Manual page for SPRAY(8C)

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 [a manual with the abbreviation INSTALL] 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 argument 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 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).
