🚀 Essential Commands by Family

🔧 Fixing Common Linux Issues

1. "No Space Left on Device":

   • Fix: Run du -sh /* to find large directories. Clean logs with journalctl --vacuum-time=3d.

2. Service Fails to Start:

   • Fix: Check the specific error with journalctl -xeu [service_name].

3. SSH Connection Refused:

   • Fix: Verify the service is running (systemctl status sshd) and ensure the firewall allows port 22 (ufw allow 22).

💡 Tips for a Successful Server Setup

• Minimum Install: Always start with a "Minimal" or "Net-install" to reduce the attack surface.

• Separate Partitions: Keep /home, /var, and / on separate partitions to prevent log files from crashing the OS.

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

• Documentation: Always maintain a digital "Runbook" of every custom configuration change made to the server.
