Iperf is a commonly-used network testing tool that can create Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) data streams and measure the throughput of a network that is carrying them. Iperf is a tool for network performance measurement written in C. It is a compatible reimplementation of the ttcp program that was developed at the National Center for Supercomputing Applications at the University of Illinois by the Distributed Applications Support Team (DAST) of the National Laboratory for Applied Network Research (NLANR), which was shut down on December 31, 2006, due to termination of funding by the United States' National Science Foundation.
Iperf allows the user to set various parameters that can be used for testing a network, or alternatively for optimizing or tuning a network. Iperf has a client and server functionality, and can measure the throughput between the two ends, either unidirectionally or bi-directionally. It is open-source software and runs on various platforms including Linux, Unix and Windows (either natively or inside Cygwin).
We are the nameless, the only to survive.
We are the winners, who through the years have stayed alive.
We are the ones who never lost sight.
Years go by, and we remain... The few who know what's right.
For years we've waited, never letting go-
Now the time has finally come and all the world will know:
The secret, the message, the outcome of our strife;
Self-reliance, self-destruction... This is fucking life.
The message is blank. It doesn't say a thing.
You're not saving anybody but yourself.
Your life revolves around looking pretty for the "scene".
