User Management For Ubuntu/Debian And CentOS/RedHat Servers (Video)May 20, 2014 • By Panos Georgiadis
In this video, I am trying to teach your the very basics of user management in both Debian and Red Hat based distros. To do this, I am using two virtual machines in which I am connected to through SSH (secure shell) and then I am doing the same process: Create a user, elevate its privileges (to be able to use “sudo” commands) and then delete the user. In this video, we are going to modify the sudoers file which is locate under /etc/sudoers using the visudo program (specialized for this file). If you are running an older version of Debian prior to 7, you are going to need to install the sudo package (just use the apt-get install sudo command). Inside the video there are mistakes on purpose in order to observe how to do simple troubleshooting in case of getting similar errors. I am also showing you how to confirm the changes you’ve made.
