cluck Posted June 7, 2007 Report Share Posted June 7, 2007 ive gotten 2300 hashfails on one torrent its been downloading the last percent for a week now. any ideas? Link to comment Share on other sites More sharing options...
Honeyfrog Posted June 7, 2007 Report Share Posted June 7, 2007 Whomever is seeding it has corrupted their own data and doesn't know it. They need to halt and force re-check. Link to comment Share on other sites More sharing options...
Firon Posted June 7, 2007 Report Share Posted June 7, 2007 Either that, or it's a poisoned torrent. Link to comment Share on other sites More sharing options...
Ultima Posted June 7, 2007 Report Share Posted June 7, 2007 More likely a poisoned torrent than anything. I can't imagine unintentional sharing of corrupt pieces causing thousands of hashfails. Link to comment Share on other sites More sharing options...
cluck Posted June 7, 2007 Author Report Share Posted June 7, 2007 what about turning off hashchecking just to finish the download, what might be the potential consequences? Link to comment Share on other sites More sharing options...
DreadWingKnight Posted June 7, 2007 Report Share Posted June 7, 2007 100% guaranteed corrupted download.http://utorrent.com/faq.php#I_get_tons_of_hashfails_on_my_torrents_and_the_torrent_never_finishes Link to comment Share on other sites More sharing options...
Switeck Posted June 7, 2007 Report Share Posted June 7, 2007 You probably will need to block the hostile ips with ipfilter.dat -- look for tight groupings of ips. Link to comment Share on other sites More sharing options...
cluck Posted June 8, 2007 Author Report Share Posted June 8, 2007 but doesn't utorrent block them automatically after like 5 hashfails? ive downloaded the same pieces over a hundred times each. its just a 93 meger so it doesnt take long but since so many ips are blocked i down get many connected peers.

Ultima Posted June 8, 2007 Report Share Posted June 8, 2007 Lots of poisoners. µTorrent 1.7 blocks entire ranges if needed (and the relevant option is enabled -- bt.use_blockrange), but 1.6.1 and older only ban IP by IP. Link to comment Share on other sites More sharing options...
Honeyfrog Posted June 8, 2007 Report Share Posted June 8, 2007 How long does an IP or range stayed blocked? In the past I've noticed the same guy would appear again, after a long while or a restart, after being auto-punted. Link to comment Share on other sites More sharing options...
Switeck Posted June 8, 2007 Report Share Posted June 8, 2007 You just HAVE to add the hostile ranges to your ipfilter.dat if you want any chances of downloading a poisoned torrent. And even then your odds won't be great. Link to comment Share on other sites More sharing options...
Ultima Posted June 8, 2007 Report Share Posted June 8, 2007 @Honeyfrog: Permanent unless the bans are manually cleared. Link to comment Share on other sites More sharing options...
Honeyfrog Posted June 8, 2007 Report Share Posted June 8, 2007 You may want to put a duration limit (3mo?) on auto-blocklist entries. Peers sometimes inadvertantly send bad data due to hard-drive corruption from a crash, and a bad peer may close his account with his ISP, which then provides the IP to another customer. Pro fakebots are likely to change their IPs regularly anyway. Link to comment Share on other sites More sharing options...
µtorrent-Guest Posted June 8, 2007 Report Share Posted June 8, 2007 Honeyfrog, you misread Ultima I guess. The auto ban of hashfailers stays just for the active session of µt. (if you don't close and restart µT in 3 month by chance ... ;-) )If you enter the IP's in the ipfilter.dat blocklist file they stay there and are active as long as you use the list with its entries.So by pointing out that "Pro fakebots are likely to change their IPs regularly anyway" you were so nice to also point out why publicly downloadable blocklists are in effect useless to protect you from being "catched" by copyrightenforcers. thanks for that :-) Link to comment Share on other sites More sharing options...
Switeck Posted June 8, 2007 Report Share Posted June 8, 2007 However there ARE certain commercial ip ranges that are CONSISTANTLY and permanently hostile.I personally don't trust anything in the 38.x.x.x block without first checking it with a WHOIS scan.

Honeyfrog Posted June 11, 2007 Report Share Posted June 11, 2007 The auto ban of hashfailers stays just for the active session of µt.I'd to see that increased to a set number of days. I frequently have to shut down uTorrent (let alone my computer) for all kinds of reasons.by pointing out that "Pro fakebots are likely to change their IPs regularly anyway" you were so nice to also point out why publicly downloadable blocklists are in effect useless to protect you from being "catched" by copyrightenforcers. thanks for that :-)Condoms, body-armor and immunization shots for children don't stop everything either. Nothing is perfect: Bad guys and diseases evolve; the best you can hope to do is keep pace and deflect their attentions toward completely unprotected prey.PG is, IMO, an indespensible tool for the sole reason of being able to create my own personal blocklists for particularly odious leeches, and also for the ability to determine whether or not pingstorming fakebots are riding along certain announce URLs in a multi-tracker .torrent (which, when hacked out followed by a restart, may help boost speeds enormously, particularly if the pingstorming had prompted one's ISP to throttle bandwidth).
