A BitTorrent tracker is server software that centrally coordinates the peer-to-peer (P2P) transfer of files among users. BitTorrents have a bad reputation because they have been used for piracy, but they aren't illegal. In fact, they have many legitimate and legal uses, including downloading open-source software and public domain files.

About BitTorrent Trackers

BitTorrent tracker software serves up torrent files for download from a website. The tracker maintains information about the BitTorrent clients using each torrent. Specifically, the tracker identifies the network location of each client that uploads or downloads the P2P file associated with a torrent. It also tracks which fragments of that file each client possesses to assist in efficient data-sharing among clients.

BitTorrent clients connect to a tracker when they log on to the server to work with torrent files. The tracker notifies the client of the P2P file location, which is on a different remote server. If the BitTorrent tracker fails or is taken offline, clients are unable to continue sharing P2P files. The tracker normally uses TCP port 6969 for network communications.

Several BitTorrent software programs are on the market. They include the following:

Vuze has been referred to as "ridiculously full-featured." This makes it a bit bulky and resource-heavy, but if you want all the bells and whistles, Vuze is a good choice.
