📖 Starting with Essential Commands

Depending on your distribution, the "gatekeeper" to your system is the package manager. Here is how to perform basic tasks across different flavors:

💡 Fixing Common Issues

1. Permission Denied: Always check ownership first: ls -l. Use chown -R user:group /path to fix.

2. Disk Space Full: Use du -sh /* | sort -h to find the culprit directory. Usually, it's /var/log.

3. SSH Connection Refused: Ensure the service is running (systemctl status ssh) and that port 22 is open in the firewall (ufw allow 22 or firewall-cmd --add-port=22/tcp).

✨ Tips for a Successful Server Setup

• Minimize the Install: Always start with a "Minimal Install" to reduce the attack surface. You can add what you need later.

• SSH Key Auth Only: Disable password authentication in /etc/ssh/sshd_config immediately.

• Separate Partitions: Place /var, /home, and /tmp on separate partitions to prevent a log overflow from crashing the entire system.

• Documentation: Keep a "Runbook" of every custom configuration change you make.
