Torrent cast without tracker server


  • Hi,

    I have seen that BitTorrent is not working currently. I might have an easy way to make it work.

    BitTorrent has a not very well known feature : local peer discovery. With local peer discovery and webseeding, you don’t even need a tracker server.

    Here is how I use it to distribute large files on my network.

    I have a web server which host the file (big.iso here) and a metalink file like this :

    <?xml version="1.0" encoding="UTF-8"?>
     <metalink version="3.0" xmlns="http://www.metalinker.org/">
       <files>
         <file name="big.iso">
           <resources>
             <url type="http">http://file-server/big.iso</url>
             <url type="bittorrent">http://file-server/big.iso.torrent</url>
           </resources>
         </file>
       </files>
     </metalink>
    

    on the clients I run

    aria2c.exe --bt-enable-lpd=true --enable-dht=false --bt-exclude-tracker='*' --seed-time=0  http://file-server/big.iso.metalink
    

    I create the torrent file and metalink file with a these bash functions :

    function mk_torrent {
       print_info "Creating torrent file for $1"
       transmission-create "$1"
       chmod a+r "$1.torrent"
    }
    
    function mk_metalink {
       file_url="$REPO/$1"
       torrent_url="$REPO/$1.torrent"
    
       print_info "Checking URLs"
       wget --spider "$file_url" "$torrent_url" || \
           ( print_error "Can't access file(s) via HTTP." && exit 1 )
    
       print_info "Creating metalink file for $1"
       cat > "$1.metalink" <<EOL
    <?xml version="1.0" encoding="UTF-8"?>
    <metalink version="3.0" xmlns="http://www.metalinker.org/">
      <files>
        <file name="$1">
          <resources>
            <url type="http">$REPO/$1</url>
            <url type="bittorrent">$REPO/$1.torrent</url>
          </resources>
        </file>
      </files>
    </metalink>
    EOL
    }
    

    I’m not a FOG user (yet) and I don’t know how easy it would be to implement this. I hope it helps anyway.
