Ok, I helped myself and I got UNSF3 an non Kernel-Based NFS solution working on the LS Pro Duo.
Let me describe what I did:
1.) Enable telnet on your LS Pro (how to can be found in the forum)
2.) Install addons.tar (wget) on LS Pro Duo (how to can be found in the forum)
3.) Bootstrap the LS Pro Duo. See http://buffalo.nas-central.org/forums/viewtopic.php?f=19&t=4075&p=39162#p39162
I used the file "teraprov2-bootstrap_1.2-4_arm.xsh" for bootstrapping the LS Pro Duo
4.) Enter "ipkg update" to get latest ipkg packages list
5.) Enter "ipkg install portmap" to install a portmapper
6.) Enter "ipkg install unfs3" to install the user space NFS driver
7.) - open "/etc/exports" in vi : "vi /etc/exports" to add your shares that should be available via NFS
- Press "i" for insert and then add your directory for sharing via NFS:
eg.: /mnt/array1/nfsshare (rw,no_root_squash)
- Press Esc; then wq + Enter to save file
8.) Enter "/opt/etc/init.d/S55portmap" to restart the portmapper
9.) Enter "/opt/etc/init.d/S56unfsd" to restart UNFS3 - this is necessary to get the changes you made in /etc/exports
When you make changes in /etc/exports you always need to restart the unfs3 with "/opt/etc/init.d/S56unfsd".
10.) Be happy to access your files via NFS eg. on linux with the following command:
- mkdir -p /mnt/lspronfs (create mount point)
- mount -o vers=3,tcp,nolock,intr 192.168.1.xx:/mnt/array1/nfsshare /mnt/lspronfs
Some of the paths are only exmaples. You must replace them with your own values and .xx with the IP of you LS Pro Duo.
For more information you should have a look to the following URL that I used for reference: http://www.nslu2-linux.org/wiki/Optware/Unfs3
When you restart your LS Pro Duo then NFS will automatically start again.
