I am trying to mount one directory through nfs over iPV6.
OS : linux 2.4.20-8 (rh9)
The error message I get is,
[root@ipsec-host-251-132 home]# mount -t nfs
2002:: /mnt/nfs6
mount: RPC: Remote system error - Invalid argument

The same directroy gets mounted from IPV4.

[root@ipsec-host-251-132 home]# mount -t nfs
[root@ipsec-host-251-132 home]#

I have no idea what must be happening. Any pointers are welcome.
Thanks for your time,
