rtorrent failing to download one particular torrent

postcd · 12-09-2013, 04:43 AM

Hello,

my "rtorrent" under linux CentOS (RHEL) works and download torrents, but one particular torrent not. It checks thru trackers, but dont download anything, please can anyone help on how to debug what is the issue?

The total size of files in torrent is 200GB, i have VPS which i can resize up to this size when needed. This is one cause that comes to my mind.

Another is that most trackers shows: Focus: no Enabled: yes Open: no

Could check (don't know the value though: see the documentation) if rtorrent tries to pre-allocate files and turn that off?

Also check if DHT is on: 'grep ^dht ~/.rtorrent.rc' and if it isn't enable it. I also check torrents for DHT and add a dht:// line if there isn't any.

Also check its log lines for any clues. If you need more nfo you can try adding "handshake_log=yes" to your config.

thanks, but its not solved. i added "system.file.allocate.set = no" and also i red its by default this way. But this did not fixed issue.

Then I did: grep ^dht ~/.rtorrent.rc
and it did not returned anything, so i tried to add line:

dht = auto
and after that
dht = on

but when it was there, torrent did not started automatically, but shown as [closed], after starting, when connecting to trackers, it says:
Unable to connect to UDP tracker

But the first message before first tracker: unable to connect hostname

Please any idea?

ps: handshake_log is inproper variable, rtorrent fails to start

"l" command shows empty log.

Check if your firewall isn't blocking anything, try to resolve the trackers host name, see if you can (tcp?)traceroute to it else disable the first tracker and trigger a request ("t" or capital "T"). Watch output, rinse, repeat. If you don't have any trackers left (I notice you didn't add a dht:// line) then add some regular trackers and see if that works.
