i have the following problem with syncing a repository with another node.
I use syncthing v0.8.16 for x86_64 on two linux machines.
The node is detected, but the route can’t be established. Therefore the node is marked as “Disconnected” in the Web-Gui.
The output from STTRACE=net ./syncthing is the following:
main.go:645: DEBUG: dial AAAA ipAdress:21035
main.go:650: DEBUG: dial tcp ipAdress:21035: no route to host
Both nodes are in the same local network, and the resolution from the AAAA node to the correct ip-address is done well, so i don’t know where the problem is.
I would thank you for every idea for solving that problem.
What’s the actual log output, without obfuscated IP address (nor node ID, it’s notsensitive) and output from netstat -rn and ping <that ip address>? Barring weird bugs, the error should mean that the IP address in question is not reachable.
Nothing obvious jumps out. Did you set the listen port to 21035 manually on 10.0.20.11? Does a telnet 10.0.20.11:21035 connect? Any firewall on that host that might need tweaking?
thanks for the Idea with the firewall. I forgot that one system is a fedorea linux.
So first i thought selinux is getting in the way, but in the end it was like you expected the firewall(iptables) which don’t let the traffic through. Thanks
