From this account, you can sudo without password so anyone who manages to run under your administrative user is essentially root. The following steps are helpful for enabling the “ NOPASSWD” configuration for a user on all commands. To sum up, you have an unprotected administrator user whose sole protection is that the username is uncommon (maybe).

How to Enable NOPASSWD for User in a Sudoers File Step 2: Enable the “NOPASSWD” Configuration.How to Enable NOPASSWD for User in a Sudoers File.This guide shows the complete procedure to edit the sudoers file and enable NOPASSWD for a user, all commands. To address this issue, the user can configure the “Sudoers” file so that commands can be executed without requiring the user to enter their password. A line like this: hadoopmaster ALL(ALL:ALL) NOPASSWD: su - hduser. which would do want you want, provided you had the appropriate lines in the sudoers file. So, youd want a command line like: sudo su - hduser. But for a long time, the user is irritated by typing the “sudo” password again and again for the system settings. You dont use 'su' with the sudoers file, you need to use 'sudo'. usr/local/dnsadmin/bin) Create a wrapper script for the commands you want them to make usable without sudo. I found sudo still popped up to ask me password even after I had added my user with ‘NOPASSWD: ALL’ in visudo.

It is very simple: Create a directory for a list of your sudo wrapper scripts (f.e. First of all, this is the version I’m using: lsbrelease -a LSB Version: 1.4 Distributor ID: Antergos Description: Antergos Linux Release: rolling Codename: ISO-Rolling. It generally asks for the administrator password for authentication while performing any task in the system. After you configure sudo, you can easily wrap this around the visible commands. While I expect this is a bug in Xenial, and certainly one I can’t quite wrap my head around, the solution is to create another user account that doesn’t bypass the sudo password requirement and setup the VNC server to use that account for storing it’s information.The “ Sudoers” administrator file stores the “ sudo” command line tool configuration. This affects pretty much anything that has to store a crypted key such as ssh, network-manager wi-fi authentication and VPN, etc. It seems to break PAM with regard to processing “secrets”, referenced in syslog, by the “Secret Service”.

Note: My previous article about a VNC Server at boot creates an unusual interaction when referencing a user that bypasses the password requirement for sudo. At the end of /etc/sudoers there is what I thought was just a comment: includedir /etc/sudoers. Sure enough, there is no prompt for password using the sudo command. 6 Answers Sorted by: 389 Okay, I have discovered the answer so may as well put it here for completeness.

The /usr/bin/apt update makes adding an option first like sudo apt -q update passwordless. The /usr/bin/apt update makes the basic command sudo apt update passwordless. The “wheel” group doesn’t exist on my Ubuntu Xenial so: The most robust way that I can see to do this is: sudo ALL (root) NOPASSWD: /usr/bin/apt update, /usr/bin/apt update, /usr/bin/apt update. Session required pam_env.so readenv=1 envfile=/etc/default/locale common-session-noninteractive Session required pam_env.so readenv=1 user_readenv=0

What about sudo? Is it possible to use that same line in “/etc/pam.d/sudo”? # Uncomment this if you want wheel members to be able to This references the following note found in “/etc/pam.d/su”: My search led me to password – How to setup passwordless ‘sudo’ on Linux? – Server Fault Later you can view these with: ssh-keygen -lv Enter file in which the key is (/home/training/. I know about sudoers file and NOPASSWORD parameter. That means I still need to generate passwords for these users and figure out how to securely get it to them. This information can be shared with other people who may need to verify your public key. However, this process becomes useless when these users need to run sudo- the server is still asking for their passwords. Each of these servers has no more than 5 users including admins, and there's a mix of password and key-based ssh happening. In this tutorial, you saw how to disable the sudo password on Ubuntu 22.04 Jammy Jellyfish Linux. After generating the key pair, the ssh-keygen command also displays the fingerprint and randomart image that are unique to this key. Where does passwordless sudo fit in to industry standards and security best practice At work I'm a generalist admin, and now I have a half-dozen Red Hat based servers to deal with. I was looking for a way to run sudo without having to enter a password each time, like it is with Raspbian. Lastly, in case you need all members of the sudo group to execute any commands using passwordless sudo, change the configuration line from Step 1 to: sudo ALL(ALL:ALL) NOPASSWD:ALL Closing Thoughts.
