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  generates  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 containing a random number of
			    ASCII characters (ranging from 0  to  512  charac‐
			    ters). 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.
