I didn't know that NAS means "Network Attached Storage".
Samba/CIFS works fine indeed. Under one's arm, it could be useful.

I use a open HTTP server with specified URL at lyokolux.space (with url sizes of 128 characters, try to brute force it ;). Useful when I want to share datas or specific ressources. I use however SSH when it's just for myself.
This system works fine until now.
