baliator Posted January 10, 2008 Report Share Posted January 10, 2008 Hi, I'm kind of new in torrent. I mean I've downloaded a lot but never experienced this kind of behavior.I'm downloading big file (2.66 GB), 1.1 is already downloaded but 615 MB from it is wasted (hashfails). Isn't it too much? Is something wrong with the file I'm downloading? Or is this normal when downloading bigger files?Cheers Link to comment Share on other sites More sharing options...
Lord Alderaan Posted January 10, 2008 Report Share Posted January 10, 2008 Probably poisoned torrent or buggy router. Link to comment Share on other sites More sharing options...
baliator Posted January 10, 2008 Author Report Share Posted January 10, 2008 So, what should I do?This is a torrent I'm downloading: http://www.slotorrent.net/tor_aa2ba4ffe17b8d92be1014f5a6cfa55aa02c7eb4.htmlbtw: I'm not using router, I have a direct cable connection.Thx Link to comment Share on other sites More sharing options...
Switeck Posted January 10, 2008 Report Share Posted January 10, 2008 You could block hostile ips using ipfilter.dat...Probably best to block ip ranges that are likely to cover their whole possible values, such as:38.90.0.0-38.120.255.255 Link to comment Share on other sites More sharing options...
baliator Posted January 10, 2008 Author Report Share Posted January 10, 2008 little help pls.in FAQ they say: Place it in %AppData%\uTorrent, and set ipfilter.enable to true in the Advanced.I can't find that folder. Does it exist or should I create the folder in Users/MyPc/AppData by myself and then create the file.Cheers Link to comment Share on other sites More sharing options...

baliator Posted January 11, 2008 Author Report Share Posted January 11, 2008 Ok I applied ipfilter,, but I had another 600 MB of waste overnight. Should I discontinue download, or will it eventually download (I'm on 50% now and I don't want just throw it away )?Recommendations?THX Link to comment Share on other sites More sharing options...
jewelisheaven Posted January 11, 2008 Report Share Posted January 11, 2008 If you continue to see valid peers on the swarm, which keep the availability > 1.000 you will complete it. It's always your choice as the user whether or not to continue downloading from within poisoned/interdicted swarms. Link to comment Share on other sites More sharing options...
ciper Posted January 11, 2008 Report Share Posted January 11, 2008 I am trying the same file as he was and can confirm that it has a fairly large amount of hash fails. So far 349mb downloaded with 72.6mb of hash fails. Link to comment Share on other sites More sharing options...
Lord Alderaan Posted January 11, 2008 Report Share Posted January 11, 2008 The torrent is poisoned. That means that there are peers sending bad data on purpose.You can filter out the bad apples by banning whole ranges (using ipfilter.dat) instead of letting µtorrent ban them one by one. But keep in mind there is a chance the torrent is poisoned beyond repair or might have been an faked torrent in the first place. Link to comment Share on other sites More sharing options...
baliator Posted January 11, 2008 Author Report Share Posted January 11, 2008 Oki and how do I know which ranges to block? I've already blocked 38.90.0.0-38.120.255.255 as Switeck recommended. Link to comment Share on other sites More sharing options...
Lord Alderaan Posted January 11, 2008 Report Share Posted January 11, 2008 You look at the IPs that utorrent bans and you try to determine if they are in a single or a few ranges and ban those ranges.Unban them afterwards. Link to comment Share on other sites More sharing options...
Switeck Posted January 11, 2008 Report Share Posted January 11, 2008 Did the range I suggest actually block anything on that torrent? Link to comment Share on other sites More sharing options...
baliator Posted January 12, 2008 Author Report Share Posted January 12, 2008 to Lord Alderaan: Is there any log with banned IPs? In tab Logger there is nothing after program restart. It just says: loaded ipfilter.dat. Doesn't it mean that previously banned IPs aren't banned anymore?to Switeck: How do I find out? If I look into tab peers there is no IP with this range, so I Supose that ipfilter is working. Link to comment Share on other sites More sharing options...
jewelisheaven Posted January 12, 2008 Report Share Posted January 12, 2008 With Verbose logging on (in 1.7, customized blocked connections on 1.8) you will see "rangeblock" or "blocked IP" messages. That's how you'll know Link to comment Share on other sites More sharing options...
Switeck Posted January 12, 2008 Report Share Posted January 12, 2008 baliator,If you're still having big hashfails, try looking at the peers list for any ips that fail 1 hash check each.See if there's any close to each other in ip number. Link to comment Share on other sites More sharing options...
baliator Posted January 13, 2008 Author Report Share Posted January 13, 2008 ok,from Logger I found out that uTorrent is mostly banning IPs starting with 208.10 so I blocked whole range 208.10.0.0-208.255.255.255/Now my Logger says every minute: ipfilter blocked peer 208.102.139.253.Why is it saying once a minute? I thought when once it is blocked it won't try to connect again.I'll see tomoz if it solved that hash problem. Link to comment Share on other sites More sharing options...
jewelisheaven Posted January 13, 2008 Report Share Posted January 13, 2008 Until you get 1.8 you will see that every time any blocked peer connects to you (you see why many .. ok ok, I pushed.. for customizable logging options). It blocks the attempt from then on, but uT still tells you about it because it wants you to know how "bad" that swarm is in relation to your ipfilter.dat Definitely removing bad peers from the swarm will reduce the % overhead to get more of the file downloaded.

Switeck Posted January 13, 2008 Report Share Posted January 13, 2008 Your uTorrent is not trying to connect to them once you've blocked the 'bad' ips.Instead they're trying to connect to you.It's the difference of who is trying to make the phonecall and who is the receiver.Your ip range is quite likely overkill. The 208.10. ips you mentioned maps to Cogent, the same massive company that supplies business lines and backbone to many smaller companies. The entire 38.0.0.0-38.255.255.255 block belongs to them.I found these 2 ranges associated with Cogent:208.10.23.0/24208.10.29.0/24Note: Different ip range format than uTorrent uses! The /24 means only the last number changes -- it's a bitmask that maps out from 208.10.23.0 to 208.10.23.255A smaller number like /8 on 38.0.0.0/8 maps out 38.0.0.0-38.255.255.255But 208.10.0.0-208.10.255.255 is a much smaller range than you're using and should still get the Cogent ones you're seeing.Look for more! These hash poisoners seldom work out of just 1 small ip range anymore!More "nearby" Cogent ip ranges that are used probably by some other companies:208.13.70.0/24208.44.234.0/24208.67.240.0/22208.75.10.0/24208.75.96.0/21208.77.232.0/21208.80.16.0/21And then there's other nearby ips that are probably not associated with the hash-failing poisoners...208.102.139.253 for instance mapped out to:OrgName: Fuse Internet AccessOrgID: FIAIAddress: 209 W. Seventh St.City: CincinnatiStateProv: OHPostalCode: 45202Country: USNetRange: 208.102.0.0 - 208.102.255.255(I'm using http://www.dslreports.com/whois ) Link to comment Share on other sites More sharing options...
