你可以把 tracker 改成 hash.bt.kenosisp2p.org，其中的 hash 改成檔案的 hash value 即可。

在 Unix 下用標準版本的 bittorrent 可以用 btreannounce.py 改，拿 Firefox 1.0.1 Bittorrent 下載例子來說，本來是這樣：

Firefox%20Setup%201.0.1.exe.torrent
info hash: 15bc86515fc1df90bc562f3fb8d4ab7efafbe5a4
announce url: http://bittorrent.mozilla.org:6969/announce
full copies: 33 seeds
partial copies: 6 leeches
Bytes File
4,816,320 Firefox Setup 1.0.1.exe

用 btreannounce.py 改：

gslin@netnews [~] [11:31/W3] btreannounce.py http://15bc86515fc1df90bc562f3fb8d4ab7efafbe5a4.bt.kenosisp2p.org:6969/announce Firefox%20Setup%201.0.1.exe.torrent
old announce for Firefox%20Setup%201.0.1.exe.torrent: http://bittorrent.mozilla.org:6969/announce

然後就變成這樣：

Firefox%20Setup%201.0.1.exe.torrent
info hash: 15bc86515fc1df90bc562f3fb8d4ab7efafbe5a4
announce url: http://15bc86515fc1df90bc562f3fb8d4ab7efafbe5a4.bt.kenosisp2p.org:6969/announce
