📖 Starting with Linux Commands

To navigate these different distributions effectively, I recommend mastering the primary package managers and core system commands.

1. Package Management (The Distro "Translator")

2. Essential System Health Commands

• top or htop: Check real-time CPU and Memory usage.

• df -h: View disk space in human-readable format.

• journalctl -xe: View the most recent system error logs.

• ip a: Check your network interface and IP addresses.

3. Fixing Common Issues 🔧

• Permission Denied: Use ls -l to check ownership. Fix with sudo chown user:group [file] or sudo chmod 755 [file].

• SSH Connection Refused: Check if the service is running with sudo systemctl status ssh. Ensure port 22 is open in your firewall.

• Disk Full: Run du -sh /* to find which directory is consuming space. Clear logs in /var/log or temp files in /tmp.

💡 Tips for a Successful Server Setup

I recommend following these four pillars for every new installation:

1. Minimal Installation: Only install the packages you need. This reduces the attack surface and saves resources.

2. SSH Key Authentication: Disable password logins for SSH immediately. Use SSH keys for much higher security.

3. Automatic Security Updates: Enable "unattended upgrades" to ensure critical security patches are applied even when you aren't watching.

4. Baseline Documentation: Always document your custom configurations in a central "Runbook" so recovery is seamless.
