My Setup:

NFS setup on RHEL5 to export user home directories for a cluster of servers. LDAP setup as the centralized directory service for user info and authentication using TLS/SSL encryption between the server and clients.

I want to encrypt the NFS data between the NFS server and the clients using SSH while using autofs to minimize network traffic. Does anyone know of a good how to for this setup or know how to do this themselves. I have found numerous detailed howtos for setting up NFS over SSH however they all setup the share for long periods of time. I have 17 servers I need to do this with and want to minimize having every server with a hard mount to NFS.

I am open to other suggestions if what I want is a pipe dream....

Thanks.
