Navigating different distributions requires understanding their unique package managers.
| Task | Debian/Ubuntu (APT) | RHEL/Rocky/Fedora (DNF) | Arch Linux (Pacman) |
| Update System | sudo apt update && upgrade | sudo dnf upgrade | sudo pacman -Syu |
| Install Package | sudo apt install [pkg] | sudo dnf install [pkg] | sudo pacman -S [pkg] |
| Check Services | systemctl status [svc] | systemctl status [svc] | systemctl status [svc] |
| Network Info | ip addr show | nmcli device show | ip link |
Permission Denied: Use ls -l to check ownership. Fix with sudo chown user:group [file] or chmod 644 [file].
Disk Full: Run df -h to find the partition and du -sh * to find the culprit folder.
Service Won't Start: Check the journal immediately: journalctl -u [service_name] -xe.
To resolve complex issues, I utilize industry-standard diagnostic tools:
Performance:htop, iotop, glances, and sar.
Networking:tcpdump, wireshark (for packet analysis), and netstat.
Storage:smartmontools for drive health and LVM for volume management.
Security:Lynis for security auditing and Fail2Ban for intrusion prevention.
Document Everything: Always maintain an updated "Runbook" for your server configurations.
Use Key-Based Auth: Disable password-based SSH login immediately to thwart 99% of brute-force attacks.
Minimize Packages: Only install what is necessary to reduce the attack surface.
Separate Partitions: Keep /home, /var, and / on separate partitions to prevent log files from crashing the OS.
