There are two nfs servers in th funplug. One, the kernel nfs (nfsd), needs a kernel module. So I didn't test it yet. The second runs completly in user space, so no kernel module is needed and the usage is simple.

Connect to the device as a root. You can use the original telnet, or ssh if you configure it.

No you have to check if there is exports in /ffp/etc directory. I can be here from your previous experiments with nfs if there were some. So backup or simply remove that file. Now start the user space nfs server.

# sh /ffp/start/unfsd.sh start

When you start unfsd for the first time, it creates exports file. Now look in that file and modify it to meet your needs. Now your nfs server is running, but not scheduled to run after restarting on device. To do so we need to execute command

# chmod a+x /ffp/start/unfsd.sh

If you modify /ffp/etc/exports file, you need to restart the nfs server. Or your changes are not recognized until restarting your device. So run the command

# /ffp/start/unfsd.sh restart

Now, on your main computer, look what's really published from your nas device.

my-computer # showmount -e nas1
Export list for nas1:
/mnt/HD_a2 172.31.1.8
