    NOTE: to get the routing of the 255.255.255.255 broadcasts to work
    under QNX, you need to issue the following command before starting
    the daemon:

    	route add -interface 255.255.255.0 <hostname>

    where <hostname> is replaced by the hostname or IP number of the
    machine that dhcpd is running on.
