Students attending the course obtain hands-on experience with modern Linux systems. The course starts from the process of selecting a Linux distribution suitable for a certain planned scenario of its usage. Students can choose their distribution freely, and they use it during the entire course. Distributions chosen by the students are installed into a virtual environment that is used in the course without a risk of causing potential problems on a standard network. Students obtain deeper knowledge in two main areas, namely, storage subsystems and server-side services, as well as in various subsystems closely related to these main main topics of the course. The part of course devoted to storage includes different views on Linux file systems, logical volume management, and encryption of individual partitions. The course also covers server-side data storage technologies such as software RAID and export of block devices using the iSCSI standard. The part of the course devoted to server-side services concentrates on high-availability and load-balancing clusters and their impact on services provided by a system. Further, the course also contains an introduction to the SELinux security project as well as to network management in Linux.
