mikhailmv Posted July 25, 2007 Report Share Posted July 25, 2007 I have: router - Linksys WRT54G ver 8 firmware 8.00.2 modem - Motorola SB5100 OS - Windows 2003 R2 SP2 client - uTorrent 1.7.1 (updated to 1.7.2 just now). All ports are forwarded properly. DHT is off. Global number of connections is 600. Maximum number of connected peers per torrent is 100. Number of upload slots per torrent is 8. Download is unlimited. Upload is limited to 100KB/s.I have had no problems with downloading different torrents from different trackers what-so-ever until I encountered this one:http://thepiratebay.org/tor/3462869/Babylon_5__all_5_seasons__the_full_length_movies_and_the_spinoffEverything was ok for a while, until it reached about 14%. (The speed was not that great: 25-75 kB/s). Than it just knocked out the router. I reseted the router. The router got knocked out again. I changed the router for the NR041. At this moment I noticed that I just can not use Internet while this particular torrent is in downloading state. It just saturates the whole bandwidth. (I have cablevision boost 30Mb/s on 5Mb/s). Even without a router at all it is impossible to use Internet.I checked the performance counters: TCPIPv4 Connection Failures, Connections Established and Connections Reset.It showed a steady increase in Connection Failures (like 1-2 per second) (that looks like normal) and for Connection Established it was around 104.(Now with this torrent being stopped and downloading several others it is around 150 and everything else works fine).P.S. I'm not sure if this is the right forum for this topic or it should be in Speed Problems. If it is so please move it there. Thank you. Link to comment Share on other sites More sharing options...
Firon Posted July 26, 2007 Report Share Posted July 26, 2007 What is net.max_halfopen set to? Link to comment Share on other sites More sharing options...
Switeck Posted July 26, 2007 Report Share Posted July 26, 2007 Did you block the hostiles on that torrent using µTorrent's ipfilter.dat file? Link to comment Share on other sites More sharing options...
mikhailmv Posted July 26, 2007 Author Report Share Posted July 26, 2007 net.max_halfopen is set to 8. The tcpip.sys is patched.If it is possible a little bit more detailed about ipfilter.dat or a link please.ipfilter.dat just blocks a range of ip addresses. So what do you mean by hostile for a particular torrent? Link to comment Share on other sites More sharing options...
Switeck Posted July 26, 2007 Report Share Posted July 26, 2007 There are likely hostile "peers" and "seeds" on that torrent that aren't what they claim they are...they're only there to try to foul up your download AND upload...and if given a chance, your whole internet connection. Typically, many of them fall into narrow ip ranges, such as 38.100.x.x or narrower. So look for many peers/seeds with close ip ranges (sort by range to make this easier).Do you have DHT, UPnP, or Resolve IPs enabled?(Any of these can overload marginal networking hardware and software.)

mikhailmv Posted July 26, 2007 Author Report Share Posted July 26, 2007 I downloaded the ipfilter.dat dated 07.07.2007 load it through the peers tab. The result is the same.DHT, UPnP are off.Resolve IPs is enabled. Link to comment Share on other sites More sharing options...
