in.discardd(1M) System Administration Commands in.discardd(1M)NAMEin.discardd - UDP or TCP discard protocol service
SYNOPSISin.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(1M) and
smf(5).
The in.discardd service provides the server-side of the discard proto‐
col. 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(1M)smf(5) 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.
