mount permission denied though server side already authenticated the request

[Strong Qu]

I'm new of using busybox. Detail as follow:

ARM V6 platform Linux 2.6.10, Busybox 1.01, ash shell, server side is
Ubuntu 6.10, nfs exports *(rw, all_squash)

On target platform run:

# mount -o nolock 192.168.1.2:/home/user_1/share /mnt/shannon

Root has read/write/exec right in /mnt/pool. 192.168.1.2 is IP of
shannon, the nfs server.

I got error as:

mount: permission denied. (are you root?)

On the server side I run:

# tail -f /var/log/syslog

It shows:

Mar 30 11:01:13 shannon mounted[4330]: authenticated mount from
192.168.1.3 for /home/user_1/share (/home/user_1/share)

And on other x86/linux I can mount the nfs without any trouble.

I did not find nfsmount on the target board. Is it a must for nfs mount?

Thanks.
