  1. BTSync blocked in China?

    in Sync General Discussion

    Posted

    @RomanZ  the following is my nslookup result:

     

    Non-authoritative answer:

    Name:    config.usyncapp.com

    Addresses:  54.225.196.38

              54.225.100.8

              54.225.92.50

     

    This result appears to be correct, however, 1.3.109 still does not work on my windows 7. 

     

    BTW, I can use IE to download the file from  http://config.usyncapp.com/sync.conf on my disk(This indicates that this link is not blocked by GFW.)；In addition, I did icmp ping and tcp ping test for config.usyncapp.com, the result is ok. 

     

    I really do not understand where is blocked, leading to not communicate in 1.3.109.

  2. BTSync blocked in China?

    @RomanZ All versions do not work after 1.2.92 in China. Currently 1.2.92 version + the correct hosts file are worked and fine in China. Use the same way to 1.3 and 1.4, do not work. Pls help... Thanks


    @RomanZ I do not know what happened? Is the new version(1.3 or 1.4) uses new ip address or hostname outside 1.2.92?

    prosciutboy,

     

    Glad to hear you've found a workaround and now it works for you!

    Currently, I have encountered the same problem with you, do I also need to install DNSCrypt in my windows server? 

    BTW, I am wondering how to do by GFW, it actually can be a priority of my local hosts file, and misled me into 59.24.3.173

    Hi RomanZ, your advice is good but I don't really know to check how the DNS resolver works... and I wonder if there is any easy way to modify the way it works. 

     

    Anyway, I manage to bypass this issue and I can now sync with peers outside my network !

    As already stated, the problem is due to the DNS Poisoning performed by the Chinese Great Firewall (the famously terrible GFW). To prevent this alteration, I compiled and configured DNSCrypt on my RPi and the IP of t.usyncapp.com is now resolved perfectly.

     

    That might be useful for others so I will write a tutorial in the next days.

     

    Thanks again to dms2013 and RomanZ for their help.

    cz2000,

     

    In the past I've realized, that only DNS is incorrectly resolved in China, while actual connection is possible. Please try to associate next IP addresses with config.usyncapp.com in your hosts file: 54.225.92.50, 54.225.196.38, 54.225.100.8

     

    fbreve,

    Thanks for reporting. We'll try to reproduce this issue in our lab.

     

    d9nut,

    Thanks for reporting! Any chance to get debug logs?

     

    capi,

    Thanks for getting crash log. We'll take a look at at and get back to you.

    Hello, RomanZ

    China DNS indeed done the dirty action, which I have gotten in the last r.usyncapp.com too, so I've previously resolved the three correct address(54.225.92.50, 54.225.196.38, 54.225.100.8) for config.usyncapp.com, and write into my hosts file, however, the fault persists, and display same error.  I suspect this period of ip address (54.225.92.50, 54.225.196.38, 54.225.100.8) has blocked by China GFW. 

     

    BTW, are you still able to make r.usyncapp.com work in 1.3.XX?

    Hello, Admin

     

    Chinese users can not access config.usyncapp.com, keep trying, that is not found in any other machine. Version 1.2.92 uses r.usyncapp.com, do not have this problem
