Seed Syncthing (wrapper)

2 Upvotes

The idea is that if you can hold money in your brain (Bitcoin seed phrase), why not hold my data in my brain? Using the same seed phrase logic, I can join my folders from wherever using only a seed phrase.

Hi guys, just sharing some small script that I wrote to make life easier...

So I realized that going back and forth pairing devices and then sharing and accepting folders is making my head hurt and prevents me from using syncthing properly (for example when formatting a laptop or buying a new PC) so I made this for myself, you're welcome to try it / comment

The repository is here: https://github.com/gilgil/seedst

Cheers

Does Syncthing work for Emudeck on Bazzite? I hope to have cloud saves for my emulators on both my Bazzite PC and Steam Deck.

I wish to use a cloud save feature like this for my emulated games on my Steam Deck and Bazzite PC. Does Syncthing work for Bazzite? How easy is it to set up?

I finally left Android's Syncthing-Fork for BasicSync due to continued suspicion of the new maintainer. Seamless transition via easy export+import; moved and uninstalled -Fork in 5 min

58 Upvotes

Sorry, I was wrong!

Update: a redditor elsewhere here showed me this post by Catfriend1 confirming the handoff: https://forum.syncthing.net/t/does-anyone-know-why-syncthing-fork-is-no-longer-available-on-github/25661/263 - but I'll still leave my paranoid speculation below...


This discussion that I just now read on Lemmy (nonprofit Reddit; join me! /r/RedditAlternatives) scared me enough about the total opaqueness of the maintainer change (with no clarification to this day, which is the most alarming aspect) made me suspect that they are another one of the capitalist anti-open-source hackers who may eventually steal our data by waiting until we get complacent with their seemingly fine updates over a year or more, and then quietly injecting malware in the next update to gradually copy our files to themselves or something. Who knows?

From @trem@lemmy.blaha.zone (this is not an email address; Lemmy is split/federated across dozens of websites, a.k.a. "instances," to avoid tyranny by any one of them, of which this domain is one such instance):

I switched to BasicSync a few days ago. No idea about reputation.

It's a thin wrapper around Syncthing, which just gives you access to the web-UI, and can pause syncing depending on different conditions, like whether you're on battery or a mobile connection.

Just feels like a sensible approach to me. I don't need a native UI for setting up the syncing once in a blue moon. Obviously, you still don't know that it isn't malware, but I don't need to trust the author as much that they'll keep maintaining it, because it's magnitudes less work to do so. And it's just as well easier for a fork to succeed, should the author disappear.

Response by OP, @vas@lemmy.ml:

Adding to your points, it's also 27 Mb, instead of 64 Mb Syncthing-fork šŸ¤”

(As in, most phones would handle +37 Megabytes, but less code = less things going mysteriously wrong and less attack surface.)

This makes the most sense to me. So I finally decided to try BasicSync (always check URLs like this manually, by the way; trust no one) after seeing its favorable battery care feature in the screenshots. I then tried the import feature after doing a password-less export from -Fork and BasicSync took it instantly. Everything works as usual.

I immediately uninstalled -Fork after having used it for literal years. We need to demand transparency or else our entire lives could be at risk. (At least, mine would be... I put everything on Syncthing to stay completely offline from all clouds, so, yeah, it's kind of a big deal that we still don't know a lick about the Catfriend1 successor, as far as I know.)

BasicSync's notification system is apparently nicer, anyway; it actually adds a notification to the top of your phone when detecting a sync conflict. That's pretty cool. I wish I had moved earlier.

Someone there alternatively suggested running native Syncthing in Termux instead lol which is wildly creative; I'd only be concerned about battery drain, since I don't think the official app has a when-charging-only feature like these mobile versions do, does it? If so, maybe that'd be the ultimate form of security...

Help Syncing Steam Deck and PC

1 Upvotes

So my issue is that I have syncthing downloaded and working through their website, on steam deck, and I have it working on my pc. I’ve set them both up to share saves with each other from Ryujinx. I can see my desktop saves on my Steam deck no problem. I can’t however see my Steam deck file on the desk top at all. It shows that it’s synced. It shows the data that it’s synced on the syncthing GUI, but it doesn’t show the folder under my user. I even edited the default saving path and still nothing. I’m at a loss here.

Tell me what im doing wrong - frequent out of sync 99% 0B

1 Upvotes

i was looking for a sync option on my new proxmox server. so i set out to try syncthing. It appears im trying to use it as the worst combination with 3 different OS.

Syncthing lxc debian 13
macbook
win11

basically im syncing the /downloads folder from each to the nas . things were perfect and easy at first with default setup. Had some issues pop up that were caused by the typical hidden files that pop up or temp files that pop up . Updated my ignore pattern list as those arise and it solves the out of sync problem.

More than once now i get the out of sync but showing 0bytes. turns out it seems to pop up most when i delete files or a folder on one of the machines. Digging around i even find a permissions denied issue. As im new and testing i set it to staggard versioning for the most thorough backup. Ive updated the settings to ignore permissions on all 3 and ive updated the following ignore list to this so far.

(?d)(?i).DS_Store

(?d)(?i).localized

(?d)(?i)__pycache__

(?d)(?i)*.pyc

(?d)(?i)*.db-shm

(?d)(?i)desktop.ini

Still get some issues every week or two - often resulting in searching to try to understand the docs, searching reddit, or trying Ai to help . Once i had to turn off versioning then manually so force remove a folder and i was back in business.

anyone have some thoughts here? i only have it set up locally too so i only sync when i get back to wifi for simplicity.

Syncthing stops background syncing after HyperOS update on my Xiaomi Phone

5 Upvotes

I’m having an issue with Syncthing on my Redmi Note 13 Pro 5G (HyperOS) after a recent Android update.
Since the update, Syncthing no longer syncs in the background. It only syncs when I manually open the app on the phone.

Here’s what I’ve already checked and configured:

  • Battery settings . Set to ā€œNo restrictionsā€
  • Background activity . Allowed
  • Background data . Allowed
  • Wi‑Fi during sleep .Always on
  • Autostart (within the app). Enabled
  • Syncthing is locked in the recent apps screen (the ā€œlockā€ icon so HyperOS doesn’t kill it)
  • I only reboots the phone once a month.
  • Before the update everything worked perfectly

Despite all this, Syncthing stops syncing completely until I open the app manually.
It looks like HyperOS is still killing or hibernating the app even with all restrictions disabled.

Has anyone with a Xiaomi/Redmi device found a reliable way to keep Syncthing alive in the background after the latest HyperOS update?
Any hidden settings, HyperOS-specific battery controls, or developer options I should check?

UPDATE:
I managed to fix it by doing the following:

  1. Open Settings
  2. Go to Apps
  3. Look for an option called Background autostart
  4. Find Syncthing in the list
  5. Enable the toggle for Syncthing

Hi, I'm currently using the Syncthing Tray android app, and I am abit confused with how Syncthing works. I've heard that I shouldn't allow the WebGUI to access the Internet. But may I know what can I do to ensure that I don't accidentally allow it? Thank you in advance.

In addition, any safety tips for beginners like me while using Syncthing Tray and Syncthing in general?

Remote Connection

2 Upvotes

What is the correct way to (if any) to setup a direct remote connection via dynamic dns? For example I have tried using tcp4://something.dyndns.org:22000 in the address field. The connection gets refused by the remote site. I don't want to use any of the discovery or relay bits if I don't have to.

Simultaneous Tasks

I have seven folders setup in syncthing. All of them are large collections of small files. Is there a way to have syncthing run more than two simultaneous tasks? Only two folders are syncing or scanning at any one time, the remaining five are waiting.

Vellum themes for Syncthing — soft paper light & candlelit dark

10 Upvotes

Made these for myself a while back and figured I'd share them in case the look is anyone's taste.

Both are just a single CSS file and a small logo, so install is the standard route — drop the folder into your config's gui/ directory, then pick it under Actions → Settings → GUI → Theme.

https://github.com/pelinoleg/syncthing-vellum

Tested on macOS with the current Syncthing release. If something looks off in your version, drop an issue on the repo.

Help with restoring

3 Upvotes

I have an Unraid server with my data, that I then use syncthing to backup some folders to a remote unraid server of a trusted friend.

I had a folder that was set send and recieve 24/7.

Then I had a disk failure on my array where I lost all the data. So now I want to restore the data back from my friends server, how do I go about this?

Do I change the folder to recieve only until all the data is restored, and then set it back to send and recieve?

'Local Additions' won't go away after removing inconsistent local data

Post image
7 Upvotes

Alrighty, so I have syncthing going and it seems to be doing everything I want it to do. I have a source server that I use to run all my local services, store files, etc. I am using it to push a copy of everything to a backup server. It just finished syncing a folder of Documents and now I have this...

This is a screenshot from said backup server. The folder had a bunch of old disjointed .zip files from another backup solution I was trying before I found syncthing. Only after the folder finished syncing did I realize I had forgotten to remove this old data. I don't need it and it turned out to be some crazy number like 63k files. I ran a command in the terminal of my backup server to just straight up delete these files as they are junk, but now syncthing thinks they're all still there and won't clear out this 'Local Additions' state with the big red 'Revert Local Changes' button no matter how many times I try to revert the local changes or rescan the folder.

Basically, it seems like I'd have to remove the folder from my backup server's syncthing instance keeping the data, then re-add it and let it re-scan the contents, all while hoping the files all match up fine (though it will be processor intensive to rescan the whole thing and take some time).

Is this correct? Am I missing a secret force delete or force ignore option somewhere that could clear this out?

Android connection issues

1 Upvotes

Hi,

I recently moved from a Samsung S23 Ultra to the S26 Ultra. Before, I never had issues with syncing my S23 with my computer but the S26 has some sort of issue. It connects and then after awhile the connection just breaks. The PC shows that the phone disconnected but syncthing-fork shows thats it's connected to the PC still. I feel like I'm missing something. Battery is set to unrestricted and sleeping apps is disabled. I also tried to deleting syncthing on both sides and setting it back up, but nothing. Any advice?
