BitTorrent client

From Wikipedia, the free encyclopedia

This article is about BitTorrent clients in general. For the client created by Bram Cohen, see BitTorrent (software).

A BitTorrent client is a program that manages torrent downloads and uploads using the BitTorrent protocol.

The first client, known as BitTorrent, was created by Bram Cohen in the summer of 2002. Many other subsequent clients are based on in the first BitTorrent client in some parts. There are clients which are based on their coding base though. In addition, not all clients were built originally for BitTorrent, with some having the BitTorrent protocol support added later in. Since there are a large amount of BitTorrent Clients, there have been attempts to package malware as clients.

[edit] Notes

  1. ^ a b Clients that have been seen in the real world to actually work with IPv6, see IPv6 BitTorrent Clients
  2. ^ a b c Announcements to the tracker are made via IPv6 if possible, but the client doesn't listen on the respective port.
  3. ^ a b Linux version works, Windows version has not been working with IPv6 due to Java Bug 6230761
  4. ^ The official BitComet website claims that "BitComet does not contain any adware or spyware". However, versions 0.85 to 0.97 contained advertising. The current versions no longer contain advertising, except in the web-based search window.
  5. ^ Through wwwBTG, a web front-end
  6. ^ Available via MacPorts
  7. ^ Claims to be open-source but is based on a binary-only component (Red Swoosh), which is installed automatically.
  8. ^ a b c d e f g h i j When Azureus module is used
  9. ^ Unofficial version of Rufus created by TorrentSpy with WhenU SaveNow adware bundled in it; reportedly possible to opt-out during installation.
  10. ^ a b c The official FAQ and manual claim that µTorrent works under Linux, BSD, and Mac OS X using Wine 0.9.16+ with only minor interface issues.
  11. ^ a b Automatically configure port forwarding (requires Router with UPnP support)
  12. ^ a b DHT permits use of trackerless torrents (with supporting clients) to resume normal torrents when their tracker is down. However, some trackers that register their users for keeping tabs on fair usage (such as a ratio of bytes downloaded to uploaded) may not reliably measure and update usage for users employing DHT.
  13. ^ Since version 2.5.0.2. It's UDP based, an experimental feature and only supported by other Azureus clients
  14. ^ a b Has its own DHT, a mainline-DHT compatible implementation is available as plugin
  15. ^ a b c Tracker included with Linux binaries and with source, but not with Windows binary
  16. ^ Exchanging with BT 6 and µTorrent clients (and now MooPolice)
  17. ^ It's UDP based, an experimental feature and only supported by other Azureus based clients
  18. ^ Localhost uses a DHT protocol called Kademlia to connect to peers that are running Localhost. Each peer has an index of directories and files that it shares with peers that it is connected to. No one peer is responsible for storing the entire directory structure, it is distributed among everyone. It is collaboratively maintained, edited and built upon by all users in a popularity based system.
  19. ^ Exchanging with µTorrent
  20. ^ Weekly - Desktop Team - by Opera Desktop Team
  21. ^ Opera 9.5 Beta 1 for Windows Changelog
  22. ^ It's not a DHT network, but Shareaza uses gnutella2 to find other Shareaza clients.
  23. ^ Exchanges with µTorrent and Azureus peers.
  24. ^ µTorrent's [1] DHT implementation is the same as Mainline and BitComet's, but unfortunately this is incompatible with Azureus's implementation.
  25. ^ Exchanging with BT 6 and µTorrent clients (and now MooPolice)
  26. ^ Exchanges with µTorrent and Azureus peers.
  27. ^ a b Reduces disk usage, file fragmentation (in case it is not preallocated) and latencies due to larger written blocks and cached data for hash checking finished pieces.
  28. ^ a b Recently implemented (unofficial) web seeding feature, see HTTP-Based Seeding Specification
  29. ^ a b Supports the Getright Webseeding spec in addition to the Bittornado spec[2]
  30. ^ a b c Provides a Java-based and a simple Web-based user interface.
  31. ^ See task #4401 Socks Proxy; however, http proxy is supported.
  32. ^ Integrated
  33. ^ 3rd party utility RSSDler
  34. ^ Max active torrents number depends of configured connection speed
