r11128 r11138 15 15 IETF RFC 2119 [#RFC-2119]_. 16 16 17 A *private tracker* restricts access to the torrents it tracks. A 18 torrent with restricted access is called a *private torrent*. To 19 promote sharing, private trackers often maintain statistics about 20 registered users and restrict access to certain or all torrents for 21 users that do not adequately upload. 17 A *private tracker* restricts access to the torrents it tracks. A 18 torrent with restricted access is called a *private torrent*. All 19 other torrents are *public torrents*. To promote sharing, private 20 trackers often maintain statistics about registered users and restrict 21 access to certain or all torrents for users that do not adequately 22 upload. 22 23 23 24 When generating a metainfo file, users denote a torrent as private by … … 29 30 private tracker, and MUST ONLY initiate connections to peers returned 30 31 from the private tracker. 32 33 When multiple trackers appear in the *announce-list* in the metainfo 34 file of a private torrent (see multitracker extension in [#BEP-12]_), 35 each peer MUST use only one tracker at a time and only switch between 36 trackers when the current tracker fails. When switching between 37 trackers, the peer MUST disconnect from all current peers and 38 reconnect only to those provided from the new tracker. 31 39 32 40 Rationale … … 59 67 with the intruder would provide the intruder with a full complement of 60 68 peers. 69 70 When a peer switches between trackers, the peer drops connections so 71 that it cannot become an ongoing bridge between peers granted access 72 from a private tracker and peers announcing to a public tracker. This 73 partially mitigates the effect of an attacker modifying a metainfo 74 file's *announce-list* and redistributing the file, e.g., via a public 75 tracker web site. 61 76 62 77
