in.discardd(1M) System Administration Commands in.discardd(1M)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(1M) and
smf(5).
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(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.

rpc.sprayd(1M) System Administration Commands rpc.sprayd(1M)NAME
rpc.sprayd, sprayd - spray server
SYNOPSIS
/usr/lib/netsvc/spray/rpc.sprayd
DESCRIPTION
rpc.sprayd is a server that records the packets sent by spray(1M). The rpc.sprayd daemon may be started by inetd(1M) or listen(1M).
The service provided by rpc.sprayd is not useful as a networking benchmark as it uses unreliable connectionless transports, (udp for exam-
ple). It can report a large number of packets dropped when the drops were caused by the program sending packets faster than they can be
buffered locally (before the packets get to the network medium).

The rpc.sprayd service is managed by the service management facility, smf(5), under the service identifier:
svc:/network/rpc/spray:default
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). Responsibil-
ity for initiating and restarting this service is delegated to inetd(1M). Use inetadm(1M) to make configuration changes and to view config-
uration information for this service. The service's status can be queried using the svcs(1) command.

Hi all,
When using netcat to transfer the data over socket, if no connection is established, how long will netcat keep the data; will it discard the "oldest" data ?
