in.echod
in.echod(1M) System Administration Commands in.echod(1M)NAME
in.echod - UDP or TCP echo protocol service daemon
SYNOPSIS
in.echod
FMRI
svc:/internet/echo:default
DESCRIPTION
FMRI stands for Fault Management Resource Identifier. It is used to identify resources managed by the Fault Manager. See fmd(1M) and
smf(5).
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.
TCP-based service
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.
UDP-based service
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.
