    Hello everyone

    We decided to create a separate post for this issue:

    1. Is it not possible to restrict users from having access to the entire /home/$user directory?
    3. Is it possible to create files by root that the user cannot edit?

    We are already using Cloud Linux but have found no way so far to accomplish any of these. We have tried setting ownership of files to 0444 and owner root but these settings are just overwritten by "File Manager".

    We have searched for quite a long time for any potential solution to "jail" users to only having access to the /home/user1/public_html directory but so far we haven't found any solution

    We appreciate any help

    -> You can try to add file attributes for it using chattr +ai and files that you want to restrict from file managers. So that change or modifications in file permissions and ownership could not be done and it will remain same as you defined.

    Further, It could not be possible that if a file is having a root.root ownership can get modified by a normal user. You need to assign sudo privileges to that particular user.

    Which specific service are you referring to (e.g. SSH, FTP)? Could you provide an example of where an account can access the entire /home directory through this service?

    Thank you.

    Hey Michael

    Sorry, what I meant to write was the user has access to the entire: /home/user directory where we would actually like them to only have access to /home/user/public_html

    I have tested this with several clients now following this procedure:

    1. Connect through SSH
    2. Create file test.foo
    3. chmod 444
    4. chown root:root test.foo

    Then I login with the user through domain.com/cpanel
    1. File Manager
    2. Edit file code or non-code
    3. Save
    4. Succes

    The file is now owned by user:user and nothing prevented them from doing this.

    It's not possible to limit a cPanel account's access to the public_html directory itself. You can create a virtual FTP account that can only access the public_html directory, but the cPanel account will always have access to it's home directory. I have opened an inquiry with our development team regarding the ability to access files owned by "root" within File Manager. For reference, the internal case number is 74121. I will update this thread with the answer when it becomes available.

    Thank you.

    Per the internal case:

    Thank you.
