I've got a small home server running NFS and a couple of clients connecting to them. Currently the server is "secured" by sharing only to certain names/IP addresses, but when these machines are offline, someone else can easily take their place and get mount the volumes.

Thus - is there any mechanism in NFS that allows me do define a secret key or similar on the client and server to handshake before the client mounts the desired volume?

I know this is possible in Solaris' NIS+, but as there's no NIS+ for Linux (yet?) and that seems overkill, I was hoping a simple auth scheme would do it.

Thanks in advance for any insight.
