System Administration (LTAT.06.003) Lecture 1 Introduction

Syllabus Attendance to labs is not mandatory. All information will be either in Courses and/or Moodle. Every week there will be a new practical lab. In the end of the course, there will be an exam. All labs have to be completed before you are allowed to the exam. Labs: 50% of your final grade Exam: 50% of your final grade Course is graded positively if you collect at least 51% of total points

Syllabus Labs do not have an intermediate deadline. Labs have to be done and presented at least a week before the exam. Hopefully there will be an automatic grading server for the labs, to make solving them easier. Labs will be available here: https://courses.cs.ut.ee/2019/sa/spring/Main/Labs The exam will consist of the same materials you will do in the labs. You will be given a broken Linux installation with some non-functioning services, and your job will be to fix the machine.
