mount: mount to NFS server '192.168.8.15' failed: RPC Error: Program not registered.

[laksh]

Hi

Need help in mounting the nfs file server.

In server 192.168.8.15
/etc/hosts.allow
ALL: 192.168.8.16/255.255.255.0

and in /etc/hosts.deny
portmap ALL
lockd: ALL
mountd: ALL
rquotad: ALL
statd: ALL

and in /etc/exports
/stage 192.168.8.16/255.255.255.0(rw,insecure,sync,insecure_locks,no_r oot_squash)

and in the client machine
/etc/fstab
192.168.8.15:/stage /mnt/stage nfs noauto,rw,user 0 0

but when I run the command
mount /mnt/stage I got the below error
mount: mount to NFS server '192.168.8.15' failed: RPC Error: Program not registered.

please let me know how to resolve this
