Use vi editor to add the following text in the /etc/exports file.
The meaning of the text above is as follows.
The directory /nfs is to be shared through NFS and the host 192.168.10.0/24 can read and write
this /nfs directory without an authentication.
[192.168.10.x IP address ranges are all allowed]
Among parameters, rw and insecure have something to do with the authority to read and write a
file.
rw: r means read is allowed while
w means write is allowed
insecure: this means that authentication is not needed
[Note]
/nfs 192.168.10.0/24 (rw, insecure) means 192.168.10.x IP address range is all shared. Do the
following if you want to make your system information not exposed to the others or accessible
by specific host only.
Once done as above, only host 192.168.10.200 and 192.168.10.155 are allowed to read and
write without authentication.
