bittorrent

Is there any good library for Ruby to work with BitTorrent trackers? To download or seed files. There's a rubytorrent library on rubyforge, but it was last updated in 2005 and doesn't seem like working anymore. fingerman see lib-torrent ruby... https://github.com/maran/libtorrent-ruby I'm not sure if this is what you want. ProphetZarquon Also see this post which contains some potentially useful comments as well, including a Ruby wrapper for the Transmission API using RPCs. My experience with libtorrent derived clients has been very positive, I would like to see something new here. (I prefer

I was just downloading a new distro of linux using uTorrent, and started to wonder how uTorrent (and other bittorrents) send files to eachother through NAT routers? They obviously use the trackers to get introduced, but how do they pass info to eachother? Is there a whitepaper on this? I couldn't find one :/ Thanks Most of the time, they don't. I have a restricted network, and every time I run my torrent program it warns me that some of the ports/functionality required is not available to me. If one party has a restricted network and another has an open network, the restricted client will

When you place a .torrent file for download in your website, how can you get the number of Seeds & Peers for that Torrent and inform the user of them? You have to contact the tracker(s) that is shown in the torrentfile. If the tracker support "scraping" that is probably the request you want. Otherwise its up to the tracker to decide how many peers it wants to return to you, and you have no idea if those peers is a seed or leech before contacting them. The torrentfile is in bencoded format, look for the bdecode php library to easily parse the info. Provide the infohash you get from the pieces

I'm trying to implement a bittorent client and I got stuck at the part were I succesfully connected to a peer but I don't know how to communicate with the peer. I managed to decode the torrent metadata file, I succesfully got all the info from there, I connected to a peer with TCP, I send the handshake message, I receive the handshake message back from the peer, but after that I don't receive any message from the peer (I was expecting the have messages). I tried sending an unchoke message to the peer and I started receiving some data but I don't know how to understand that data. This is what I

Is there any way to extract metadata from a torrent file using Java? Take a look at this . And Java Bittorrent API . 来源： https://stackoverflow.com/questions/3437420/extracting-metadata-from-torrents-with-java

How can I calculate the hash value of a torrent file using Java? Can I calculate it using bencode ? BalusC Torrent files are hashed using SHA-1 . You can use MessageDigest to get a SHA-1 instance. You need to read until 4:info is reached and then gather the bytes for the digest until remaining length minus one. Note : This implementation works for most torrents, but the .torrent file is not guaranteed to end with the info key. File file = new File("/file.torrent"); MessageDigest sha1 = MessageDigest.getInstance("SHA-1"); InputStream input = null; try { input = new FileInputStream(file);

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 = torrentstub[counter]) > -1;) { array[test++] = data; counter++; } std::cout << array << std::endl; //SHA

How does one calculate the info_hash parameter ? Aka the hash corresponding to the info dictionar?? From official specs: info_hash The 20 byte sha1 hash of the bencoded form of the info value from the metainfo file. Note that this is a substring of the metainfo file. This value will almost certainly have to be escaped. Does this mean simply get the substring from the meta-info file and do a sha-1 hash on the reprezentative bytes?? .... because this is how i tried 12 times but without succes meaning I have compared the resulting hash with the one i should end up with..and they differ ..that +
