acl generator

When talking about a complex permission control with a friend yesterday, I mentioned that I could try ufs2 acl. When I published the 5.0 feature, I was first interested in the various features of ufs2, especially the acl. However, it turns out that this acl is different from the kind of acl in my ideal ntfs. By the way

ACL: An access control list that is used primarily for setting permissions on files or directoriesHow to use:Getfacl [file]: View this file ACL permissionsSetfacl [-BKNDRLPVH] [{-m|-x} Acl_spec] [{-m|-x} Acl_file] File ...Special permissions:Mask Permission: This permission is the maximum effective permission, which is the final permission when the permissions set for the user or group have the same permiss

Access control list ACL is mainly used in a corporate LAN, some departments or staff access to make rules, traffic filtering, and not only LAN, if you know the external network segment and port, can also be limited.ACL Considerations:1) Rule entries in a table cannot have conflicting existence2) Default deny all traffic for all hosts after ACL table is established3) Because the

Lightweight "set" iterator-Generator, set-generator Generator is a new language feature added to PHP 5.5. However, it does not seem to be widely used by many PHP developers. Therefore, before learning about the improvements made by PHP 7 to Generator, let's take a simple but obvious example to understand what problems

Project Practice 4-haproxy Server Load balancer and ACL control, haproxyacl Haproxy implements advanced Load Balancing Environment: With the development of the company's business, the company's server Load balancer service has achieved layer-4 Server Load balancer, but the business complexity has increased, the company requires the mobile phone site as a separate service to provide, if you do not provide services with the pc site, you need to perfor

I. Common ACL rulesThe ACL of the Haproxy is used to make forwarding decisions based on the header of the request packet, the content of the response message, or other environmental state information, which greatly enhances its configuration flexibility. The configuration rule is usually divided into two steps, defining an ACL first, defining a test condition,

Zookeeper as a configuration management service, because the configuration data has a high security requirements, need to have permission control, the client needs to login authentication before operation (view data, modify data, create children Znode, etc.) zookeeper above corresponds to Znode. 1.

Linux general permissions generally do not meet the shared needs, such as NFS and samba.Especially samba is the most obvious.With an ACL, mom doesn't have to worry about file permissions anymore.ACL permissions are set to two commands: Setfacl set permissions, Getfacl get ACL permission information for the file.Simple is an example:The ACL is set in a directory w

When creating an ACL on a vswitch, you can use a string or a number to name the ACL. Generally, you can use a string + a number to name the ACL for easy identification; the standard ACL or extended ACL is identified by fields. For example, standard

Linux ACL and linuxacl Common file and directory permission management can only be performed for owners, group users, and other users. After permission distribution is diversified, common file and directory permission management is used to increase complexity, you can use ACL (full name Access Control List) to manage permissions flexibly. First, check whether the partition supports

immediately exit, but the specified time is idle, and the new task is processed immediately if a new task arrives before the idle threshold time arrives, such as If no new tasks arrive after the idle timeout is reached, these idle threads or processes exit to yield system resources. Therefore, compared with the resident memory mode and semi-resident memory mode, it is not difficult to see that the semi-resident mode is more on demand.The following is an example of how to write a semi-resident t

Python-Generator/point you don't know, python-generator1. What is a generator? By using the list generation method, we can directly create a list. However, due to memory restrictions, the list capacity must be limited. In addition, creating a list containing 1 million elements not only occupies a large storage space, but if we only need to access the first few elements, the space occupied by the vast majori
