Network File System (NFS) (1984) is a distributed file system protocol that allow to share files and folders using a TCP network.


  • Ports: Port 111 (TCP and UDP) and 2049 (TCP and UDP) for the NFS server.


Installation[edit]

Linux commands[edit]

Example output NFS share to everyone: HOST#exportfs /nfs <world>

Windows commands[edit]

  • Get-WindowsFeature -Name NFS*
  • Install-WindowsFeature -Name NFS-Client
  • mount 192.168.0.1:/FOLDER_NAME n:
  • New-PSDrive -Name Z -PSProvider FileSystem -Root "\\192.168.0.251\FOLDER_NAME"[1]
    • Remove-PSDrive Z
  • New-PSDrive -Name K -PSProvider FileSystem -Root "\\ServerName\ShareName" -Persist -Scope Global[2]
  • New-PSDrive -Name K -PSProvider FileSystem -Root "\\ServerName\ShareName" -Persist -Credential $cre -Scope Global

See also: https://davidring.ie/2018/07/06/windows-2016-mount-an-nfs-share/

Configuration file: /etc/exports[edit]

/etc/exports [3]

Example: 

/export       192.168.1.0/24(rw,fsid=0,insecure,no_subtree_check,async)
/export/users 192.168.1.0/24(rw,nohide,insecure,no_subtree_check,async)
fsid=0 signals the NFS server that this export is the root.

Warning: /etc/exports is affected by adding additional space characters, be mindful about format

NFSv4[edit]

NFSv4 no longer utilizes the MOUNT protocol.

Linux Kernel[edit]

Related terms[edit]

Activities[edit]

Install server: apt-get install nfs-kernel-server
Install client (optional): apt-get install nfs-common
