Mastering Ubuntu Server

Managing Users and Permissions

In the previous chapter, we set up our very own Ubuntu Server installation, and we can now learn how to maintain it, starting with a look at managing who is able to use our server.

As an administrator of Ubuntu servers, users can be your greatest asset and also your biggest headache. During your career, you'll add countless new users, manage their passwords, remove their accounts when they leave the company, and grant or remove access to resources across the filesystem. Even on servers on which you're the only user, you'll still find yourself managing user accounts, since even system processes run as users. To be successful at managing Linux servers, you'll also need to know how to manage permissions, create password policies, and limit who can execute administrative commands on the machine. In this chapter, we'll work through these concepts so that you'll have a clear idea of how to manage users and their resources.

In particular, we will cover:

  • Understanding users and groups
  • Understanding when to use root
  • Creating and removing users
  • Understanding the /etc/passwd and /etc/shadow files
  • Distributing default configuration files with /etc/skel
  • Switching users
  • Managing groups
  • Managing passwords and password policies
  • Configuring administrator access with sudo
  • Setting permissions on files and directories

In the first section, we have a quick discussion of the nature of managing users.

This is a great book. While it's not absolutely comprehensive, it covers everything an average dev or sysadmin is likely to need in order to get up and running with Ubuntu. It's written in clear approachable language anyone moderately technical should have no trouble with, and manages to offer both enough basics for junior users to get things figured out, yet enough pro tips/tricks and best practices to still be a good resource for seasoned pros. This book is winner.

I am very happy I purchased this book. The way it is written provides clear in- depth explanations and tutorials. It help you become proficient in Linux, especially Ubuntu server edition. The information is good for most distros of Linux and is a great reference book as you are learning. I follow Jay LaCroix on youtube and he is the reason I use Linux as my OS and have an Ubuntu server running in my home. Amazing instructor, awesome book!
