🚀  Getting Started & Fixing Issues

⌨️ Essential Commands Across Distributions

While most commands are universal, package management differs by "family."

🛠️ Common Fixes for Typical Issues

1. Permission Denied: Ensure your user is in the sudo or wheel group. Use ls -l to check ownership.

2. Full Disk Space: Use du -sh /* to find large directories. Clean logs with journalctl --vacuum-time=2d.

3. SSH Connection Refused: Check if the service is running (systemctl status sshd) and ensure Port 22 is open in the firewall.

💡 Tips for Successful Server Installation

• Use LVM (Logical Volume Management): Always partition with LVM to allow for easy disk resizing in the future.

• Minimal Install: Only install the packages you need. This reduces the attack surface and improves performance.

• SSH Key Authentication: Disable password-based logins immediately in favor of SSH keys for better security.

• Documentation: Maintain an "Operational Runbook" detailing every custom change made to the baseline OS.
