Learning Objectives
Successfully complete this lab by achieving the following learning objectives:
- Add the Users to the Server
To add users to the system we can run
useradd <username>So we would run
useradd tstarkuseradd cdanversuseradd dprince- Create the `superhero` Group
To create a new group we would run
groupadd <groupname>So for this task
groupadd superhero- Set `wheel` Group as the the `tstark` Account’s Primary Group
For this task we would run
usermodlike thisusermod -g wheel tstark- Add `superhero` as a Supplementary Group on All Three Users
There isn’t an easy way to do this all at once, so we need to run the following command for each user
usermod -aG superhero <username>So
usermod -aG superhero tstarkusermod -aG superhero dprinceusermod -aG superhero cdanvers- Lock the `dprince` Account
To lock an account all we have to do is run:
usermod -L dprince
