host
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 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)
