IN.ECHOD(8) Maintenance Procedures IN.ECHOD(8)
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(8) and
smf(7).
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(8) smf(7) 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.
