Complete SBC and ODROID newbie, and Linux ignoramus into the bargain

release version: 0.4 (build: beta-20141216)
I'm using - or trying to - Minidlna (aka ReadyMedia) running on my NAS as my media server. In my NAS's web interface/gui -> NFS Server page I have set up RuneAudio running on my ODROID-C1+ to have "full access" to my minidlna-share on the NAS. RuneAudio is identified on my NAS by its IPS address (and in the RuneAudio gui I've named it "rune").
But when under <NAS MOUNTS> I try to mount it I continually get error messages, no matter how many varying syntaxes for IP address and remote directory I experiment with. Clearly my ignorance of Linux is causing me to get something very basic wrong.
Here's the url for my debug info:-

I hope someone can pinpoint what I've done wrong or not done what I should have, and set me on the right path.
