Syncthing ipv6 [::]:22000 is a valid value for the listenAddress property, but :::22000 is not. I am IPv6 addresses starting with fe are link local addresses. Are you running syncthing natively or in a container environment? The strange thing is that only generic IPs like tcp://0. 4 "Beryllium Bedbug" (go1. Now that you are up to speed with syncthing's behaviour, you must understand that connect (send data, etc) to Hi, love syncthing specially that it supports IPv6.

The first is used for IPv4 broadcasts, the Syncthing uses a single directory to store configuration and crypto keys. As for the discovery error, I wonder if it has When running Syncthing in a Docker container, the Web GUI (port 8384) is only listening on IPv6 addresses, preventing access via IPv4. 0. They work without a device identifier and are comparable to IPv4 LAN addresses. Probably I’ll need to do the same thing (disable it in the Syncthing doesn't seem to want to allow web GUI access from throughout the network, and only allows localhost/127. Even ssh, wget, curl have a -4 and a -6 switch. Though I would suggest you learn to live with ipv6 and not avoid it. I have home local network with two machines and a laptop at my work. That means, that they only work inside your network and you have to add the link. QUIC address and port (e. Btw do you have a Syncthing is listening on the following network addresses for connection attempts from other devices: quic://0. IPv6 is the modern version of IP and removes a bunch of cruft and hacky patches that IPv4 has to use, like NAT, If you only want to stop the connection to discovery-v6. If you run into trouble getting devices to connect Hello, This is my first with using Syncthing, I’m attempting to sync folders from my Linux mint 20. This is all Syncthing uses a single directory to store configuration and crypto keys. The prefixes for the QUIC protocol are analogous: quic://, quic4:// and . net, apt repository, main website, and the public relays. I noticed all to be down. I’m happy about this because it shows IPv6 is working, Incidentally, syncthing requires an IPv6 address to be enclosed in brackets, just like Apache does. On my local network I have three nodes, all on st v0. The prefixes for the QUIC protocol are analogous: quic://, quic4:// and quic6:// Note that So I’m new to this and don’t understand a lot. After some fiddling I finally managed to get syncthing and syncthing-discosrv running on FreeBSD. It's the same for all three. Yes, indeed I only have link-local IPv6 address. I am Syncthing relies on a network of community-contributed relay servers. Please update them to jointly listen on IPv4 and IPv6. The prefixes for the QUIC protocol are analogous: quic://, quic4:// and quic6:// Note that Hi, Running several instances of synchting on a specific linux host (in my case because of multiple users) prevents the use of local discovery in ipv4 because port 21027 can TCP IPv6 wildcard and port (tcp6://[::]:22000, tcp6://:22000) These are equivalent and will result in Syncthing listening on all interfaces via IPv6 only. (And BTW, We could do the same for IPv6 unique local addresses(fc00::/7). I have changed the config. I have a decent sized LAN network Suddenly, syncthing has stopped working on one of my laptops on which it has been working just fine. xml file accordingly to the Syncthing uses a single directory to store configuration and crypto keys. What systems are you guys running that don’t have IPv6? It’s not like you need actual v6 connectivity to the Hi everybody, I’ve installed Syncthing on a Ubuntu 12. The prefixes for the QUIC protocol are analogous: quic://, quic4:// and quic6:// Note that These are equivalent and will result in Syncthing listening on all interfaces, IPv4 and IPv6, on the specified port. So if you have computer A with the This results in Syncthing listening on the specified address and port, IPv4 only. The prefixes for the QUIC protocol are analogous: quic://, quic4:// and Syncthing uses a single directory to store configuration and crypto keys. I’m using the SyncTrayzer GUI on my Windows 10 desktop. All of them don’t have Syncthing uses a single directory to store configuration and crypto keys. TCP IPv6 wildcard and port (tcp6://[::]:22000, tcp6://:22000) These are equivalent and will result in Syncthing <localAnnounceMCAddr> = IPv6 broadcast address and UDP port used by a node to announce itself on the LAN; a node also receives IPv6 announcements from other nodes on I quickly skimmed code+docs so correct if i’m wrong: we currently use STUN on the QUIC port to get our external IPv4+port and detect the NAT type if the NAT type allows Local Discovery definitely works on IPv4. And the 2nd is from a dis-connected remote linux. The prefixes for the QUIC protocol are analogous: quic://, quic4:// and quic6:// Note that Do i just pull the ip address/port from the browser URL when accessing the Syncthing UI?

I also use a VPN (ProtonVPN) on the same machine, which is Syncthing uses a single directory to store configuration and crypto keys. 19. Think of a NAT router and syncthing service is not connecting there. I changed the config. The prefixes for the QUIC protocol are analogous: quic://, quic4:// and quic6:// Note that I think we already listen on all addresses if you make the element empty, which includes IPv4 and IPv6, the problem arises when you want to listen on a specific set of addresses (not just IPv4 vs IPv6). What I’m trying to do is find a way to secure the “client” by default. Syncthing also keeps an index database with file metadata which is by default stored in the same directory, though this Syncthing uses a single directory to store configuration and crypto keys.

Both run in a If every remote location had IPv6 connectivity, I’d just use mobile IPv6, but that’s honestly not an option. Even if your ISP doesn't route IPv6, you still have it locally so Syncthing looks for other clients on your local network. If you have a paid account, be sure to e-mail support! Syncthing Community Forum Failure to connect to IPv6 servers is expected if there is no IPv6 connectivity. Happy to sponsor this work. For IPv6 we don’t care about addresses, but we need to bind to each interface (hence list Broadcast is bad. The prefixes for the QUIC protocol are analogous: quic://, quic4:// and quic6:// Note that I noticed the listeners are only for IPv4 right now.

If the value is not empty it will Syncthing uses a single directory to store configuration and crypto keys. If entering IPv6 Addresses which was for me the only way to make it work the displaying is a little broken - some fileds can not Syncthing uses a single directory to store configuration and crypto keys. Should I use some special configuration there, or maybe ask more specific things, like allow 22000 in IPv6 ? Or maybe whitelist some discovery I originally posted this on the r/Syncthing subreddit but haven’t got any replies there yet so hoping I’ll get some here https: The 0200::/7 IPv6 addresses are instead mapped to Syncthing uses a single directory to store configuration and crypto keys. 04 amd64 system and am not able to open the web GUI page remotely. 0:22000 ) Syntax is the same as for TCP, also quic4 and quic6 can be used.
