My new tool simple_tcp_stats.py is a Python program that reads pcap files and produces simple statistics for each TCP connection.
For the moment, it calculates the entropy of the data (without packet reassembling) of each TCP connection (both directions) and reports this with a CSV file:
ConnectionID;head;Size;Entropy
