Problems with Torrent-Download

[Potato]

Hello,

I'm trying to download images. What am I doing wrong? I tried commandline clients bittorrent and ctorrent.

bittorrent says:
These errors occurred during execution:
[10:32:40] Problem connecting to tracker - <urlopen error unknown url type: udp>

ctorrent says:
...
Listening on 0.0.0.0:2706
error, invalid tracker url format!
error, tracker setup failed.

Trying to download some Debian Images from Debian works. I'n not experienced in using torrent, so if you got some magic options for me.

See attached my complete console log for details.

Thanks a lot

We are using a number of public torrent trackers and also we seed all the time. If there are 0 peers listed at your side then the chances are that your network is blocking the torrent protocol. If you are trying to download it in a work environment then contact your network administrator and ask to download the torrent for you or, alternatively, try to download it at home. Make sure that the torrent protocol and ports are allowed by your ISP. If you have doubts, please, contact your ISP and explain the situation. If you are at home then try with another torrent client.

We used the have direct downloads before but the problem was that a lot of bot programs abused the direct downloads. This triggered hidden download limits and ultimately lead to greater unavailability of the files (remember that most of the images are very large). Most customers requested that we use a torrent system instead.

<BIG-EDIT> The problem is that your torrent client does not support UDP connections to the trackers (probably supports only HTTP). Our torrents use only UDP. The other torrent that you tried has HTTP for sure. Try with another torrent client and enable the UDP connection to the trackers. We would probably add some HTTP tracker links in future to avoid cases like this.

Best regards,

OK, I used qBittorrent from Debian Jessie and it worked! Jessies ctorrent and bittorrent did not!

Thanks a lot for your answer!

ctorrent seems to be broken. Try this way:

Code Select Expand

apt -y install aria2
wget https://dl.armbian.com/lime2/Debian_stretch_next.7z.torrent
aria2c Debian_stretch_next.7z.torrent
