🚀 Getting Started & Fixing Issues

Essential Command Cheat Sheet

Common Fixes

1. Permission Denied: Use ls -l to check ownership. Fix with sudo chown user:group [file] or chmod 644 [file].

2. Full Disk Issues: Run du -sh /* to find large directories. Clean logs with journalctl --vacuum-time=3d.

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

🧰 The Expert’s Toolbox

To resolve issues, I utilize industry-standard tools:

• Performance: htop, iostat, netstat, vmstat.

• Networking: nmap, tcpdump, dig, iperf3.

• Security: Lynis (auditing), Fail2Ban, ClamAV.

• Containerization: Docker, Podman, kubectl.

💡 Tips for a Successful Server Setup

• Minimize the Footprint: Install only necessary packages to reduce the attack surface.

• Always Use Key-Based Auth: Disable password authentication in /etc/ssh/sshd_config.

• Partition Wisely: Separate /var, /home, and / to prevent system crashes during log overflows.

• Document Everything: Use Version Control (Git) for your configuration files.
