DESCRIPTION

16       FMRI  stands  for  Fault  Management Resource Identifier. It is used to
17       identify resources managed  by  the  Fault  Manager.  See  fmd(1M)  and
18       smf(5).

21       The  in.chargend service provides the server-side of the character-gen‐
22       erator protocol. This protocol is used for debugging and bandwidth mea‐
23       surement  and is available on both TCP and UDP transports, through port
24       19.
25
26
27       The in.chargend service is an inetd(1M) smf(5) delegated  service.  The
28       in.chargend  detects  which  transport  is  requested  by examining the
29       socket it is passed by the inetd daemon.
30
31       TCP-based service    Once a connection is established, the  in.chargend
32                            generates  a  stream of data. Any data received is
33                            discarded. The server  generates  data  until  the
34                            client  program  terminates  the  connection. Note
35                            that the data flow is limited by TCP flow  control
36                            mechanisms.
37
38
39       UDP-based service    The  in.chargend listens for UDP datagrams. When a
40                            datagram is received, the server generates  a  UDP
41                            datagram in response containing a random number of
42                            ASCII characters (ranging from 0  to  512  charac‐
43                            ters). Any received data is ignored.
44
45
46
47       The  in.chargend  data consists of a pattern of 72 character lines con‐
48       taining the printable, 7-bit ASCII characters. Each line is  terminated
49       with a carriage return and a line feed character.
