Objective : To give the student sufficient theoretical and practical understanding and knowledge to design and implement a small TCP/IP local network connected to the Internet using PCs running Linux as the platform for both workstations and servers.
Principal Content : Workstation installation - turning your laptop into a working Linux computer

Unix usage: Users; file systems and their structure; essential commands. Graphical desktops.

Networks: Linux in a networking environment: Structure and configuration of the networking software.

Building your own system: Installing packages: "make", "RPM" and "tar". The Kernel and how to build it.

Basic security: threats, prevention, detection.

Servers: Choosing your type of servers (file, mail, print, name, web, DHCP, Samba, database); Building and securing the chosen server.
Teaching method : 50% of the time will be used by lectures and discussions, which will cover the theoretical aspects.

The practical part will fall in two parts: workstation installation and set-up will be done individually whereas server building will be done as a couse assignment in groups of up to four students.

The course will conclude with the handing-in of a report on the course assignment.
Required prequisites : Knowledge corresponding to the contents of NET4/NETE.
Recommended prerequisites : The Network Management course NETM.
Relations : None
Type of examination : Oral examination based on assignments
External examiner : Internal
Marking : Scale of 13
Remarks : The examination is a group examination but the marking is individual.

At the examination each student is allocated 15 minutes.

The evaluation is based on a general impression of the level achieved by the student relative to the objective of the course. The evaluation is based on the report, the oral performance and the functionality of the project.

The group presents the project by giving well-prepared presentations. The duration of the presentation is approx. 5 minutes. The group is required to coordinate the presentations in such a way that the major aspects of the project are covered, that the presentations are different and that each individual presentation has a good technical span.

After the presentation the supervisors and the external examiner pose questions inspired by the presentations, the report and the curriculum in general. The questions are a priori individual but may - if found relevant by the supervisors or the external examiner - form the basis of a broader group discussion.

During the evaluation by the supervisors and the external examiner, the project group leaves the room. Afterwards the group is summoned and the individual marks are explained.

If a student doesn"t pass the examination, the student is given guidance on how to improve the chances of passing.
