Just installed Syncthing on my Scale server. It looks like it doesn’t have users but rather folder IDs that are then used to sync devices. One of the cool features of Nextcloud is the ability to share files with other users. Can this be done with Syncthing?
IP should not cause any issues. IDs are just a hash of certificate used by Syncthing. Can you elaborate a little on the current setup? Device, OS, User, etc. Also if possible can you explain your use case? As I mentioned, Syncthing is very specific to what it can do, so it may not be the best solution for your case.
Server is Truenas Scale. Syncthing is running as app. I and wife have it installed on Android phones. We both share a Debian 12 laptop with different logins. We both want to keep respective phone synced with laptop login. We want to have a folder shared on nas where we can exchange files.
