DNS-321 Network Share copy files from NS1 to NS2
Conclusion 1:  It appears that the DNS-321 client FTP software can only transfer from one local DNS-321 to another local DNS-321.
An operation was attempted on something that was not a socket - FTP server stopped, go to menu, press start
503 Please Tell Me who you are - not logged in ?? - make sure the user has FTP access (to the root?)
sometimes the DNS-321 must be restarted to fully activate new settings
when the DNS-321 is restarted, the FTP server must be manually restarted.
