First, you don't need the DenyUsers line. If you specify AllowUsers then
ONLY the users on AllowUsers can login. But you must set the
PermitRootLogin to yes. Then your AllowUsers rule will work, and only
hosts in the 192.17 network will be able to login as root. But why you
need to login directly as root?
