A simple yet powerful client-server system for controlling home appliances, built in C with support for both IPv4 and IPv6 connections.

• Dual Stack Support: Works with both IPv4 and IPv6 connections
• Multi-threading: Efficient server handling with separate threads for:
  • Client requests
  • File handling
  • Automated backups
• Device Control: Currently supports:
  • Light switches (On/Off)
  • Boiler control (On/Off)
• State Persistence: Maintains device states across restarts
• Activity Logging: Comprehensive logging system with:
  • Command history
  • State changes
  • Error tracking
• Automated Backups: Daily backups of all system logs and states

• GCC Compiler
• POSIX-compliant system (Linux/Unix)
• pthread library
• Basic network connectivity

1. Clone the repository:

git clone https://github.com/rudokir/hac.git
cd hac

2. Build the project:

chmod +x build.sh
./build.sh

./Server

Connect to localhost (default):

./User

Connect to specific host:

./User hostname

Connect and send command:

./User hostname command

• Client Request Handler: Manages incoming connections and command processing
• File Handler: Handles state persistence and logging
• Backup System: Performs daily backups at 3:00 AM
