IN.ECHOD(8) Maintenance Commands and 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.
