EricRF Posted June 21, 2014 Report Share Posted June 21, 2014 Hello... Using Little Snitch on the Mac, I'm finding BitTorrent Sync is trying to connect regularly to unknown/unfamiliar IP addresses. Why would this be? Here are some of the IP addresses: port 43611 of 162.253.128.167port 43611 of 184.75.214.58port 43611 of 216.15.114.189port 43611 of 162.253.130.114 All are UDP ports. Is this something to be concerned about? Can anybody help? Thanks! -Eric Quote Link to post Share on other sites
GreatMarko Posted June 21, 2014 Report Share Posted June 21, 2014 Turn off "Search DHT Network" (this is a per-folder setting) Quote Link to post Share on other sites
EricRF Posted June 22, 2014 Author Report Share Posted June 22, 2014 Turn off "Search DHT Network" (this is a per-folder setting) Thanks for the suggestion, Marko, but it wasn't on to begin with Quote Link to post Share on other sites
RomanZ Posted June 22, 2014 Report Share Posted June 22, 2014 @EricRF When you see BTSync talking to some unknown IP addresses indicates that it communicates DHT network. Also, if you turn it on once for even a while - DHT network will remember your IP:port and still send some packets to you. I suggest checking that DHT is off for all folders and changing listening port so DHT can't contact your peer anymore. Quote Link to post Share on other sites

Thanks @RomanZ... but I don't have DHT on for any folders, and don't believe I ever did, since I don't even know what DHT stands for. I'll try changing the listening port. What exactly does "DHT" stand for? What does it do? Thanks for your reply! -Eric Quote Link to post Share on other sites

EricRF Posted July 21, 2014 Author Report Share Posted July 21, 2014 Distributed Hash Table - Wikipedia entryAh, interesting! I changed the listening port on BitTorrent Sync, and I'm still getting attempts to contact various IP addresses. The folders don't have DHT enabled. The folder settings and BS's preference are attached. Question: I'm seeing lots of cases of BS trying to contact lots of seemingly random (DHT?) IP addresses. Is that a result of the DHT sites sending packets to BS on my machine, and BS trying to answer? Or is BS reaching out all on its own? In any case, it's still happening Thanks for your help!

RomanZ Posted August 6, 2014 Report Share Posted August 6, 2014 @EricRF When you turn off DHT, it still might response requests from other DHT nodes. However, it should not happen once you've changed the listening port. Could you please send me a traffic capture? I'll analyze what kind of packets Sync is sending.

Where is that information logged? Thanks! Quote Link to post Share on other sites
Helen Posted August 7, 2014 Report Share Posted August 7, 2014 EricRF, Where is that information logged? In Little Snitcher, where you saw it. Capture Sync's traffic (Snitcher should save it as a .pcap file) and send it to syncapp@bittorrent.com. In the message, please, put link to this topic. I would also appreciate it if you mentioned your known peers and their IPs to exclude them from analysis. Thank you! Quote Link to post Share on other sites
