  1100→### Work Completed
  1101→
  1102→#### 1. Online/Offline Session Tracking
  1103→**Problem:** Laptop agent disappeared from session list when machine went to sleep.
  1104→
  1105→**Solution:** Implemented `is_online` and `is_persistent` flags:
  1106→- **Persistent agents** (no support code) stay in session list when disconnected, marked "Offline"
  1107→- **Support sessions** (with code) are removed entirely on disconnect
  1108→- Agent reconnection reuses existing session
  1109→- Dashboard shows green dot for online, gray for offline
  1110→- Connect/Chat buttons disabled when agent is offline
  1111→
  1112→**Files Modified:**
  1113→- `server/src/session/mod.rs` - Added is_online, is_persistent, viewers tracking
  1114→- `server/src/relay/mod.rs` - Pass is_persistent to register_agent, use mark_agent_disconnected
  1115→- `server/src/api/mod.rs` - Added is_online, is_persistent, viewers to API response
  1116→- `server/static/dashboard.html` - Online/offline status, clickable filters
  1117→
  1118→#### 2. Dashboard Filter Feature
  1119→- "Online" and "Offline" sidebar items are now clickable
  1120→- Filters machine list to show only online or offline machines
  1121→- Counts update correctly based on is_online status
  1122→
  1123→#### 3. Fail2ban Lockout Fix (CRITICAL)
  1124→**Problem:** Build server (172.16.3.30) SSH was completely locked due to:
  1125→1. Multiple failed auth attempts triggered fail2ban
  1126→2. SSH hardening.conf had `PasswordAuthentication no`

## Update: 01:36 (Online/Offline Sessions & Fail2ban Fix)

### Session Summary

Major session addressing offline agent persistence, fail2ban lockout, and dashboard enhancements.

### Work Completed

#### 1. Online/Offline Session Tracking
**Problem:** Laptop agent disappeared from session list when machine went to sleep.

**Solution:** Implemented `is_online` and `is_persistent` flags:
- **Persistent agents** (no support code) stay in session list when disconnected, marked "Offline"
- **Support sessions** (with code) are removed entirely on disconnect
- Agent reconnection reuses existing session
- Dashboard shows green dot for online, gray for offline
- Connect/Chat buttons disabled when agent is offline

**Files Modified:**
- `server/src/session/mod.rs` - Added is_online, is_persistent, viewers tracking
- `server/src/relay/mod.rs` - Pass is_persistent to register_agent, use mark_agent_disconnected
- `server/src/api/mod.rs` - Added is_online, is_persistent, viewers to API response
- `server/static/dashboard.html` - Online/offline status, clickable filters

#### 2. Dashboard Filter Feature
- "Online" and "Offline" sidebar items are now clickable
- Filters machine list to show only online or offline machines
- Counts update correctly based on is_online status

#### 3. Fail2ban Lockout Fix (CRITICAL)
**Problem:** Build server (172.16.3.30) SSH was completely locked due to:
1. Multiple failed auth attempts triggered fail2ban
2. SSH hardening.conf had `PasswordAuthentication no`

**Solution (via VM disk mount from Jupiter):**
```bash
# On Jupiter (172.16.3.20):
virsh shutdown GuruRMM
qemu-nbd --connect=/dev/nbd0 -f raw /mnt/cache/domains/GuruRMM/vdisk1.img
vgchange -ay ubuntu-vg

EOF

# Unmount and start VM
umount /tmp/vm_mount
vgchange -an ubuntu-vg

```

**Result:** SSH key-based auth now works from Windows machine to build server.

#### 4. Connected Technician Tracking (In Progress)
**Feature Request:** Show connected technician names on machine bar (e.g., "Mike Connected (3 min)")

**Implementation Status:**
- ✅ ViewerInfo struct with id, name, connected_at

[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"
```

## 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

## Update: 23:15 (Continued Session - Major Agent Features)

### Work Completed

1. **Support Code to Session Linking**
   - 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

### Files Created/Modified

#### New Files

### Key Code Sections

#### Filename Code Extraction (agent/src/main.rs)
```rust
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 == '.') {
        if part.len() == 6 && part.chars().all(|c| c.is_ascii_digit()) {
            return Some(part.to_string());
        }
    }
    None
}
```

#### 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
        }
    }
});
```

3. **Test Full Flow**
   - Test chat with connected agent
   - Verify all features work together

### 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`

```rust
pub fn uninstall() -> Result<()> {
    // Remove from startup registry
    let _ = remove_from_startup();

    // Schedule exe for deletion on reboot
    let exe_path = std::env::current_exe()?;
    unsafe {
        MoveFileExW(
            PCWSTR(exe_wide.as_ptr()),
            PCWSTR::null(),
            MOVEFILE_DELAY_UNTIL_REBOOT,
        );
    }
    Ok(())
}
```

    if let Some(session_data) = sessions.get(&session_id) {
        let disconnect_msg = proto::Message {
            payload: Some(proto::message::Payload::Disconnect(proto::Disconnect {
                reason: reason.to_string(),
            })),
        };
        // Send via input channel to agent
        session_data.input_tx.send(buf).await.is_ok()
    }
}
```

#### Chat Protobuf Encoding (dashboard.html)
```javascript
function encodeChatMessage(msg) {
    // ChatMessage: id(1), sender(2), content(3), timestamp(4)
    // Wrapped in Message with payload field 60
    const fieldTag = (60 << 3) | 2;
    wrapper.push((fieldTag & 0x7f) | 0x80);

2. **File Transfer** - Transfer Files button is disabled
3. **Proper Authentication** - Still using placeholder "dev-key"
4. **Video Streaming** - Agent captures screen but viewer doesn't display yet
5. **Chat Reply from Client** - Client can only receive messages (no UI to reply)

---

## 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);
```

### Git Commits This Update
```
52c47b2 Fix persistence logic for persistent vs support sessions
d7c272d Restrict session termination to support sessions only
5bb5116 Hide console window, add Debug Window tray option
```

### 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
- Agents maintain **persistent WebSocket connection** (not polling)
- Video frames sent at **30 FPS** (configurable, only when changes)
- No explicit heartbeat mechanism currently
- If disconnected, persistent agents retry every **5 seconds**
- Server immediately knows when agent disconnects (WebSocket close)

## Update: 00:45 (Idle/Active Mode & Viewer Implementation)

### Session Summary

This session implemented two major features for GuruConnect:

1. **Idle/Active Mode** - Agents now connect in idle mode and only start streaming when a viewer connects. This allows thousands of agents to be connected with minimal bandwidth.

2. **Remote Desktop Viewer** - Full canvas-based viewer that displays video frames from agents and sends mouse/keyboard input.

### Work Completed

#### 1. Idle/Active Mode for Scalable Connections

**Problem:** Original design had agents streaming video immediately upon connection. With 2000 agents, this would be impossible to handle.

**Solution:** Implemented idle/active state machine:
- Agent connects → enters **idle mode** (heartbeat every 30s, status every 60s)
- Viewer connects → server sends `StartStream` → agent enters **streaming mode**
- Viewer disconnects → server sends `StopStream` → agent returns to **idle mode**
- Resources (capturer, encoder) only allocated when streaming

**Protocol Changes (proto/guruconnect.proto):**
```protobuf
message StartStream {
    string viewer_id = 1;
    int32 display_id = 2;
}

message StopStream {
    string viewer_id = 1;
}

message AgentStatus {
    string hostname = 1;
    string os_version = 2;
    bool is_elevated = 3;
    int64 uptime_secs = 4;
    int32 display_count = 5;
    bool is_streaming = 6;
}
```

**Bandwidth Comparison (2000 agents):**
| Metric | Before | After |
|--------|--------|-------|
| Agent bandwidth (idle) | 100+ KB/sec | ~100 bytes/min |
| Server incoming | Impossible | ~3 KB/sec heartbeats |
| CPU per agent (idle) | 5-15% | Near 0% |

#### 2. Remote Desktop Viewer

Created full-featured viewer at `server/static/viewer.html`:
- Canvas-based video display
- Protobuf parsing for VideoFrame/RawFrame
- Zstd decompression using fzstd library
- BGRA to RGBA conversion for canvas
- Mouse event capture (move, click, wheel)
- Keyboard event capture
- Ctrl+Alt+Del special key support
- Fullscreen toggle
- Auto-reconnect on connection loss
- FPS/resolution stats display

**Dashboard Integration:**
- `joinSession()` now opens viewer in new window
- `connectToMachine()` now opens viewer in new window

### Files Created/Modified

#### New Files
- `server/static/viewer.html` - Full viewer implementation (684 lines)

#### Modified Files
- `proto/guruconnect.proto` - Added StartStream, StopStream, AgentStatus messages
- `agent/src/session/mod.rs` - Idle/active state machine, lazy resource allocation
- `agent/src/main.rs` - Pass is_elevated to SessionManager
- `server/src/session/mod.rs` - Viewer tracking, start/stop stream, heartbeat timeout
- `server/src/relay/mod.rs` - Handle AgentStatus, Heartbeat messages
- `server/src/api/mod.rs` - Added is_streaming, last_heartbeat, etc. to API response
- `server/static/dashboard.html` - Open viewer instead of alert

### Key Code Sections

#### Agent State Machine (agent/src/session/mod.rs)
```rust
enum SessionState {
    Disconnected,
    Connecting,
    Idle,       // Connected but not streaming
    Streaming,  // Actively capturing and sending frames
}

// Only allocate resources when streaming
fn init_streaming(&mut self) -> Result<()> {
    let capturer = capture::create_capturer(...);
    let encoder = encoder::create_encoder(...);
    let input = InputController::new()?;
    // ...
}

fn release_streaming(&mut self) {
    self.capturer = None;
    self.encoder = None;
    self.input = None;
}
```

#### Server Viewer Tracking (server/src/session/mod.rs)
```rust
pub async fn join_session(&self, session_id: SessionId, viewer_id: ViewerId) {
    let was_empty = session_data.viewers.is_empty();
    session_data.viewers.insert(viewer_id.clone());

    // If first viewer, send StartStream to agent
    if was_empty {
        Self::send_start_stream_internal(session_data, &viewer_id).await;
    }
}

pub async fn leave_session(&self, session_id: SessionId, viewer_id: &ViewerId) {
    session_data.viewers.remove(viewer_id);

    // If no more viewers, send StopStream
    if session_data.viewers.is_empty() {
        Self::send_stop_stream_internal(session_data, viewer_id).await;
    }
}
```

#### Viewer Protobuf Parsing (viewer.html)
```javascript
function parseVideoFrame(data) {
    // Parse Message wrapper → VideoFrame → RawFrame
    // Extract width, height, compressed data
    return { width, height, compressedData, isKeyframe };
}

function renderFrame(frame) {
    const decompressed = fzstd.decompress(frame.compressedData);
    // Convert BGRA to RGBA
    for (let i = 0; i < decompressed.length; i += 4) {
        pixels[i] = decompressed[i + 2];     // R <- B
        pixels[i + 2] = decompressed[i];     // B <- R
    }
    ctx.putImageData(imageData, 0, 0);
}
```

```

### Testing Performed

**Agent ACG-TECH-01L connected and tested:**
```
00:28:52 - Agent connected (idle mode)
00:28:52 - Agent status: streaming=false, uptime=0s
00:29:13 - Viewer joined → StartStream sent
00:29:16 - Chat test sent
00:29:20 - Viewer disconnected → StopStream sent
00:29:52 - Agent status: streaming=false, uptime=60s
```

All transitions working correctly:
- ✓ Agent starts in idle mode
- ✓ StartStream sent when viewer connects
- ✓ StopStream sent when viewer disconnects
- ✓ Agent returns to idle mode

+## Update: 01:36 (Online/Offline Sessions & Fail2ban Fix)

+Major session addressing offline agent persistence, fail2ban lockout, and dashboard enhancements.

+#### 1. Online/Offline Session Tracking

+**Problem:** Laptop agent disappeared from session list when machine went to sleep.

+**Solution:** Implemented `is_online` and `is_persistent` flags:

+- **Persistent agents** (no support code) stay in session list when disconnected, marked "Offline"

+- **Support sessions** (with code) are removed entirely on disconnect

+- Agent reconnection reuses existing session

+- Dashboard shows green dot for online, gray for offline

+- Connect/Chat buttons disabled when agent is offline

+- `server/src/session/mod.rs` - Added is_online, is_persistent, viewers tracking

+- `server/src/relay/mod.rs` - Pass is_persistent to register_agent, use mark_agent_disconnected

+- `server/src/api/mod.rs` - Added is_online, is_persistent, viewers to API response

+- `server/static/dashboard.html` - Online/offline status, clickable filters

+- "Online" and "Offline" sidebar items are now clickable

+- Filters machine list to show only online or offline machines

+- Counts update correctly based on is_online status

+#### 3. Fail2ban Lockout Fix (CRITICAL)

+**Problem:** Build server (172.16.3.30) SSH was completely locked due to:

+1. Multiple failed auth attempts triggered fail2ban

+2. SSH hardening.conf had `PasswordAuthentication no`

+**Solution (via VM disk mount from Jupiter):**

+qemu-nbd --connect=/dev/nbd0 -f raw /mnt/cache/domains/GuruRMM/vdisk1.img

+# Fix fail2ban - whitelist internal networks

+cat > /tmp/vm_mount/etc/fail2ban/jail.local << 'EOF'

+cat > /tmp/vm_mount/etc/ssh/sshd_config.d/hardening.conf << 'EOF'

+cat >> /tmp/vm_mount/home/guru/.ssh/authorized_keys << 'EOF'

+**Result:** SSH key-based auth now works from Windows machine to build server.

+#### 4. Connected Technician Tracking (In Progress)

+**Feature Request:** Show connected technician names on machine bar (e.g., "Mike Connected (3 min)")

+- ✅ ViewerInfo struct with id, name, connected_at

+- ✅ Server tracks viewer names (join_session accepts viewer_name)

+- ✅ API returns viewers list with each session

+- 🔄 Viewer HTML update pending (pass viewer_name param)

+- `server/src/session/mod.rs` - ViewerInfo struct, HashMap for viewers, updated join/leave

+- `server/src/relay/mod.rs` - ViewerParams now has viewer_name, passed to join_session

+- `server/src/api/mod.rs` - ViewerInfoApi struct, viewers in SessionInfo

+1cc94c6 Add is_online/is_persistent for persistent agent sessions

+d01fb41 Fix sidebar counts to use is_online status

+f3b76b7 Add clickable Online/Offline filters in sidebar

+[uncommitted] Technician tracking implementation

+#### Fail2ban Configuration (172.16.3.30)

+- 100.64.0.0/10 (Tailscale CGNAT range)

+Now in `/home/guru/.ssh/authorized_keys` - enables passwordless SSH from Windows.

+- **SSH:** Key-based auth now works from Windows (claude-code key)

+- **SSH via plink:** `plink -batch guru@172.16.3.30 -pw "Gptf*77ttb123!@#-rmm" "command"`

+- **SSH via plink:** `plink -batch root@172.16.3.20 -pw "Th1nk3r^99##" "command"`

+- **GuruRMM VM:** Running, contains build server at 172.16.3.30

+- **External URL:** https://connect.azcomputerguru.com

+- **Running from:** ~/guru-connect/target/release/guruconnect-server

+ssh -o BatchMode=yes guru@172.16.3.30 "command"

+plink -batch guru@172.16.3.30 -pw "Gptf*77ttb123!@#-rmm" "command"

+ssh -o BatchMode=yes guru@172.16.3.30 "

+cargo build -p guruconnect-server --release --target x86_64-unknown-linux-gnu

+cp -r server/static/* ~/guru-connect/server/static/

+cd ~/guru-connect && nohup ./target/release/guruconnect-server > /tmp/guruconnect.log 2>&1 &

+scp -o BatchMode=yes server/static/dashboard.html guru@172.16.3.30:~/guru-connect/server/static/

+   - Update dashboard.html to show connected technicians on machine bar

+   - Update viewer.html to pass viewer_name parameter

+   - Build server code complete, just needs frontend

+2. **Session Keepalive Feature** (user requested)

+   - Prevent machine from sleeping when technician is connected

+3. **Screen Distortion** (user reported)

+   - Distortion at top of screen during remote session

+   - Need to investigate frame alignment

+4. **File Transfer** - Transfer Files button disabled

+5. **Proper Authentication** - Replace "dev-key" placeholder

+1. ACG-TECH-01L connected as persistent agent

+2. Laptop went to sleep → showed "Offline" in dashboard (gray dot)

+3. Sidebar counts updated to "Online: 0, Offline: 1"

+4. Laptop woke → reconnected to same session

+5. Dashboard showed "Online" again (green dot)

+6. Sidebar counts updated to "Online: 1, Offline: 0"

+- Click "Online" → shows only online machines

+- Click "Offline" → shows only offline machines

+- Click "All Machines" → shows all machines


Conversation compacted


This session is being continued from a previous conversation that ran out of context. The conversation is summarized below:
Analysis:
Let me chronologically analyze this conversation:

1. **Initial Context Recovery**: The conversation began with a summary from a previous session about GuruConnect - a remote desktop solution. Key work included idle/active mode, viewer implementation, and session tracking.

2. **User's First Request**: "That laptop was asleep, and disappeard from sessions. It should have remained in sessionlist but show as offline when sleeping?"
   - This was about implementing is_online/is_persistent flags for sessions
   - I had already started this work (Session struct had new fields) before the context recovery

3. **Online/Offline Implementation**:
   - Updated `mark_agent_disconnected` to keep persistent sessions but mark offline
   - Updated `relay/mod.rs` to pass is_persistent and use mark_agent_disconnected
   - Updated API to include is_online field
   - Updated dashboard to show online/offline status with colors

4. **Deployment Issues - Fail2ban Lockout**:
   - SSH to build server (172.16.3.30) started failing with "Too many authentication failures"
   - User clarified: "Jupiter is the host where the build server lives" and "Build server is 3.30"
   - Jupiter (172.16.3.20) hosts the GuruRMM VM which runs at 172.16.3.30
   - Had to mount VM disk from Jupiter to fix both fail2ban config AND sshd hardening.conf

5. **User's Feedback on Online/Offline**:
   - "Machine is asleep, shows offline in portal, but is still in online header" - sidebar counts were wrong
   - Fixed by using proper is_online filtering in counts

6. **User's Request for Clickable Filters**:
   - "Should the headers 'Online' 'Offline' also be clickable? Like to filter for either"
   - Implemented filter functionality with click handlers

7. **User's Request for Technician Tracking**:
   - "when a technician is connected, on the right of that bar can it say 'Mike Connected' and if Howard and I (or any other technician) are connected it would say 'Howard, Mike Connected (3 min)'"
   - Started implementing ViewerInfo tracking in server
   - Added ViewerInfo struct with id, name, connected_at
   - Updated join_session to accept viewer_name parameter
   - Updated API to return viewers list
   - Server builds successfully

8. **User Request to Save Session**: "/s"
   - User asked to save session log, I wrote comprehensive update to session log

9. **Additional User Requests Throughout**:
   - "btw: add optional session keepalive. (When technician is connected, there should be an option to prevent the machine from sleeping)"
   - "Also set exception for my IP address or for this machine if necessary"
   - "Also set exception for my IP address or for this machine if necessary. Set exceptions for any internal connection, Jupiter/my machine/etc."
   - "With that being said I don't want a hack attempt to take the entire system down"
   - "There is a fair amount of 'distortion' at the top of the screen (remote session)"

Key files modified:
- server/src/session/mod.rs - ViewerInfo, is_online, is_persistent, viewers HashMap
- server/src/relay/mod.rs - viewer_name parameter, is_persistent
- server/src/api/mod.rs - ViewerInfoApi, viewers in response
- server/static/dashboard.html - online/offline status, clickable filters

Current work: Technician tracking feature - server-side complete, dashboard/viewer UI pending

Summary:
1. Primary Request and Intent:
   - **Offline Session Persistence**: User wanted laptop agents to remain in session list when machine sleeps, showing as "Offline" instead of disappearing
   - **Clickable Filters**: User wanted Online/Offline sidebar items to be clickable to filter the machine list
   - **Connected Technician Display**: User requested showing connected technician names on machine bar: "when a technician is connected, on the right of that bar can it say 'Mike Connected' and if Howard and I (or any other technician) are connected it would say 'Howard, Mike Connected (3 min)'"
   - **Fail2ban Configuration**: User wanted internal IPs whitelisted so internal connections don't get blocked
   - **Session Keepalive**: User mentioned "add optional session keepalive. (When technician is connected, there should be an option to prevent the machine from sleeping)"
   - **Screen Distortion**: User reported "There is a fair amount of 'distortion' at the top of the screen (remote session)"

2. Key Technical Concepts:
   - Session state tracking (is_online, is_persistent flags)
   - Persistent vs support sessions (persistent = no support code)
   - Viewer/technician tracking with ViewerInfo struct
   - Fail2ban configuration and whitelisting
   - VM disk mounting via qemu-nbd and LVM for emergency SSH access
   - SSH hardening configuration (PasswordAuthentication)
   - Dashboard filtering with JavaScript

3. Files and Code Sections:
   - **server/src/session/mod.rs** - Core session management with viewer tracking
     - Added ViewerInfo struct for tracking connected technicians
     - Changed viewers from HashSet to HashMap<ViewerId, ViewerInfo>
     - Updated Session struct with viewers: Vec<ViewerInfo>
     ```rust
     /// Information about a connected viewer/technician
     #[derive(Debug, Clone)]
     pub struct ViewerInfo {
         pub id: ViewerId,
         pub name: String,
         pub connected_at: chrono::DateTime<chrono::Utc>,
     }
     ```
     - Updated join_session signature:
     ```rust
     pub async fn join_session(&self, session_id: SessionId, viewer_id: ViewerId, viewer_name: String) -> Option<(FrameReceiver, InputSender)>
     ```
     - Updated mark_agent_disconnected to keep persistent sessions offline:
     ```rust
     pub async fn mark_agent_disconnected(&self, session_id: SessionId) {
         if session_data.info.is_persistent {
             session_data.info.is_online = false;
             session_data.info.is_streaming = false;
             session_data.info.viewer_count = 0;
             session_data.info.viewers.clear();
             session_data.viewers.clear();
         } else {
             // Support session - remove entirely
         }
     }
     ```

   - **server/src/relay/mod.rs** - WebSocket handler updates
     - Added viewer_name to ViewerParams:
     ```rust
     #[derive(Debug, Deserialize)]
     pub struct ViewerParams {
         session_id: String,
         #[serde(default = "default_viewer_name")]
         viewer_name: String,
     }

     fn default_viewer_name() -> String {
         "Technician".to_string()
     }
     ```
     - Updated handle_viewer_connection to accept and pass viewer_name

   - **server/src/api/mod.rs** - API response with viewer info
     ```rust
     #[derive(Debug, Serialize)]
     pub struct ViewerInfoApi {
         pub id: String,
         pub name: String,
         pub connected_at: String,
     }

     pub struct SessionInfo {
         // ... other fields ...
         pub viewers: Vec<ViewerInfoApi>,
     }
     ```

   - **server/static/dashboard.html** - Dashboard UI updates
     - Fixed sidebar counts to use is_online:
     ```javascript
     const onlineCount = machines.filter(m => m.is_online).length;
     const offlineCount = machines.filter(m => !m.is_online).length;
     ```
     - Added clickable filter handlers:
     ```javascript
     let currentFilter = 'all';
     document.querySelectorAll('.sidebar-item[data-filter]').forEach(item => {
         item.addEventListener('click', () => {
             currentFilter = item.dataset.filter;
             document.querySelectorAll('.sidebar-item[data-filter]').forEach(i => i.classList.remove('active'));
             item.classList.add('active');
             renderMachinesList();
         });
     });
     ```
     - Updated renderMachinesList to filter:
     ```javascript
     let filteredMachines = machines;
     if (currentFilter === 'online') {
         filteredMachines = machines.filter(m => m.is_online);
     } else if (currentFilter === 'offline') {
         filteredMachines = machines.filter(m => !m.is_online);
     }
     ```

4. Errors and Fixes:
   - **SSH Connection Refused to Build Server (172.16.3.30)**:
     - Cause: Too many failed auth attempts triggered fail2ban, AND hardening.conf had `PasswordAuthentication no`
     - Fix: Mounted VM disk from Jupiter, edited fail2ban jail.local to whitelist internal networks, edited hardening.conf to enable PasswordAuthentication, cleared fail2ban database, added SSH key
     - User feedback: "Make sure you didn't lock yourself out of the build server, use RMM agent if needed"
     - User clarification: "I need you to permanently untangle Jupiter from the Build Server in your brain. Jupiter is the host where the build server lives."

   - **Sidebar Counts Wrong**:
     - User: "Machine is asleep, shows offline in portal, but is still in online header"
     - Cause: Counts were hardcoded to show all machines as online
     - Fix: Changed to use `machines.filter(m => m.is_online).length`

5. Problem Solving:
   - **Fail2ban Lockout Recovery**: Solved by shutting down VM, mounting disk via qemu-nbd and LVM, editing config files directly, then restarting
   - **Offline Session Persistence**: Implemented is_online/is_persistent flags with mark_agent_disconnected that preserves persistent sessions
   - **Dashboard Filtering**: Added currentFilter state variable and click handlers for sidebar items

6. All User Messages:
   - "That laptop was asleep, and disappeard from sessions. It should have remained in sessionlist but show as offline when sleeping?"
   - "Make sure you didn't lock yourself out of the build server, use RMM agent if needed."
   - "I need you to permanently untangle Jupiter from the Build Server in your brain. Jupiter is the host where the build server lives."
   - "Build server is 3.30"
   - "Guruconnect is deployed on the build server"
   - "Also set exception for my IP address or for this machine if necessary."
   - "Also set exception for my IP address or for this machine if necessary. Set exceptions for any internal connection, Jupiter/my machine/etc. I suppose we should still block the gateway on fail2ban. Open to suggestions"
   - "With that being said I don't want a hack attempt to take the entire system down, so I hope fail2ban or whatever mechanism we're using blocks extern sources, rather than internal"
   - "btw: add optional session keepalive. (When technician is connected, there should be an option to prevent the machine from sleeping)"
   - "There is a fair amount of 'distortion' at the top of the screen (remote session)"
   - "Machine is asleep, shows offline in portal, but is still in online header" (with screenshot)
   - "Should the headers 'Online' 'Offline' also be clickable? Like to filter for either"
   - "Wake works! Now on the bar for the machine - when a technician is connected, on the right of that bar can it say 'Mike Connected' and if Howard and I (or any other technician) are connected it would say 'Howard, Mike Connected (3 min)' or some variation on that?"
   - "/s" (save session)

7. Pending Tasks:
   - **Complete Technician Tracking UI** - Server code complete, need dashboard and viewer updates
   - **Session Keepalive Feature** - Prevent machine sleep when technician connected
   - **Screen Distortion Investigation** - User reported distortion at top of screen
   - **File Transfer** - Transfer Files button disabled
   - **Proper Authentication** - Replace "dev-key" placeholder

8. Current Work:
   Implementing connected technician display feature. Server-side code is complete:
   - ViewerInfo struct created with id, name, connected_at
   - join_session accepts viewer_name parameter
   - API returns viewers list
   - Server builds successfully

   Was about to update dashboard.html to display connected technicians on the machine bar, and update viewer.html to pass viewer_name parameter when connecting.

9. Optional Next Step:
   Continue with technician tracking UI implementation:
   1. Update dashboard.html machine bar to show connected technicians: "Mike Connected (3 min)"
   2. Update viewer.html to pass viewer_name parameter in WebSocket URL
   3. Deploy updated server and static files

   Direct quote from user's request: "when a technician is connected, on the right of that bar can it say 'Mike Connected' and if Howard and I (or any other technician) are connected it would say 'Howard, Mike Connected (3 min)' or some variation on that?".
Please continue the conversation from where we left it off without asking the user any further questions. Continue with the last task that you were asked to work on.


Looking at the context, I was in the middle of implementing the connected technician display feature. The server-side code is complete:
- ViewerInfo struct added
- join_session accepts viewer_name
- API returns viewers list
- Server builds successfully

The pending work is:
1. Update dashboard.html to show connected technicians on the machine bar
2. Update viewer.html to pass viewer_name parameter when connecting
3. Deploy updated server and static files

Let me continue with updating the dashboard.html to display connected technicians. I need to read the current dashboard.html to see the machine bar structure and add the viewer display.


I'll continue with the technician tracking UI implementation. The server-side is complete, now I need to update the dashboard to display connected technicians on the machine bar.

Add ViewerInfo struct with name and connected_at

Update join_session to accept viewer name

Update API to return viewer list

Update dashboard to show connected technicians on machine bar

Update viewer.html to pass viewer_name parameter

Deploy updated server and static files


Good, I've read the dashboard. Now I need to update the machine list rendering to show connected technicians. The user wants to show something like "Mike Connected (3 min)" on the right of the machine bar when technicians are connected.

Looking at the current code, the machine cards are rendered in `renderMachinesList()` function around line 695. I need to:

1. Add viewer info display to the machine bar
2. Calculate the time duration since connection
3. Format names like "Mike, Howard Connected (3 min)"

The API response now includes `viewers` array with `{id, name, connected_at}` for each viewer.

Let me update the `renderMachinesList` function to include the technician display.


Now I'll update the `renderMachinesList` function to display connected technicians on the machine bar. I need to add a helper function for time formatting and update the machine card rendering.
