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-generator  protocol.  This  protocol  is  used for
     debugging and bandwidth measurement 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  gen-
         erates a stream of data. Any data received is discarded.
         The server generates data until the client program  ter-
         minates  the connection. Note that the data flow is lim-
         ited 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  characters). Any
         received data is ignored.



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