spray - spray packets
/usr/etc/spray host [ -c count ] [ -d delay ] [ -i ] [ -l length ]
spray 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 hostname can be either a name or an Internet address.
-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 may microseconds to pause between sending each
packet. The default is 0.
-i Use ICMP echo packets rather than RPC. Since ICMP
automatically echos, 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 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)
ping(1M), sprayd(1M), icmp(7P).
