Enable the netutils/discover utility. This example initializes and

starts the UDP discover daemon. This daemon is useful for
|

discovering devices in local networks, especially with DHCP
|

configured devices. It listens for UDP broadcasts which also can
|
||||
include a device class so that groups of devices can be discovered.
|
||||
It is also possible to address all classes with a kind of broadcast

discover.
