• platform: Ubuntu18.04
• error

When executing the AppImage, I encountered the following error:

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb.

Aborted (core dumped)

Thanks for your great work and looking forward to your suggestions!

Even If I change default port to any other port or starting app with or without admin credentials I get that error.

Thank for you a great project.

An enhancement I feel would be popular is a command line only version of the receiver. Such that it could be left running as a background process, maybe with some flags to specify the download directory, accept anonymous connections, etc

Currently it seems as if it requires an X display of some kind, which is unusable for headless systems or systems that don't have a display environment.

When transferring file on the mobile app, files are copied into whatever photos/videos app is there. It seems than LANDrop keeps a copy.
I could understand the want for such a feature but it would be better if it was a setting so it's more visible, and also a "select all" or "delete all" button would be nice.

I just found out that LANDrop was using 5GB on my device and was very surprised as to why.

ios最新版，只能接收PC上传来的文件，无法给PC发送文件

I downloaded the latest AppImage (as of 06/12/2021) to ~/.local/bin, provided executable permission, and then added the desktop entry in ~/.local/share/applications.

When I try to open the application using the icon from launcher, nothing happens. I just get a notification saying "LANDrop is launched here".
When I try to open it once again, I get an error message saying port 52637 is already in use.

Checked running process and killed both instances of AppRun.wrapped.

Tried starting the application using the AppImage directly. Same result.

OS: Ubuntu 20.04.2 LTS (Focal Fossa)

Transferred files losing their extra attributes (like +x flag on executables).
This is much more painful on Haiku, where the files can have tons of extra attributes. Any way to support to transfer them too?

Is it possible to add the feature of sending text directly between devices? Otherwise you have to create a text file to share text. It is especially inconvenient on iOS devices.

I transferred some files from a linux pc to an android 11 smartphone. File transfer seemed to complete normally.
Now I cannot locate the received files on the smartphone device.
What's the damn use of such an stateless app. Calling it stateless since it does not even retain the name of transferred files nor the chosen client name. Pretty major issues IMO.

Hi,
I like to use LANDrop from iPhone 5 (12.5.4) to SE (iOS 14.6).
But did not see any Devices, both enabled : discoverable

iPhone5:

iPhone SE:

How to fix ?

这软件收取文件似乎很特殊 (是否临时文件？)，因为接受之后找不到文件的路径的，必须「Share」之后选择文件管理器再去保存。

是否可以像 Mac 一样，设置文件的默认接收路径，直接保存到指定的目录？

Where is the configuration file of the LANDrop software under the windows platform? I set a wrong listening port, and now the software cannot be started, how to delete the configuration information

Installation error message: Your system needs to support tray ICONS

url scheme is convenient on iOS.

Can you release an AppImage but for qlibc_2.28 which current in Stable Debian ??

Thanks.

The following text has been translated by translation software:
I can't send files to the PC on my Android phone. I added a file by clicking in the upper right corner, and then clicked on the computer logo. Nothing happened. I'm sure the two machines are under the same local area network, because at the same time, the PC can transmit files to the mobile phone.

原文：
我无法在安卓手机上向 PC 发送文件。我通过点击右上角添加了文件，再点击电脑的标识，什么都没有发生。我确定两台机器在同一局域网下，因为与此同时 PC 可以给手机传输文件。

Could you please consider to provide Debian package? If you are interested, I already made a packaging.

1、添加快捷键弹出发送页面
2、在文件右键菜单栏添加直接发送文件
3、禁止软件运行多个实例

Just installed LANDrop through AUR and getting the above error on launch.

I am on Manjaro Linux with Gnome DE (3.38).

Any pointers on how to fix this?

LANDrop whitch is Iphone's app can find my PC,but can not connect my PC.What's it worry?
Everything is ok,only this is problem.

I tried a lot to share files between an iPhone and a Linux PC but without success 😞
In the issue tracker there are very similar problems like (#34, #35, #40, #14, etc.).
To solve these issues it would really help to be able to access error/debug logs & messages.

So my questions:

1. Is it possible to enable a debug mode in the Mobile app?
2. Is it possible to enable a debug mode in the Desktop app?

Firstly, LanDrop is the best sending files app I ever used under internal network. Highly appreciated

But I found a bug while I use phone to send files to PC via LanDrop. App in phone can find PC but cannot send files. On the contact, PC send any files successfully to phones. I had test Android and iOS phone, this bug occurs in this two platform. I didnt have any MacOS so cannot provide proof if there were in MacOS
Plus, this bug occur whilePC is lan connecting. After PC switched to WiFi, everything is OK.

Hope it will be fixed and thanks 4 ur contribution

https://doc.qt.io/qt-5/qtcpserver.html#listen
Tells the server to listen for incoming connections on address address and port port. If port is 0, a port is chosen automatically. If address is QHostAddress::Any, the server will listen on all network interfaces.

求助：当内网是由tailscale vpn建立时，设备之间无法互相发现。
然后手机APP上也没有手动填IP的位置，我也没第二台电脑，所以我也无法测试在这种情况下，手动填IP端口，landrop是否能用。但是内网肯定是建立起来了，因为我的SMB和RDP都是能正常使用的。VPN配置自身也没对端口出入做限制。都是全部放开。
（哦，如果是用路由器建立的192.168.1.x这种网段，landrop我这是能使用的，速度也能跑满，所以我本地客户端应该都没问题）

然后tailscale分配的IP是这样的

• 100.88.192.114
• 100.119.187.102
• 100.82.1.83
• 100.101.163.101

综上，谢谢:D

I am unsure whether LANDrop is (at least on the sending side) is browser or app-based.

So if someone (e.g. on an iPhone or Android Smartphone) wants to send me a file: Is it required to install LANDrop on his device?
Or can he just drop it on his browser?

Installing LANdrop App on MY local Smartphone would be acceptable.

It's successful when I trying to sending 35 files from Android to MacOS, but failed when sending massive files.

I have the scenario for syncing massive photos from phone to Mac. Sometime one directory may contains massive files, which makes selecting files one by one almost impossible . So I use 'SELECT ALL' function for adding files, and the error comes with "the receiving device closed the connection". I confirmed this error only comes when I am trying to sending massive files.

If LANDrop supports sending directory feature also can fix this problem for this scenario.

好用,希望继续开发

There is no problem when I transfer files from Windows to macOS, but when I transfer files from macOS to Windows, I got: the remote host closed the connection

What should I do in this case?

Hello team

When I try to launch for the first time Landrop 0.4 on my debian 10.10, I receive in terminal output this message 👍

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb.

First, libsodium is installed and I even try with installation of full qt platform, anyway Landrop don't start ...

could someone help me?

I saw that it works well on debian 11, but for the moment debian 11 is too new for some things I use.

Best Regard,

Mtxrider.

As a user, I would like to be able to send files by using the standard iOS share sheet. For example, if I am in the photos app:

1. Select photo
2. Click the share icon
3. Select LANDrop app
4. A window would appear allowing me to select the destination device

The next time I do this, the last device selected would be default.

Please see example from Discord

Erorr message pop up when opening the app: 无法绑定端口 52637。你的设备将无法被发现。

Such as Yoink app

landrop:// can't open landrop from safari
wechat:// 可以打开微信

iOS系统

从win10传96mb的视频到苹果手机，每次传60mb就失败了，实验多次都不成功。

• The encryption layer seems to be packet-based, with no sequencing at all
• The protocol exchanges a list of files with sizes first (Handshake2), then enters a send/receive loop:
  • Sender sends TRANSFER_QUANTA (64K) of data in an encrypted packet
  • Receiver writes that data into the first file of the file list
  • If that file is full (file size reached), it goes to the next file
    • Btw. if a file is truncated during the transfer on the sending side, it would seem like it's going to hang forever in the sender: https://github.com/LANDrop/LANDrop/blob/master/LANDrop/filetransfersender.cpp#L97

But because there is no sequencing, it would seem rather trivial for packets to be swapped around (especially for small files), which would then change the contents of files.

I sent the app for proposal on F-Droid so that it can be compiled and unstable from this repository.

If you don't want it I can delete the proposal!

Thanks for reading 😊

I know this is called 'LANdrop' but what if your phones are not on the same LAN, but are close to each other. Could you add the ability to use bluetooth to do the filetransfer?

My use case is ... I'm at a b-day party or other group event, and everyone has been taking photos/videos. Would love to have an easy way to share (full-size) photos/videos which each other. Whatsapp/Messenger etc all reduce quality of the photos when they sent them.

Bonus if you could somehow create a p2p bucket --where everyone can dump their files into, and everyone sync's to each other, as long as one client has a copy of all the files. Almost like an instant torrent, but whose contents can change dynamically.

Just my crazy ideas....

Usecase: Sending 5 GB from Windows to Android
=> after 40% transfer I get on Android app the msg. "Error: out of memory" .
fyi: I've 18 GB free flash memory, but only 1.6 GB free main memory, so it seems you're writing first into main memory, instead of directly writing to disk...
Maybe you can change this behavior?

PS: Sending only 1 GB is working without problems.

Couldn't fix the "Connection timed out" error. On the same web in school intranet (not secured network)...
Only succeed once in file transfer when the iPadOS client also showed some error (didn't screenshot :-( )

jsDelivr can speed up GitHub, which can be used when we want to quickly get a relesse file

GitHub URL:

https://github.com/LANDrop/LANDrop-releases/blob/master/LANDrop-flutter-latest-android.apk

Use jsDelivr:

"https://github.com/" change into "https://cdn.jsdelivr.net/gh/"
"/blob/" change into "@"

https://cdn.jsdelivr.net/gh/LANDrop/LANDrop-releases@master/LANDrop-flutter-latest-android.apk

I saw this in the README:

Cross platform: when we say it, we mean it. iOS, Android, macOS, Windows, Linux, name yours.

I was looking to contribute to this since I have some ideas I would like to see in LANDrop, (great project btw), so I had a look in the repo but I don't see iOS and Android in there, but I do see them in the app stores.

Are there any plans to open source the iOS & Android apps?

As mentioned in the title, landrop's main window stays on top all the time. And not on top of the other app windows, e.g. the file selection one, but on top of ANY window.

In the image, the currently active window is the one below the main one, yet the main one blocks it and prevents the user from selecting stuff.

Tested with the appimage provided from here, on debian testing/unstable + xorg + openbox and mint 20.1 + xorg + cinnamon, producing the same results.

Hello,

from what I can see, this doesn't yet support arm64. Would you be willing to take a look at it?

Thanks

1. 电脑端加入右键发送功能。
2. 加入局域网剪贴板同步功能。类似mfiles那样。
3. 传输状态百分比显示，因为现在手机端只能看到下载了多少，没有一个状态显示下载了百分之几。
4. iOS手机端可适当收费。
5. 针对后台长时间不用会出现闪退这个问题我倒是有一个想法。就是通过可以用音频播放器让app在后台保活。就是假装软件后台在放音乐，这样iOS就不会把它杀掉了。
