WLGades Posted March 2, 2006 Report Share Posted March 2, 2006 I did a search on various keywords like "seeding multiple torrents" and "multiple torrents same file" but didn't see anything related to this. I'm trying to switch all my torrenting needs over to use utorrent, but I can't seem to seed the same file on multiple torrents spanning multiple trackers. Ideally, every time I started a new torrent, if it was an existing one it would add it to the multiple trackers for that specific torrent (which I think utorrent already does), and would provide a breakdown of seeders/leechers for each tracker (which I don't think utorrent does). Barring that, I'd be fine with having the same file show up multiple times in utorrent, with the ability to close each of them whenever I wanted to.My use case is that I provide torrents to two or three different forums, and I usually hop off after there are a few seeds, but the time for that to happen will differ across torrents.Thanks for any help!

Firon Posted March 2, 2006 Report Share Posted March 2, 2006 It only shows the add tracker dialog when the torrent is -exactly- the same. If it does not show that, then the torrent is not identical. Link to comment Share on other sites More sharing options...
WLGades Posted March 2, 2006 Author Report Share Posted March 2, 2006 I assume that check is being done on the torrent hash, because I've tried adding the same file with the same hash but from two different forums (and two different trackers) and I still get the add tracker dialog. If there are different torrent hashes then I don't get that. Since I upload to forums with the exact same torrent usually (they overwrite the tracker on their end), the hash will be the same on all of them, but they'll be unique torrents. Any way around that?

splintax Posted March 2, 2006 Report Share Posted March 2, 2006 Not sure I quite understand what you're talking about.If the hash is the same (exact same file contents), then µT will ask you if it should add the trackers from the .torrent instead of starting a new download. Otherwise, it will open a new download.µT does not show individual peer data for each tracker. However, you can stop contributing to a given tracker by double-clicking the torrent and deleting the tracker URL in question. Link to comment Share on other sites More sharing options...
WLGades Posted March 2, 2006 Author Report Share Posted March 2, 2006 Sorry, when I was saying hash above, I meant the torrent_hash value, not the hash of the file. Each generated torrent has a hash value associated with it that's independent of the hash of the files in a torrent.The reason I need individual peer data per tracker is because I need to know when I've distributed at least a full copy so I can jump off, and that requires per-tracker stats.On a related note, how does utorrent choose which of multiple trackers to go to? If there are three trackers, will it try to grab peers from all 3, or does it only go to the second one if it can't find enough on the first?

DreadWingKnight Posted March 3, 2006 Report Share Posted March 3, 2006 On a related note, how does utorrent choose which of multiple trackers to go to? If there are three trackers, will it try to grab peers from all 3, or does it only go to the second one if it can't find enough on the first?It depends on the layout of the trackers. Some trackers are linked to behave as one (which uTorrent treats as one when properly entered in the .torrent) Others are not. Link to comment Share on other sites More sharing options...
WLGades Posted March 3, 2006 Author Report Share Posted March 3, 2006 So assuming I enter three separate trackers from three different torrents that all happen to have the same info_hash, what will happen? I assume that means it's treated as three individual trackers, but what's the formula/algorithm for determining where you get your peers? Link to comment Share on other sites More sharing options...
Firon Posted March 3, 2006 Report Share Posted March 3, 2006 If there's an empty line between the trackers, then it gets peers from all 3. if there's no empty line, then it treats them all as one tracker and won't announce to each one. Link to comment Share on other sites More sharing options...
WLGades Posted March 5, 2006 Author Report Share Posted March 5, 2006 Hm, but as you pointed out in another thread, it reports the aggregated download/upload to each tracker, which means you'll misreport your statistics to every one. I suppose there's no way around that? :-) Link to comment Share on other sites More sharing options...
Firon Posted March 5, 2006 Report Share Posted March 5, 2006 No. This happens in other clients too. There's no way to distinguish stats between each tracker. It's all or nothing. This is the same reason why it doesn't matter if you upload to peers obtained through the tracker, PEX, or DHT. Link to comment Share on other sites More sharing options...
WLGades Posted March 5, 2006 Author Report Share Posted March 5, 2006 Right, that makes sense. So I think the only solution is to change the torrent_hash value every time I upload the same torrent to multiple forums, and then utorrent will correctly see it. Should I make it a feature request? Although I'm not actually sure what would solve my problem--I suppose giving users the option of having multiple torrents with multiple trackers rather than combining multiple torrents into one torrent with multiple trackers...if that made any sense.

Firon Posted March 5, 2006 Report Share Posted March 5, 2006 Well, you don't want stats to be shared between the trackers. This can only be solved by having a different infohash (which means either an additional file, or different piece size), then loading both torrents into the client.
