SPRAY(8C)                                                            SPRAY(8C)



NAME
       spray - spray packets

SYNOPSIS
       /usr/etc/spray [ -c count ] [ -d delay ] [ -i delay ]
            [ -l length ] host

AVAILABILITY
       This  program  is  available  with the Networking software installation
       option.  Refer to for information on how to install optional software.

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

       -i delay       Use ICMP echo packets rather than RPC.  Since ICMP auto-
                      matically echos, this creates a two way stream.

       -l length      The length parameter is the numbers of bytes in the Eth-
                      ernet 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).
