This is the command tcpspray that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
tcpspray - print average throughput for a tcp connection
SYNOPSIS
tcpspray [ -v ] [ -e ] [ -h ] [ -b blksize ] [ -n nblks ]
[ -f filename ] hostname
DESCRIPTION
tcpspray sends data to either the discard or echo TCP service on the specified host and
prints the average throughput.
OPTIONS
-v Prints a dot for each block sent. Will also print a backspace for each
block received in echo mode. Note: the I/O required for this option will
affect the throughput rates.
-e Use the TCP echo service instead of discard (the default) and print
throughput rates for both transmission and reception.
-h Print a usage description.
-b blksize Sets the size of a block (the internal buffer) in bytes. Defaults to 1024.
-n nblks Sets the number of blocks to transfer. Defaults to 100.
-f filename Copy the contents of the specified file into the internal buffer (sized by
-b option). The buffer is zeroed by default. If the file is larger than
the buffer, only the first blksize bytes will be used. If the file is
smaller than the buffer, the remaining bytes are zeroed.
This option is useful in determining the relationship of the data
transferred to throughput. E.g., if data compression is used on any of the
intermediate links comprising the TCP connection, preloading the buffer
with a text file will produce greater throughput than with a file that has
already been compressed.
-d delay Sets the time in microseconds to wait between successive buffer
transmissions. The default is no delay.
