The goal of this article is setting up a nfs-server for sharing files over a network. We'll keep it simple here, so everything should be pretty much understandable.
Required packages for both the server and the client are minimal. You'll only need to install:
Setting up the server
You need to have installed the nfs-utils package by now.
You should a few daemons (as root) to start the nfs-server:
/etc/rc.d/portmap start /etc/rc.d/nfslock start /etc/rc.d/nfsd start
You could add these daemons to the daemon-array in /etc/rc.conf to make them start on system-boot.
