 NAME    [Toc]    [Back]
      spray - spray packets

 SYNOPSIS    [Toc]    [Back]
      /usr/sbin/spray host [-c count] [-l length]

 DESCRIPTION    [Toc]    [Back]
      spray sends a one-way stream of packets to host using RPC, 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.

    Options    [Toc]    [Back]
      spray recognizes the following options and command-line arguments:

           -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.

           -l length      The number of bytes in the Ethernet packet holding
                          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.
                          The spray command rounds up to the nearest
                          possible value.  When length is greater than the
                          size of an Ethernet packet, the system breaks the
                          datagram into multiple Ethernet packets.  The
                          default value of length is 86 bytes (the size of
                          the RPC and UDP headers).
