NFS and RPC ports
 

Hi all.
I've got my PXE, NFS and TFTP server up and running and able to do a remote installation.
However, I felt I cheated a little bit, I used the system-config-nfs tool to set up the RPC ports. I was wondering where are these settings stored?
I know /etc/exports stores my location of the folder(s) to share
I just would like to know where the program puts all this RPC port info

I'm using Cent os 5.2

Many thanks
