Linux-Admin-Automamtion

Overview

This mini-project demonstrates essential skills in Linux administration, Git, Bash scripting, and networking. The goal is to create automation tools for managing a small Linux server environment, track changes using Git, and monitor system performance efficiently. it contains detailed documentations of whole process

Project Requirements

Part 1: Linux Server Administration

• Set up two Linux virtual machines:

• Admin Server (used for management)

• Target Server (to be managed)

• Configure SSH authentication with key-based login.

• Demonstrate:

• User Management (creating users, managing groups, permissions)

• Package Management (installing/configuring software)

• Service Management (configuring/enabling services)

• File System Management (partitioning, mounting, storage management)

• Process Management (monitoring and controlling processes)

Part 2: Networking Configuration

• Configure basic networking between the servers:

• Set up static IP addresses.

• Secure SSH authentication.

• Implement firewall rules using iptables or ufw.

• Set up a private network.

• Configure and test DNS resolution.

• Create a network documentation file with:

• Network topology diagram

• IP addressing scheme

• Firewall rule explanations

• Service ports in use

Part 3: Bash Automation Scripts

• system_inventory.sh - Collects system hardware info, installed packages, and running services.

• user_manager.sh - Manages users, groups, and SSH key authentication.

• system_hardening.sh - Secures SSH, disables unnecessary services, updates packages, and enforces security policies.

• network_monitor.sh - Monitors network connections, logs unusual activity, and reports bandwidth usage.

• backup_manager.sh - Automates backups, implements rotation policy, verifies integrity, and logs backup operations.

Part 4: Cron Jobs & Logging

• The cron jobs was set up to:

• Run system inventory weekly.

• Run network monitoring hourly.

• Perform daily backups.

• Check for system updates daily.

• centralized logging was implemented to:

• Configure log rotation.

• Add timestamps and appropriate log levels.

• Enable email notifications for critical events.

Setting up

1. clone the repository
