Win7 NFS (tutorial on How to choose correct HS code in ASEANusing NFS file sharing in Windows 7) In the current Internet era, file sharing has become an indispensable part of our daily work. Whether it is work documents or entertainment content, we need to share them between devices for better use.In the Windows7 system, using the NFS protocol for file sharing can make file transfer more efficient and convenient. In this article, we will introduce the setting methods and precautions for Windows 7 NFS file sharing. I. Introduction to NFS Protocol NFS (Network File System) is a distributed file system protocol that allows remote computer systems to share files through the network. The NFS protocol runs on the application layer of OSI, based on IPv4 or IPv6 protocols, and communicates through TCP or UDP. In the NFS protocol, the client and the server communicate through RPC (Remote Process Call). II. Set NFS1. To set up NFS in the Windows 7 client, you need to install the NFS client component first.1. Open the "Control Panel" and enter the "Programs" tab. Two. Click "Enable or Disable Windows Functions". 3. In the list of Windows features, find "Services and File Sharing" and click Expand. Four. Select "NFS Client" and click the "OK" button. 5. Wait for the installation to be completed and restart the computer. Two. The server is set in the Windows 7 system, and the NFS server service is not turned on by default. Therefore, before using the NFS protocol for file sharing, the following operations need to be done to enable the NFS server service. 1. Open the control panel and select the "Program" option. Two. Click "Enable or Disable Windows Features" and find the "Services and File Sharing" option in the dialog box that opens. 3.Click "Service and File Sharing", then find "NFS Service" in the folder below, select it and click OK. Four. Wait for a few minutes until the NFS service is fully installed and configured. 5. Open the Windows firewall and add the inbound rules of the NFS service. The command is as follows: ```netsh advfirewall firewall add rule name="NFS Server(UDP)" dir=in protocol=udp action=allow Profile=any localport=111 netsh advfirewall firewall add ruThe name="NFS Server(TCP)" dir=in protocol=tcp action=allow profile=any localport=2049 netsh advfirew All firewall add rule name="NFS Server Mountd(TCP)" dir=in protocol=tcp action=allow profile=any loc Alport=32767 netsh advfirewall firewall add rule name="NFS Server Mountd(UDP)" dir=in protocol=udp action=allow profile=any localport=32767 ```III. Use NFS for file sharing 1. Configure the shared folder, select the folder you want to share, right-click on the folder, select Properties-->Share-->Advanced Sharing-->Share this folder, and then click the "Permissions" button. In the pop-up window, you can set the users and user groups for file sharing. Two. Open "Client" to the client connection server, click "Start", enter "cmd", right-click "Command Prompt" and select "Run as Administrator". Enter the following lifeTo connect to the NFS server: ```mount -o anon \\192.168.1.1\share C:\Mountpoint```Command options:? -o anon: If this option is referred to If it is, the client will connect to the NFS server anonymously.? \\192.168.1.1\share: This is the path shared on the server.? C:\Mountpoint: This is the local path on the Windows client. 3. Start the NFS client service, open "Service", select "Client to NFS" service, and then click "Start". III. Notes When using the NFS protocol for file sharing, the following matters should be noted: 1.Security issues Because NFS does not encrypt data when transmitting data, it is necessary to ensure the security of the network when sharing NFS files. Two. When using NFS for file sharing, you need to pay attention to the file permission problem. In the Windows system, permission control is very strict. You need to set accounts, passwords, permission groups, etc. in order to share files effectively. 3. Performance problems Because the NFS protocol is transmitted based on TCP or UDP, certain performance problems may occur when performing a large number of file operations. In order to improve the efficiency of file sharing, it is necessary to configure appropriate network bandwidth and performance optimization policies. To summarize, the NFS protocol can make Windows 7 file sharing more convenient and efficient, but it also requires us to follow certain operating specifications and precautions.Only in this way can we ensure that our file sharing can proceed smoothly and complete our work tasks smoothly. We hope that through the introduction of this article, you can have a deeper understanding of the NFS protocol and be able to flexibly use and configure the NFS protocol in the Windows 7 system.
