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 pack-
                    ets 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 pos-
                    sible,  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 net-
                    path.   See rpc(3N) for a description of sup-
                    ported classes.
