NAME
     spray - spray packets

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

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

OPTIONS
     -c count  Specifies 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  Specifies 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)
