       NAME
             spray - spray packets

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

       DESCRIPTION
             The spray command sends a one-way stream of packets to host
             using RPC, and reports how many were received, as well as the
             transfer rate.

       USAGE
             The host argument can be either a name or an Internet address.

          Options
             spray takes the following 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 Ethernet 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(3N) for a description of
                            supported classes.
