Yes true sorry, soo i get this :

Error: <Wired connection 1> - no such connection profile.

You're good to go!
EDIT: So now the DHCP lease wont expire after 12 or 24 hours or so.

No tutorials.
Just trial and error plus the man pages:

man nmtui

man nmcli

28

Yep, normally all is okey, i will see this morning if my pi crash again or not with my box dhcp disabled and pi hole dhcp enabled

I didn't even knew that we could see manual of commands with man command, thanks, i start to love linux again after 3 years of not using it

Don't you think that i should disbale wifi on my pi hole ? Since i use ethernet only, or should i leave it lile that ?

31

I didnt know that lo is also a profile.
So that means I should change the command into:

nmcli -t -f name con show --active | xargs -n 1 nmcli -f ipv4.method con show

But cant test :wink:

32

Yes disable.

33

Same, why its not wlan0 ? On pc builds it was always wlan0

34

Below one shows names for interfaces detected by the kernel:

ip -br l

35

Also see:

man systemd.net-naming-scheme

36

Wait what's lo is for then since i have eth0, wlan0 and lo, for wlan0 it says down while when i use sudo nmtui i can see the list of wifi networks even if im not connected to any of them

Btw disabling wifi and bt is done with : sudo nano /boot/firmware/config.txt then we should add these two lines:
dtoverlay=disable-wifi
dtoverlay=disable-bt

Just as long as the wlan0 interface doesnt try to acquire an IP via DHCP.
Or else you get messages in Pi-hole that a hostname failed to register bc the name is already registered from the /etc/hosts file.

$ man dnsmasq
[..]
       -h, --no-hosts
              Don't read the hostnames in /etc/hosts.
