in.chargend(1M) System Administration Commands in.chargend(1M)NAMEin.chargend - UDP or TCP character generator service daemonSYNOPSISin.chargend FMRI svc:/internet/chargen:defaultDESCRIPTIONFMRI 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.ATTRIBUTESSee attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcnsu | +-----------------------------+-----------------------------+ |Interface Stability |Evolving | +-----------------------------+-----------------------------+SEE ALSOinetd(1M), attributes(5), smf(5) RFC 864 SunOS 5.10 23 Aug 2004 in.chargend(1M)
