![]() ![]() ![]() Now let’s add the new user to sudo group by using usermod command. For that, we need to add the new user to the sudo group. New users by default, will not be able to modify files out of their home directory. You can leave all of this information blank, just hit Enter. Once the password is successfully set, the command will ask about additional information of the user. This command will prompt you to enter the password for the new user’s account and then confirm it by retyping. # adduser newusernameįor example, here we are adding nick as the new user. To create a new user we are going to use adduser command here. Then you will typically receive a password through email use this password to login. If you have created a server instance without selecting an SSH key to use for authentication. Let’s start by logging in as a root user on Debian server via SSH # ssh replace server_ip_address with the IP address of your server. In this guide, we will see how to create a new user and then add that user or any other user to sudoers group on Debian. But the condition here is that the user who wants to use sudo needs to be in the sudo group on Debian. Basically sudo lets a regular user exercise some of the superuser powers. For instance, when a regular user wants to perform administrative tasks they can perform using sudo command. So to perform everyday administrative tasks sudo comes in. And Linux doesn’t even have an Undo option making another root account is risky. But we can’t make everybody a root user as it will be extremely dangerous. Tasks like installing, updating, upgrading, deleting important files, modifying configuration files, starting and stopping system services require root powers.Īs these tasks can modify the system and sometimes even harm the system they require root privileges. A superuser is a root user that has full system access and can do pretty much everything on the system. UAC is like sudo, where you only escalate privileges when you need to, and at other times, you stay put with limited access.Sudo stands for superuser do means whats superuser can do. So unless you really need to, there’s no point in using the root account. And that’s more than enough to give you an idea of how devastating root access in the wrong hands can be. As a root user, you can perform rm -rf / and delete the entire system without any obstacles. If you use root as your user regularly, you’ll be exposing yourself to the risk of giving a malicious application full access to your system. ![]() This is exactly why we need sudo and root users to be different. With UAC, most applications run with limited access and only when a system file needs to be modified, Windows prompts the user asking for permission. The fact that any software running under the user has full privileges to perform any action on the system. User Access Control (UAC) was introduced in Windows because staying logged in as an Administrator posed a very obvious security risk. In Windows, we’re used to logging into the administrator account and using things directly as an administrator. This is a common question among new users who’ve been using Windows and have recently switched to Linux. You now know both the ways of adding users to sudoers! Great job. Now when the user logs in for the first time after this new group is added, they’ll get a message like the one below notifying them of the change in privileges. The sudoers file is typically located at ‘ /etc/sudoers‘. ![]() The sudoers file defines a list of rules that specify what commands a user can run and as what user, and also controls the level of access they have to the system. The sudoers file is a configuration file in Unix-based operating systems, including Ubuntu, that determines which users or groups have the permission to use the sudo command to perform privileged tasks. In this article we will explore how to grant sudo privileges to a user or a group of users. This way, users can still perform system-level tasks without the risks associated with being logged in as the root user. Instead, it uses a feature called sudo, which allows authorized users to perform administrative tasks without logging in as root. Especially in an enterprise setup this would mean disaster. Most of the Linux Distributions don’t allow ‘root’ user also known as superuser by default as a security measure to prevent accidental or intentional changes that could harm the system. ![]()
