Ubuntu Linux: NFS Client Configuration To Mount NFS Share

NFS (Network File System) client allows you to access shared directory from Linux client. The computer sharing the directory is called the NFS server (it can be NAS server too) and the computers or devices connecting to that server are called clients. The clients need to use the mount command to access the shared directory.

Task: See The List Of All Shared Directories

Type the following command:
$ showmount -e server-Ip-address
$ showmount -e 192.168.1.1
Sample outputs from my 192.168.1.1 NFS server:

Export list for 192.168.1.1:
/viveks
/Web
/Usb
/Recordings
/Public
/Network Recycle Bin 1
/Multimedia
/Download

Task: Mount Shared Directory

Now mount /viveks directory as follows>:
$ sudo mkdir /nfs
$ sudo mount -o soft,intr,rsize=8192,wsize=8192 192.168.1.1:/viveks /nfs
$ df -h
Sample outputs:

Save and close the file.

How Do I Remove Mounted NFS Directory (unmount NFS)?
