YI WANG Posted January 12, 2017 Report Share Posted January 12, 2017 Hi, I was kind of gotten the sync among 3 clients done, until recent several days something weird happened. First please allow me to describe my Sync environment: Client 1, a CENTOS server in cloud. 24*7 RUN, with name of "Sync on aliyun". Only synced very few files b/c the disk volume is very expensive, The point is use Sync on this server is to use its public IP to help improve the connectivity among different peers. At least I thought it could help.... Client 2, a PC, windows 10 in my home, got public ip under openwrt router and opened PNP. I used this PC to work after I got off the work place. Client 3, a PC, windows 10 at my work place. Only a computer in my work place network. Nearly a hundred computer used one public IP, no ability to change the router setting, No uPNP. I used Shadowsocks and local port is 127.0.0.1:1080. I checked the option of "use proxy server" and "use proxy server" in Resilio Sync in advanced preference. 24*7 RUN. PS: i wanted to upload some pics, but found my MAX TOTAL SIZE: IS ONLY 0.03MB?? how could be possible a pic is only 30kb? So, no pics anyways. I liked to open my home pc and get synced from my OFFICE PC. But now this could not work any more. The problem is Client 2 and 3 could "see" client 1, but 2 & 3 could not 'SEE" each other, why this happened? I used Client 1's IP in client 2's & 3's advanced preference of "folders.default_known_host", I thought this would help different peer to find each other. But the truth is, which doesn't help that much. So, please, anything I would debug to change to improve my situation? Thanks in advance.

Helen Posted January 12, 2017 Report Share Posted January 12, 2017 Peers establish standard network TCP or UDP connections between each other. So recheck that between client 2 and 3. If direct is not possible, Sync will use relay. So check that both client 2 and 3 can connect to relay (TCP only) . These article can help you troubleshoot connection: https://help.getsync.com/hc/en-us/articles/204754759-What-ports-and-protocols-are-used-by-Sync-https://help.getsync.com/hc/en-us/articles/205450205-Peers-aren-t-connecting Quote Link to comment Share on other sites More sharing options...
YI WANG Posted January 12, 2017 Author Report Share Posted January 12, 2017 Thanks for replying. I think both of 2 and 3 could connect to relay server, b/c if they don't there would be a red tip below the GUI said they could not connect to the relay server, isn't it right?

YI WANG Posted January 22, 2017 Author Report Share Posted January 22, 2017 Hi, @Helen I found the connection between client 2 and 3 are no stable, most of time the connection between them would be appear to be disconnection. So, I am thinking what method would help to increase the connectivity? GitHub - xtaci/kcptun: A Simple UDP Tunnel Based On KCP I found this tools which would help to convert TCP data into UDP data, would it help? Or use VPN to make my working client PC to dispose to the Internet? I don't think folders.default_known_host is reliable, after I filled that option with my home sync's Ip and port, the connectivity didn't improve. So please give some advice. I checked everything I could do, but the connectivity is not reliable still. Quote Link to comment Share on other sites More sharing options...
YI WANG Posted January 22, 2017 Author Report Share Posted January 22, 2017 One more thing, is it OK to use the PORT 80 in my working place? I just set it to 80 and seem everything goes well.... Quote Link to comment Share on other sites More sharing options...
Helen Posted January 23, 2017 Report Share Posted January 23, 2017 If it works, then you can keep using that. It's all your network, not ours Quote Link to comment Share on other sites More sharing options...
