21 The in.discardd service provides the server-side of the discard proto‐
22 col. This protocol is used for debugging and bandwidth measurement and
23 is available on both TCP and UDP transports through port 9.
24
25
26 The in.discardd service is an inetd(1M) smf(5) delegated service. The
27 in.discardd detects which transport is requested by examining the
28 socket it is passed by the inetd daemon.

31 The discard service simply throws away any data it receives from the
32 client.
33
34 TCP-based service Once a connection is established, the in.discardd
35 discards any data received. No response is gener‐
36 ated. The connection remains open until the client
37 terminates it.
38
39
40 UDP-based service The in.discardd listens for UDP datagrams. When a
41 datagram is received, the server discards it. No
42 response is sent.
