Re: Disable connections to Internet without user's consent

Unless you enable unattended upgrades explicitly (https://wiki.debian.org/UnattendedUpgrades) Debian wouldn't download them automatically.

Some tools may send multicast requests (I think Avahi does: https://wiki.debian.org/Avahi)

You can use `tcmpdump` to check all your Internet traffic, and then use `iptables` (or `nftables`) to disable unwanted traffic or simply uninstall software that does it.

Windows does a lot of things under the hood. Linux doesn't.

I wonder all the ways a standard installation and configuration connects
to the Internet without the user's consent, and how to disable it.

I can think of the automatic check for updates and the automatic
security updates.  Any other?  Is there a manual page that lists all of
them?
