According to the manual, the MyBook supports both the CIFS/SMB and the NFS protocols.
CIFS/SMB is the protocol natively used by Windows for accessing network drives. You should be able to access the MyBook on a Linux/Unix system by using the smbclient or mount.cifs, e.g. to access (mount) the "public" folder on MyBook on the local directory
/mnt you would issue (from a
mount.cifs //ip.address.of.mybook/public /mnt -o username=admin,password=admin_passwd_on_mybook
mount -t cifs -o username=admin,password=... //ip.address.of.mybook/public /mnt
you can substitute "public" with "download" (to access the pre-defined download share) or any share name that you have created with the MyBook storage manager.
username/password can be those of any user that you have created on the MyBook storage manager interface; or just use
-o guest instead of
-o username=...,password=... to specify "Guest" access.
Access by the NFS protocol is not enabled by default; you have first to enable it in the "Advanced" tab of the MyBook storage manager, then you can mount the disk shares via NFS with:
mount -t nfs ip.address.of.mybook/nfs/public /mnt
Again, "public" can be any defined share name.
