spray(1M) spray(1M) NAME
spray - spray packets SYNOPSIS
count] delay] length] nettype] host DESCRIPTION
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. is not useful as a networking benchmark, as it uses unreliable connectionless transports, UDP, for example. can report a large number of packets dropped when the drops were caused by sending packets faster than they can be buffered locally, that is, before the packets get to the network medium. Options recognizes the following options and command-line arguments: 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. Specify how many microseconds to pause between sending each packet. The default is 0. Specify the number 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 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. In that case, the length field no longer has a simple correspondence to the 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 See rpc(3N) for a description of supported classes. AUTHOR
