Having problem seeding a completed file.

[waikontse]

Hi,

I'm trying to seed a file which has been downloaded successfully. The tracker registers that the client has the whole file, but when I try to download the file using another client, the client says the tracker has no seeders.

But when I switch the clients, the BT client does download from the seeder.

Any ideas?

Thanks

@waikontse , was there any problem with the library, or just some misunderstanding?

[waikontse]

I'm not really sure, but I think there is a problem with the library. I haven't done an extensive testing to pinpoint where things go wrong or just a misunderstanding of the library.

And as alternative torrent client, I'm using transmission 2.9.2.

But here are 3 scenarios that I've tested and the result of those.

Scenario 1

Seeder: transmission client
Leecher: bt client
Result: bt client downloads the file

Scenario 2

Seeder: bt client
Leecher: transmission client
Result: transmissions receives 0 peers from tracker and no downloading happens.

Scenario 3

Seeder: bt client
Leecher: bt client
Result: bt client downloads the file.

Any ideas where things might have gone wrong are helpful. And as bt client config, I just copy/paste the sample code on your front page.

Thank you for pointing out the different cases! I think I have an idea, will need to check.

Any updates?

I haven't work on the problem anymore, I've switched to another torrent library which I have to write a JNI wrapper for it.

@atomashpolskiy sorry is there any update?

[atomashpolskiy]

Unfortunately, it's not clear from the OP, what might cause this issue. In general case, seeding works.

I have the same issue too.
I don't know it's network issue or not(like UPnP or NAT). When I download content from a magnet link, it can upload some data... Arrrrr, around few MB for 3GB data.
But when I stopped download client and try to upload file, it cannot find any peers at all

The download and upload code is basically following you example of file sharing (Leecher.java, Seeder.java)

Right, torrent seeders don't look for leechers, it's the other way around. Seeders just "announce" to trackers and DHT, that they have something to upload. Or have I misunderstood you?

No, you're right.
The magnet link from the tracker has over 200 clients fetching the resources according to tracker records. It's nonsense that uploading keep 0 uploaded bytes for 2 hours.

[atomashpolskiy]

If it's a public torrent, then the majority of clients would be libtorrent/ztorrent/etc. based, and they might be biased with regards to less known clients (i.e. choose not to connect to such clients in presence of more preferable alternatives.) Just a wild guess, I honestly don't know. As I've said, seeding works (in Bt-only swarms usually, but I occasionally see the upload happening when downloading public torrents.) Reproducing and investigating problems in mixed swarms would require setting up infrastructure locally and looking at the things, and this is a significant effort, which I currently don't have the free time to undertake...
