Setting up IP addresses
Server : 192.168.0.8
1. Install the nfs-kernel-server packet
I used synaptic package manager in Ubuntu 10.04 to install it.
2. Change /etc/exports file 
I also changed /etc/hosts.allow file for permission concern (I don't know whether it is necessary.)
3. Start nfs server
You might need to stop and start again if it's already running.
1. Mount from server
Files written into /mnt/synrg folder on the client machine will simultaneously transferred to the /home/synrg/server folder on the server machine.
