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 hostname 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)
