Lab 003: Create a Linux User with non-interactive shell

Requirements​

The System admin team of xFusionCorp Industries has installed a backup agent tool on all app servers. As per the tool's requirements they need to create a user with a non-interactive shell.

Therefore, create a user named anita with a non-interactive shell on the App Server 1.

Note

This lab demonstrates creating a Linux user with non-interactive shell for service accounts.

Prerequisites​

  • SSH access to App Server 1 with root or sudo privileges.
  • User management tools available (useradd, grep, su).

Steps​

Login to the app server and switch to root. For the server credentials, check out the Project Nautilus documentation.

sshpass -p  '******' ssh -o StrictHostKeyChecking=no tony@172.16.238.10
sudo su -
******  
[root@stapp01 ~]# useradd -s /sbin/nologin anita

[root@stapp01 ~]# grep anita /etc/passwd
anita:x:1002:1002::/home/anita:/sbin/nologin

[root@stapp01 ~]# su - anita
This account is currently not available.

Verification​

  • Confirm user anita exists with id anita.
  • Confirm shell is set to /sbin/nologin with grep anita /etc/passwd.
  • Confirm login attempt fails with "This account is currently not available".
