NAME
spray - spray packets
SYNOPSIS
/usr/etc/spray host [ -c count ] [ -d delay ] [ -i ] [ -l
length ]
DESCRIPTION
spray sends a one-way stream of packets to host using rpc,
and reports how many were received, as well as the the
transfer rate. The host argument can be either a name or an
internet address.
OPTIONS
-c count
Specify 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
Specify 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 possi-
ble, 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) The
default value of lnth is 86 bytes (the size of the rpc
and udp headers), and the value of cnt is the number of
packets required to make the total stream size 10000
bytes. The host name can be either a name or an inter-
net address.
