build-windows / build-hello-agent-x64 (push) Successful in 5m41s
A single-binary, Flutter-free remote-support agent that speaks the stock
RustDesk wire protocol. Designed for one-line MDM deployment against a
self-hosted rustdesk-server: a supporter using the unmodified rustdesk.exe
client connects, the controlled-side user gets a native Win32 approval
prompt, click Yes / No.
CLI surface
hello-agent.exe --install # register + start service
hello-agent.exe --uninstall # stop, delete, clean up
hello-agent.exe --config <BLOB> # admin-UI deploy string
hello-agent.exe --install --config <BLOB> # MDM one-liner
--config accepts both forms emitted by the rustdesk-server admin UI: the
reversed-base64 deploy string and the host=,key=,api=,relay= filename
form. Decoded via the upstream custom_server module, persisted via
hbb_common::config::Config::set_option.
Architecture
--service runs as a Session 0 LocalSystem service. It polls
WTSGetActiveConsoleSessionId and (re)spawns hello-agent.exe --server
into the active console session via librustdesk::platform::run_as_user,
handling the Session 0 → user-session token impersonation.
--server is the worker. It boots three concurrent components:
1. cm_popup: an IPC listener on the rustdesk `_cm` named pipe
2. librustdesk::start_server(true, false): the upstream protocol
stack — rendezvous mediator, NAT punch, IPC server, screen
capture, login validation, hbbs_http heartbeat / sysinfo sync
3. (implicit) ApproveMode::Click is pinned in config, so every
incoming connection routes through cm_popup
The popup mechanism reuses an existing upstream contract without any
patches to the protocol code: when a peer connects with no password,
Connection::start in the upstream code calls try_start_cm_ipc, which
ipc::connect-s the `_cm` pipe before falling back to spawning a Flutter
CM child. Since cm_popup is up first, step 1 succeeds; we read the
Data::Login{authorized:false} frame, show MessageBoxTimeoutW (Yes/No,
60s, top-most, system-modal), and reply Data::Authorize or Data::Close.

Vendoring
The upstream RustDesk crate is vendored under vendor/rustdesk/ — full
workspace including libs/{hbb_common, scrap, enigo, clipboard,
virtual_display, remote_printer}. This makes the build self-contained
(no submodules, no sibling-repo checkout in CI) and gives us freedom to
fork in a different direction later. Excluded from the vendor: .git,
target/, flutter/, appimage/, flatpak/, fastlane/, docs/, examples/,
ci/, build.py, Dockerfile, upstream README/CLAUDE/AGENTS/GEMINI.
One local divergence vs. upstream: vendor/rustdesk/src/lib.rs flips
`mod custom_server` → `pub mod custom_server` so config_import.rs can
call get_custom_server_from_string without going through the
ui_interface shim. Documented in README.md → "Re-syncing the vendored
copy".
CI
.gitea/workflows/build-windows.yml builds on a self-hosted Windows
runner with Rust 1.75, LLVM 15.0.6 (libclang for bindgen via libvpx-sys),
and a vcpkg cache. The vendored vcpkg.json drives x64-windows-static
deps. The workflow stages the resulting hello-agent.exe into
SignOutput\, reports authenticode signing status (warns on unsigned),
and uploads as artifact. ~15 min full build, faster on incremental.
Out of scope for this commit: Linux/macOS builds, code signing, MSI
packaging, coexistence with stock rustdesk on the same box (currently
shares the RustDesk APP_NAME and config dir).
