NAME
spray — spray packets
SYNOPSIS
/usr/sbin/spray
host
[-c
count]
[-l
length]
DESCRIPTION
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
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).
