Hi,

I am new to KTorrent en BitTorrent. Now I am trying to use KTorrent trackerless. I configured 2 PC's on an internal network with KTorrent 2.0. I created a torrent on 1 PC, transfered the torrent to the other PC and tried to download the actual file. All downloads are waiting: "stalled". I stopped the firewall on both PC's so this can't be the problem.

When creating the torrent I used http://<internal ip>:6881 and tried http://<intrenal-ip>:4444 as tracker adress. DHT is switched on.

So most likely I do something stupid, but I don't know what and google doesn't give me a clue. Can anybody help me?

Thanks.

I'm not quite sure I understand what you want to do.

So, you have 2 networked PCs and you want to download torrents without a tracker, right? I'm not quite sure this will work automatically since there's a very small chance that IP of the computer seeding a torrent is saved in downloading client.
Anyway, placing DHT address (<internal-ip>:4444) for tracker address surely won't work. If there was a way to manually add a DHT node - something like this would work.

There's a pretty stupid workaround that comes to my mind: You can set up a tracker, create some torrent and and try seeding it. With downloading client try to download that torrent - tracker will return IP of a seeding client and it will be saved for future use with DHT. Then you could probably connect to that seeding client without a tracker...

Right

?? Trackerless torrents was one of the new features in Bittorrent 2.0 I thought?

In fact I can install a tracker myself , but somehow it should work without tracker I assume. But I can't find out how. Or does "trackerless" just mean that the download continues even if the tracker goes down after initiating the download? I am not sure about that.

KT supports trackerless torrents (DHT), you're right.
But your client somehow must collect nodes (peers IP) from somewhere. If you place two clients on internal network they'll never 'find' each other.

OK, I am an absolute beginner and stupid etc. But what does trackerless mean? If I need a tracker to work trackerless it seems to me there is something strange in the name trackerless.

A trackerless torrent contains a list of peers to get started. Currently KT does not support making these. Anyway you can just run a tracker on one off your networked PC's.

Download the mainline client there is a tracker in there.

However I don't understand why you want to do this locally between your 2 PC's. They are on the same network so you can use NFS, samba, FTP, TFTP, scp, netcat ... there are so many ways to do this.

Thanks for your explanation.

Well that is for testing purposes. So I can see what happens on both machines. When I find out how it works I will use it on the internet to swap personal files with family. I guess it is a good way to share family movies of the kids etc.
