🐧 Supported Distributions

I provide expert-level support for all major Linux distributions, including:

👨‍💻 The Expert's Toolkit

To resolve complex issues, I utilize the industry’s most powerful diagnostic tools:

1. Performance: htop, iotop, sar, and glances for real-time resource tracking.

2. Networking: tcpdump, netstat, nmap, and dig for connectivity troubleshooting.

3. Logs: journalctl, tail -f, and ELK Stack for centralized logging.

4. Trace: strace and lsof to find exactly what a process is doing (or failing to do).

🚀  Getting Started & Fixing Issues

1. Essential Commands Across Distributions

While most commands are universal, package management differs. Here is how I handle them:

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

• RHEL/CentOS/Rocky: sudo dnf check-update && sudo dnf upgrade

• Arch Linux: sudo pacman -Syu

The "Golden" Troubleshooting Command:

# Check for failed services across any systemd-based distro
systemctl --failed

2. Fixing Common "Disk Full" Issues

If your server stops responding, it’s often a filled partition. I use this workflow:

1. Find the culprit: du -ah / | sort -rh | head -n 20

2. Clear logs: journalctl --vacuum-time=3d

3. Check for deleted but open files: lsof +L1

💡 Tips for a Successful Server Setup

• Principle of Least Privilege: Never log in as root directly. Use SSH keys and sudo.

• Document Everything: I maintain operational runbooks so you aren't left in the dark.

• Automate the Baseline: Use Ansible to ensure every new server has the same security patches and user configs from minute one.

• Separate Partitions: Always put /var/log and /home on separate partitions to prevent system crashes if logs or user data overflow.
