UDP BitTorrent tracker written in Python 3.5 using co-routines and asyncio.

pybtracker

pybtracker is a UDP BitTorrent tracker written in Python 3.5 using co-routines and the asyncio module. You can use the tracker in a script like this:

import asyncio
from pybtracker import TrackerServer

loop = asyncio.get_event_loop()
tracker = TrackerServer(local_addr=('127.0.0.1', 8000), loop=loop)
asyncio.ensure_future(tracker.start())
try:
    loop.run_forever()
except KeyboardInterrupt:
    loop.run_until_complete(tracker.stop())

It also includes a UDP tracker client:

import asyncio
from pybtracker import TrackerClient

async def announce():
    client = TrackerClient(announce_uri='udp://127.0.0.1:8000', loop=loop)
    await client.start()
    peers = await client.announce(
        b'01234567890123456789',  # infohash
        10000,                    # downloaded
        40000,                    # left
        5000,                     # uploaded
        0,                        # event (0=none)
        120                       # number of peers wanted
    )
    print(peers)

loop = asyncio.get_event_loop()
loop.run_until_complete(announce())

You can run the server independently by running:

$ python -m pybtracker.server -b 127.0.0.1:8000 -O

The client can also be run independently and it provides you with a shell to interact with the server:

$ python -m pybtracker.client udp://127.0.0.1:8000
BitTorrent tracker client. Type help or ? to list commands.

(btrc) help
Documented commands (type help <topic>):
========================================
EOF  announce  connect  help  quit

(btrc) quit
$

If you have installed pybtracker using pip or setup.py, you can also run pybtracker and pybtracker-client instead of using python -m.

pybtracker's Issues

URL format for transmission ?

TRACKERS = [
    "udp://192.168.23.80:9000",
]
tc.change_torrent(trackerAdd=TRACKERS, ids=[t.id])

I've been using rpc to transmission to add the url of the tracker, but it always says

Scrape error: Connection failed - Today 03:09:51 PM

Any idea what the url should look like ?

issue with installation in pip>=10

Hi, your package fails to install with pip>=10 with ImportError: No module named 'pip.req' on line 7 of you setup.py. The solution is on https://stackoverflow.com/a/49867265/867162

Problem with timestamp update in server.py announce

Hello

I checking your code and i found problem with validation in server. problem is

example:
connect -> connid setup datetime

in announce

timestamp is only get function from dict.
last_valid is updated but connid datetime no

i dont understand why is no update connid datetime when peer stay connected.

Exception thrown in TrackerServer after announce

I started the server as told in the README,

from pybtracker import TrackerServer
import asyncio


loop = asyncio.get_event_loop()
tracker = TrackerServer(local_addr=('0.0.0.0',6881),loop=loop)
print(":: TrackerServer initiated ::\n\nStarting server ... ")
asyncio.ensure_future(tracker.start())

try:
	loop.run_forever()
except KeyboardInterrupt:
	loop.run_until_complete(tracker.stop())

But an error comes up when I add a torrent file and as soon as Deluge announces the torrent that uses this tracker 'udp://192.168.42.229:6881' [initially tried with 'udp://127.0.0.1:6881']
What am I doing wrong here 🤔

Here is the output and the error that follows

:: TrackerServer initiated ::
