An ACL is an abbreviation for Access Control List. The basic purpose is to provide a detailed permission configuration beyond the Read,write,execute permissions of the traditional owner,group,others. ACLs can be used for single-user, single-file or folder-r,w,x permission specifications, which is useful for situations where special permissions are required.What are the main areas in which ACLs can control p

. If there is an X on that bit, then these special flags (SUID, sgid, sticky) are shown as lowercase letters (s, s, t), otherwise they are shown as uppercase letters (s, s, T). 3, there is also a large x permission, followed by the ACL will also be mentioned. Second, ACL 1. Enable ACLs Under the XFS and Ext4 file system under Rhel 7, ACL rules have been supported by default (EXT4 already supported by default in RHEL6)---fstab are already integrate

We know that access to files is based on the three types of files belonging to the owner, group, and other users, and ACLs provide more detailed permission settings beyond those three. ACLs can set permissions on single users and directories and files, which is useful for special permissions. Suid and Sgid These special permissions that were mentioned earlier, but these special permissions and

[Email protected] ~]# setfacl-m u:instructor:rwx/home/project/ You can remove a user from an ACL by using the "setfacl-x" command.Example: Remove the instructor user from the ACL.

For Cisco VLAN ACLs first have to define the standard ACL or extented ACL for the selected trafficNote that the selected traffic here is not the final operation on traffic, but rather determines what traffic is handled with VLAN ACLsIf there is no standard ACL or extented ACL that represents this traffic complete release for VLAN ACLs. GeneralThe standard ACL or extented ACL has only permit statements.Confi

Zookeeper uses ACLs to control access to nodes, and ACLs are implemented similar to access permissions for UNIX files: use BITS to control the scope and access permissions for node access. But unlike UNIX file systems, for standard scopes, including user (owner of file), group and World (other), zookeeper nodes are not limited. Zookeeper does not have the concept of a znode owner, instead,

The Linux File System provides the rwx permissions defined by the owner, owning group, and other users (other) for each type of users, and they are independent of each other. Although Linux supports the special file permissions of LinuxPermission control can be precise to users and groups (for example, allowing a file to be modified by a special user and allowing users in a group to view the permissions ).These are obviously not enough. Fortunately, Linux also supports
