I am in no way and old hand at this, so you might want to sit this one out in the hope that someone more knowledgable than me answer you with a simpler solution, but..
Here is how I managed to set up my home network (the steps taking from my own notes)... it is not nearly as involved as the number of steps makes it out to be:
On both server and client:
1.Make sure all NFS related packages are installed (e.g. nfs-utils).
On the server, as root:
1.Edit /etc/exports. Insert the shared volumes/directories, e.g.:
Note: If root access is required, e.g. on /etc, add parameter 'no_root_squash'.
2.Edit /etc/host.deny. Insert line denials for all, e.g.:
3.Edit /etc/host.allow. Insert line allowals for the client(s), e.g.:
4.Make sure that service 'portmap' is running.
5.After setup, reboot. Command 'exportfs -ra' can also be used to read changes to /etc/exports.
6.Test that NFS is running and sharing, using 'rpcinfo -p'. This should give a list of deamons, at minimum portmapper.
On the client:
1.Test that NFS is running and sharing, using 'rpcinfo -p <IP_Address_of_Server>'. This should give a list of deamons, at minimum portmapper.
2.Insert a line in /etc/fstab for each share. I suggest only placeholders, i.e. 'noauto', e.g.:
192.168.1.102:/home/my-username /mnt/shared-partition nfs rw,soft,intr,noauto,noexec,nosuid 0 0
Note on write access: If UID and GUI is different from client to server, in '/etc/export', use '(rw,all_squash,anonuid=501,anongid=501)', changing the UID and GID as needed.
Info: portmapper uses port 111 default.
Feel free to ask... not sure I'll know the answer, and as said, maybe someone will be along with another approach.
