This evening, while trying to figure out why my kid can't play Dragonvale over Wifi, I discovered that DDNS was enabled on my router -- i had one of those asuscomm domain names assigned to me. Worse, Samba was turned on. I have two USB drives where I sftp restic and duplicity backups from a number of machines -- the transit is encrypted, but the restic backups are not encrypted I think, but they are behind a password. (Not sure on the security details, what it means to have a password.) I guess I'm just trying to take the temperature of my malady -- is it possible those things are on by default? I'm whistling in the dark here, aren't I?
