Addressing the need to know what such middleboxes do, we introduce a tool called fling (``flexible ping''). fling can carry out (almost) any kind of protocol dialogue between a server and a client based on a simple specification in a json and a pcap file, and identify what middleboxes do to the packets of the dialogue. This fills a gap in the state of the art, where other tools that control both ends of a path are either limited in some form or have to be updated for every new test. We present results from small-scale tests that prove the flexibility of fling, which is a prerequisite for our next step: development of a large-scale measurement platform.
