SPRAY(8C)               COMMAND REFERENCE               SPRAY(8C)



NAME
     spray - spray packets

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

DESCRIPTION
     The program spray sends a one-way stream of packets to host
     using RPC (Remote Procedure Call), and reports how many
     packets were received by host and reports the transfer rate.
     The host name can be either a name or an internet address.

OPTIONS
     -c count       Specifies 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       Specifies how many microseconds to pause
                    between sending each packet; the default is
                    0.

     -i             Use ICMP (Internet Control Message Protocol)
                    echo packets rather than RPC. Since ICMP
                    automatically echos, this creates a two-way
                    stream.

     -l length      The length parameter is the number of bytes
                    in the Ethernet packet that hold the RPC call
                    message.  Since the data is encoded using XDR
                    (External Data Representation), and XDR only
                    deals with 32 bit quantities, not all values
                    of length are possible; spray rounds up to
                    the nearest possible value.  When length is
                    greater than 1514, 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 (Unreliable Datagram
                    Protocol) headers.
