Cockpit is a lightweight, web-based server management tool. It provides an intuitive dashboard to monitor system performance, manage services, troubleshoot issues, and much more.

Firewalld is a dynamic firewall management tool with support for network zones. It allows for on-the-fly changes to your firewall rules without disrupting ongoing connections.

Run the following commands to ensure your system is updated:

sudo dnf update -y  # For RHEL-based systems

sudo dnf install cockpit -y  # RHEL/CentOS

sudo apt install cockpit -y  # Ubuntu/Debian

sudo systemctl enable --now cockpit.socket

sudo firewall-cmd --add-service=cockpit --permanent

sudo dnf install firewalld -y  # RHEL/CentOS

sudo apt install firewalld -y  # Ubuntu/Debian

Open a browser and navigate to https://<your-server-ip>:9090.
