Summary

This unique, practical resource delivers specific Linux-based open source solutions to dozens of today's most common computing and business challenges. Each modular chapter covers all you need to know to solve a specific set of problems -- with extensive examples, and detailed guidance on acquiring and running the Linux-based open source software you'll need. Multitool Linux begins by reviewing the skills and mindset you need to make the most of Linux and open source software. The authors present comprehensive coverage of Linux as a solution for networking problems, covering remote control applications, routing, virtual private networks, file and print services for Windows clients, email, Web services, and more. The book covers a wide range of Linux-based security solutions, including secure logins, file transfers, email security, and encryption. The book also includes a full section on multimedia, ranging from video production to CD burning, 3D graphics to image processing. Each chapter includes pointers to URLs with the latest versions of every open source package covered in the book. For all Linux users and developers who want to use Linux to solve a wider variety of problems.
