# Lan Mouse Agent Instructions
## Overview
Lan Mouse is an open-source Software KVM sharing mouse/keyboard input across local networks. The Rust workspace combines a GTK frontend, CLI/daemon mode, and multi-OS capture/emulation backends for Linux, Windows, and macOS.
## Core principles
- **Scope discipline.** Only implement what was requested; describe follow-up work instead of absorbing it.
- **Clarify OS behavior.** Ask when requirements touch OS-specific capture/emulation (they differ significantly).
- **Docs stay current.** Update [README.md](README.md) or [DOC.md](DOC.md) when touching public APIs or platform support.
- **Rust idioms.** Use `Result`/`Option`, `thiserror` for errors, descriptive logs, and concise comments for non-obvious invariants.
## Terminology
- **Client:** A remote machine that can receive or send input events. Each client is either _active_ (receiving events) or _inactive_ (can send events back). This mutual exclusion prevents feedback loops.
- **Backend:** OS-specific implementation for capture or emulation (e.g., libei, layer-shell, wlroots, X11, Windows, macOS).
- **Handle:** A per-client identifier used to route events and track state (pressed keys, position).
## Architecture
**Pipeline:** `input-capture``lan-mouse-ipc``input-emulation`
- **input-capture:** Reads OS events into a `Stream<CaptureEvent>`. Backends tried in priority order (libei → layer-shell → X11 → fallback). Tracks `pressed_keys` to avoid stuck modifiers. `position_map` queues events when multiple clients share a screen edge.
- **input-emulation:** Replays events via the `Emulation` trait (`consume`, `create`, `destroy`, `terminate`). Maintains `pressed_keys` and releases them on disconnect.
- **lan-mouse-ipc / lan-mouse-proto:** Protocol glue and serialization. Events are UDP; connection requests are TCP on the same port. Version bumps required when serialization changes.
- **input-event:** Shared scancode enums and abstract event types—extend here, don't duplicate translations.
## Feature & cfg discipline
- Feature flags live in root `Cargo.toml`. Gate OS-specific modules with tight cfgs (e.g., `cfg(all(unix, feature = "layer_shell", not(target_os = "macos")))`).
- Prefer module-level gating over per-function cfgs to avoid empty stubs.
- New backends: add feature in `Cargo.toml`, create gated module, log backend selection.
## Async patterns
- Tokio runtime with `futures` streams and `async_trait`. Model new flows as streams or async methods.
- Avoid blocking; use `spawn_blocking` if needed. Prefer existing single-threaded stream handling.
- `InputCapture` implements `Stream` and manually pumps backends—don't short-circuit this logic.
## Commands
```sh
cargo build --workspace # full build
cargo build -p <crate> # single crate
cargo test --workspace # all tests
cargo fmt && cargo clippy --workspace --all-targets --all-features # lint
RUST_LOG=lan_mouse=debug cargo run # debug logging
```
Run from repo root—no `cd` in scripts.
## Testing
- Unit tests for utilities; integration tests for protocol behavior.
- OS-specific backends: test via GTK/CLI on target OS or document manual verification.
- Dummy backend exercises pipeline without real dependencies.
- Verify `terminate()` releases keys on unexpected disconnect.
## Workflow
1. Clarify ambiguous requirements, especially OS-specific behavior.
2. Implement minimal change; flag follow-up work.
3. Add proportional tests; run `cargo test` on affected crates.
4. Run `cargo fmt` and `cargo clippy --workspace --all-targets --all-features`.

Lan Mouse is a *cross-platform* mouse and keyboard sharing software similar to universal-control on Apple devices.
It allows for using multiple PCs via a single set of mouse and keyboard.
Lan Mouse is a mouse and keyboard sharing software similar to universal-control on Apple devices.
It allows for using multiple pcs with a single set of mouse and keyboard.
This is also known as a Software KVM switch.
Goal of this project is to be an open-source alternative to proprietary tools like [Synergy 2/3](https://symless.com/synergy), [Share Mouse](https://www.sharemouse.com/de/)
and other open source tools like [Deskflow](https://github.com/deskflow/deskflow) or [Input Leap](https://github.com/input-leap) (Synergy fork).
Focus lies on performance, ease of use and a maintainable implementation that can be expanded to support additional backends for e.g. Android, iOS, ... in the future.
***blazingly fast™*** because it's written in rust.
The primary target is Wayland on Linux but Windows and MacOS and Linux on Xorg have partial support as well (see below for more details).

## Encryption
Goal of this project is to be an open-source replacement for proprietary tools like [Synergy](https://symless.com/synergy), [Share Mouse](https://www.sharemouse.com/de/).
Lan Mouse encrypts all network traffic using the DTLS implementation provided by [WebRTC.rs](https://github.com/webrtc-rs/webrtc).
There are currently no mitigations in place for timing side-channel attacks.
Focus lies on performance and a clean, manageable implementation that can easily be expanded to support additional backends like e.g. Android, iOS, ... .
***blazingly fast™*** because it's written in rust.
For an alternative (with slightly different goals) you may check out [Input Leap](https://github.com/input-leap).
## OS Support
Most current desktop environments and operating systems are fully supported, this includes
- GNOME >= 45
- KDE Plasma >= 6.1
- Most wlroots based compositors, including Sway (>= 1.8), Hyprland and Wayfire
- Windows
- MacOS
The following table shows support for input emulation (to emulate events received from other clients) and
input capture (to send events *to* other clients) on different operating systems:
| Backend | input emulation | input capture |
|---------------------------|--------------------------|--------------------------------------|
| Wayland (wlroots) | :heavy_check_mark: | :heavy_check_mark: |
| Wayland (KDE) | :heavy_check_mark: | :heavy_check_mark: |
| Wayland (Gnome) | :heavy_check_mark: | WIP |
| X11 | :heavy_check_mark: | WIP |
| Windows | :heavy_check_mark: | WIP |
| MacOS | ( :heavy_check_mark: ) | WIP |
### Caveats / Known Issues
Keycode translation is not yet implemented so on MacOS only mouse emulation works as of right now.
> [!Important]
> - **X11** currently only has support for input emulation, i.e. can only be used on the receiving end.
>
> - **Sway / wlroots**: Wlroots based compositors without libei support on the receiving end currently do not handle modifier events on the client side.
> This results in CTRL / SHIFT / ALT / SUPER keys not working with a sending device that is NOT using the `layer-shell` backend
>
> - **Wayfire**: If you are using [Wayfire](https://github.com/WayfireWM/wayfire), make sure to use a recent version (must be newer than October 23rd) and **add `shortcuts-inhibit` to the list of plugins in your wayfire config!**
> Otherwise input capture will not work.
>
> - **Windows**: The mouse cursor will be invisible when sending input to a Windows system if
> there is no real mouse connected to the machine.
For more detailed information about os support see [Detailed OS Support](#detailed-os-support)
### Android & IOS
A proof of concept for an Android / IOS Application by [rohitsangwan01](https://github.com/rohitsangwan01) can be found [here](https://github.com/rohitsangwan01/lan-mouse-mobile).
It can be used as a remote control for any device supported by Lan Mouse.

brew install libadwaita
```
The prerelease version (following `main`) is available on the AUR:
```sh
paru -S lan-mouse-git
```
</details>
<details>
<summary>Nix (OS)</summary>
- nixpkgs: [search.nixos.org](https://search.nixos.org/packages?channel=unstable&show=lan-mouse&from=0&size=50&sort=relevance&type=packages&query=lan-mouse)
- flake: [README.md](./nix/README.md)
</details>
<details>

- Unzip it
- Remove the quarantine with `xattr -rd com.apple.quarantine "Lan Mouse.app"`
- Launch the app
- Use the menu bar item to open the settings window or quit Lan Mouse. Bundled macOS builds run as a menu bar app and do not keep a Dock icon visible.
- Grant accessibility permissions in System Preferences
</details>
<details>
<summary>Manual Installation</summary>
First make sure to [install the necessary dependencies](#installing-dependencies-for-development--compiling-from-source).
Precompiled release binaries for Windows, MacOS and Linux are available in the [releases section](https://github.com/feschber/lan-mouse/releases).
For Windows, the depenedencies are included in the .zip file, for other operating systems see [Installing Dependencies](#installing-dependencies-for-development--compiling-from-source).
Alternatively, the `lan-mouse` binary can be compiled from source (see below).
### Installing desktop file, app icon and firewall rules (optional)
```sh
# install lan-mouse (replace path/to/ with the correct path)
sudo cp path/to/lan-mouse /usr/local/bin/
# install app icon
sudo mkdir -p /usr/local/share/icons/hicolor/scalable/apps
sudo cp lan-mouse-gtk/resources/de.feschber.LanMouse.svg /usr/local/share/icons/hicolor/scalable/apps
# update icon cache
gtk-update-icon-cache /usr/local/share/icons/hicolor/
# install desktop entry
sudo mkdir -p /usr/local/share/applications
sudo cp de.feschber.LanMouse.desktop /usr/local/share/applications
# when using firewalld: install firewall rule
sudo cp firewall/lan-mouse.xml /etc/firewalld/services
# -> enable the service in firewalld settings
```
Instead of downloading from the releases, the `lan-mouse` binary
can be easily compiled via cargo or nix:
### Compiling and installing manually:
```sh
# compile in release mode
cargo build --release
# install lan-mouse
sudo cp target/release/lan-mouse /usr/local/bin/
```
### Compiling and installing via cargo:
```sh
# will end up in ~/.cargo/bin
cargo install lan-mouse
```
### Compiling and installing via nix:
```sh
# you can find the executable in result/bin/lan-mouse
nix-build
```
### Conditional compilation
Support for other platforms is omitted automatically based on the active
rust toolchain.
Additionally, available backends and frontends can be configured manually via
[cargo features](https://doc.rust-lang.org/cargo/reference/features.html).
E.g. if only support for sway is needed, the following command produces
an executable with support for only the `layer-shell` capture backend
and `wlroots` emulation backend:
```sh
cargo build --no-default-features --features layer_shell_capture,wlroots_emulation
```
For a detailed list of available features, checkout the [Cargo.toml](./Cargo.toml)
</details>
## Development
### Git pre-commit hook
This repository includes a local git hooks directory `.githooks/` with a `pre-commit` script that enforces formatting, lints, and tests before allowing a commit. It is optional to enable it, but it will prevent you from committing code with failing unit tests or that needs clippy/fmt fixes. To enable the hook locally:
1. Make the hook executable:
```sh
chmod +x .githooks/pre-commit
```
2. Point git to the hooks directory (one-time per clone):
```sh
git config core.hooksPath .githooks
```
The `pre-commit` script runs `cargo fmt --all` (and fails if files were modified), `cargo clippy --workspace --all-targets --all-features -- -D warnings`, and `cargo test --workspace --all-features`.
### Dependencies & Compiling from Source
<details>
<summary>MacOS</summary>
```sh
# Install dependencies
brew install libadwaita pkg-config imagemagick
cargo install cargo-bundle
# Create the macOS icon file
scripts/makeicns.sh
# Create the .app bundle

the gtk frontend (see conditional compilation below).
### Build and run
Build in release mode:
```sh
cargo build --release
```
Run directly:
```sh
cargo run --release
```
### Conditional Compilation
Currently only x11, wayland, windows and MacOS are supported backends.
Depending on the toolchain used, support for other platforms is omitted
automatically (it does not make sense to build a Windows `.exe` with
support for x11 and wayland backends).
However one might still want to omit support for e.g. wayland, x11 or libei on
a Linux system.
This is possible through
[cargo features](https://doc.rust-lang.org/cargo/reference/features.html).
E.g. if only wayland support is needed, the following command produces
an executable with just support for wayland:
```sh
cargo build --no-default-features --features wayland
```
For a detailed list of available features, checkout the [Cargo.toml](./Cargo.toml)
## Usage
<details>
<summary>Gtk Frontend</summary>
### Gtk Frontend
By default the gtk frontend will open when running `lan-mouse`.
To connect a device you want to control, simply click the `Add` button and enter the hostname
of the device.
To add a new connection, simply click the `Add` button on *both* devices,
enter the corresponding hostname and activate it.
On the *remote* device, authorize your *local* device for incoming traffic using the `Authorize` button
under the "Incoming Connections" section.
The fingerprint for authorization can be found under the general section of your *local* device.
It is of the form "aa:bb:cc:..."
If the mouse can not be moved onto a device, make sure you have port `4242` (or the one selected)
opened up in your firewall.
Authorized devices can be persisted using the configuration file (see [Configuration](#configuration)).
### Command Line Interface
The cli interface can be enabled using `--frontend cli` as commandline arguments.
Type `help` to list the available commands.
If the device still can not be entered, make sure you have UDP port `4242` (or the one selected) opened up in your firewall.
</details>
<details>
<summary>Command Line Interface</summary>
The cli interface can be accessed by passing `cli` as a commandline argument.
Use
E.g.:
```sh
lan-mouse cli help
$ cargo run --release -- --frontend cli
(...)
> connect <host> left|right|top|bottom
(...)
> list
(...)
> activate 0
```
to list the available commands and
```sh
lan-mouse cli <cmd> help
```
for information on how to use a specific command.
</details>
<details>
<summary>Daemon Mode</summary>
Lan Mouse can be launched in daemon mode to keep it running in the background (e.g. for use in a systemd-service).
To do so, use the `daemon` subcommand:
### Daemon
Lan Mouse can be launched in daemon mode to keep it running in the background.
To do so, add `--daemon` to the commandline args:
```sh
lan-mouse daemon
$ cargo run --release -- --daemon
```
</details>
## Systemd Service
In order to start lan-mouse with a graphical session automatically,
the [systemd-service](service/lan-mouse.service) can be used:
Copy the file to `~/.config/systemd/user/` and enable the service:
```sh
cp service/lan-mouse.service ~/.config/systemd/user
systemctl --user daemon-reload
systemctl --user enable --now lan-mouse.service
```
> [!Important]
> Make sure to point `ExecStart=/usr/bin/lan-mouse daemon` to the actual `lan-mouse` binary (in case it is not under `/usr/bin`, e.g. when installed manually.

## Protocol
Currently *all* mouse and keyboard events are sent via **UDP** for performance reasons.
Each event is sent as one single datagram, currently without any acknowledgement to guarantee 0% packet loss.
This means, any packet that is lost results in a discarded mouse / key event, which is ignored for now.
**UDP** also has the additional benefit that no reconnection logic is required.
Any client can just go offline and it will simply start working again as soon as it comes back online.
Additionally a tcp server is hosted for data that needs to be sent reliably (e.g. the keymap from the server or clipboard contents in the future) can be requested via a tcp connection.
## Bandwidth considerations
The most bandwidth is taken up by mouse events. A typical office mouse has a polling rate of 125Hz
while gaming mice typically have a much higher polling rate of 1000Hz.
A mouse Event consists of 21 Bytes:
- 1 Byte for the event type enum,
- 4 Bytes (u32) for the timestamp,
- 8 Bytes (f64) for dx,
- 8 Bytes (f64) for dy.
Additionally the IP header with 20 Bytes and the udp header with 8 Bytes take up another 28 Byte.
So in total there is 49 * 1000 Bytes/s for a 1000Hz gaming mouse.
This makes for a bandwidth requirement of 392 kbit/s in total _even_ for a high end gaming mouse.
So bandwidth is a non-issue.
Larger data chunks, like the keymap are offered by the server via tcp listening on the same port.
This way we dont need to implement any congestion control and leave this up to tcp.
In the future this can be used for e.g. clipboard contents as well.
## Packets per Second
While on LAN the performance is great,
some WIFI cards seem to struggle with the amount of packets per second,
particularly on high-end gaming mice with 1000Hz+ polling rates.
The plan is to implement a way of accumulating packets and sending them as
one single key event to reduce the packet rate (basically reducing the polling
rate artificially).
The way movement data is currently sent is also quite wasteful since even a 16bit integer
is likely enough to represent even the fastest possible mouse movement.
A different encoding that is more efficient for smaller values like
[Protocol Buffers](https://protobuf.dev/programming-guides/encoding/)
would be a better choice for the future and could also help for WIFI connections.
## Security
Sending key and mouse event data over the local network might not be the biggest security concern but in any public network or business environment it's *QUITE* a problem to basically broadcast your keystrokes.
- There should be an encryption layer below the application to enable a secure link.
- The encryption keys could be generated by the graphical frontend.
## Detailed OS Support
## Wayland support
### Input Emulation (for receiving events)
On wayland input-emulation is in an early/unstable state as of writing this.
In order to use a device for sending events, an **input-capture** backend is required, while receiving events requires
a supported **input-emulation** *and* **input-capture** backend.
For this reason a suitable backend is chosen based on the active desktop environment / compositor.
A suitable backend is chosen automatically based on the active desktop environment / compositor.
Different compositors have different ways of enabling input emulation:
The following sections detail the emulation and capture backends provided by lan-mouse and their support in desktop environments / operating systems.
#### Wlroots
Most wlroots-based compositors like Hyprland and Sway support the following
unstable wayland protocols for keyboard and mouse emulation:
- [virtual-keyboard-unstable-v1](https://wayland.app/protocols/virtual-keyboard-unstable-v1)
- [wlr-virtual-pointer-unstable-v1](https://wayland.app/protocols/wlr-virtual-pointer-unstable-v1)
### Input Emulation Support
#### KDE
KDE also has a protocol for input emulation ([kde-fake-input](https://wayland.app/protocols/kde-fake-input)),
it is however not exposed to third party applications.
| Desktop / Backend | wlroots | libei | remote-desktop portal | windows | macos | x11 |
|---------------------------|--------------------------|--------------------------|--------------------------|--------------------------|----------------------------------------|--------------------|
| Wayland (wlroots) | :heavy_check_mark: | | | | | |
| Wayland (KDE) | | :heavy_check_mark: | :heavy_check_mark: | | | |
| Wayland (Gnome) | | :heavy_check_mark: | :heavy_check_mark: | | | |
| Windows | | | | :heavy_check_mark: | | |
| MacOS | | | | | :heavy_check_mark: | |
| X11 | | | | | | :heavy_check_mark: |
The recommended way to emulate input on KDE is the
[freedesktop remote-desktop-portal](https://flatpak.github.io/xdg-desktop-portal/#gdbus-org.freedesktop.portal.RemoteDesktop).
- `wlroots`: This backend makes use of the [wlr-virtual-pointer-unstable-v1](https://wayland.app/protocols/wlr-virtual-pointer-unstable-v1) and [virtual-keyboard-unstable-v1](https://wayland.app/protocols/virtual-keyboard-unstable-v1) protocols and is supported by most wlroots based compositors.
- `libei`: This backend uses [libei](https://gitlab.freedesktop.org/libinput/libei) and is supported by GNOME >= 45 or KDE Plasma >= 6.1.
- `xdp`: This backend uses the [freedesktop remote-desktop-portal](https://flatpak.github.io/xdg-desktop-portal/#gdbus-org.freedesktop.portal.RemoteDesktop) and is supported on GNOME and Plasma.
- `x11`: Backend for X11 sessions.
- `windows`: Backend for Windows.
- `macos`: Backend for MacOS.
#### Gnome
Gnome uses [libei](https://gitlab.freedesktop.org/libinput/libei) for input emulation and capture,
which has the goal to become the general approach for emulating and capturing Input on Wayland.
### Input capture
To capture mouse and keyboard input, a few things are necessary:
- Displaying an immovable surface at screen edges
- Locking the mouse in place
- (optionally but highly recommended) reading unaccelerated mouse input
### Input Capture Support
| Required Protocols (Event Emitting) | Sway | Kwin | Gnome |
|----------------------------------------|--------------------|----------------------|----------------------|
| pointer-constraints-unstable-v1 | :heavy_check_mark: | :heavy_check_mark: | :heavy_check_mark: |
| relative-pointer-unstable-v1 | :heavy_check_mark: | :heavy_check_mark: | :heavy_check_mark: |
| keyboard-shortcuts-inhibit-unstable-v1 | :heavy_check_mark: | :heavy_check_mark: | :heavy_check_mark: |
| wlr-layer-shell-unstable-v1 | :heavy_check_mark: | :heavy_check_mark: | :x: |
| Desktop / Backend | layer-shell | libei | windows | macos | x11 |
|---------------------------|--------------------------|--------------------------|--------------------------|----------------------------------------|-----|
| Wayland (wlroots) | :heavy_check_mark: | | | | |
| Wayland (KDE) | :heavy_check_mark: | :heavy_check_mark: | | | |
| Wayland (Gnome) | | :heavy_check_mark: | | | |
| Windows | | | :heavy_check_mark: | | |
| MacOS | | | | :heavy_check_mark: | |
| X11 | | | | | WIP |
The [zwlr\_virtual\_pointer\_manager\_v1](wlr-virtual-pointer-unstable-v1) is required
to display surfaces on screen edges and used to display the immovable window on
both wlroots based compositors and KDE.
Gnome unfortunately does not support this protocol
and [likely won't ever support it](https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/1141).
~In order for layershell surfaces to be able to lock the pointer using the pointer\_constraints protocol [this patch](https://github.com/swaywm/sway/pull/7178) needs to be applied to sway.~
(this works natively on sway versions >= 1.8)
- `layer-shell`: This backend creates a single pixel wide window on the edges of Displays to capture the cursor using the [layer-shell protocol](https://wayland.app/protocols/wlr-layer-shell-unstable-v1).
- `libei`: This backend uses [libei](https://gitlab.freedesktop.org/libinput/libei) and is supported by GNOME >= 45 or KDE Plasma >= 6.1.
- `windows`: Backend for input capture on Windows.
- `macos`: Backend for input capture on MacOS.
- `x11`: TODO (not yet supported)

# Nix Flake Usage
## Run
```bash
nix run github:feschber/lan-mouse
# With params
nix run github:feschber/lan-mouse -- --help
```
## Home-manager module
Add input:
```nix
inputs = {
lan-mouse.url = "github:feschber/lan-mouse";
}
```
Optional: add [our binary cache](https://app.cachix.org/cache/lan-mouse) to allow a faster package install.
```nix
nixConfig = {
extra-substituters = [
"https://lan-mouse.cachix.org/"
];
extra-trusted-public-keys = [
"lan-mouse.cachix.org-1:KlE2AEZUgkzNKM7BIzMQo8w9yJYqUpor1CAUNRY6OyM="
];
};
```
Enable lan-mouse:
``` nix
{
inputs,
...
}: {
# Add the Home Manager module
imports = [inputs.lan-mouse.homeManagerModules.default];
programs.lan-mouse = {
enable = true;
# systemd = false;
# package = inputs.lan-mouse.packages.${pkgs.stdenv.hostPlatform.system}.default
# Optional configuration in nix syntax, see config.toml for available options
# settings = { };
};
};

Lan Mouse is a mouse and keyboard sharing software similar to universal-control on Apple devices. It allows for using multiple pcs with a single set of mouse and keyboard. This is also known as a Software KVM switch.
The primary target is Wayland on Linux but Windows and MacOS and Linux on Xorg have partial support as well (see below for more details).
