In relay mode, the banner now exposes a single button that calls
sessionReconnect(sessionId, forceRelay=false). This:
- resets the is_force_relay flag in the Session lc state
- triggers a fresh punch attempt (with the same direct_failures counter,
which only shortens the punch timeout, never skips the attempt)
- if punch succeeds, banner flips to green and file transfer re-enables
The button is disabled (greyed out) if sessionId is not yet known.
User's setup has both Macs with global IPv6 (2409:8a1e::, China Mobile),
but punch still falls back to relay. Common cause: CGNAT, double-NAT, or
symmetric NAT. The retry button lets the user test network conditions
without restarting the app.
Removed: my earlier attempt at main_get_logs / session_get_session_id FFI
bridges — couldn't find the right log path / session API, and the
sessionId is already exposed via RemotePage.sessionId getter.
Custom fork feature: surface NAT-punch result to the user so they know
whether the connection is going through their 21117 server (relay) or
directly between the two machines (P2P).
Three changes:
1. flutter/lib/common/shared_state.dart: add ConnectionType.isP2P getter
(true = direct, false = relay) and a top-level isDirectConnection(peerId)
helper that returns true when state is unknown (so UI doesn't briefly
grey out before the connection establishes).
2. flutter/lib/desktop/widgets/punch_status_banner.dart (new): a small
Positioned banner at the top of the connection page.
- P2P success: green ⚡ banner: 'P2P 直连成功 — 走的是两台机器之间的网络，可放心传文件'
- Relay fallback: orange ⚠ banner: '中继模式 — 视频/控制走服务器 21117 中转，请勿传大文件'
The banner is reactive (Obx on ConnectionType.direct Rx<String>).
3. flutter/lib/common/widgets/toolbar.dart: wrap the 'Transfer file' and
'TCP tunneling' menu items' onPressed with an isDirectConnection() guard.
On relay mode, the menu still shows but the click is intercepted with a
toast explaining why the action is blocked.
4. flutter/lib/desktop/pages/remote_page.dart: add the banner via
Positioned(top: 0, left: 0, right: 0) at the end of bodyWidget's Stack.
Why this matters: user has 4 users on 5 Mbps server (114.55.133.123).
When NAT punch fails and the session goes through relay, file transfers
would saturate the server bandwidth. Showing the relay state + blocking
the file-transfer menu protects the server without requiring the user
to remember the technical detail.
- Added flutter/macos/Runner/custom.txt with default-settings.enable-audio=N
- Added custom.txt to Xcode Copy Bundle Resources (PBXResourcesBuildPhase)
- RustDesk's load_custom_client() reads this file and injects into DEFAULT_SETTINGS
- Users can still toggle 'Enable audio' in Settings; this just flips the default
This addresses the user's request to disable all 4 audio behaviors by default
(play remote sound, hear remote mic, voice call, capture host audio), all of
which share the single 'enable-audio' option.
