DSM-G600, DNS-3xx and NSA-220 Hack Forum

Hi guys, very long time i don't post here 
After some years i found in a corner my g600, and i decided to try to give it a new life ^_^
I bought an ide/sata adapter, and now i use it with a 1tb sata disk. The disk works well, even if sometimes it try to spin down every 60sec...but the real problem is that i cannot access from the network by my linux pcs.
I have a raspi clone with ubuntu 16, and it doen't access to all the network when the dsm is powered on, and i have a mint 18 pc which see the network, but cannot access to the g600. And my old laptop with mint 13 access without problems O_o.
I think it is a samba 4 trouble, but i haven't found a solution.
This is very noisy, coz i've attacched a 500gb sata disk to one usb port, and a 320gb sata disk to the other, and it is very frustrating to have access only from my old xp/mint13 laptop.
Have you encountered similar issues?
Suggestions will be very appreciated
Thanks a lot
