Good, the pull was successful. Now let me build the server on Linux.


Bash

ssh guru@172.16.3.30 "cd ~/guru-connect && cargo build -p guruconnect-server --release --target x86_64-unknown-linux-gnu 2>&1 | tail -25"

Build server on Linux


bash: line 1: cargo: command not found


The cargo command isn't in the path. Let me source the cargo environment first.


ssh guru@172.16.3.30 "source ~/.cargo/env && cd ~/guru-connect && cargo build -p guruconnect-server --release --target x86_64-unknown-linux-gnu 2>&1 | tail -30"

Build server on Linux with cargo env

All three endpoints work:
1. Viewer download - 7429120 bytes, filename "GuruConnect-Viewer.exe"
2. Support download - 7429120 bytes (same as base), filename "GuruConnect-123456.exe"
3. Agent download - 7429251 bytes (131 bytes larger due to embedded config!), filename "GuruConnect-TestCorp-HQ-Setup.exe"

The agent download is larger because it has the embedded config appended. Let me verify the magic bytes are correctly embedded by downloading a sample and checking.


All endpoints working. The agent download is 131 bytes larger due to embedded config (magic bytes). Let me verify the embedded config is correct:


curl -s "https://connect.azcomputerguru.com/api/download/agent?company=TestCorp&site=HQ&tags=windows,workstation" -o /c/tmp/test-agent.exe && tail -c 200 /c/tmp/test-agent.exe | xxd | tail -15

Download and inspect embedded config

The embedded config is working. I can see:
1. The magic marker "GURUCONFIG"
2. The length bytes (0x96 0x00 0x00 0x00 = 150 in little-endian)
3. The JSON config: `{"server_url":"wss://connect.azcomputerguru.com/ws/agent","api_key":"managed-agent","company":"TestCorp","site":"HQ","tags":["windows","workstation"]}`

The deployment system is now fully working. Let me update the todo list to mark everything complete and provide a summary.


The embedded config is working correctly. I can see:
- Magic marker: `GURUCONFIG`

- JSON config with server_url, api_key, company, site, and tags

All tasks are complete. Let me provide a summary of what was accomplished.


The magic bytes deployment system is now fully implemented and deployed. Here's a summary:

## Completed Implementation

### Agent Mode Detection
The agent now detects its run mode based on filename:
- **GuruConnect-Viewer.exe** → Viewer mode (protocol handler only)
- **GuruConnect-123456.exe** → Temp support session (6-digit code)
- **GuruConnect-Setup.exe** with embedded config → Permanent agent

### Download Endpoints
Three new API endpoints generate configured binaries:

| Endpoint | Result |
|----------|--------|
| `/api/download/viewer` | GuruConnect-Viewer.exe (base binary) |
| `/api/download/support?code=123456` | GuruConnect-123456.exe (code in filename) |
| `/api/download/agent?company=X&site=Y&tags=a,b` | GuruConnect-X-Y-Setup.exe (embedded config) |

### Dashboard UI
The Build tab now has:
- **Quick Downloads**: Viewer download and temp support agent generator
- **Permanent Agent Builder**: Form to configure company/site/tags and download

### Embedded Config Format
```
[PE Binary][GURUCONFIG][length:u32 LE][JSON config]
```

Example embedded JSON:
```json
{"server_url":"wss://connect.azcomputerguru.com/ws/agent","api_key":"managed-agent","company":"TestCorp","site":"HQ","tags":["windows","workstation"]}
```

All endpoints are live at https://connect.azcomputerguru.com. End users can now download configured agents without needing command-line flags.
