$ Linux Administration

I manage and maintain Linux systems for web hosting, development, and security testing.
From server setup to automation and monitoring, I rely on Linux as the backbone of my infrastructure.

> Tools & Distros

• Distributions: Arch, Alpine, Debian, Rocky, Kali.
• Shell & Scripting: Bash, cron jobs, systemctl.
• Package Management: pacman, apk, apt, dnf, flatpack.
• Permission Management: groups, sudo, file permissions, ACLs.
• Networking: netstat/ss, ip, ufw, OpenSSH.
• Monitoring: top, journalctl, dmesg, system logs.

> Core Skills

1. System Setup & Configuration → Install and configure Linux servers (web, DB, DNS).
2. User Management → Creating users, setting permissions, and enforcing least privilege.
3. Service Management → Configuring Apache/Nginx, MariaDB, PHP, SSH.
4. Network Administration → Managing firewalls (ufw/iptables), VPNs, and SSH hardening.
5. Automation → Bash scripts for backups, updates, and log rotation.
6. Virtualization & Containers → Running VMs with KVM/QEMU and apps with Docker.
7. Maintenance & Updates → Regular patching, security updates, log review, and uptime monitoring.

> Hands-On Experience

• Personal home server running arch linux with docker containers for websites and bots.
• My daily driver distro is Lumo Linux a personalised version of Arch Linux made by me.
• Firewall management with ufw in both personal pc and server to secure the network.
• Custom script and programs for backups, server connections, updates and daily needs

> Best Practices

• Keeping systems updated and patched.
• Using SSH keys instead of passwords.
• Encrypting sensitive data and partitions.
• Regular backups (local + cloud).
• Monitoring logs for anomalies
