NFS Checklist
Administrative Note

NFS Consists of the following:

/etc/exports
#/etc/exports contains all the NFS shares

/usr/sbin/exportfs -r
#exportfs -r is used to synchronize nfsd in memory with the /etc/exports file
#Use exportfs -v to see which shares nfsd is currently exporting

/etc/rc.d/init.d/nfslock - which has 2 parts
   /sbin/rpc.lockd
   /sbin/rpc.statd
/etc/rc.d/init.d/nfs - which has 3 parts
   /usr/sbin/rpc.rquotad
   /usr/sbin/rpc.mountd
   /usr/sbin/rpc.nfsd

At bare minimum you need to have portmap (or portmapper),
mountd (or rpc.mountd), and nfsd (or rpc.nfsd) running;
otherwise NFS isn't running.

#Sample nfs /etc/exports file:
/home/ftp/pub (ro,insecure,all_squash)
/home/ftp/pub adminsvr(rw,insecure,all_squash)

#Above we have two entries, one for everyone, and one
for the adminsvr machine.
