NAME
       in.chargend - UDP or TCP character generator service daemon

SYNOPSIS
       in.chargend

       FMRI
       svc:/internet/chargen: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.chargend service provides the server-side of the character-gen‐
       erator protocol. This protocol is used for debugging and bandwidth mea‐
       surement	 and is available on both TCP and UDP transports, through port
       19.

       The in.chargend service is an inetd(1M) smf(5) delegated	 service.  The
       in.chargend  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.chargend  generates  a
	   stream  of  data. Any data received is discarded. The server gener‐
	   ates data until the client program terminates the connection.  Note
	   that the data flow is limited by TCP flow control mechanisms.

       UDP-based service

	   The	in.chargend  listens  for  UDP	datagrams.  When a datagram is
	   received, the server generates a UDP datagram in response  contain‐
	   ing	a  random  number  of  ASCII characters (ranging from 0 to 512
	   characters). Any received data is ignored.

       The in.chargend data consists of a pattern of 72 character  lines  con‐
       taining	the printable, 7-bit ASCII characters. Each line is terminated
       with a carriage return and a line feed character.
