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 gener‐
ated. 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.
