Check Seeds/Peers on a UDP tracker

[shadyabhi]

I am trying to find the seeds/peers from a UDP tracker but I have not been successful in doing it.
Protocol description -> http://bittorrent.org/beps/bep_0015.htm ... r-protocol

Code: Select all

import struct
import socket
import random

clisocket =  socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
packet = "\x00\x00\x04\x17\x27\x10\x19\x80"
transaction_id = random.randrange(1,65535)
print transaction_id
packet = packet+struct.pack(">i", 0)
packet = packet+struct.pack(">i", transaction_id)

clisocket.sendto(packet, ("tracker.istole.it", 80))
res = clisocket.recv(16)

print struct.unpack(">i", res[12:16])

The both integers printed should be same but when I run this, they aren't.

We use the libtorrent rasterbar library so anything to do with the bittorrent protocol and trackers is dealt with by that.

I managed to do that finally.
