📘 Navigating Major Distributions

If you are new to managing a multi-distro environment, I recommend mastering these package management commands first:

Common Fix: The "Full Disk" Crisis

If your server stops responding, check disk space: df -h. If /var/log is full, use sudo journalctl --vacuum-time=7d to clear old system logs safely.

🚀 Tips for a Successful Server Setup

1. Minimalism is Security: Never install a GUI on a production server. Install only the packages you absolutely need.

2. SSH Key-Only Auth: Disable password authentication in /etc/ssh/sshd_config immediately to stop 99% of brute-force attacks.

3. Use a Firewall from Day 1: Even if you think the server is "internal," enable ufw or firewalld.

4. Document via Code: Instead of manual tweaks, write an Ansible Playbook. This makes your server reproducible if it ever crashes.
