Access control method and system of network file system

Abstract

The invention discloses an access control method and system of a network file system. The method includes: receiving an access request from an NFS client; determining the network group which the client belongs to according to the client host name, client user name or client domain name; referencing the preset corresponding relationship of the network group and access authority, and searching for the access authority corresponding to the network group which the client belongs to; judging whether the access request is legal or not according to the searched access authority; if so, controlling the NFS client to access target files; or else, displaying a prompt message indicating that a user has no authority to access the target files. The access control method has the advantages that when an administrator configures the access authority of one network group, the access authority of all the members in the network group is configured in batch, the work load of the administrator is reduced, work efficiency is increased, and the setting manners of an authority management function is enriched.

Description

technical field [0001] The present invention relates to the technical field of network file systems, in particular to an access authority control method and system for network file systems. Background technique [0002] Network File System (NFS, Network File System), as the name implies, is a system that can perform various operations on remote files through the network. Its biggest function is to realize the sharing of files and directories between heterogeneous machines. Specifically, the client can transparently access the files stored on the remote NFS server just like accessing the local file system. In order to allow a large number of users to use without interference, different access rights are usually given to users at different levels. It can be seen that the access control of NFS is very important. [0003] At present, the authority control of NFS for hostnames and network IPs is well known to everyone, and the authority administrator needs to set the authority o...

AI Technical Summary

Problems solved by technology

However, with the continuous increase of network users, the number of host names or network IPs will increase, which means that the workload of authority administrators in authority management will be greatly increased, which will take a long time and reduce work efficiency.

[0004] It can be seen that the current access control method can no longer meet the needs of the cluster file system for NFS, and a new access control method for the network file system is urgently needed to reduce the workload of the authority administrator and improve work efficiency.
