in.echod - UDP or TCP echo protocol service daemon
FMRI stands for Fault Management Resource Identifier. It is used
to identify resources managed by the Fault Manager. See fmd(1M) and
The in.echod service provides the server-side of the echo
protocol. This protocol is used for debugging and bandwidth measurement and
is available on both TCP and UDP transports, through port 7.
The in.echod service is an inetd(1M) smf(5)
delegated service. The in.echod detects which transport is requested
by examining the socket it is passed by the inetd daemon.
Once a connection is established, the in.echod
echoes any data received from the client back to the client. The server echoes
data until the client program terminates the connection.
The in.echod listens for UDP datagrams. When a
datagram is received, the server creates a UDP datagram containing the data it
received and sends it to the client.
