How do I change to NFS version 3 so that other UNIX variants may access my NFS share on my Fedora 17?

[Jerome Yanga]

The anonuid/anongid are valid UID/GID.

The nohide option didn't work.

Here is the logs from /var/log/messages of the Fedora machine while
the AIX machine performed a "ls".

Nov  8 09:44:31 fedora1 kernel: [515749.246015] device em1 entered
promiscuous mode
Nov  8 09:44:34 fedora1 rpc.mountd[28150]: authenticated mount request

Nov  8 09:44:37 fedora1 kernel: [515755.643377] device em1 left promiscuous mode

Here is the error I found from the network trace.
