Accessing/Mounting NFS shares

Hi

I have a Linux based NAS (Icy Box IB-4220-B), which supports sharing either Samba or NFS, obviously I'd rather not used Samba although simpler to implement.

I have tried:


and got:

I then tried using finder Go > Connect to Server, using:


And I get:


My OS X username and password are identical to the username and password on the NAS, the NFS shares have been set up wth the correct IP addresses for both my Macs.

I can't find /etc/fstab and don't know what to put in an new file.

Any help would be much appreciated.

Windows irony

Get this, I can access the NFS shares on my Windows test machine shares Microsoft Services for UNIX (SFU). I copied the /etc/groups and /etc/passwd files from the NAS so SFU would correctly map users and it works fine.

From OS X, I can access the Samba shares fine, so that proves the usernames and passwords are correct.
