Can I password protect an NFS share?

Question

I have two machines on a local network (Ubuntu 11.04). I created an NFS server on machine A. The other machine B receives its IP through DHCP.

I want to know if IP is the only way to allow or deny hosts from accessing the NFS share. Is there some way I can restrict access to the NFS share based on a password?

Answer 1

Without involving an authentication method like Kerberos, NFS on its own has very little in the way of access control - pretty much just restriction by IP address as you noted.

More info here if you want to look at the Kerberos option:
