If firewalls don't accept incoming connections by default how do p2p networks work?

由 蹲街弑〆低调 提交于 2020-01-22 05:33:10
问题 If firewalls block all incoming connections by default how do p2p technologies work? Like torrents, how do you connect to everyone who shares a file and get the information from them? Does it go through a relay server or something? 回答1: I'm not up on everything about BitTorrent, as I am about general P2P connectivity techniques. Typically clients in a P2P network rendezvous on a common signaling server (e.g. SIP, XMPP, tracking server, web site) to exchange IP addresses,other meta data, and

Can QUIC streams be improved upon for file transfer?

由 こ雲淡風輕ζ 提交于 2020-01-16 16:48:11
问题 If I understand, QUIC exists to multiplex multiple streams over the same UDP channel, including same key exchange. QUIC also has an unreliable transport mode for VoIP, etc. https://datatracker.ietf.org/doc/draft-pauly-quic-datagram/ Has anyone considered a “file" transfer mode for QUIC that uses either this unreliable mode or another "less" reliable mode? Would file transfer benefit much from even less ordered delivery than a QUIC stream supports? There is a bittorrent variant µTP (BEP-29)

How PEX protocol (Magnetic links) finds it first IP?

由 纵饮孤独 提交于 2020-01-09 04:22:30
问题 I'm trying to understand how can a magnetic link work, as I've read they use DHT and PEX to get the peers, but if I'm a new node in the network how can I find peers with only the hash of the file?! Doesn't it always require a link to a known host? Thanks 回答1: The bittorrent DHT can be bootstrapped in many ways. It just needs the IP and Port of any other reachable DHT node out there. Current clients generally use several of the following strategies: bootstrap from a cache of long-lived nodes

download content torrent files point to in python3

由 China☆狼群 提交于 2020-01-06 04:07:56
问题 Perhaps I'm misunderstanding how .torrent files work, but is there a way in python to download the actual referenced content the .torrent file points to that would be downloaded say using a torrent client such as utorrent, but from the shell/command line using python? The following works for simply downloading a .torrent file and sure I could open the torrent client as well do download the .torrent, but I'd rather streamline the process in the command line. Can't seem to find much online

How does ThePirateBay know the number of seeders for its torrents?

由 点点圈 提交于 2020-01-02 09:59:41
问题 How do websites like ThePirateBay.org work? I heard that the age of trackers is pretty much over, so I guess they extract data from DHT. I wrote a simple DHT scraper, but it was pretty slow to query the servers - does TPB have its own DHT nodes they sniff on? Do they verify whether the peers actually have data? 回答1: I'm not staff on TPB (or any other torrent index site) and have no exact information how they do it, but my best guess is that they regulary fetch a full scrape from the (working)

Create torrent hash info

问题 how do I generate torrent hash info on torrent files. I have been taking a look on this example: How to calculate the hash value of a torrent using Java and am trying to convert it to C++. This is the code I have so far: void At::ReadTorrent::TorrentParser::create_hash(std::string torrentstub) { std::string info; int counter = 0; while(info.find("4:info") == -1) { info.push_back(torrentstub[counter]); counter++; } unsigned char array[torrentstub.size()]; int test = 0; for(int data; (data =

Torrent DHT udp

问题 Im trying to get access to a Torrent DHT network, and im having a hard time figuring out howto get access to the "entry" node in DHT. How does a DHT in a Bittorent client get "bootstrapped"? Describes that a couple of standard entry nodes could be used router.bittorrent.com and router.utorrent.com running on port 6881 (UDP). AND http://www.bittorrent.org/beps/bep_0005.html describes the protocol on howto interact with a DHT server. But if i send a simple UDP message to router.utorrent.com
