Once you have your OpenSUSE VPS deployed, the first step is to perform initial setup tasks:

  • Connect to Your VPS: Use SSH to connect. Command: ssh username@your_server_ip
  • Update System Packages: Always start with updating your system.

2. Configure Your Firewall

A firewall is critical for protecting your server from unauthorized access. Here’s how to set it up:

  • Configure Firewall Rules: Allow necessary services and block unwanted ones. 
    sudo firewall-cmd --permanent --add-service=http
