An Introduction to Sysadmin Training in the Virtual Unix Lab

The Virtual Unix Lab (vulab) is an interactive course system which allows students to do Unix system administration exercises. Machines are installed on which students can do their assignments with full ”root”-access. At the end, the system checks which parts were done correctly, and gives a feedback on the exercise result. Access to the lab is via the Internet via a web-browser as well as standard Unix clients (ssh, telnet, ftp). Some detail on exercise-verification are outlined in this paper.
