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).
