I am now using DEBIAN_WDLXTV_LIVE-0.2.2.1 as well, and installed this:
# apt-get install nfs-kernel-server nfs-common portmap
Then saved the following in /conf/exports (WDTV-Live with IP of 192.168.0.88):
And in my net.mounts (WDTV with IP of 192.168.0.66):
xmount 192.168.0.88:/live-media Live nfs
I think my net.mounts file is fine, as I can see my nfs shares from the ubuntu computer fine (defined similar to the xmount above).
Rebooted both, and got nothing. I am very new to Linux, so go ahead an jab at me if I did something stupid, as long as you relay some tips as well. Thanks.
