in.chargend(1M) 					  System Administration Commands					   in.chargend(1M)

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 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 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.
