8 in.echod \- UDP or TCP echo protocol service daemon
17 FMRI \fIsvc\fR:/internet/echo:default
23 FMRI stands for Fault Management Resource Identifier. It is used to identify
24 resources managed by the Fault Manager. See \fBfmd\fR(8) and \fBsmf\fR(5).
27 The \fBin.echod\fR service provides the server-side of the echo protocol. This
28 protocol is used for debugging and bandwidth measurement and is available on
29 both TCP and UDP transports, through port 7.
32 The \fBin.echod\fR service is an \fBinetd\fR(8) \fBsmf\fR(5) delegated
33 service. The \fBin.echod\fR detects which transport is requested by examining
34 the socket it is passed by the \fBinetd\fR daemon.
38 \fBTCP-based service\fR
41 Once a connection is established, the \fBin.echod\fR echoes any data received
42 from the client back to the client. The server echoes data until the client
43 program terminates the connection.
49 \fBUDP-based service\fR
52 The \fBin.echod\fR listens for UDP datagrams. When a datagram is received, the
53 server creates a UDP datagram containing the data it received and sends it to
