Network File System (NFS) I. Introduction to NFS 1. NFS is short for Network File System. Its biggest function is to allow different machines and operating systems to share files with each other over the network) -- you can mount the directory of the remote host through NFS. Accessing the directory is like accessing th

1. Configure the firewallProperly configure the firewall filtering rules, otherwise it will cause NFS file system mount failure, NIS account authentication failure, MPIRun remote task instance delivery failure. In general, the compute cluster is used on the internal LAN, so you can shut down the firewall of all node servers without having to worry too much about security issues.The relevant commands are as

A contract for the decentralized file system, developed by Sun, was announced in 1984. The function is to enable different machines, different operating systems to share individual data with each other, so that the application can access

NFS for CentOS NFS is an old protocol, and it has been constantly updated and improved in Linux. Previously, it only supports UDP, TCP, and V4. But it is still insecure. The biggest problem is that identity authentication is not required. We recommend that you use it on the intranet only.The NFS server is the service p

No authentication method After a correct client request is sent to the server, the HTTP server returns the 200 status code and directly returns the content. Message example: Request: Get. http: // 10.127.194.3: 8061/voiceobjects ..... Return Value: HTTP/1.1.200. OK .date:. Fri,. 28. oct.20 ..... Ii. Basic Authentication Method The Basic Authentication and digest

If you want to define authentication, my personal preference is that authentication is an action to determine whether the real identity of the authenticated party matches the identity of the authenticated party or her Claim (Claim. The authenticated party must provide the relevant proof of identity to identify whether the identity is consistent with the claimed identity. In computer languages, the Identity

RO or RW, will be able to access, using FTP, RO and RW are the same, for host access, read and write by the group access configuration decision, meaning that when using FTP, RO and RW permissions are configured with group access.About Primary Group (PG), because the user of Openfiler can join multiple groups, therefore must have the PG attribute, and then through the host access authentication, the role of the PG attribute will be reflected, the actu

What is NFS (network filesystem) 　 Before we start the NFS Setup, let's take a look at what NFS is. It's no use talking about a bunch of them, right. ^_^. The so-called NFS is the abbreviation of network filesystem, which was first developed by the Sun company. His biggest feature is the ability to share individual f

use semi-structured data. Such data can fully describe the meaning of its own data without being parsed by the other party, such as XML, JSON, RESTful transmission is based on http. For user authentication, we used NIS (Network Information System, 2049/tcp, 2049/udp) earlier. This Protocol transfers user authentication to a remote server instead of a local server. However, this
