Easier: install it from the Store, which also updates it.
Syncthing continuously synchronises files between your devices, privately and peer-to-peer (no cloud service in between).
- Syncthing's web GUI is on port
8384. - Its configuration, keys and database are kept next to the app, e.g.
/mnt/HD/HD_a2/Nas_Prog/_syncthing, and survive reinstalls. - Its log is
syncthing.login the app's install directory (rotated at 1MB). - Devices connect on port
22000(TCP and UDP) and find each other on the local network on UDP port21027. - Like Jellyfin and Plex on the NAS, it runs as
root. Files it creates are writable by everyone (like the NAS's shares themselves), so the NAS's users can still change them over SMB. - Anonymous usage reporting is declined on a fresh install, rather than Syncthing asking when its GUI is first opened.
- Syncthing doesn't update itself: updates come with new versions of the app, and the NAS shows an alert (and sends an email, if set up) when a new Syncthing release is out, checked weekly.
Management page
Syncthing's page in the NAS dashboard (Apps → Syncthing) shows whether it's running, its version, the NAS's device ID (which other devices add it with), its folders and their sync state, and the other devices and whether they're connected. It links to Syncthing, can restart it, can turn anonymous usage reporting off, and shows and changes the GUI password (see below). Only NAS admins can use the page (see Management pages).
Logging in
Log in as admin. A random password is generated on first install and saved, readable by root only, in Nas_Prog/_syncthing/gui_password on the install volume. The management page shows it, and can change it to one you choose or a generated one (e.g. cat /mnt/HD/HD_a2/Nas_Prog/_syncthing/gui_password over SSH works too).
The GUI is reachable from the whole network and Syncthing can read and write anywhere on the NAS, so it always has a password. It can also be changed in Syncthing's own settings (Actions → Settings → GUI), but Syncthing only stores it hashed, so the management page can't show a password changed there.
Adding folders
The app doesn't create Syncthing's usual default folder: add the folders you want to share in the GUI, using their full path on the NAS, e.g. /mnt/HD/HD_a2/<share>/<folder>.
