DESCRIPTION

The spray command sends a one-way stream of packets to host using RPC, and then
reports how many were received by host and what the transfer rate was.  The
host name can be either a name or an internet address.

FLAGS

-c count
     Specifies how many packets to send.  The default value of count is the
     numbers 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 echo packets rather than RPC.  Since ICMP automatically echoes,
     this creates a two way stream.

-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 possible,
     and spray rounds up to the nearest value.  When length is greater than
     1514, then the RPC call can no longer be encapsulated in one Ethernet
     packet, so the length field is 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).
