.H2 "NFS"
As with most Internet services, there are two halves to NFS:
.Ls B
.LI
.X "NFS client"
.X "client, NFS"
When you mount a file system from another system on your system, your system is
an \fINFS Client\fP.
.LI
.X "NFS server"
.X "server, NFS"
When another system mounts one of your system's file system, your system is an
\fINFS Server\fP.
.Le
.X "/etc/rc.conf"
A system can, and often does, perform both of these functions at the same time.
A certain amount of setup is required, however.  We'll look at both in more
detail in the following sections, but the simple answer is: 
.File /etc/rc.conf
does it for you.  We'll look at
.File /etc/rc.conf
in much more detail in
.Sref "\*[chconfigfiles]" ,
on page
.Sref \*[nfs-setup] .
For the present, just set these two lines:
.Dx
nfs_client_enable="YES"         # This host is an NFS client (or NO).
nfs_server_enable="YES"         # This host is an NFS server (or NO).
.De
There are also a few other NFS-related flags you can put in 
.File /etc/rc.conf .
We'll look at them later.
