I think you are trying to seed a *new* "unofficial" torrent. That's not what you want to do. See below. > > I presume this assumes I'm downloading originally.

Does the service CentOS is using support all this? It doesn't need to support this. The important thing is that *you* have to use a DHT client. utorrent uses this automatically (you can switch it on/off in the options, though). So, you have to look in the client documentation if and how it supports DHT (which seems to be the abbreviation for Distributed Hash Table). What you then simply do is fire up that client and get the CentOS torrent and keep it running once you got it. That's all. In case there's no tracker connectable DHT-aware clients will talk to each other and look for the hash. Which means if you already got it you can serve it. Or if you don't have it yet you can get it from others. Without a tracker. The important part is that all the DHT clients use the same torrent file for starting up the download. If you download the file by other means and then start seeding it (by creating your own torrent file and uploading it to a tracker) you start a new torrent "cloud" or whatever you want to call it. I'm sure there are ways to "trick" around this and use an existing torrent file with data that were downloaded a different way. Maybe just start a download, stop it and then replace the file with a complete one. Here's what's currently getting seeded: http://www.mininova.org/search/?search=Centos+5.1 The seed/leech ratio seems to be ok.
