   277→## Update: 23:15 (Continued Session - Major Agent Features)
   278→
   279→### Work Completed
   280→
   281→1. **Support Code to Session Linking**
   282→   - Agent extracts 6-digit code from executable filename (e.g., `GuruConnect-123456.exe`)
   283→   - Server links support codes to WebSocket sessions
   284→   - Dashboard auto-refreshes every 3 seconds to show connected clients
   285→   - Client machine name displayed when connected
   286→
   287→2. **Cancellation Flow Implementation**

   289→   - Server: Periodic cancellation check every 2 seconds during active session
   290→   - Server: Rejects connections with already-cancelled codes
   291→   - Agent: Handles Disconnect message with "cancelled" reason
   292→   - Agent: Shows Windows MessageBox notification to user
   293→   - Agent: Exits cleanly without reconnecting for support sessions
   294→
   295→3. **System Tray Icon**

   297→   - Menu shows: Session code, Machine name, "End Session"
   298→   - Windows message queue pumping for event handling
   299→   - Clicking "End Session" cleanly terminates the agent
   300→
   301→4. **UAC Elevation Support**
   302→   - Windows manifest requesting `highestAvailable` privileges
   303→   - Embedded via winres crate in build.rs
   304→   - `is_elevated()` function to detect admin status
   305→   - Logs elevation status on startup
   306→
   307→5. **Startup Persistence**
   308→   - Agent adds itself to `HKCU\Software\Microsoft\Windows\CurrentVersion\Run`
   309→   - Persists through reboots until session ends
   310→   - Removed from startup on session end (cancel, user exit, or completion)
   311→
   312→6. **Chat System (In Progress)**
   313→   - Added ChatMessage to protobuf (id, sender, content, timestamp)
   314→   - Server relays chat between agent and viewer
   315→   - Agent chat module created (shows messages via MessageBox)
   316→   - Chat controller with command/message channels

   339→fn extract_code_from_filename() -> Option<String> {
   340→    let exe_path = std::env::current_exe().ok()?;
   341→    let filename = exe_path.file_stem()?.to_str()?;
   342→    for part in filename.split(|c| c == '-' || c == '_' || c == '.') {
   343→        if part.len() == 6 && part.chars().all(|c| c.is_ascii_digit()) {
   344→            return Some(part.to_string());
   345→        }

   357→        while PeekMessageW(&mut msg, None, 0, 0, PM_REMOVE).as_bool() {
   358→            let _ = TranslateMessage(&msg);
   359→            DispatchMessageW(&msg);
   360→        }
   361→    }
   362→}
   363→```
   364→
   365→#### Cancellation Check Loop (server/src/relay/mod.rs)

   370→        interval.tick().await;
   371→        if support_codes_check.is_cancelled(&code).await {
   372→            // Send disconnect message and close connection
   373→        }
   374→    }

   402→
   403→### Server Deployment Notes
   404→
   405→**Important:** After server changes, deploy with:
   406→```bash
   407→ssh guru@172.16.3.30 "kill \$(pgrep -f guruconnect-server); sleep 2"
   408→ssh guru@172.16.3.30 "rm -f ~/guru-connect/target/release/guruconnect-server"
   409→ssh guru@172.16.3.30 "cp ~/guru-connect/target/x86_64-unknown-linux-gnu/release/guruconnect-server ~/guru-connect/target/release/"
   410→ssh guru@172.16.3.30 "cd ~/guru-connect && nohup ./target/release/guruconnect-server > server.log 2>&1 &"
   411→```
   412→
   413→The systemd service path was incorrect - server expects to be run from `~/guru-connect` directory for static file serving.
   414→
   415→### Current Agent Binary Location
   416→- Windows: `C:\Users\MikeSwanson\Claude\guru-connect\target\x86_64-pc-windows-msvc\release\guruconnect-agent.exe`
   417→- For distribution: Copy to `guru@172.16.3.30:~/guru-connect/server/static/GuruConnect.exe`
   418→
   419→---

   436→   - Agent: `startup::uninstall()` removes from startup registry and schedules exe deletion
   437→   - Dashboard: Red "Disconnect" button in Access tab machine details
   438→   - Confirmation dialog before disconnecting
   439→
   440→3. **Fixed Static File Serving**

   607→## Update: 00:15 (Persistence & Hidden Console)
   608→
   609→### Work Completed
   610→
   611→1. **Fixed Persistence Logic**
   612→   - Persistent agents (no code) now ALWAYS add to startup registry
   613→   - Support sessions only temporarily in startup while active
   614→   - Persistent agents automatically reconnect on any disconnect (5 second delay)
   615→   - Support sessions exit without reconnecting
   616→
   617→2. **Restricted Session Termination**
   618→   - Persistent agents: No "End Session" menu item, shows "Managed by Administrator" (disabled)
   619→   - Persistent agents can ONLY be removed via admin Disconnect button in dashboard
   620→   - Support sessions: User can still end via tray icon "End Session"
   621→
   622→3. **Hidden Console Window**
   623→   - Added `#![windows_subsystem = "windows"]` for release builds - no console window
   624→   - Agent runs silently with only tray icon visible
   625→   - Added "Show Debug Window" menu item to tray
   626→   - Uses AllocConsole() to show console on demand for troubleshooting
   627→
   628→### Files Modified
   629→
   630→- `agent/src/main.rs` - windows_subsystem, show_debug_console(), persistence logic fixes
   631→- `agent/src/session/mod.rs` - show_debug_console(), handle ShowDebugWindow action
   632→- `agent/src/tray/mod.rs` - Added debug_item, allow_end_session parameter
   633→- `agent/Cargo.toml` - Added Win32_System_Console feature
   634→
   635→### Key Code Changes
   636→
   637→#### Hidden Console (main.rs)
   638→```rust
   639→// Hide console window by default on Windows (release builds)
   640→#![cfg_attr(not(debug_assertions), windows_subsystem = "windows")]
   641→```
   642→
   643→#### Persistence Logic Fix (main.rs)
   644→```rust
   645→// Add to startup so we reconnect after reboot
   646→// Persistent agents (no code) should ALWAYS be in startup
   647→if let Err(e) = startup::add_to_startup() {
   648→    warn!("Failed to add to startup");
   649→}
   650→
   651→// Only support sessions can be ended by user
   652→let tray = tray::TrayController::new(&hostname, support_code.as_deref(), is_support_session);
   653→```
   654→
   655→#### Tray Menu (tray/mod.rs)
   656→```rust
   657→// Only show "End Session" for support sessions
   658→let end_session_item = if allow_end_session {
   659→    MenuItem::new("End Session", true, None)
   660→} else {
   661→    MenuItem::new("Managed by Administrator", false, None)
   662→};
   663→
   664→// Debug window option (always available)
   665→let debug_item = MenuItem::new("Show Debug Window", true, None);
   666→```
   667→
   668→### Git Commits This Update
   669→```
   670→52c47b2 Fix persistence logic for persistent vs support sessions
   671→d7c272d Restrict session termination to support sessions only
   672→5bb5116 Hide console window, add Debug Window tray option
   673→```
   674→
   675→### Agent Behavior Summary
   676→
   677→| Feature | Persistent Agent | Support Session |
   678→|---------|-----------------|-----------------|
   679→| Startup registry | Always added | Added while active |
   680→| End Session menu | Disabled | Enabled |
   681→| Reconnect on disconnect | Yes (5 sec) | No |
   682→| Removal method | Admin only | User or cancel |
   683→| Console window | Hidden | Hidden |
   684→| Debug window | Available | Available |
   685→
   686→### Connection Behavior
   687→- Agents maintain **persistent WebSocket connection** (not polling)
   688→- Video frames sent at **30 FPS** (configurable, only when changes)
   689→- No explicit heartbeat mechanism currently
   690→- If disconnected, persistent agents retry every **5 seconds**
   691→- Server immediately knows when agent disconnects (WebSocket close)

### Cargo Config (.cargo/config.toml on build server)
```toml
[target.x86_64-pc-windows-gnu]
linker = "x86_64-w64-mingw32-gcc"
ar = "x86_64-w64-mingw32-ar"

[target.i686-pc-windows-gnu]
linker = "i686-w64-mingw32-gcc"
ar = "i686-w64-mingw32-ar"

[alias]
win64 = "build --release --target x86_64-pc-windows-gnu"
linux = "build --release --target x86_64-unknown-linux-gnu"
```

---

## Commands Reference

### Build Commands
```bash
# Build Linux server
cargo build -p guruconnect-server --release --target x86_64-unknown-linux-gnu

# Cross-compile Windows agent
cargo build -p guruconnect-agent --release --target x86_64-pc-windows-gnu
```

### Start Server
```bash
cd ~/guruconnect-server
RUST_LOG=info nohup ./guruconnect-server > guruconnect.log 2>&1 &
```

### Check Server Status
```bash
ps aux | grep guruconnect-server
cat ~/guruconnect-server/guruconnect.log

---

## Problems Encountered & Solutions

### 1. Windows Crate 0.58 Breaking Changes
- **Problem:** Many API changes from earlier versions
- **Solution:** Updated all affected files to match new API signatures

### 2. Tracing Macro Variable Collision
- **Problem:** Variable named `display` conflicted with tracing's `display` function
- **Solution:** Renamed variables to `target_display` or `primary_display`

### 3. Borrow Checker Issues
- **Problem:** Holding mutable borrow across async boundaries
- **Solution:** Restructured code to release borrows before calling methods on self

### 4. No Sudo Access on Build Server
- **Problem:** Couldn't install to /opt or create systemd service
- **Solution:** Deployed to home directory, running as user process

---

## Pending Tasks

1. **Server Persistence** - Currently running via nohup, will stop on reboot
   - Options: crontab @reboot, user systemd service, or get sudo access

2. **Test Agent on Windows** - Download and run agent to test full flow

3. **Authentication** - Currently using placeholder "dev-key" for API auth

4. **Integration with GuruRMM** - Dashboard components ready but not integrated

---

   - Agent extracts 6-digit code from executable filename (e.g., `GuruConnect-123456.exe`)
   - Server links support codes to WebSocket sessions
   - Dashboard auto-refreshes every 3 seconds to show connected clients
   - Client machine name displayed when connected

2. **Cancellation Flow Implementation**
   - Server: Cancelling a code (even if connected) sends Disconnect message to agent
   - Server: Periodic cancellation check every 2 seconds during active session
   - Server: Rejects connections with already-cancelled codes
   - Agent: Handles Disconnect message with "cancelled" reason
   - Agent: Shows Windows MessageBox notification to user
   - Agent: Exits cleanly without reconnecting for support sessions

3. **System Tray Icon**
   - Green circle tray icon when connected
   - Menu shows: Session code, Machine name, "End Session"
   - Windows message queue pumping for event handling
   - Clicking "End Session" cleanly terminates the agent

4. **UAC Elevation Support**
   - Windows manifest requesting `highestAvailable` privileges
   - Embedded via winres crate in build.rs
   - `is_elevated()` function to detect admin status
   - Logs elevation status on startup

5. **Startup Persistence**
   - Agent adds itself to `HKCU\Software\Microsoft\Windows\CurrentVersion\Run`
   - Persists through reboots until session ends
   - Removed from startup on session end (cancel, user exit, or completion)

6. **Chat System (In Progress)**
   - Added ChatMessage to protobuf (id, sender, content, timestamp)
   - Server relays chat between agent and viewer
   - Agent chat module created (shows messages via MessageBox)
   - Chat controller with command/message channels

fn extract_code_from_filename() -> Option<String> {
    let exe_path = std::env::current_exe().ok()?;
    let filename = exe_path.file_stem()?.to_str()?;
    for part in filename.split(|c| c == '-' || c == '_' || c == '.') {

```

#### Windows Message Pumping (agent/src/tray/mod.rs)
```rust
#[cfg(windows)]
fn pump_windows_messages() {
    unsafe {
        let mut msg = MSG::default();
        while PeekMessageW(&mut msg, None, 0, 0, PM_REMOVE).as_bool() {
            let _ = TranslateMessage(&msg);
            DispatchMessageW(&msg);
        }
    }
}
```

#### Cancellation Check Loop (server/src/relay/mod.rs)
```rust
let cancel_check = tokio::spawn(async move {
    let mut interval = tokio::time::interval(Duration::from_secs(2));
    loop {
        interval.tick().await;
        if support_codes_check.is_cancelled(&code).await {
            // Send disconnect message and close connection
        }

### Server Deployment Notes

**Important:** After server changes, deploy with:
```bash
ssh guru@172.16.3.30 "kill \$(pgrep -f guruconnect-server); sleep 2"
ssh guru@172.16.3.30 "rm -f ~/guru-connect/target/release/guruconnect-server"
ssh guru@172.16.3.30 "cp ~/guru-connect/target/x86_64-unknown-linux-gnu/release/guruconnect-server ~/guru-connect/target/release/"
ssh guru@172.16.3.30 "cd ~/guru-connect && nohup ./target/release/guruconnect-server > server.log 2>&1 &"
```

The systemd service path was incorrect - server expects to be run from `~/guru-connect` directory for static file serving.

### Current Agent Binary Location
- Windows: `C:\Users\MikeSwanson\Claude\guru-connect\target\x86_64-pc-windows-msvc\release\guruconnect-agent.exe`
- For distribution: Copy to `guru@172.16.3.30:~/guru-connect/server/static/GuruConnect.exe`

        let disconnect_msg = proto::Message {
            payload: Some(proto::message::Payload::Disconnect(proto::Disconnect {
                reason: reason.to_string(),
            })),
        };
        // Send via input channel to agent

## Update: 00:15 (Persistence & Hidden Console)

### Work Completed

1. **Fixed Persistence Logic**
   - Persistent agents (no code) now ALWAYS add to startup registry
   - Support sessions only temporarily in startup while active
   - Persistent agents automatically reconnect on any disconnect (5 second delay)
   - Support sessions exit without reconnecting

2. **Restricted Session Termination**
   - Persistent agents: No "End Session" menu item, shows "Managed by Administrator" (disabled)
   - Persistent agents can ONLY be removed via admin Disconnect button in dashboard
   - Support sessions: User can still end via tray icon "End Session"

3. **Hidden Console Window**
   - Added `#![windows_subsystem = "windows"]` for release builds - no console window
   - Agent runs silently with only tray icon visible
   - Added "Show Debug Window" menu item to tray
   - Uses AllocConsole() to show console on demand for troubleshooting

### Files Modified

- `agent/src/main.rs` - windows_subsystem, show_debug_console(), persistence logic fixes
- `agent/src/session/mod.rs` - show_debug_console(), handle ShowDebugWindow action
- `agent/src/tray/mod.rs` - Added debug_item, allow_end_session parameter
- `agent/Cargo.toml` - Added Win32_System_Console feature

### Key Code Changes

#### Hidden Console (main.rs)
```rust
// Hide console window by default on Windows (release builds)
#![cfg_attr(not(debug_assertions), windows_subsystem = "windows")]
```

#### Persistence Logic Fix (main.rs)
```rust
// Add to startup so we reconnect after reboot
// Persistent agents (no code) should ALWAYS be in startup
if let Err(e) = startup::add_to_startup() {
    warn!("Failed to add to startup");
}

// Only support sessions can be ended by user
let tray = tray::TrayController::new(&hostname, support_code.as_deref(), is_support_session);
```

#### Tray Menu (tray/mod.rs)
```rust
// Only show "End Session" for support sessions
let end_session_item = if allow_end_session {
    MenuItem::new("End Session", true, None)
} else {
    MenuItem::new("Managed by Administrator", false, None)
};

// Debug window option (always available)
let debug_item = MenuItem::new("Show Debug Window", true, None);
```

### Agent Behavior Summary

| Feature | Persistent Agent | Support Session |
|---------|-----------------|-----------------|
| Startup registry | Always added | Added while active |
| End Session menu | Disabled | Enabled |
| Reconnect on disconnect | Yes (5 sec) | No |
| Removal method | Admin only | User or cancel |
| Console window | Hidden | Hidden |
| Debug window | Available | Available |

### Connection Behavior

My concern is both zombie sessions as well as what time of performance/bandwidth will be used if I have 2000 machines connected?


The user is asking about two concerns:
1. Zombie sessions - connections that appear alive but are actually dead
2. Scalability - what happens with 2000 persistent agent connections

Let me think through both:

**Zombie Sessions:**
Currently, the agent maintains a persistent WebSocket connection. If the connection drops cleanly, the server knows immediately. But if a connection becomes a "zombie" (network issue, agent frozen, etc.), the server might not know.

Solutions:
- Heartbeat/ping-pong mechanism
- TCP keepalive (may already be handled by tokio-tungstenite)
- Application-level heartbeats

**Scalability with 2000 machines:**

Current design:
- Each agent has a persistent WebSocket connection
- Video frames sent at 30 FPS... but wait, that's only when a viewer is connected and watching!
- When idle (no viewer), what happens?

Looking at the code:
- The agent's `run()` loop captures and sends frames continuously
- This is wasteful if no one is viewing

Actually, let me reconsider. Looking at the session flow:
1. Agent connects via WebSocket
2. Agent immediately starts capturing and sending frames
3. Server relays to any connected viewer

This means even idle agents are:
- Capturing screen at 30 FPS
- Encoding frames
- Sending compressed data over WebSocket

With 2000 machines, this is extremely problematic:
- CPU usage on each agent (constant capture/encode)
- Bandwidth: Even with compression and dirty-rect, maybe 10-50 KB/frame when changes occur
- Server would be overwhelmed receiving 2000 streams

The proper architecture should be:
1. Agent connects and stays idle (just heartbeat)
2. When a viewer wants to connect, server tells agent to start streaming
3. Agent only captures/sends when being actively viewed
4. When viewer disconnects, agent goes back to idle

This is how ScreenConnect, TeamViewer, etc.

I'll outline a more efficient approach to manage remote access connections. The key is on-demand streaming, which dramatically reduces unnecessary resource consumption. By implementing a lazy initialization strategy, we can significantly improve system performance and scalability.


Great questions. Let me break down both concerns:

## Current Design Problems

**Zombie Sessions:**
- WebSocket close is detected immediately for clean disconnects
- But network issues (NAT timeout, frozen agent, etc.) can leave "zombie" connections
- No application-level heartbeat currently - relying only on TCP keepalive

**Bandwidth/Performance at Scale:**
Looking at the current code, there's a bigger issue - the agent starts streaming immediately upon connection:

```rust
// agent/src/session/mod.rs - runs continuously
loop {
    if last_frame_time.elapsed() >= frame_interval {
        if let Some(frame) = capturer.capture()? {  // Always capturing!
            let encoded = encoder.encode(&frame)?;
            transport.send(msg).await?;  // Always sending!
        }
    }
}
```

With 2000 agents all streaming at 30 FPS, even with compression:
- **Agent CPU:** Constant screen capture and encoding (wasted when no viewer)
- **Agent bandwidth:** 10-100 KB/sec per agent even when idle
- **Server:** 2000 incoming streams = impossible to handle

## Proper Architecture

The agent should have two modes:

| Mode | Activity | Bandwidth |
|------|----------|-----------|
| **Idle** | Heartbeat only (every 30-60 sec) | ~100 bytes/min |
| **Active** | Streaming to viewer | 100 KB-2 MB/sec |

**Flow:**
1. Agent connects → sends registration → enters **idle mode**
2. Server stores connection, responds to heartbeats
3. Technician clicks "Connect" → server sends `StartStream` command
4. Agent enters **active mode** → starts capturing/sending
5. Viewer disconnects → server sends `StopStream` command
6. Agent returns to **idle mode**

This is how ScreenConnect, TeamViewer, and RustDesk all work.

## Estimated Resource Usage (2000 agents, proper design)

| Metric | Idle | 10 Active Sessions |
|--------|------|-------------------|
| Server connections | 2000 WebSockets | 2000 + 10 viewers |
| Server bandwidth in | ~3 KB/sec (heartbeats) | ~10 MB/sec |
| Server memory | ~50 MB | ~100 MB |
| Agent CPU | Near zero | 5-15% (capturing) |

Would you like me to implement this idle/active mode architecture? It would involve:
1. Adding `StartStream`/`StopStream` messages to the protocol
2. Agent state machine (idle vs streaming)
3. Server-side viewer routing (only relay when viewer connected)
4. Heartbeat mechanism with timeout detection


yes, implement idle/active mode


The user wants me to implement idle/active mode for the GuruConnect agent. This is a significant architectural change that will involve:

1. Protocol changes - add StartStream/StopStream messages, Heartbeat with proper ack
2. Agent changes - state machine for idle vs active mode
3. Server changes - track agent state, route viewer connections, send start/stop commands

Let me plan this out and then implement it. I should use the TodoWrite tool to track this work.

Let me start by reading the current protocol definition and understanding the full scope of changes needed.

Good, I can see the proto file already has Heartbeat and HeartbeatAck messages. I need to add:
1. StartStream message - server tells agent to start streaming
2. StopStream message - server tells agent to stop streaming
3. AgentStatus message - agent sends periodic status updates when idle

Let me update the proto file first, then move on to updating the agent and server.


Good, the proto already has Heartbeat/HeartbeatAck. I need to add StartStream/StopStream messages. Let me update the protocol:

Good, now I need to add these new messages to the Message wrapper's oneof payload.


Now add them to the Message wrapper:

Protocol updated. Now I need to update the agent to implement the idle/active state machine. Let me read the current session/mod.rs to understand the structure better, then rewrite it with proper state management.

The key changes for the agent:
1. Add AgentState enum (Idle, Streaming)
2. When connecting, enter Idle mode - only send heartbeats and handle messages
3. When StartStream received, enter Streaming mode - capture and send frames
4. When StopStream received, return to Idle mode
5. Send AgentStatus periodically when idle
6. Handle heartbeats properly (respond to server heartbeats, send our own)

Let me look at the current session structure first.


Now let me update the agent's session module to implement idle/active mode. First, let me see the full structure:
