I am running FreeBSD 9.0-RELEASE (64 bit), with a VirtualBox VM also
running the same.
On the host I am running NFS server:
$ showmount -e
Exports list on localhost:
/usr/home Everyone
But when I try to mount is on the client (the VM guest) I get this:
# mount xxxxxx:/usr/home /mnt
[tcp] xxxxxx:/usr/home: RPCPROG_MNT: RPC: Authentication error; why =
Client credential too weak
#
On the server, in /var/log/messages I see this:
mountd[29140]: mount request from nnn.nnn.nnn.nnn from unprivileged port
So I infer that the 'unprivileged port' bit is the problem.
Further information - on the client:

What am I doing wrong? I am new to NFS.
