Curriculum

Aim:

During the course the students get acquainted with the installation, administration and security of Unix based operating systems. Apart from the basic questions of management, the security aspects of Unix systems and services are the core points of the course. The students get theoretical and practical knowledge on installation of multiple Unix based operating systems. Get to know methods of creating file systems and the theoretical background on how these file systems should be created and which file system should be used for a specific role on a live system. They also learn about user management, creating and administering groups, assigning users to groups and managing access rights both on the file system level and for the services. This part includes both the conventional access rights and the new role based access control available on modern systems. The students get a deep understanding of the BASH shell – from the basic commands to sophisticated shell scripts. They learn how to implement a network infrastructure necessary for hosting network services on the computer: network settings (static and dynamic IP settings), firewalls, general acquaintance with the system services in Unix (init daemon, SMF). After such a general overview, the users learn about each of the services in a greater depth: SSH daemon, web server (Apache, PHP, MySQL), FTP server. The course material includes installation, basic and advanced configuration and the security aspects as well.

The students learn the methods of creating and managing shared resources in a heterogeneous environment (Unix and Windows)

The course is based on Sun Solaris, Sun OpenSolaris, SuSE linux and Ubuntu linux. In order for the students to acquire confidence in the different flavors of Unix, all of these four system will be used during the course.

Topics:

Introduction to Unix based operating systems

The aim of operating systems, overview of different systems, their development

Installation of different Unix based operating systems in practice – partitioning the hard drive, installing the boot loader

Usage: basic commands, text editors, shell scripts

Installing programs to different Unix based systems – Installation with package manager: synaptic, apt-get, yast, pkg; installing from source: configure, makefile etc.

Starting the system, system services

Process of starting a Unix system (BIOSMBRboot loader  kernel  initshell)

GRUB setup, install, recovery

Run levels – defining services to run automatically

Making an own program start automatically upon boot

Overview /etc/init.d directory

Advanced service management in Solaris: SMF

File system management

How HDDs are built up, different labels (msdod, EFI), file system types (ext2, ext3, ext4, reiserfs) ordinary vs. journaling file systems

Theoretical background of partition management – how to partition the disks in a computer according to its role

Partitioning and file system creation in practice using multiple tools (fdisk, cfdisk, parted, gparted)

Mounting file systems manually (mount) and automatically (fstab)

Logical Volume Management overview, creating and managing volumes

RAID management – software RAID0, RAID1 implementation in linux

ZFS: introducing the pool based file system of the future (Solaris) – creating new pools and file systems, resizing, self healing file systems

User management, permissions

User management and permissions in Unix – introduction

Local login, /etc/passwd, /etc/group, /etc/shadow files

Creating users and groups – manually or automatically with console or GUI tools

Role Based Access Control in OpenSolaris – defining and managing roles

Permissions: file system protection, security of services, access control

Network settings

TCP/IP networking basics (review of what has been learned earlier)

Network settings in Unix based systems – adding network cards, static and dynamic IP addresses Binding network interfaces. Firewalls

Service management

Installing and setting an SSH daemon – security settings, ports, welcome messages. Key based authentication (ssh-agent)

Installing and setting up a www server – Apache, httpd.conf. Basic settings (port, server name, listening IP), advanced settings (custom error pages, virtual servers). Security settings. Optimization for high workloads. Modules, PHP

SQL server administration – working together with Apache. Creating and managing schemes and databases using phpMyAdmin

FTP server administration – installation, creating users. Access rights management. Setting shared directories, permission

Management in a heterogeneous environment

Interaction between Unix based and Windows clients. Remote desktop connection. Accessing Windows shares from Unix using Samba.

Sharing resources of a Unix machine (directories, printers)

Requirements

In order to be able to take the exam, the students need to achieve at least 51% on the exam at the end of the semester, and they also need to do an assignment.

Assignment

The students will develop an infrastructure of at least 3 (virtual) computers using different Unix based operating systems. Each of the computers have a dedicated role in the infrastructure – web server, database server, client. The infrastructure will host a web service (website, blog, forum etc. – one that can be downloaded from the internet)

Make up

• The students can take the exam again in the last week, they can also hand their assignments in.

Prerequisite for the exam: at least 51% on the final test and doing the homework assignment

Final grade: (Exam): mixed examination of theoretical and practical knowledge at the end of the semester
