How many background traffic and event. how to prevent it it?

Postby rin67630 » 2019-07-27 21:44

Hi,
I am planning an IoT project with Debian Buster.
It will FTP once an hour to a server and resync time from NTP once a day. Just that.

The metered LTE connection is very restrictive so I must avoid unexpected background traffic.
Must I fear some background traffic from Debian and if yes, how can I prevent it?

If someone has got experience with NB-IoT connections using something like [url]1nce.com[/url] I would appreciate any clue!
Thanks

If you will not install unattended-upgrades, you should have not extra traffic, in my opinion.
These upgrades will be quite small in IoT device, I think, so I recommend to use them...

Indeed Debian does not generate background traffic other than NTP.
But the router does!
Anyhow that one is internal and will not affect the metered connection.

If you have the GNOME desktop installed then the gnome-software package can download updates automatically and I think there's a systemd timer that checks for updates every day:
Code: Select all
systemctl list-timers
