📘 Command Essentials & Troubleshooting

1. Universal Package Management

Navigating different distros requires knowing your package manager:

• Ubuntu/Debian: sudo apt update && sudo apt upgrade

• RHEL/AlmaLinux: sudo dnf check-update && sudo dnf upgrade

• Arch: sudo pacman -Syu

2. Fixing Common Connectivity Issues

If your server isn't communicating, I recommend this flow:

• Check IP: ip addr show

• Check Routing: ip route

• Test DNS: dig google.com or nslookup

• Check Port Listening: ss -tulpn (Replaces the deprecated netstat)

3. Resolving Permission Denied Errors

Often, the issue is SELinux or Ownership:

• Check SELinux status: sestatus

• Fix ownership: chown -R user:group /path/to/directory

🧰 The Expert’s Toolkit

To resolve complex issues, I utilize a specialized stack of tools:

• Performance: htop, iotop, glances, and sar.

• Network: tcpdump, wireshark (tshark), nmap, and iperf.

• Storage: lsblk, fdisk, and smartctl for disk health.

• Debugging: strace (trace system calls) and gdb.

💡 Tips for a Successful Server Setup

1. Always use Key-Based Auth: Disable password authentication in /etc/ssh/sshd_config immediately.

2. Separate Partitions: Keep /var and /home on separate partitions to prevent system crashes if logs or user data fill the disk.

3. Document Everything: Maintain a "Runbook." If a manual change is made, script it or write it down.

4. Minimalism Wins: Only install the packages you need. A smaller footprint means a smaller attack surface.
