NAME
       spray - spray packets

SYNOPSIS
       /usr/etc/spray host [ -c count ] [ -d delay ] [ -i ] [ -l length ] host

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

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

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

       -i     Use ICMP echo packets rather than RPC.  Since ICMP automatically
	      echos, this creates a two way stream.

       -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 Ethernet packet size.  The  default  value  of
	      length is 86 bytes (the size of the RPC and UDP headers)
