+'''What it detects'''
+
+   * Detects the presence of a DPI device that sends TCP RST packets when it detects an offending connection
+
+'''Inputs'''
+
+   * A list of IP:port pairs to be tested.
+
+'''Experiment'''
+
+   * A TCP Connect scan is made to the remote IP:PORT
+
+'''Control'''
+
+   * If for the TCP connect we get back a RST packet then there is a DPI device injecting RST packets.
+ 
+'''Output'''
+
+   * What IP:ports are being blocked using this technique.
+
+
+'''Notes'''
+
+This is the kind of censorship that is happening in china as illustrated in this paper: http://www.cl.cam.ac.uk/~rnc1/ignoring.pdf
