from listening?

Many thanks
Will.
