I'm not sure about ntfs, I'll try tomorrow... Today I tried sharing my whole / folder, which works well, but the /mnt folder is empty, so it doesn't follow other partitions automatically. I'll try to mount the others separately, maybe it will work.
For the quick how-to:
1. Make sure the nfs daemon is running on both computers (activate in tasma-system).
2. On the server computer, edit /etc/exports
and add the line: / client_computer_name(rw,sync)
(make sure to change client_computer_name to the name of the computer that shall be allowed to mount the server's /
If you only want to share one folder, make the line something like: /home client_computer_name(rw,sync)
3. reboot (not sure if necessary)
4. Create a folder on the client computer where the other computer's fs shall be mounted (let's assume it's /server_name)
5. Open a console and become root (su root
6. Type mount server_computer_name:/ /server_name -o sync,hard,intr
(make sure to replace server_computer_name by the server's name, or you can also use the server's IP)
If only mounting a folder, use mount server_computer_name:/home /server_name -o sync,hard,intr
7. Now you can access the other computer's fs in /server_name as if it was local
The options sync, hard and intr should be used to avoid file corruption because of network connection failures. It's quicker without sync, but not recommanded!
You can automount on the client by adding a line to fstab but this will cause problems if the other computer is not available (boot process stops and hangs). So do not use on mobile computers like laptops.
All this I learned from: http://nfs.sourceforge.net/nfs-howto/
and especially from http://nfs.sourceforge.net/nfs-howto/ar01s03.html
I hope that helps for now....
