When it comes to administering an operating system, you need to know how to add, change, and remove users and groups. You must also be able to create files and folders with set permissions for those users and groups. In this problem set, we will do just that. Let's look at a fictitious company named Big Sky Outdoor Supply. BSOS will have two users that will log into the server. They are:

Roger Clemens $-$ Finance Manager

Nolan Ryan $-$ HR Manager

Each user will need access to their secure home directory and each will need access to a shared area on the machine. Here are the details on the shared area:

Finance Reports Folder $(/$srv$/$finance$\_$reports$)=$ Roger should have full permissions but everyone else should only have read permissions

Shared Managers Folder $(/$srv$/$managers$)=$ Both Nolan and Roger should have read and write access but no execute, no others will have access to this folder

Let's get started building this setup:

Open a terminal in your Ubuntu Server.

Create a 'finance' and a 'managers' group

Create the users with the following information:

Roger Clemens

Username: rclemens

Password: Password$123$

Groups: finance, managers

Nolan Ryan

Username: nryan

Password: Password$123$

Groups: managers

Open the $/$etc$/$passwd file in VIM. Using the TealVirt 'Capture Screenshot Package' option, capture a screenshot PDF of the contents of the $/$etc$/$passwd file showing both new user accounts. This will be screenshot #$1.$

Close the file

Open the $/$etc$/$group file in VIM. Using the TealVirt 'Capture Screenshot Package' option, capture a screenshot PDF of the contents of the $/$etc$/$group file showing both new groups and their membership. This will be screenshot #$2.$

Close the file.

Create the folders mentioned in the scenario above. Go to the $/$srv$/$ directory to create the needed folders.

Set the folder permissions of 'finance' to be:

Group Owner: finance

Group Permissions: read, write execute

Other Permissions: read, execute $($to allow browsing$)$

Set the folder permissions of 'managers' to be:

Group Owner: managers

Group Permissions: read, write, execute

Other Permissions: none

Move out to the $/$srv directory and perform a long listing $($ll$)$ so the permission structures of both directories is visible.

Using the TealVirt 'Capture Screenshot Package' option, capture a screenshot PDF showing the permissions on those two directories. This will be screenshot #$3.$
