Amitcp's ncftp client and the proftpd server on the linux side works well i use that here, there could be compatibility issues with some servers. Using a 3com 3c589c, you will have to alter a configuration file in amitcp for it to work but it does. ( IE. tell amitcp you have the first NIC on the list, find the file in amitcp: containing the network adapter name and driver, replace the driver part with the correct 3com driver. )
