Mark Sobell’s A Practical Guide to Ubuntu Linux®, Fourth Edition, is the most thorough and up-to-date reference to installing, configuring, securing, and working with Ubuntu desktops and servers.

This edition has been fully updated for Ubuntu 14.04 (Trusty Tahr), a milestone LTS (Long Term Support) release, which Canonical will support on both desktops and servers into 2019.

Sobell walks you through every essential feature and technique, from installing Ubuntu to working with the latest Ubuntu Unity desktop, and from configuring servers and monitoring networks to handling day-to-day system administration. His exceptionally clear explanations demystify everything from Apache, Samba, and postfix, to ufw, virtualization, and MariaDB/MySQL database management. PLUS a new chapter on programming in Python, today’s most popular system automation tool!

Fully updated JumpStart sections quickly help you get complex servers running–often in minutes. You’ll also find up-to-date guidance on new LPI and CompTIA Linux certification pathways for Linux professionals.

Sobell draws on his immense Linux knowledge to explain both the “hows” and the “whys” of Ubuntu. He’s taught hundreds of thousands of readers and never forgets what it’s like to be new to Linux. Whether you’re a user, administrator, or programmer, you’ll find everything you need here–now, and for years to come.

The world’s most practical Ubuntu Linux book is now even more useful!
