IN.DISCARDD(8) Maintenance Commands and Procedures IN.DISCARDD(8)

NAME

in.discardd - UDP or TCP discard protocol service

SYNOPSIS

in.discardd


FMRI svc:/internet/discard:default

DESCRIPTION

FMRI stands for Fault Management Resource Identifier. It is used to
identify resources managed by the Fault Manager. See fmd(8) and
smf(7).


The in.discardd service provides the server-side of the discard
protocol. This protocol is used for debugging and bandwidth
measurement and is available on both TCP and UDP transports through
port 9.


The in.discardd service is an inetd(8) smf(7) delegated service. The
in.discardd detects which transport is requested by examining the
socket it is passed by the inetd daemon.


The discard service simply throws away any data it receives from the
client.

TCP-based service
Once a connection is established, the
in.discardd discards any data received. No
response is generated. The connection remains
open until the client terminates it.


UDP-based service
The in.discardd listens for UDP datagrams. When
a datagram is received, the server discards it.
No response is sent.
