Enter the password you used to create the user and not the root password to proceed: password for username: All members of the sudo group granted sudo and root-level access on Ubuntu and Debian based systems. It is time to add the wendy user account to the sudo group. Now we have added a user named wendy with a password. The first time you use sudo in a session, you will be prompted to enter the password. Step 3 Add the new user to the sudo group. Let us list the contents of the /root directory, which is something only the root user can do: $ sudo ls -la /root To use sudo privilege, prefix any command with sudo and space.

This allows non-root users to execute commands with the security privileges of another top-level root, by default, the root user. ![]() The sudo configuration is managed by the /etc/sudoers file.The sudo command in Linux provides a mechanism for granting administrator privileges to normal users. With sudo the user can (and probably should) be required to provide a password in order to execute the application. Im also using ansible and more specific ansiblelocal (Vagrant plugin) to deploy some tools into the VM. We can do this by adding the user to the wheel group (which gives sudo access to all of its members by default). Im using Vagrant (Virtual Box provider) to setup a local Virtual Machine. If the setuid bit is set on an executable, any user would be able to run the application (or any user of a certain group, depending on the permissions used). If your new user should have the ability to execute commands with root (administrative) privileges, you will need to give the new user access to sudo. With sudo a clear list can be made of who can execute a certain application. Unlike using the setuid bit on these applications sudo gives a more fine-grained control on who can execute a certain command and when. The app-admin/sudo package allows the system administrator to grant permission to other users to execute one or more applications they would normally have no right to. This is very useful when tracking who made that one fatal mistake that took 10 hours to fix :) One additional advantage of sudo is that it can log any attempt (successful or not) to run an application. Root # emerge -ask app-admin/sudo Configuration Logging activity
