Learn how to administer and manage users, user accounts, user groups, permissions, privileges, and access-related settings in Linux.
- [Grant] Linux servers around the world have millions of users logging in to them every day. Being able to manage those users is a necessity for businesses to function. Welcome to Linux: User and Group Management, I'm Grant McWilliams, Computer Science instructor and Linux enthusiast. In this course, we'll learn how to create users and groups in Linux. We'll learn about managing passwords, locking user accounts, and account aging. We'll spend some time learning about one-way hashes, and how to configure out hashes for Linux passwords. We'll use SU, SUDO, and GNU group to elevate privileges, so we don't have to log in as root, making our system more secure.
I love Linux, and I'm excited to teach you about it, so let's get started.
- Identify what data is stored in the /etc/passwd file with the shadow suite installed.
- Name the file that Linux group password hashes are stored in when the shadow suite is installed.
- Describe how to override default account aging information.
- Explain how to elevate privileges using the sudo command.
- Name the command that a user can use to change their effective primary group.
