If you only have Amigas on the network, you should really go for Envoy instead of Samba. Envoy was the 'official' Amiga filesharing system, and its dead easy to install and use. It'll share all your drives and printers to other Amigas.
I *think* its still available from Vesalia or Schatztruhe or so, but if you want to order it from your country, ask your local Amiga dealer. They may have old stock, or be able to import it for you.
