Apparently this is a typical "tracker" port, whereas 6881+ are typical client ports.

BitTorrent

XXX - add a brief BitTorrent description here

History

XXX - add a brief description of BitTorrent history

Protocol dependencies

  • ["TCP"]: Typically, BitTorrent uses ["TCP"] as its transport protocol. The well known TCP port for BitTorrent traffic is 6881-6889.

Example traffic

XXX - Add example traffic here (as plain text or Ethereal screenshot).

Ethereal

The BitTorrent dissector is (fully functional, partially functional, not existing, ... whatever the current state is).

Preference Settings

(XXX add links to preference settings affecting how PROTO is dissected).

Example capture file

XXX - Add a simple example capture file to the SampleCaptures page and link from here (see below). Keep this file short, it's also a good idea to gzip it to make it even smaller, as Ethereal can open gzipped files automatically.

  • attachment:SampleCaptures/PROTO.pcap

Display Filter

A complete list of BitTorrent display filter fields can be found in the [http://www.ethereal.com/docs/dfref/b/bittorrent.html display filter reference]

  • Show only the BitTorrent based traffic:

     bittorrent 

Note: implemented in Ethereal post 0.10.12!

Capture Filter

You cannot directly filter BitTorrent protocols while capturing. However, if you know the ["TCP"] port used (see above), you can filter on that one.

  • Capture only the BitTorrent tracker traffic over one of the default ports (6881):

     tcp port 6881 

XXX - how to filter the tcp port range 6881-6889?

Discussion

I've seen the usage of the TCP port 6969 while using BitTorrent. Is this the new web based tracker or simply a virus? - UlfLamping

Apparently this is a typical "tracker" port, whereas 6881+ are typical client ports.
