Overview
bttools is a set of Python tools for experimenting with the BitTorrent protocol. It currently consists of three tools: utptrace, tcptrace and btparser.
utptrace
uTP (uTorrent Transport Protocol, also known as the Micro Transport Protocol) is a reliable transport protocol implemented over UDP. It is used by some BitTorrent clients for file transfer. See BEP 29 for more information.
utptrace is a library for tracing uTP streams. It can be used as a script and fed a PCAP file to trace all uTP streams in it and write them to disk, or it can be fed packets incrementally and receive stream segments in callbacks.
tcptrace
This module is very similar to utptrace, only it works for TCP. Not strictly BitTorrent related but may come handy.
btparser
btparser parses BitTorrent streams. An output file of utptrace can be passed to btparser as an argument. btparser then prints out what it finds in the given stream. Like utptrace, btparser can also be used as a library.
Dependencies
scapy and bencode are needed in order to use any of the above
mentioned libraries. You can get the dependencies by simply running
make (you'll need pip and virtualenv, in addition to make).
The code has been tested with Python 2.7.6.
