This course is intended for students with a basic knowledge of Linux and its most common utilities and text editors. For users with no prior experience we suggest the free ‘Introduction to Linux’ course available on edx.org.

Perform essential Linux commands such as installation, searches and manipulating files. Operate running Linux systems by managing the boot process, scheduling jobs, updating the system, monitoring system performance and managing security. Manage users and groups by adding/deleting/modifying, configuring LDAP and PAM, modifying user processes and resources. Ensure network performance via configuration, monitoring, tunnelling and routing of traffic. Configure services such as DNS, shares, SSH and SELinux/AppArmor as well as servers for DHCP and HTTP. Manage system storage by using partitions, logical volumes, phsyical volumes, ACLs, quotas and clustering.
