spray(8) System Manager's Manual spray(8)NAME
spray - Spray packets
SYNOPSIS
/usr/sbin/spray [-c count] [-d delay] [-l length] [-t nettype] host
OPTIONS
Specifies how many packets to send. The default value of count is the number of packets required to make the total stream size 100000
bytes. Specifies how many microseconds to pause between sending each packet. The default is 0. The length parameter is the numbers of
bytes in the Ethernet packet that holds the RPC call message. Since the data is encoded using XDR, and XDR only deals with 32 bit quanti-
ties, not all values of length are possible, and spray rounds up to the nearest possible value. When length is greater than 1514, then the
RPC call can no longer be encapsulated in one Ethernet packet, so the length field no longer has a simple correspondence to Ethernet packet
size. The default value of length is 86 bytes (the size of the RPC and UDP headers). Specify class of transports. Defaults to netpath.
See rpc(3) for a description of supported classes.
DESCRIPTION
The spray command uses RPC to send a one-way stream of packets to the specified host and reports how many were received, as well as the
transfer rate. The host argument can be either a name or an Internet address.
A remote host only responds if it is running the sprayd daemon, which is normally started up from inetd(8).
The spray command is not useful as a networking benchmark. The spray command can report a large number of packets dropped when the drops
were caused by spray sending packets faster than they can be buffered locally (before the packets get to the network medium).

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.

Hello,
I am currently trying to limit incoming UDP length 20 packets on a per IP basis to 5 a second using IPTables on a Linux machine (CentOS 5.2).
