peer_id

[pinolallo]

Hello,

I'm running an important bittorent italian tracker/community,

My tracker use the client id (not the http client declare) in order to match the bittorent client/version.

This works fine and using this way I can detect the 97% of all peers.

I have used the specs from http://wiki.theory.org/BitTorrentSpecification

Actually is usual use this kind of peerId Schema on the first 7 byte of peerid:

'-AZ2060-'

that is an underscore, a twoByte ascii Client identifiel and a four byte ascii version number. The example identify (-)(AZ)(2060)(-) Azureus v.2.0.6.0.

This coding way is adopted now also from BitComet.

As you can read from the above posted page link, there are also different coding way for the peerid: the question is uTorrent wich peerid schema use?.

Thanks for the answer.

µTorrent uses the azureus style coding, using the letters UT.

Thus the peerid looks like: -UT1160-
