NAME
       spray - spray packets

SYNOPSIS
       /usr/etc/spray [ -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.  This
              requires a raw socket, so you must be "root" to do this.

       -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 and
              minimum value of length is 86 bytes (the size of the RPC and
              UDP headers)
