Hello,
I don't know if it is a bug but I presume it is a bug.
I use an onlineservice named onlinetvrecorder (http://www.onlinetvrecorder.com/). There you can let a server record german telecasts and download it. You can download the file by three ways: paid-download, download form external servers(free) and torrent. So I wanted to use the torrent and add some externel servers as webseeds. Most times there are between 0 and 5 seeders and 2 .. 10 leechers. And there is the problem.
After some MiB (for example 10 MiB) the webseed changes to status "not used" and never reactivate. I tried it with other otr-torrents, other servers, one webseed, more webseeds, with running other torrents, without other torrent, with deactivated tracker and removed seeders and leechers. It is every time the same and I don't understand why. If I remove the webseed and readd the same webseed or restart ktorrent, ktorrent use the webseed for some MiB and then changes to "not used" again.

Version 3.3.2; KDE 4.3.4 "release 2"
And Version 3.2.4; KDE 4.3.2 (same Problem)

I will register at that site, and see if I can reproduce it.

OK. Thank you very much.

I wasn't inactive and reproduced the problem with the Knoppix-Torrent (knoppix is known?). So I downloaded the Knoppix-Torrent, deactivate all other torrents and added the knoppixtorrent as "not started". I deactivated the tracker, dht and interact with other clients and started the torrent. Perfect no seeders, no leechers, no download. Time to add a webseed. The webseed reconnects a little bit often in my opinion but it works. After 21 MiB I restarted an other torrent and the webseed changes immediately to not used and the other torrent downloads with 7 KiB/s and uploads with 16 KiB/s. I redeactivate the other torrent, the webseed is not used. I wait and write this text and I have got 0 upload and 0 download for the last 20 minutes.

It seems KTorrent only uses webseeds as a last resort (i.e. if there are no other peers it can download from), if there is some downloading going on the webseed changes to "not used". This is terrible if the only peer one can load from only offers a low bandwidth.

So it would be nice to have a threshold and have it configurable or an ability to manually say "I want to actually use that webseed" (probably from the context menu which is empty anyway). If the load put on the server concerns you one could limit the bandwidth for the webseed.

Good evening!

Well it's again that time of the year (easter or xmas), where television companies overwhelm my vcr. So this time I accepted the help of OTR. Now, that most of the recording is done, I have to download all those movies. At first I opted for torrents, but while I'm still waiting for the first torrent I started this morning, I finished a plain http download within half an hour for the same file.

I tried to provide the http url into ktrorrent, but the webseed is just defunct and switches to "30 seconds stalled (to many connection errors)".

1. I'd like to monitor more closely what's wrong with the server? Double clicking or right clicking the webseed has no effect. Other options? Log files?
2. How to check the URL, if it's suitable for random access? Typical One-Click-Hosters are really fragile to connect to. Usually the URL is only valid for a single connection. So even stopping and resuming immediately thereafter will fail the download. At first I tried to copy the URL from the download in Firefox, while it was already running. But as this didn't work, I went through the timeouts again to obtain a fresh URL and extracted it by right click to paste it to KTorrent.
3. As this also didn't work as a webseed, I gave up about 5 minutes later and pasted the same URL back to FireFox. It was perfectly operative and resulted in a secondary copy of the file within half an hour. Is there a way to fill in the gaps of the still slowly running torrent to effectively seed the missing parts for others? Can I somehow point KTorrent to the complete file and add that as a secondary source (including all the checksum-hashing)
4. Finally there is a broken partial file from my first attempt with the oneclick-hoster. It's only several mega-byte large. But sometimes I loose a download right before the end. This is especially annoying, as one-click-hoster often cannot resume. Is there a way to incorporate such unfinished pieces into an ongoing torrent download?

PS: Version KTorrent 4.1.1 in KDE 4.7.4 Kubuntu 11.10

Just a little update for the record:

The file that came from the webserver was not compatible with the same-titled file loading via the torrent. They had different checksums. It would have been good, if KTorrent would have told me about this incompatibility. Thats what checksums are for in the end.

On the other hand you could argue with OTR why they encrypt the same file multiple times just to track their users. But that does not belong here.
