问题 Does libtorrent support python3 now? if supported how to install it . I want to code a DHT Crawler with python3 , i don't know why my code alaways got Connection reset by peer error , so i want to use libtorrent , if there are another lib , i'm happy to use it . My biggest problem is , conversing the infohash to torrent file . Could it be a code problem? class Crawler(Maga): async def handler(self, infohash, addr): fetchMetadata(infohash, addr) def fetchMetadata(infohash, addr, timeout=5):

问题 Sometimes I receive this strange responses from other nodes. Transaction id match to my request transaction id as well as the remote IP so I tend to believe that node responded with this but it looks like sort of a mix of response and request d1:q9:find_node1:rd2:id20:.éV0özý.?tj­N.?.!2:ip4:DÄ.^7:nodes.v26:.ï?M.:iSµLW.Ðä¸úzDÄ.^æCe1:t2:..1:y1:re Worst of all is that it is malformed. Look at 7:nodes.v it means that I add nodes.v to the dictionary. It is supposed to be 5:nodes. So, I'm lost.

问题 Question Taken from here: https://groups.google.com/forum/#!topic/byu-cs-460-computer-networking/hpESI0NapmY "I was thinking about how Distributed Hash Tables store data. I understand that each node is given an identifier and that the data is then stored on the node whose identifier is the closest successor to its (the data's) hash value. I also understand that when nodes join or leave the network, the data gets transferred to reflect the new set of nodes present in the network. What I don't

问题 In my new weekend project I decided to write an bittorrent client from scratch, no ready to use libraries at all. After two days looking for documentation I'm already about to give up :smile:. I know there are the BEPs, but they are far from enough to understand all the specification. After reading a lot more I think the tracker and peer protocols seems to be old and easy to understand/implement (yes, I know, to write a good code with balance, peer selection, optimizations, this is not easy

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . I'm looking for recommendations for a simple open source implementation of a Distributed Hash Table in Java to play around with. No fancy features, just for learning purposes, no production functionality needed. It should be simple to set up (e.g. 1 physical machine with n-JVMs) and well documented preferably

问题 In the Kademlia paper, the last paragraph of section 2.4 states that in order to properly handle highly unbalanced trees... Kademlia nodes keep all valid contacts in a subtree of size at least k nodes, even if this requires splitting buckets in which the node's own ID does not reside. However, the previous section of the paper seem to state that if a k-bucket already has k elements, that any further additions in to that k-bucket require removing the stalest node (pinging it first to see if

问题 I know about NAT traversal and about STUN, TURN and ICE and its use. I want to know whether these are implemented in peer to peer file sharing application like bittorrent. Whether trackers facilitate peers behind NATs to communicate with each other by helping in creating direct connection using STUN or relay through TURN. In the case of Distributed Hash Table(DHT) how one peer would communicate with other peer behind NAT ? 回答1: BitTorrent does not need to connect to any particular member in a

问题 Can I generate torrent file that already has peers inside without using trackers, open trackers, dht and peer exchange? If yes, how can I do that? The reason I want to do that, is that I want to get peers by DHT and pass that peers to another torrent client that do not supports DHT or peer exchange, and cannot get peers without trackers. I found this, but I don't understand what is nodes, and if it's what I am searching for. http://www.bittorrent.org/beps/bep_0005.html#torrent-file-extensions

问题 I want to setup a Kademlia network to connect peers and build a p2p network. I'm going to distribute processing power of nodes within the network. For network I found this Kademlia Java implemented Setup from git. https://github.com/JoshuaKissoon/Kademlia I want to know how to setup this and use to implement the network. I found that JKademliaNode kad1 = new JKademliaNode("Node1", new KademliaId("ASF45678947584567467"), 7574); JKademliaNode kad2 = new JKademliaNode("Node2", new KademliaId(

问题 Following on from this question about DHTs in Python, my question is the same except that I'm developing on Python 3.x - I only want to know about implementations of the DHT concept which are known to work with Python 3. There seem to be plenty of DHT products, for example Khashmir, however as far as I'm aware nobody has bothered to make these available to Python 3.x. 回答1: I don't think you'll get simultaneous 2.6 and 3.x support - that is not what Guido is recommending. To do that they'd
