This article presents the methods for preparing a set of directories that can be exported to NFS clients using Linux. Under Linux this is can be accomplished by editing the /etc/exports file.
For the purpose of this example, I will be exporting (sharing) the directory /mnt/software.
The /etc/exports file contains an entry for each directory that can be exported to NFS clients. This file is read automatically by the exportfs command. If you change this file, you must run the exportfs command before the changes can affect the way the daemon operates.
Only when this file is present during system startup does the rc.nfs script execute the exportfs command and start the nfsd and mountd daemons.
Edit the exports file vi /etc/exports and add:
/dir/to/export is the directory you want to export
host#.mydomain.com is the machine allowed to log in this directory
The ro option mean mounting read-only
The root_squash option for not allowing root write access in this directory
For this change to take effect you will need to run the following command on your terminal:
How to export the the directory in read/write mode (not a good idea!):
