👨‍💻 Getting Started & Fixing Issues

Every distribution family has its nuances. Here is my quick-reference guide for navigating different Linux environments.

Core Commands by Distribution

Fixing Common "Pain Points"

• Issue: Disk Space Full. * Fix: Use du -sh /* to find the culprit. Often, /var/log is filled with unrotated logs. Clear them with journalctl --vacuum-time=2d.

• Issue: SSH Connection Timed Out.

  • Fix: Check if the service is running (systemctl status sshd) and ensure the port is open in the firewall (ufw allow 22 or firewall-cmd --add-port=22/tcp --permanent).

• Issue: Dependency Hell.

  • Fix: On Debian-based systems, use sudo apt --fix-broken install. On RHEL systems, use dnf distro-sync.

🚀 Tips for a Successful Server Setup

1. Always Use Key-Based SSH: Disable password authentication immediately to prevent 99% of brute-force attacks.

2. Separate Partitions: Keep /var and /home on separate partitions. If a log file explodes, it won't crash the entire OS.

3. Implement Swap Wisely: Even with high RAM, a small swap file (1–2GB) helps the kernel manage memory pressure more gracefully.

4. Document Everything: Use a simple git repository to store your configuration files (/etc) so you can track changes over time.
