Basic explanation: NFS Network File System

The purpose of the Internet is to share files. The first Internet is actually not the Internet. It should be a LAN. In order to better share our resources and expand the LAN, the Internet is formed. For sharing, we need to talk about the Network File System, NFS. NFS is short for Net File System, that is, Network File System.
 
The Network File System is one of the file systems supported by FreeBSD, also known as NFS. NFS allows a system to share directories and files with others on the network. By using NFS, users and programs can access files on the remote system just like accessing local files.

The following are the most obvious advantages of NFS:

1. The local workstation uses less disk space because the data can be stored on a machine and accessed over the network.
 
2. You do not have to have a home directory in each machine on the network. The Home directory can be placed on the NFS server and is available everywhere on the network.

3. Such as soft drive, CDROM, and Zip®Such storage devices can be used by other machines on the network. This reduces the number of removable media devices on the network.
 
NFS has at least two main parts: one server and one or more) clients. The client remotely accesses the data stored on the server. To work properly, some processes need to be configured and run.

NFS has many practical applications. Below are some common examples:

1. Multiple machines share one CDROM or other devices. This is cheaper and easier to install software on multiple machines.

2. In a large network, it may be convenient to configure a central NFS server to store the home directory of all users. These directories can be output to the network so that users can get the same home directory no matter which workstation they log on.

3. Several machines can have common/usr/ports/distfiles directories. In this way, when you need to install the port on several machines, you can quickly access the source code without downloading it on each device.

Note: NFS is developed by Sun microsystems. Is a network operating system that uses the underlying transport layer protocol TCP/IP application layer protocol.

A Network File System is one of the file systems supported by FreeBSD, also known as NFS. NFS allows a system to share directories and files with its users on the network. By using NFS, users and programs can access files on the remote system just like accessing local files.

How does NFS work?

NFS consists of at least two main parts: one server and at least one client. The client remotely accesses the data stored on the server. To make it all run, you need to configure and run several programs.

The server must run the following services:

Service Description

Nfsd NFS is the request service from the NFS client.

The mountd NFS mounting service processes requests submitted by nfsd (8.
 
Rpcbind This service allows NFS client programs to query the ports being used by the NFS service.

The client also runs some processes, such as nfsiod. Nfsiod processes requests from NFS. This is optional and can improve performance. It is not necessary for common and correct operations. For more information, see nfsiod (8.
