M FeilnerMarkus Feilner is a seasoned Linux expert from Regensburg, Germany. He has been working with free and open source software since 1994, as a trainer, consultant, author and journalist. His first contact with UNIX was a SUN cluster and SPARC workstatios at Regensburg University (during his studies of geography). Since 2000, he has published many books and courses used in Linux training sessions all over the world. Among that were three books for Packt (two on OpenVPN and one on Scalix Groupware). In the same year, he founded his own Linux consulting and training company, Feilner IT. He was also working as a trainer, consultant, and systems engineer at Millenux, Munich, where he focused on groupware, collaboration, and virtualization with Linux-based systems and networks. Until 2015, he had been deputy editor-in-chief at the German Linux-Magazine, where he wrote about open source software for both printed and online magazines, including the Linux Technical Review and the Linux Magazine International (the U.S., UK, and Australia). Today, the Conch diplomat, Minister of the Universal Life Church, Jedi Knight, and owner of lunar property holds several nationalities and is employed as Team Lead of the SUSE Documentation Team in Nrnberg. He regularly gives keynotes, workshops, lectures, and presentations at tech and political conferences in Germany. He is interested in anything about geography, traveling, photography, philosophy (especially that of open source software), global politics, modern science, arts and literature, but always has too little time for these hobbies.
