Device Management System Update - Version 2.4

Overview

This update adds remote command execution capabilities between the Server_Monitorizare and the prezenta devices, along with improved error handling for network connectivity issues.

New Features

1. Robust Network Configuration (app.py)

File-based fallback system: Device hostname and IP are saved to ./data/device_info.txt
Automatic error recovery: When socket.gaierror occurs, the system loads previously saved values
No external dependencies: Uses only built-in Python modules
Graceful degradation: App continues to run even with network issues

2. Remote Command Execution System

Server Side (server.py)

New endpoints added:

/device_management - Web interface for managing devices
/execute_command - Execute command on single device
/execute_command_bulk - Execute command on multiple devices
/device_status/<device_ip> - Get device status information

Device Side (app.py)

New Flask server running on port 5000:

/execute_command - Receive and execute system commands
/status - Provide device status information

3. Security Features

Whitelisted commands only: Prevents execution of arbitrary commands
Command logging: All command execution attempts are logged
Timeout protection: Commands have 5-minute timeout limit
Error handling: Comprehensive error reporting

4. Web Interface Improvements

Device Management Dashboard: Complete interface for managing all devices
Real-time status checking: Check if devices are online/offline
Bulk operations: Execute commands on multiple devices simultaneously
Search functionality: Filter devices by hostname or IP
Command selection: Dropdown menus for common system commands

Allowed Commands

For security, only these commands can be executed remotely:

sudo apt update - Update package lists
sudo apt upgrade -y - Upgrade packages
sudo apt autoremove -y - Remove unused packages
sudo apt autoclean - Clean package cache
sudo reboot - Reboot device
sudo shutdown -h now - Shutdown device
df -h - Check disk space
free -m - Check memory usage
uptime - Check system uptime
systemctl status - Check system services
sudo systemctl restart networking - Restart network services
sudo systemctl restart ssh - Restart SSH service

File Structure Changes

New Files:

Server_Monitorizare/templates/device_management.html - Device management interface
prezenta/data/device_info.txt - Device configuration cache (auto-created)

Modified Files:

prezenta/app.py - Added command execution server and network error handling
Server_Monitorizare/server.py - Added command execution endpoints
Server_Monitorizare/templates/dashboard.html - Added device management link

Usage Instructions

Starting the Services

Start the monitoring server (port 80):

cd Server_Monitorizare
sudo python3 server.py

Start the device app (ports 5000 for commands + normal operation):
```
cd prezenta
python3 app.py
```

Using the Web Interface

Navigate to http://server-ip:80/dashboard
Click "Device Management" to access the new interface
Use the dropdown menus to select commands
Execute on single devices or use bulk operations

Benefits

Centralized device management - Control all devices from one interface
Automated maintenance - Schedule updates and maintenance tasks
Real-time monitoring - Check device status and performance
Improved reliability - Network error handling prevents app crashes
Security - Controlled command execution with comprehensive logging
