    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 transfer rate. The host argument
           can be either a name or an Internet address.
    
    
           spray  is  not  useful as a networking benchmark, as it uses unreliable
           connectionless transports, UDP for example. spray can  report  a	 large
           number  of  packets dropped when	the drops were caused by spray sending
           packets faster than they	can be buffered	locally, that is,  before  the
           packets get to the network medium.
    
    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.
    
    
           -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.
    
    
           -t nettype    Specify  class  of	 transports. Defaults to  netpath. See
    		     rpc(3NSL) for a description of supported classes.
