How to open NFS. What is the NFS file extension? Programs serving the NFS file

When it comes to computer networks, Often you can hear the mention of NFS. What does this abbreviation mean?

This is a protocol of a distributed file system, originally developed by Sun Microsystems in 1984, allowing the user on the client computer to access files through the network, like access to the local storage. NFS, like many other protocols, is based on the Open Network Computing Remote Procedure Call system (ONC RPC).

In other words, what is NFS? This is an open standard defined in Request for Comments (RFC), which allows you to implement a protocol.

Versions and variations

The inventor used only the first version for its own experimental purposes. When the developer team added significant changes to the initial NFS and released it outside the authorship of the Sun, they denoted new version As v2 so that you can test the interaction between distributions and create a backup option.

NFS V2.

Version 2 originally worked only on the User Datagram Protocol (UDP) protocol. Its developers wanted to save the server side without blocking implemented outside the main protocol.

The interface of the virtual file system allows you to perform modular implementation reflected in the simple protocol. By February 1986, solutions were demonstrated for operating systems such as System V Release 2, DOS and VAX / VMS using EUNICE. NFS V2 allowed to read only the first 2 GB of the file due to 32-bit restrictions.

NFS V3.

The first offer to develop NFS version 3 in Sun Microsystems was voiced shortly after the release of the second distribution. The main motivation was an attempt to mitigate the problem of performance of a synchronous recording. By July 1992, practical improvements made it possible to solve many shortcomings of NFS version 2, while leaving only insufficient support for files (64-bit sizes and file offset).

  • support for 64-bit sizes and file displacements for data processing of more than 2 gigabytes (GB);
  • support for asynchronous recording on the server to increase productivity;
  • additional file attributes in many answers to avoid the need to re-extract them;
  • rEADDIRPLUS operation for data and attributes along with file names when scanning directory;
  • many other improvements.

During the introduction of version 3, TCP support as a protocol transport level Began to increase. Using TCP. As a means of transmitting data made using NFS via WAN, it began to transmit large file sizes to view and write. Thanks to this, the developers were able to overcome the limits of restrictions in 8 KB, imposed by the user datagram protocol (UDP).

What is NFS V4?

Version 4, developed under the influence of the Endra File System (AFS) and the Server Message Block (SMB, also called CIFS), includes an increase in performance, provides better security and enters the protocol in compliance with the established conditions.

Version 4 became the first distribution developed in Target group Internet Engineering Task Force (IETF) After Sun Microsystems has passed the development of protocols to third-party specialists.

NFS version 4.1 is aimed at providing support for the protocol to use cluster server deployments, including the ability to provide scalable parallel access to files distributed between multiple servers (PNFS extension).

The newest File System Protocol - NFS 4.2 (RFC 7862) - was officially released in November 2016.

Other extensions

With the development of the standard, the corresponding tools for working with it appeared. Thus, WebNFS, extension for versions 2 and 3, allows the network access protocol to file systems easier to integrate into web browsers and activate work through firewalls.

The various protocols of third-party groups have also become associated with NFS. Of these, the most famous are:

  • Network Lock Manager (NLM) with byte protocol support (added to support UNIX System V files);
  • remote Quota (RQUOTAD), which allows NFS users to view data storage quotas on NFS servers;
  • NFS via RDMA - adaptation NFS, which uses remote direct memory access (RDMA) as a means of transmission;
  • NFS-Ganesha is a NFS server that works in user space and supporting CEPHFS FSAL (file system abstraction) using libcephfs.

Platform

NETWORK FILE SYSTEM is often used with operating uNIX systems (such as Solaris, AIX, HP-UX), MacOS from Apple and UNIX-like OS (such as Linux and FreeBSD).

It is also available for platforms such as ACORN RISC OS, OpenVMS, MS-DOS, Microsoft Windows, Novell NetWare and IBM AS / 400.

Alternative protocols remote access Files include a server message block (SMB, also called CIFS), Apple Transmission Protocol (AFP), NetWare Basic Protocol (NCP) and OS / 400 Server File System (QFilesVR.400).

This is due to the requirements of NFS, which are focused mostly on UNIX-like "shells".

Wherein sMB protocols and NetWare (NCP) are used more often than NFS, in systems running Microsoft Windows.. AFP is most widespread in Apple Macintosh platforms, and QFilesVR.400 is most often found in OS / 400.

Typical implementation

Assuming a typical Script in the UNIX style, in which one computer (client) needs access to data stored on another (NFS server):

  • The server implements the default NETWORK File System processes as NFSD to make their data publicly available to customers. The server administrator determines how to export the names and parameters of the directories, usually using the configuration file / etc / exports and the ExportFS command.
  • Server Security Administration ensures that it will be able to recognize and approve a proven client. The configuration of its network ensures that the relevant customers can negotiate with it through any firewall system.
  • The client machine requests access to exported data, as a rule, by issuing an appropriate command. She requests the server (rpcbind) that uses the NFS port, and subsequently connects to it.
  • If everything happens without errors, users on the client machine will be able to browse and interact with the installed file systems on the server within the allowed parameters.

Attention should also be paid to the fact that the automation of the Network File System process can also occur - possibly using ETC / FSTAB and / or other similar means.

Development today

By the 21st century, DFS and AFS competitors did not reach any major commercial success compared to Network File System. IBM company, which previously acquired all commercial rights to the above technologies, donated to the most source code AFS Community Free Developers software in 2000. The Open AFS project exists today. In early 2005, IBM announced the completion of Sales AFS and DFS.

In turn, in January 2010, Panasas suggested NFS V 4.1 based on technology that allows you to improve the possibilities of parallel access to data. Network File System V 4.1 protocol Specifies the method of separating the metadata of the file system from the location of certain files. Thus, it goes beyond the simple division of names / data.

What is NFS this version in practice? The above feature distinguishes it from a traditional protocol that contains file names and their data under one binding to the server. When implementing Network File System V 4.1, some files can be distributed between multi-numeral servers, but the client's participation in the separation of metadata and data is limited.

When implementing the fourth distribution, the NFS server protocol is a set of server resources or components; It is assumed that they are controlled by the metadata server.

The client still refers to one metadata server to bypass or interact with namespace. When it moves files to the server and from it, it can directly interact with the data set belonging to the NFS group.

The table below provides useful information about the extension file.nfs. He answers questions such as:

  • What is a file. nfs.?
  • Which software I need to open the file. nfs.?
  • As a file. nfs. Be opened, edited or printed?
  • How to convert. nfs. Files to another format?

What is NFS file?

NFS File name suffix is \u200b\u200bmainly used for Network Format System Temporary Format files. File format NFS Compatible with software that can be installed on the Linux system platform. NFS File format, along with #Numextensions # other file formats, refers to the category Other files. To manage NFS files is recommended. Network File System..

Programs that support NFS file extension

Below is a table with a list of programs that support NFS files. Files with the NFS extension, like any other file formats, can be found in any operating system. Specified files Can be transmitted to other devices, whether mobile or stationary, but not all systems can be able to correctly process such files.

How to open the NFS file?

Problems with access to NFS can be caused by different reasons. Fortunately, the most common problems with nFS files They can be solved without deep knowledge in the field of IT, and most importantly, in minutes. Below is a list of recommendations that will help you identify and solve problems related to files.

Step 1. Install Network File System Software

Problems with opening and work with NFS files are most likely associated with the lack of proper software that is compatible with NFS files on your computer. The solution to this problem is very simple. Upload Network File System and install it on your device. Full list Programs grouped by operating systems can be found above. One of the most safe ways Software loading is the use of references official distributors. Visit the Network File System website and download the installer.

Step 2. Upgrade Network File System to the latest version.

You still can't access NFS files, although Network File System. Is installed in your system? Make sure the software is updated. It may also happen that software creators, updating their applications, add compatibility with other, newer file formats. This may be one of the reasons why NFS files are not compatible with Network File System. All file formats that are well processed previous versions This program should also be open using Network File System.

Step 3. Tie Network Format System Temporary Format with Network File System

If you have installed latest version Network File System and the problem is saved, select it as a default program that will be used to control NFS on your device. The method is quite simple and changes little in different operating systems.

Windows

  • Pressing the right mouse button on NFS will open the menu from which you must select the option. To open with
  • Choose Select another app → More applications
  • To complete the process, select Find another application on this ... And with the help of the conductor, select the Network File System folder. Confirm Always use this application to open NFS files And clicking the OK button.

Change the default application in Mac Os.

  • By pressing the right mouse button on the selected NFS file, open the file menu and select Information.
  • Find option To open with - Click the title if it is hidden
  • Select the appropriate program from the list and confirm by clicking " Change for all » .
  • A window should appear with a message that this change will be applied to all files with the extension NFS. Pressing forward, you confirm your choice.

Step 4. Make sure NFS is not faulty

If you executed instructions from previous steps, but the problem is still not solved, you should check the NFS file, which is discussed. Problems with the opening of the file may occur for different reasons.

1. NFS can be infected with malicious software - be sure to check it with antivirus.

If NFS is really infected, perhaps malware blocks its discovery. It is recommended to scan the system as soon as possible for viruses and malicious programs or use an online anti-virus scanner. If the scanner detected that the NFS file is unsafe, act in accordance with the instructions antivirus program To neutralize the threat.

2. Make sure the NFS file structure is not damaged.

If you got a problematic NFS file from a third party, ask for it to provide you with another copy. It is possible that the file was not properly copied to the data warehouse and is incomplete and therefore cannot be opened. This may occur if the download process file with NFS extension It was interrupted and file data is damaged. Load the file again from the same source.

3. Make sure you have appropriate access rights

Sometimes, to access the files, the user needs administrator rights. Exit your current account and log in to account With sufficient access rights. Then open the Network Format System Temporary Format file.

4. Make sure your device meets the requirements for opening Network File System

If the system is not enough resources to open NFS files, try closing all running in this moment Applications and try again.

5. Make sure your operating system And drivers updated

Regularly updated system, drivers and programs ensure the security of your computer. It can also prevent problems with network Format System Temporary Format files. It is possible that one of the available system updates or drivers can solve problems with NFS files that affect older versions of this software.

Network file system NFS or Network File System, this is a popular network file system protocol that allows users to connect deleted network directories on their machine and transmit files between servers. You can use disk space on another machine for your files and work with files located on other servers. In essence, this is an alternative to the general windows access For Linux, unlike Samba is implemented at the kernel level and works more stable.

This article will consider installing NFS in Ubuntu 16.04. We will analyze the installation of all required components, set up a shared folder, as well as connecting network folders.

As already mentioned, NFS is a network file system. To work, you need a server on which will be posted a shared folder and customers who can mount network folder as a regular disk in the system. Unlike other NFS protocols, provides transparent access to remote files. Programs will see files as in a regular file system and work with them as with local files, NFS returns only the requested part of the file, instead of the entire file, so this file system will work perfectly in systems with quick Internet or on the local network.

Installing NFS components

Before we can work with NFS, we will have to install several programs. On the machine that will be the server you need to install the NFS-Kernel-Server package, with which the NFS balls will be opened in Ubuntu 16.04. To do this, follow:

sudo Apt Install NFS-Kernel-Server

Now let's check the server correctly installed. The NFS service listens to the connection for both TCP and UDP on port 2049. Whether these ports are really used now.

rpcinfo -p | Grep NFS.

It is also important to check whether NFS is maintained at the kernel level:

cat / Proc / FileSystems | Grep NFS.

We see that it works, but if not, you need to manually load the nfs kernel module:

Let's add NFS to autoload:

sudo SystemCTL Enable NFS

On the client computer you need to install the NFS-COMMON package to be able to work with this file system. You do not need to install the server components, it will only be enough for this package:

sudo Apt Install NFS-COMMON

Setting up NFS server in Ubuntu

We can open NFS access to any folder, but let's create a new one for these purposes:

address_pads Client (Options)

The address of the folder is the folder that needs to be made available over the network. Client - IP address or network address from which you can access this folder. But with options a little more difficult. Consider some of them:

  • rW - Allow reading and writing in this folder
  • ro. - Allow only reading
  • sync. - respond to the following requests only when the data is saved to the disk (default)
  • async. - Do not block connections while the data is written to the disk.
  • secure - Use only ports to connect only 1024
  • insecure. - Use any ports
  • nohide. - Do not hide the subdirectory when opening access to multiple directories
  • root_squash - Submissive ROOT requests for anonymous
  • all_squash - turn all requests to anonymous
  • anonuid. and anonyd. - Indicates UID and GID for an anonymous user.

For example, for our folder, this string may look like this:

/ VAR / NFS 127.0.0.1 (RW, Sync, No_Subtree_Check)

When everything was configured, it remains to update the NFS export table:

sudo Exportfs -a.

That's all, the opening of the NFS balls in Ubuntu 16.04 completed. Now we will try to set the client and try to attach it.

Connect NFS

We will not dwell on this issue in today's article. This is a rather large topic that deserves a separate article. But I'll tell you a few words.

To connect the network folder you do not need any NFS client Ubuntu, it is enough to use the Mount command:

sudo Mount 127.0.0.1:/var/NFS/ / MNT /

Now you can try to create a file in the connected directory:

We also see the connected file systems using DF:

127.0.0.1 :/var/NFS 30G 6,7G 22G 24% / MNT

To disable this file system, it is enough to use the standard UMOUNT:

sudo umount / MNT /

findings

In this article, the NFS Ubuntu 16.04 setting was considered, as you can see, everything is done very simply and transparently. Connecting NFS Balls is performed in several clicks using standard teams, And the opening of the NFS balls in Ubuntu 16.04 is not much more complicated. If you have any questions, write in the comments!
