The focus of the workshop "Campus Systems Linux Essentials" was to train Network/Systems engineers/operators of data networking (one who deals with the campus network) from LEARN member institutions to improve the use of Linux and its open-source tools for campus IT infrastructure. Linux, being free and open-source, is essential for running key applications like web servers, mail, identity management, and library systems.
