This is a guide on how to enable the NFS capabilities of the Synology product.
This procedure is aimed for users who are experienced with Telnet and the Linux Operating System
Please note that improper manipulation or modification of the Synology server may result in machine malfunction or loss of data.
Please read the General Disclaimer before modifying the Synology product.

Acquire Files

Please make sure that the Synology product has firmware 2.0.3 - 0518 or above, along with the Telnet service enabled.
Both files can be found here.


Instructions for the NFS Server

Telnet into the Synology product and perform the following

Enabling Service

cd /usr/syno/etc/rc.d
mv S83nfsd.sh.sample S83****.sh
reboot (or /usr/syno/etc/rc.d/S83****.sh start)
vi /etc/exports

Note: * needs to be replaced with a number

Exports file

In the exports file, add the following line 

/directory/to/export ip.of.NFS.client(ro,root_squash)

After saving the exports file, perform the following 

cd /
/usr/sbin/exportfs -a


Instructions for Linux NFS Client

On your NFS client, perform the following to mount the NFS Server share 

mount IP.of.NFS.Server:/directory/to/export /volume1/local/share/folder

Note: /volume1/local/share/folder must exist locally, otherwise the mount will fail


Windows Services for UNIX 3.5 Fast Setup Guide

Note: Originally written by forum user NetBoot
Note: Only Windows Vista Ultimate and Vista Enterprise Supports NFS Out of the Box by Installing Windows Components, Subsystem for UNIX-based Applications.

Note: For other NT-based Operating Systems, Windows 2000, Windows 2000 Server, Windows XP and Windows 2003 Server install the free Windows Services for UNIX 3.5



Download and install Windows Services for UNIX Version 3.5

The install defaults should be fine.
Complete the installation and reboot.

Telnet to your Syno box. We will need a copy of the passwd and group files located in the /etc
Copy the files to a secure directory using the cp command and change the permissions with chmod.

cp /etc/passwd /volume1/secure/passwd
cp /etc/group /volume1/secure/group
chmod 777 /volume1/secure/passwd
chmod 777 /volume1/secure/group

Next, copy passwd and group files to C:\SFU\common\ directory
Security Note: You may want to consider removing the root accounts from those files

Next, go into you Programs Menu/Windows Services for Unix and start Services for UNIX Administration

Click on Services for UNIX[local]and select the Settings tab.
Computer name should be localhost

Next, in the tree tab, click on Client for NFS
The File Permissions and Performance default settings should be fine.
We may play with these settings later.

Next, in the tree tab, click on User Name Mapping.
In the Configuration tab, where going to use Password and Group files. So, click on that bullet.

Now we're going to select the password and group files that we copied over earlier.

Browse for the files and select passwd for Password file path and name.
Browse for the files and select group for Group file path and name.
You should now have C:\SFU\common\passwd and C:\SFU\common\group
Now, click on Apply

Now click on the Maps tab.
We're going to do simple maps. So, check the simple maps box.
Since we are using simple maps. The Windows Domain Name should default to your computer name.
Now, click on Apply

Next, we're going to setup our permissions. Still in the Maps tab, under Advanced maps click on Show User Maps.
Under Windows domain Name click List Windows Users to fetch the Windows users. Next, click on the List UNIX Users to fetch your UNIX users. We're going to map our user account.
Click your windows user name to the left, and your UNIX user name to the right, and click Add.
You should now have a Mapped user account.
Click the Apply.

Now telnet to your Syno box and edit the exports file.
Here's a quick sample to get you going 

/volume1/nfs/public 192.168.0.0/255.255.255.0(ro,no_root_squash,no_subtree_check)

Your subnet may be different then mine, so adjust for yours.

Happy NFS serving,

Net....


P.S. This is just a fastpace setup. Other may find it better to add the UID and GID with the exports.
NFS and Samba: I would strongly suggest users create a directory for NFS and not use your Samba shares for NFS together. I would create a nfs directory off root and setup your NFS shares there and map your exports in there. ie: /volume1/nfs/public I'm sure there would be file lock issues,etc. Maybe someone who is an expert in NFS and Sambe can verify this.

Notes

The NFS Service is disabled after every firmware upgrade.
Files saved on the Synology server are case-insensitive.
Supported versions:

NFS 2.0
NFS 3.0
