Hi ! Linux expert
I am using redhat 8. I have setup nis Client and Server.
In /etc/profile (/etc/bashrc) how do I let a specific user access to a specific directory only everytime when he login with his login name.

For example,
User can access to his directory on any client machines in the network. Their access right (to access the directory) is depend on the user login name or UID. user_sales can only access to marketing directory. whereas, User_casher can only access to accouting directory.

I have setup the following in my nis server to make it available to other clients to share.
etc/exports
/home/accounting
/home/marketing

How can I write a program in /etc/profile (/etc/bash) to let user access his directory when he login. I am new to linux programming, I am trying to pick up along the way.

Appreciate if anyone can help.

I think you need to assign the user a "restricted shell". I'm sure it is covered in man bash but if you edit /etc/passwd for each machine the user might login on and make the shell /bin/bash -r I think this will do it.

<edit> Of course I'm assuming you have already set their home directory to either /home/accounting or /home/marketing

I've never used NIS, so you might have to modify the following accordingly.

You could do it by:
- adding groups using groupadd(8) called "accounting" and "marketing".
- Make the group owner of /home/accounting and /home/marketing the appropriate group.
- Turn on the Set Group ID (SGID) bit on the /home/accounting and /home/marketing so the files created there will have the appropriate group ownership.
- Turn off the permission bits that allow "others" into the directories.
- Add the appropriate users to the appropriate groups.

Wow, I sure used the word "appropriate" a lot!

Does this meet your requirements?
