spray - spray packets
/usr/etc/spray [ -c count ] [ -d delay ] [ -i delay ]
[ -l length ] host
This program is available with the Networking software installation
option. Refer to for information on how to install optional software.
spray sends a one-way stream of packets to host using RPC, and reports
how many were received, as well as the transfer rate. The host argu-
ment can be either a name or an internet address.
-c count Specify how many packets to send. The default value of
count is the number of packets required to make the
total stream size 100000 bytes.
-d delay Specify how many microseconds to pause between sending
each packet. The default is 0.
-i delay Use ICMP echo packets rather than RPC. Since ICMP auto-
matically echos, this creates a two way stream.
-l length The length parameter is the numbers of bytes in the Eth-
ernet 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).
