After I installed Ubuntu 8.04. I needed to mount NFS from my server but I could not mount because I did not install NFS client on by laptop so these are steps for mount NFS .
sudo apt-get install portmap nfs-common
and mount NFS from server by
sudo mount hostname://path/to/share /path/destination
such as
sudo mount 10.0.0.1://home/aoddy /media/test
