21 The in.echod service provides the server-side of the echo protocol.
22 This protocol is used for debugging and bandwidth measurement and is
23 available on both TCP and UDP transports, through port 7.

25
26 The in.echod service is an inetd(1M) smf(5) delegated service. The
27 in.echod detects which transport is requested by examining the socket
28 it is passed by the inetd daemon.
29
30 TCP-based service Once a connection is established, the in.echod
31 echoes any data received from the client back to
32 the client. The server echoes data until the
33 client program terminates the connection.
34
35
36 UDP-based service The in.echod listens for UDP datagrams. When a
37 datagram is received, the server creates a UDP
38 datagram containing the data it received and sends
39 it to the client.
