Hello.

I am using KTorrent 3.2.0 i Fedora 10, KDE 4.2.2. The program seems to have trouble detecting online peers. When I enqueue a torrent for download, KTorrent will quickly procure a "total" number of seeders and leechers, but it tends to keep displaying "0/564 seeds, 0/897 leechers online".

Often, a torrent will stay at zero online peers (even out of a total of hundreds) for a day or several days before KTorrent finally starts finding some online peers. After that, it sometimes picks up and finds many peers quickly, but other times it keeps finding no more than one or two peers, or even stays at zero forever (out of a total of dozens or hundreds).

This applies both when I try to seed and download torrents.

I am positive that this is a KTorrent issue. Deluge, downloading the exact same torrent on the exact same machine, often finds many peers instantaneously, while KTorrent bumbles around for days at a time.

It might be a port forwarding issue. I have my router set to forward all the ports I use in KTorrent, and my firewall set to allow them through, but still this Open Port Check Tool tells me the ports in question are closed. However, from a thread I posted in the Fedora Forum, I have reason to believe that the "Open Port Check Tool" might not be entirely reliable.

Can anyone help with this?

Thanks in advance.

EDIT: To further test the port forwarding hypothesis, I I tried to make Deluge use the same ports that KTorrent uses. Deluge downloads fine. It must be a KTorrent problem.

Update: I cleaned up my system by removing all KTorrent-related files from my home directory and reinstalling KTorrent. That seems to have helped. I can download again.
