Question

In LINUX Provide the command(s) and any additional steps to perform the following tasks. You will need to be running with root privileges.

1. Create a symlink to the /etc/openldap/ directory named "ldapconf" in /tmp/.

2. Find all .conf files in the /etc/ directory and its subfolders.

3. Find all directories starting with "gnome" or "GNOME" anywhere under the /usr/share/ directory.

4. Sam and Susan are members of the "sales" group. Sam has been working on a project that has grown too big for one person. You will need to move the project folder and update the permissions so they can share their work. Start by moving /home/sam/stuff to /home/shared/. Rename the folder to "salesproject".

5. Take a look at the permissions and ownership of the moved folder. Note that they didn't change. Recursively set the owner and group of /home/shared/salesproject/ and its contents to sam and sales, respectively.

6. Change the permissions of all files in the /home/shared/salesproject/ directory to allow the user and group to read and write but not execute. Disallow all access to everyone else on the system.

7. Change the permissions of the /home/shared/salesproject/ folder itself, allowing the owner and group full access, with no access for anyone else on the system.

8. Log in as "susan" (password "secret") and make sure she can access the /home/shared/salesproject/ directory and files within. Create a file in /home/shared/salesproject/ as susan. What are the owner, group, and mode of the file she created?

9. Log in as "sam" (password "secret"). Try to edit the file susan created. Why doesn't sam have access?

10. In order to guarantee that files created in /home/shared/salesproject/ are created with the "sales" group, set the SGID bit on the /home/shared/salesproject/ directory.
