NAME
     spray - sprays packets

SYNOPSIS
     spray host [-c count] [-l length]

ARGUMENTS
     -c count
          Specifies the number of packets which make up the
          stream packet.  The default value of count is the
          number of packets required to make the total stream
          size 100,000 bytes.

     host Specifies the host to which a stream of packets is
          sent.  The host can be either a name or an Internet
          address.

     -l length
          Specifies the number 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.

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 spray command will round 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 the
     Ethernet packet size.  The default value of length is 86
     bytes (the size of the RPC and UDP headers).
