Network configuration when acessing Home Assistant OS via ssh

Installation Home Assistant OS
1

Hello,

I have been using Home Assistant for a few weeks and here is something that I do not understant.

Here is my set-up:

  • Home Assistant OS:
    • Home Assistant 2022.11.4
    • Supervisor 2022.10.2
    • Operating System 9.3
    • Frontend 20221108.0 - latest
  • Raspberry Pi 3.

Via the GUI, when I look at the network configuration, I see the IP adress for the Network interface is as I configured :

What I don’t understand is where does this eth0@if51 interface comes from when i connect in ssh:


| |  | |                          /\           (_)   | |            | |  
| |__| | ___  _ __ ___   ___     /  \   ___ ___ _ ___| |_ __ _ _ __ | |_ 
|  __  |/ _ \| '_ \ _ \ / _ \   / /\ \ / __/ __| / __| __/ _\ | '_ \| __|
| |  | | (_) | | | | | |  __/  / ____ \\__ \__ \ \__ \ || (_| | | | | |_ 
|_|  |_|\___/|_| |_| |_|\___| /_/    \_\___/___/_|___/\__\__,_|_| |_|\__|

Welcome to the Home Assistant command line.

What is this IP adress 172.30.33.255?
Why is it not 192.168.0.235 as I would expect?
Is there some kind of layer between the environment I am accessing via the GUI and the environment I am accessing via ssh?

Thank you!

You’re ssh’ing inside a docker container here, thru the SSH addon.
See Debugging the Home Assistant Operating System | Home Assistant Developer Docs (home-assistant.io) to ssh into the host.
