@Nes_Leon, the task asks for a non-interactive shell. Your user entry in /etc/passwd has a /bin/bash at the end. bash is an interactive shell

Hello Team,

I believe user have been created on the correct server with an interactive shell.

#54

Hello, @Preetesh
I haven’t read about /sbin/false. Can you please tell me why you used that? and any resource link?

#55

Hello Player001

Thank you so much for your response.

I have not used any link, as it was my practice to use “/bin/false” to disable shell for user which can be called a non-interactive shell.

Because I used /sbin/false the task failed, it should be /bin/false.

Some Useful links:

Hello, @Preetesh
Because you have added extra slash in the end of nologin. It’s /sbin/nologin not /sbin/nologin/. Hope it will clear your doubts.

#58

Thanks @Tej-Singh-Rana It worked :slight_smile:

#59

@hasmukhrathod…Please follow

ssh user@servername (e.g. ssh banner@stapp03)
adduser “name” -s /sbin/nologin (Make sure you try this from root )

  1. login to appserver
  2. sudo adduser username -s /sbin/nologin .
  3. to check if the user is created, use cmd compgen -u

HI @Elsevi ,

The --shell option specifies the user’s login shell. In this case, we are using the nologin shell, which is a non-interactive shell that prevents the user from logging in. This is often used for system accounts that need to run background tasks or services, but do not need to log in to the system.
