How did you install NFS as it is featured by default...
I misread it
because it sounds wrong. You cannot install NFS, you can only activate it
and configure it
The NFS has nothing to do with FTP either as far as i know.
Check FTP is enabled and use the user "nmt". I remember reading that is
the correct username... If the password fails, try setting a new password in
the setup for the FTP access. I believe this is possible by now... (but i could be wrong as I see too many players...)
