Sudo is very important in securing your Linux system. $ sudo visudoĪnd add the following line as shown in the image. To do so, you have to use the visudo command which will open the sudo configuration file. You can also disable the password for the sudo command. You can set this parameter to 0 to always ask for a password.Į until the system is rebooted. This feature is controlled by the below parameter. So if you try to run any other commands immediately you won’t be asked to enter the password. Now, setting up a jail is a complicated matter, and is out of the scope of this question. Fortunately, users on Linux already have a home folder setup, so you can just use this jail. But an important thing to note is sudo will cache the password for some time once you run any command. What youre asking for is essentially known as a jail, wherein a user is confined to a certain subset of the system (like say, the home folder). Could you edit your question to include an example command with sudo that is failing and the exact error As for the password, you use your account password, not a different one. Run Command with Sudo Privileges Change Default Sudo Password TimeoutĮvery time when you run sudo you will be prompted for a password. 195 1 1 8 I’m a little confused about what you’re trying to do and what error you’re getting. Let’s try running the same apt command with sudo. Now you can run any command that the root user can run. To verify if a user is added to the sudo group run the id command. Any user that is part of the sudo group is granted sudo privilege. Now you need to add ubuntu20 to the sudo group. Use the Feedback tab to make any comments or ask questions. At the prompt, enter the new users password: email protected: sudo -i sudo password for newuser: email protected: Use whoami to verify that you are currently the root user: email protected: whoami root. User Permission Denied Error Add User to Sudo Group Use sudo -i to verify that the user account can elevate permissions. Try switching as an ubuntu20 user and try running the apt command, it will fail since it requires root privilege. To create the user run the following command. We will create a new user named ubuntu20 and grant him sudo privilege. Also with sudo, we can control which user can have access to which set of commands. Sudo allows you to run commands that require elevated privileges without switching into the root account. As you may be aware, any users who want to run commands that require root privileges need to either switch to the root account and submit the command or they should be part of the sudo group. Plus it manages FTP jails and similar automatically for you, allowing you to bypass the headache that is jailing.In this tutorial, we will see how to create a new user in Ubuntu 20.04 and how to grant sudo access to the user. Why not just use a control panel like Froxlor? It takes care of most of the heavy lifting for you, and allows you to set quotas and other things that may be of interest. And, as I mentioned before, running raw SSH is a really bad idea.įinally, it seems as though you're acting as a web host. The question you linked has a very good concept of how to jail users, but it only works with FTP and derivatives, not with raw SSH itself. There is no need for them to have a shell on your server. If you're just hosting a user, allow them to connect over FTP and just jail them to their "home" (the folder they have admin to). Now, assuming you have a working jail, you can just bind the proper folder to the user home: mount -bind /var/www/username /home/username/wwwĪlthough, this honestly is not a good option. Make sure you change username with the name of the user that you want to grant permissions to. Now, setting up a jail is a complicated matter, and is out of the scope of this question. To add the user to the group run the command below as root or another sudo user. This short tutorial will explain how to create a sudo user on Ubuntu 20.04 Focal Fossa Linux. What you're asking for is essentially known as a jail, wherein a user is confined to a certain subset of the system (like say, the home folder). A sudo user on the Ubuntu operating system is a user with root/administrative permissions.
