spray(8)						      System Manager's Manual							  spray(8)

NAME

       spray - Spray packets

SYNOPSIS

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

OPTIONS

       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.  Specifies how many microseconds to pause between sending each packet.  The default is 0.  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 quanti-
       ties, 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).  Specify class of transports.  Defaults  to  netpath.
       See rpc(3) for a description of supported classes.

DESCRIPTION

       The  spray  command  uses  RPC to send a one-way stream of packets to the specified host and reports how many were received, as well as the
       transfer rate.  The host argument can be either a name or an Internet address.

       A remote host only responds if it is running the sprayd daemon, which is normally started up from inetd(8).

       The spray command is not useful as a networking benchmark.  The spray command can report a large number of packets dropped when	the  drops
       were caused by spray sending packets faster than they can be buffered locally (before the packets get to the network medium).
