* fix(port-forward): keep the KCP handle alive and send a close reason A port forward whose connection was won by a UDP punch (KCP) died right after login. `Client::start` returns, next to the stream, the KCP handle that drives the stream's UDP I/O, and both login functions dropped it on return, so the stream failed with "stream closed" on first use. The handle now goes with the stream to whichever task owns it: the raw pipe's task, `run_legacy`'s task, or `tunnel_loop`. Closing such a stream needs care as well. KCP's FIN is sent by the handle's own tasks and dies with the handle, so the peer would hold the connection until its own timeout. A KCP tunnel closed from this side now sends a close reason first, as the remote session does. The port-forward window's io_loop passes Close on to every mapping and waits 100ms before its runtime is dropped, so the tunnels get to send it; a login that receives the Close now ends instead of swallowing it. Known limits: the raw pipe (a peer without mux) cannot carry a close reason after `set_raw`, and exits during login send none. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(port-forward): say what the close-reason send bound covers The bound on sending the close reason keeps that step inside the window's wait, but a data send already in flight in another arm of `tunnel_loop` is not bounded by it and holds the close until it returns. The comment said the whole close fit; say which part does. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>

Yet another remote desktop solution, written in Rust. Works out of the box with no configuration required. You have full control of your data, with no concerns about security. You can use our rendezvous/relay server, set up your own, or write your own rendezvous/relay server.
RustDesk welcomes contribution from everyone. See CONTRIBUTING.md for help getting started.
Dependencies
Desktop versions use Flutter or Sciter (deprecated) for GUI. This tutorial is for Sciter only, since it is easier and more friendly to start. Check out our CI for building the Flutter version.
Please download Sciter dynamic library yourself.
Raw Steps to build
-
Prepare your Rust development env and C++ build env
-
Install vcpkg, and set
VCPKG_ROOTenv variable correctly- Windows: vcpkg install libvpx:x64-windows-static libyuv:x64-windows-static opus:x64-windows-static aom:x64-windows-static
- Linux/macOS: vcpkg install libvpx libyuv opus aom
-
run
cargo run

How to build with Docker
Begin by cloning the repository and building the Docker container:
git clone https://github.com/rustdesk/rustdesk
cd rustdesk
git submodule update --init --recursive
docker build -t "rustdesk-builder" .
Then, each time you need to build the application, run the following command:
docker run --rm -it -v $PWD:/home/user/rustdesk -v rustdesk-git-cache:/home/user/.cargo/git -v rustdesk-registry-cache:/home/user/.cargo/registry -e PUID="$(id -u)" -e PGID="$(id -g)" rustdesk-builder
Note that the first build may take longer before dependencies are cached, subsequent builds will be faster. Additionally, if you need to specify different arguments to the build command, you may do so at the end of the command in the <OPTIONAL-ARGS> position. For instance, if you wanted to build an optimized release version, you would run the command above followed by --release. The resulting executable will be available in the target folder on your system, and can be run with:
target/debug/rustdesk
Or, if you're running a release executable:
target/release/rustdesk
Please ensure that you run these commands from the root of the RustDesk repository, or the application may not find the required resources. Also note that other cargo subcommands such as install or run are not currently supported via this method as they would install or run the program inside the container instead of the host.
