Permission Control for CVS + ACL in Linux

Article Title: Permission Control for CVS + ACL in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

I installed cvs-1.11.22-cvsacl-1.2.5-patched.tar.gz and used CVS + ACL for permission control under linux. But there are several problems:

1. According to the instructions on the acl website, perform initial configuration after installation and set the default permissions:

Execute cvs-d/opt/cvsroot racl ALL: r-r ALL, this is to set the default read-only permission for ALL users on the repository;

Then I run other acl commands, such as cvs-d/opt/cvsroot racl-l proj1. The system reports an error and the error message is as follows:

[Root @ bogon cvsroot] # cvs-d/opt/cvsroot racl-l proj1

Cvs [racl aborted]: received abort signal

What is this? When I enter/CVSROOT/access and cancel the default permission set, no error is reported. In addition, it is no problem to set permissions for individual users or groups. You can set permissions for ALL.

2. using acl to set a user's permission for a module to n (without any permission): Then, the user can retrieve the module from the client or retrieve all subfolders, only the files in the file cannot be seen. I want n users to not see all the content in the module. How should I set it?

When no acl is used in the past, I used chown and chmod to set the permission. If no permission is set, the folders and files in the module cannot be obtained. I want to use ACL to achieve this effect, instead of seeing the subfolders in it.
