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.
