Bittorrent Files Hace Stopped Downloading bittorrent files hace stopped downloading Why Some Torrents Don’t Download? A torrent that doesn’t start downloading or one that suddenly stops can be very frustrating. You check your Internet connection, the cables, and everything looks good. So what can be the reasons for those torrents that don’t seem to work? Some Torrents Don’t Download. The main reason behind a torrent file that doesn’t even start downloading is the lack of seeders and peers. In other words, there is no one seeding that file, meaning there’s no place where you can download it from. That’s why it’s very important that you have a look at the number of seeders and peers every time you start a new download. Seeders are the users who already finished downloading and are only sharing. The peers are the ones like you, the ones who are downloading and uploading at the same time. Some Files Suddenly Stop Downloading. This is another common scenario. We’ve all been there when a torrent stops at some moment, such as 99%. That usually happens when there are only peers, but no seeders . If you think about it, it makes total sense. The peers have many parts of the torrent in common, and they will share those between them. But because there are zero seeders, no one has the entire file , and everyone will share the same parts and stop in the same percentage point. A Dead Torrent. Both of the situations we just saw are what users in the community call a “dead torrent”. Since there are no seeders and, even if there are peers, they do not have the entire amount of parts between them to make it a complete file, the torrent “died”. If you were wondering if it’s worth seeding torrents, then this is the answer to your question. Seeding helps to maintain healthy torrents. What About Slow Torrents? This problem is often related to the situation we discussed before. In this case, what generally happens is that there are many people downloading, but only a few seeding. The Leecher Plague. This takes us to the worst kind of user in the torrent community: the leecher. This is a user who configures his BitTorrent client to download only, and to avoid uploading. Or upload at a very slow rate. This means getting the file, but not giving it back , in order to save bandwidth. When the download is complete, they delete the torrent and don’t share it at all. This slows down the torrenting process for everyone. Supposably, a torrent is shared by seeders, but also by peers. That means different parts of the file are being shared simultaneously between everyone. That’s how P2P (Peer to Peer) works . That means that you take, and you immediately give to others who don’t have the parts you have. But because of the ones who only take and do not give, there are fewer sources to download from. More peers will have to share the available seeders. Obviously, if more people are downloading from the same source , the bandwidth will be divided by more users, meaning slower downloads. ISP Reducing Your Download Speed. Nowadays, an ISP throttling your torrent downloads is not that unusual. As you probably know, file-sharing is a delicate topic for many ISPs. When they realize you are torrenting, they may throttle your connection whenever you download a file . That means they slow down your connection, sometimes to incredibly low speeds. Even some ISPs that allow P2P will throttle you because these are downloads that involve a big amount of data and bandwidth. The bigger the file, the higher the costs on resources for them. By slowing you down, they are saving money . This situation happens even with the ISPs that say that you have unlimited bandwidth. That’s one of the reasons why users are opting to use a Virtual Private Network . That way, the ISP won’t know what they are doing. No one knows about any Internet activity, except for the user himself. A Word to VPN Users. For those who download torrents with a Virtual Private Network to remain anonymous, the reason for a slow download may be the VPN itself. Keep in mind that a VPN has many servers and some are slower than others . Make sure that you try different servers to see if it solves the issue. Remember that a VPN will always decrease your speed because of the resources it takes to encrypt your connection. Modern VPNs should have a small impact on speed, but the wrong choice of the VPN provider may slow you down significantly. But there are a few good choices out there. For example, NordVPN has dedicated P2P servers, which guarantees fast download speeds. Other Possible Reasons. Naturally, it may also happen that other external factors are interfering with your downloads, such as: Using bad trackers Wrong BitTorrent client configuration Interference with your Wi-Fi signal. Conclusion. The cause of torrent files not having any download progress is often related to the number of peers and seeders available. Make sure that checking those numbers in your torrent client is the first thing you do . Remember that seeders are always better, as they have the complete file already. But sometimes there are hidden obstacles that may be causing problems. That’s why it’s also good to verify your connection and tools that you’re using, such as your VPN. How to exclude files in torrent from download? Is it possible to exclude certain files within a torrent from downloading using the Transmission client? I can't seem to be able to find any such option. If I go to Properties → Files, there are no options whatsoever. I used to use this feature regularly in BitTorrent on Windows. 3 Answers 3. Yes, it is posible. Open transmision ->Click on the torrent you wish to edit -> Afther you click, you have on transmision top bar a button called Properties click on it. A new windows should appear On that windows you have a tab called Files click on it In this tab you should see some checkboxes, if you cannot see the ckeckboxes,resize the windows and make it bigger. Qbittorrent - Stalled (troubleshooting included) #1220. I have been using qbittorrent for a while and I hit the "Stalled" issue recently. After investigating on the forums and troubleshooting for a while, I hope I am able to shed some light on this. Backstory: I recently upgraded my broadband and getting trus 1 Gbps speed in the metropolitan area, and up to 500 Mbps outside the city limits, with speeds as high as 200 Mbps outside the country as well. Since then, utorrent (which I was using at the time) started to act weird. For example, after adding a few large torrents (usually over 10 GB in size) and starting to download, the client uses HDD continously and doesn't download. First I thought it's all about preallocating space, but it sits still even after 24h and after HDD stops churning. I moved to Qbittorrent and it was better, but a couple days ago I added some really large torrents (8 of them, around 80 GB each - it's a TV series that I already own in Bluray format but I want to stream it to my mobile devices using PLEX media Server). Qbittorrent started behaving exactly like uTorrent. Qbittorrent attempts to download; Download works for a few seconds (up to 30 seconds) at Ok speeds (even up to 20 MBps) Download speed goes gradually down to zero; HDD light is always ON; Qbittorrent shows all torrents as "Stalled"; Closing Qbittorrent leaves "qbittorrent.exe" process alive in processes list; trying to end process yields no results, I have to restart the OS to get it out of the way. If I don't restart and try to open Qbittorrent again, it starts and creates another process in the process list which actually can be killed. My guess is that Qbittorrent tries to preallocate files (although I told it not to) OR it has issues trying to download at high speeds and somehow craps out. I have gone as low as allowing only 2 torrents to download at the same time, which maked Qbittorrent set all but 2 torrents as "Queued" but the two remaining ones are. yes, you guessed right: "Stalled". Same behavior is visible for 3.1.2 and 3.1.4. Smaller torrents (e.g. DVD-sized) work fine. usually I am getting single-torrent download speed of 60-70 MBps, which probably is capped by HDD transfer capabilities.

In this guide, we will let you know how to bypass torrent block issue from any place or location. The task of downloading torrent files is one of the most interesting activities of torrent users throughout the world. There are hurdles like ISPs, copyright holders, governments and surveillance agencies that have spoiled the fun of the users in terms of browsing, surfing and downloading the internet. A VPN is the most effective way to bypass torrent blocking across the world. A VPN lets you access all torrent sites while keeping you anonymous by masking your IP address. With an encrypted tunnel created by a VPN, you are completely safe to bypass all torrent blocks easily.

  • A Study of Peer-To-Peer Systems
    A Study of Peer-to-Peer Systems JIA, Lu A Thesis Submitted in Partial Fulfilment of the Requirements for the Degree of Master of Philosophy in Information Engineering The Chinese University of Hong Kong August 2009 Abstract of thesis entitled: A Study of Peer-to-Peer Systems Submitted by JIA, Lu for the degree of Master of Philosophy at The Chinese University of Hong Kong in June 2009 Peer-to-peer (P2P) systems have evolved rapidly and become immensely popular in Internet. Users in P2P systems can share resources with each other and in this way the server loading is reduced. P2P systems' good performance and scalability attract a lot of interest in the research community as well as in industry. Yet, P2P systems are very complicated systems. Building a P2P system requires carefully and repeatedly thinking and ex- amining architectural design issues. Instead of setting foot in all aspects of designing a P2P system, this thesis focuses on two things: analyzing reliability and performance of different tracker designs and studying a large-scale P2P file sharing system, Xun- lei. The "tracker" of a P2P system is used to lookup which peers hold (or partially hold) a given object. There are various designs for the tracker function, from a single-server tracker, to DHT- based (distributed hash table) serverless systems. In the first part of this thesis, we classify the different tracker designs, dis- cuss the different considerations for these designs, and provide simple models to evaluate the reliability of these designs. Xunlei is a new proprietary P2P file sharing protocol that has become very popular in China.

A large number of mechanisms, policies, methods and schemes have been proposed for media coding, scheduling and distribution. Internet Protocol (IP) multicast was expected to be the primary transport mechanism for this, though it was never deployed to the expected extent. Recent developments in overlay networks has reactualized the research on multicast, with the consequence that many of the previous mechanisms and schemes are being re-evaluated. This report provides a brief overview of several important techniques for media broad- casting and stream merging, as well as a discussion of traditional IP multicast and overlay multicast. Additionally, we present a proposal for a new distribution system, based on the broadcast and stream merging algorithms in the BitTorrent distribution and repli- cation system. “replication-strategies” — 2007/4/24 — 10:56 — page ii — #4 ii “replication-strategies” — 2007/4/24 — 10:56 — page iii — #5 CONTENTS Contents 1 Introduction 1 1.1 Motivation .

An unfair P2P network may attract free-riders, frustrate the majority of users, and consequently shorten the longevity of files. When BitTorrent protocol was first introduced, by suggesting new algorithms like tit-for- tat or rarest-first and combining them with methods like choking and unchoking, it pushed fairness one step forward. However, BitTorrent did not bring a plenary solution and has its own shortcomings. For instance, neither this protocol nor other P2P protocols that we are aware of precisely indicate how seeders should be treated in their networks. Most of the time they dictate that seeders upload as much as possible. With this approach, seeders can easily be abused by free-riders. It gets even worse when we realize that for lack of a good infrastructure a lawful user may become a free-rider unknowingly. The purpose of this paper is to address this problem by suggesting a novel and universal method that can be implemented in current P2P networks.

  • Peer-To-Peer Networks – Protocols, Cooperation and Competition
    Peer-to-Peer Networks – Protocols, Cooperation and Competition Hyunggon Park Signal Processing Laboratory (LTS4), Institute of Electrical Engineering, Swiss Federal Institute of Technology (EPFL), Lausanne, Switzerland Rafit Izhak Ratzin Computer Science Department, University of California, Los Angeles (UCLA), Los Angeles, USA Mihaela van der Schaar Multimedia Communications and Systems Laboratory, Electrical Engineering Department, University of California, Los Angeles (UCLA), Los Angeles, USA 1. INTRODUCTION Peer-to-peer (P2P) networks connect many end-hosts (also referred to as peers) in an ad-hoc manner. P2P networks have been typically used for file sharing applications, which enable peers to share digitized content such as general documents, audio, video, electronic books, etc. Recently, more advanced applications such as real-time conferences, online gaming, and media streaming have also been deployed over such networks. Unlike traditional client-server networks, where servers only provide content, and clients only consume content, in P2P networks, each peer is both a client and a server. It has been observed that P2P file sharing applications dominate Internet traffic usage. In fact, a wide range of measurements, which were performed in 8 different geographic regions during the years of 2008-2009, show that P2P networks generated most of the traffic in all monitored regions, ranging from 43% in Northern Africa to 70% in Eastern Europe (http://www.ipoque.com/). The same study also identified that BitTorrent (Cohen, 2003) is the most popular protocol on the Internet, generating most of the traffic in 7 out of 8 regions ranging from 32% in South Africa to 57% in Eastern Europe. The details of the BitTorrent protocol will be discussed in Section 3.

William Pung, Andrew Woodward secau Security Research Centre, School of Computer and Security Science Edith Cowan University, Perth, Western Australia [email protected]; [email protected] Abstract BitTorrent is a peer to peer file sharing protocol used to exchange files over the internet, and is used for both legal and illegal activity. Newer BitTorrent client programs are using proprietary UDP based protocols as well as TCP to transmit traffic, and also have the option of encrypting the traffic. This network forensic research examined a number of packet analysis programs to determine whether they could detect such traffic from a packet captures of a complete file transmitted using one of four protocol options. The four states examined were: TCP without encryption, TCP with encryption, µTP without encryption and µTP with encryption, and the six programs investigated were: Network Miner, Tcpxtract, Honeysnap, OpenDPI, Netwitness Investigator and SPID.
