🛡️ GridAdmin - Local Network Administration System

GridAdmin is an advanced, multithreaded Client-Server application written in C, designed for the centralized administration of workstations within a local area network (LAN). It establishes a secure communication channel using a custom TCP protocol and features a graphical user interface (GUI) built with GTK+3.

• 🔒 Secure Communication: All TCP traffic between the client and server is encrypted using AES-256 (via OpenSSL).
• ⚡ Multithreaded Architecture: The server efficiently handles multiple concurrent client connections.
• 🖥️ Remote Shell Execution: Execute shell commands securely on remote workstations (SSH-like functionality).
• 🔌 Power Management: Features Wake-on-LAN (via UDP broadcasts) and remote shutdown capabilities.
• 📊 Live Monitoring: Real-time tracking of workstation status (Online/Offline) and network discovery using raw sockets.
• 🗄️ Data Persistence: Integrated SQLite for secure logging and data storage.

• Language: C
• Networking: TCP/UDP Sockets
• Cryptography: OpenSSL (AES-256)
• GUI: GTK+3
• Database: SQLite

The project includes an automated Makefile for easy compilation. Open a terminal in the project directory and run:

1. Install Dependencies:

make setup

2. Compile Server and Client:

make

3. Start the Server:

./server <num_threads> <encryption_key>

4. Start the Client:

./client <server_IP> <server_PORT> <server_encryption_key>

🔑 Default Credentials To access the administrative functions within the client GUI, use the following default credentials:

    user: admin
    password: adminpass
