How to Share NFS Files With Diffie-Hellman Authentication

This procedure protects shared file systems on an NFS server by requiring authentication for access.

Before You Begin

Diffie-Hellman public key authentication must be enabled on the network. To enable authentication on the network, complete How to Set Up a Diffie-Hellman Key for an NIS Host.

You must become an administrator who is assigned the System Management rights profile to perform this task. For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.2 .

1. On the NFS server, share a file system with Diffie-Hellman authentication.

   # share -F nfs -o sec=dh /filesystem

   where filesystem is the file system that is being shared.

   The –o sec=dh option means that AUTH_DH authentication is now required to access the file system.

2. On an NFS client, mount a file system with Diffie-Hellman authentication.

   # mount -F nfs -o sec=dh server:filesystem mount-point

   server

   Is the name of the system that is sharing filesystem

   filesystem

   Is the name of the file system that is being shared, such as opt

   mount-point

   Is the name of the mount point, such as /opt

   The –o sec=dh option mounts the file system with AUTH_DH authentication.
