spray(1M)                   (7 September 1989)                    spray(1M)


   NAME
         spray - spray packets

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

         The following options are available:

         -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 clas of transports.  Defaults to netpath.  See
                        rpc(3N) for a description of supported classes.
