Basics of Linux system administration: Setting up your system and software 1. Before you begin You need a working Linux system that includes the bash shell, so you can practice the commands and techniques covered in this knowledge path. Our command examples are taken from Ubuntu and Fedora, but they apply to most other Linux distributions as well. 2. A well-organized hard drive is an efficient hard drive, but only if you plan your layout with the system's purpose in mind. 3. Dig your spurs in and get to know the boot process and the two most common boot loaders, LILO and GRUB, including how they work, how to configure them, and how to recover from common issues. 4.

Contents Preface I wrote this book really quickly as a way to bootstrap students for my other books. Many students don't know how to use the basics of the command line interface, and it was getting in the way of their learning. This book is designed to be something they can complete in about a day to a week and then get enough skill at the command line to graduate to other books. This book isn't a book about master wizardry system administration. Introduction: Shut Up And Shell This book is a crash course in using the command line to make your computer perform tasks. The only piece of advice I am going to give you is this: Shut up and type all of this in. Sorry to be mean, but that's what you have to do. You are not going to destroy your computer. Why? How To Use This Book The best way to use this book is to do the following: Just keep going through this process of doing an exercise, writing down questions you have, then going back through and answering the questions you can.

Ch03 : Linux Networking Now that you have a firm grasp of many of the most commonly used networking concepts, it is time to apply them to the configuration of your server. Some of these activities are automatically covered during a Linux installation, but you will often find yourself having to know how to modify these initial settings whenever you need to move your server to another network, add a new network interface card or use an alternative means of connecting to the Internet. In Chapter 2, "Introduction to Networking", we started with an explanation of TCP/IP, so we'll start this Linux networking chapter with a discussion on how to configure the IP address of your server. You need to know all the steps needed to configure IP addresses on a NIC card. This section shows you how to do the most common server IP activities with the least amount of headaches. Determining Your IP Address Most modern PCs come with an Ethernet port. Changing Your IP Address The "up" at the end of the command activates the interface.
howtoubuntu After Installing Ubuntu 14.10 Utopic Unicorn, there are a wealth of things that need to be dealt with, including Hardware Drivers, DVD, Audio and Video Codecs, Archiving formats, generally useful stuff. These instructions presume you are proficient with PPAs, .Debs, and other terminal commands, Ubuntu Tweak, and require a full set of video, audio, and archive codecs, as well as Skype, Flash, and a truck-load of wallpapers. Warning Using the sudo command can result in severe system damage. Make sure you type commands correctly, or copy and paste the entire code. 2. Both GetDeb and PlayDeb are repositories, sources of updates for actual software you have or will have installed. While this may look like an awful lot of code for something that should be relatively simple, you should know that while GetDeb and PlayDeb are repositories, they're not launchpad hosted, and hence a little more difficult to add. LibDVDCSS is a library required for reading some DVDs. 7. 8. 9. 10.

I found myself spending a ton of time adding drop shadows to images. convert screenshot.jpg \( +clone -background black -shadow 60×5+0+5 \) +swap -background white -layers merge +repage shadow.jpg Note: You must have Imagemagick installed for this command to work.
