Advance your expertise in SUSE Linux Enterprise Server 16 by exploring remote administration, network configuration, security hardening, and automation techniques. Learn to secure and streamline enterprise Linux operations with confidence. This course delves into advanced topics essential for managing SUSE Linux Enterprise Server 16 in complex environments. You will explore remote system administration, network configuration, firewall management, SELinux security, and automation with system roles. Learners will also gain experience with Cockpit for system monitoring and management, as well as container management using Podman. By completing this course, you will be equipped to secure, automate, and optimize SLES 16 systems for enterprise needs. The course uses practical examples and scenario-based instruction to help learners apply advanced networking, security, and automation concepts. Emphasis is placed on real-world workflows and best practices for robust and secure Linux administration. This course is part two of a three-course Specialization designed to build a complete and cohesive understanding of the subject. While it offers valuable skills on its own, you'll gain the most benefit by progressing through all three courses as a structured learning journey. This course is based on SUSE Linux Enterprise Server 16 Official Administration Guide, by Miguel Pérez Colino, Sergio Ocón Cárdenas and Pablo Iranzo Gómez.

Syllabus

Administering Systems Remotely
- This module introduces secure methods for remote system administration using SSH, including key-based authentication, file transfers with SCP, SFTP, and rsync, and advanced techniques like SSH tunnels and redirections. Learners will also explore the use of tmux for managing multiple remote terminal sessions efficiently. By the end, you'll be equipped to manage and automate remote systems securely and effectively.
Enabling and Using Cockpit
- This module introduces learners to Cockpit, a web-based interface for managing SUSE Linux Enterprise Server. Participants will learn how to install and access Cockpit, configure system settings such as storage, networking, and firewall, and manage user accounts and services through an intuitive UI. Additional tools for software management and system monitoring are also explored.
Securing Network Connectivity with firewalld
- This module guides learners through configuring and managing network security using firewalld, focusing on zones, ports, and service definitions. Participants will gain hands-on experience enabling firewalld, troubleshooting connectivity, and customizing service rules to strengthen system defenses.
Keeping the System Hardened with SELinux
- This module introduces Security-Enhanced Linux (SELinux) on SLES 16, focusing on its modes, policies, and essential management tools. Learners will explore how to review and modify SELinux contexts, adjust policies using semanage, and configure service permissions with Boolean settings. Practical examples and command-line techniques are provided to help maintain a secure and compliant system.
Agentic AI with mcphost
- This module introduces learners to agentic AI integration within SUSE Linux Enterprise Server 16 using the Model Context Protocol (MCP) and the mcphost tool. You will learn how to securely install, configure, and use mcphost to connect large language models, such as Google Gemini, while maintaining system security. Practical steps and best practices for setup and usage are covered throughout.
Manage Local Storage and Filesystems
- This module guides learners through the essentials of disk partitioning, filesystem formatting, and mounting in Linux environments. You will gain practical skills in configuring persistent storage using fstab and understand how to efficiently manage local storage resources. By the end, you'll be equipped to set up and maintain filesystems for reliable system operation.
Flexible Storage Management with LVM
- This module introduces learners to Logical Volume Management (LVM) in Linux, focusing on how to create, manage, and resize storage using physical volumes, volume groups, and logical volumes. You will gain practical skills in dynamically allocating disk space, combining storage devices, and safely removing storage components.
Configuring and Using System Snapshots with BTRFS and Snapper
- This module introduces the concepts and practical applications of filesystem-level snapshots using BTRFS and Snapper on SUSE Linux Enterprise Server. Learners will discover how snapshots enhance system resilience, enable configuration rollback, and facilitate change tracking through hands-on administration techniques.
Understanding the Boot Process
- This module guides learners through the critical stages of the Linux boot process, from hardware initialization to system startup. You will explore key components such as UEFI/BIOS, GRUB, initrd, and systemd, and gain practical skills in troubleshooting and system recovery, including password resets.
Automating with System Roles
- This module introduces the concept of system roles in SUSE Linux Enterprise Server and demonstrates how to automate system configuration using Ansible. Learners will gain practical skills in creating and applying Ansible playbooks to streamline administrative tasks and enhance system reliability.
Managing Containers with Podman
- This module introduces the fundamentals of container technology, focusing on Podman for container management and registry operations. Learners will gain practical skills in installing Podman, pulling images from registries, and troubleshooting running containers. The content emphasizes the significance of containers in modern DevOps and Kubernetes environments.
