Sorry, how does one do that?  Do you mean 

       $ sudo /etc/init.d/NetworkManager stop
       $ sudo NetworkManager --no-daemon?

       NetworkManager <information>  starting...

       NetworkManager: <WARNING>         nm_dbus_init ():
       nm_dbus_init() could not acquire the NetworkManager service as
       it is already taken (ret=3).  Is the daemon already running?
       
       NetworkManager: <ERROR> [1155929108.205204]  main ():
       nm_dbus_init() failed, exiting.  Either dbus is not running, or
       the NetworkManager dbus security policy was not loaded.
