NFS (Network File System) is basically developed for sharing of files and folders between Linux/Unix systems by Sun Microsystems in 1980. It allows you to mount your local file systems over a network and remote hosts to interact with them as they are mounted locally on the same system.
What is NFS configuration file?
This file contains site-specific configuration for various NFS daemons and other processes. Most configuration can also be passed to processes via command line arguments, but it can be more convenient to have a central file. In particular, this encourages consistent configuration across different processes.
Which file is used in NFS server configuration?
The new configuration is written to /etc/exports. The NFS Server Configuration Tool reads and writes directly to the /etc/exports configuration file.
What is NFS and how it works?
Network File System (NFS) Protocol
NFS, or Network File System, was designed in 1984 by Sun Microsystems. This distributed file system protocol allows a user on a client computer to access files over a network in the same way they would access a local storage file.
Where is NFS conf?
Global configuration options are set in /etc/nfs. conf . Users of simple configurations should not need to edit this file. The NFS server needs a list of exports (see exports(5) for details) which are defined in /etc/exports or /etc/exports.
Which is better SMB or NFS?
NFS offers better performance and is unbeatable if the files are medium-sized or small. For larger files, the timings of both methods are almost the same. In the case of sequential read, the performance of NFS and SMB are almost the same when using plain text. However, with encryption, NFS is better than SMB.
What is NFS vs SMB?
NFS is used for server to server file sharing and is mostly a server-client file-sharing protocol. SMB is used for the transfer of files from the places the user needs and is mostly a user client file-sharing protocol. NFS requires AppleDouble files to share Apple extended documents.
How does NFS work in Linux?
Network File Sharing (NFS) is a protocol that allows you to share directories and files with other Linux clients over a network. Shared directories are typically created on a file server, running the NFS server component. Users add files to them, which are then shared with other users who have access to the folder.
How do I use Showmount in Linux?
showmount command shows information about an NFS server. This information is maintained by the mountd server on the host. The default value for the host is the value returned by the hostname.
showmount Command Options.
|-d, –directories||List directories that have been remotely mounted by clients.|
How do I know if NFS is installed on Linux?
Verifying that NFS is running (Linux and UNIX)
- AIX® operating systems: Type the following command on each computer: lssrc -g nfs The Status field for NFS processes should indicate active . …
- Linux® operating systems: Type the following command on each computer: showmount -e hostname.
Is NFS safe?
Network File System protocol was created by Sun Microsystems in the 1980s as a file system for diskless clients. NFS provides remote access to shared file systems across networks. It was designed to be simple and efficient, not to be secure.
Where are NFS files stored?
Every filesystem being exported to remote users via NFS, as well as the access rights relating to those filesystems, is located in the /etc/exports file.
What is an NFS export?
NFS is the most common protocol for sharing files between Unix systems over a network. NFS servers export directories from their local hard disks to NFS clients, which mount them so that they can be accessed like any other directory.
How do I set up NFS?
Install the NFS Client on the Client Systems
- Step 1: Install the NFS-Common Package. As is the norm, begin by updating the system packages and repositories before anything else. …
- Step 2: Create an NFS Mount Point on Client. …
- Step 3: Mount NFS Share on Client System. …
- Step 4: Testing the NFS Share on Client System.
Does NFS use DNS?
Why does DNS & NFS use UDP? … DNS requests use UDP because the user will retry an operation if the DNS resolution fails. As another example, the Network File System (NFS), a remote file system application, performs recovery with application layer code, so UDP features are acceptable to NFS.”….
What port is NFS?
NFS uses port 2049. NFSv3 and NFSv2 use the portmapper service on TCP or UDP port 111. The portmapper service is consulted to get the port numbers for services used with NFSv3 or NFSv2 protocols such as mountd, statd, and nlm.
