NAME
       spray - spray packets

SYNOPSIS
       /usr/sbin/spray [-c count] [-d delay] [-l length]
	    [-t nettype] host

DESCRIPTION
       spray  sends  a	one-way  stream  of  packets to host using RPC, and reports how many were
       received, as well as the transfer rate. The host argument can  be  either  a  name  or  an
       Internet address.

       spray is not useful as a networking benchmark, as it uses unreliable connectionless trans-
       ports, UDP for example. spray can report a large number of packets dropped when the  drops
       were  caused  by  spray sending packets faster than they can be buffered locally, that is,
       before the packets get to the network medium.

OPTIONS
       -c count      Specify how many packets to send. The default value of count is  the  number
		     of packets required to make the total stream size 100000 bytes.

       -d delay      Specify  how  many  microseconds  to  pause between sending each packet. The
		     default is 0.

       -l length     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 quantities, 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 Ether-
		     net packet size. The default value of length is 86 bytes, the  size  of  the
		     RPC and UDP headers.

       -t nettype    Specify  class  of  transports.  Defaults	to   netpath. See rpc(3NSL) for a
		     description of supported classes.
