IN.ECHOD(1M) Maintenance 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.
