Thread: ktorrent magnet link issue

  1. #1

    Default ktorrent magnet link issue

    ktorrent will work with this magnet link which is from kickasstorrents website:

    Code:
    magnet:?xt=urn:btih:BFEFB51F4670D682E98382ADF81014638A25105A&dn=opensuse+13+2+dvd+x86+64+iso&tr=udp%3A%2F%2Fopen.demonii.com%3A1337%2Fannounce
    It dosent work with this one though from theoldpiratebay:

    Code:
    magnet:?xt=urn:btih:bfefb51f4670d682e98382adf81014638a25105a&dn=openSUSE+13.2+DVD+x86_64.iso&xl=4678746112&dl=4678746112
    Strangely enough qBittorrent will work fine with both. When I say it dosent work I mean it takes a long time to find any peers, 5-10 minutes plus, it never really gets started tbh. Any ideas what causes this? What makes one of those magnet links different from the other? Any settings I can change in ktorrent to fix this?

    Can you please at least tell which version of openSUSE you use?
    And I assume you use KDE because you use ktorrent, but mentioning such information never hurts.

    Rather than downloading openSUSE ISOs from pirate websites, use the
    official torrent files on download.opensuse.org. Those torrent files are
    known to work, and are also known not to have been tampered with.

    Yeah I know but the point is every other torrent client ive tried (transmission/qbittorrent/utorrent) can use both magnet links, ktorrent has trouble with one of them. What gives?

    You didn't post the exact error you're seeing.
    More than likely there is a supported format issue, I doubt the problem is the magnet technology.

    One way to verify this is if as you say the torrent file can be downloaded with a different torrent client, open up the file in a text editor and compare it with some other torrent file which is no problem using either client.

    It may be that ktorrent might actually be the better performing client in this case, particularly if you're getting your torrent files from something like oldpiratebay.org which is only a demo of a very, very dead thepiratebay.

    is the re-encoding of the URI's, insted of / the link uses %2F, instead of : it uses %3A
    some webservers automatically encode URL's , ktorrent expects real addresses not encoded ones, if you fix the magnet URI (replace %3A with : etc) it would work

    I dont see an error, its just magnet links from that site dont start with ktorrent, as far as im aware theres no file to dissect with a magnet link? Torrents work fine with ktorrent.

    This magnet link:
    Code:
    magnet:?xt=urn:btih:BFEFB51F4670D682E98382ADF81014638A25105A&dn=opensuse+13+2+dvd+x86+64+iso&tr=udp%3A%2F%2Fopen.demonii.com%3A1337%2Fannounce

    Itll just sit there for ages before finding a single peer (it eventually finds a peer) I would be inclined to just blame the website but ive tried other magnet links and the same behavior happens, ktorrent effectively dosent work with them. qbittorrent on the other hand will work with all magnet links ive thrown at it, same with transmission. Both those links in particular work well with other torrent clients.

    You quoted the magnet link that works though, its the other one that dosent work.

    the torrent/magnet that doesn't work does not have any trackers,
    magnetxt=urn:btih:bfefb51f4670d682e98382adf81014638a25105a&dn=openSUSE+13.2+DVD+x86_64.iso&xl=4678746112&dl=4678746112
    the magnet only has the file hash no trackers!
    ktorrent sets dht to off by default, so eather edit the URI to include trackers or enable dht in ktorrent (it's in settings)

    a bugzilla report for this might be a good idea, I remember when I first started ktorrent with a tracker-less magnet I got no connections until I enabled DHT.
    ktorrent setting DHT should be ON by default.
