在Linux系统上为用户设置权限，以使他们无法访问父目录

Question

I create a user with useradd and edited the /etc/passed file but the user can still see parent and can go in to parent directorys

how can I restrict him from going into parent directory.

Answer 1

Why do you want that? What are exactly the parent directory?

Often, the home directory of user foo is ~foo ie /home/foo

It depends upon the permissions on others home directories. So if there is user bar you might chmod o-rwx /home/bar ; and you could set up groups and group permission, etc...

Or perhaps try (with caution and care) chmod o-rwx /home/

You could also use some restricted shell for foo eg rbash or rssh , configure it wisely, and chsh foo /bin/rbash
