nmtui if you’re using NetworkManager, Or edit the /etc/netplan/*.yaml if your install uses netplan.io.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I don't think it uses netplan.io - it is a very standard Debian server install - netplan.io being Canonical, I guess that would typically be found on Ubuntu installs?
nmtui sounds nice. I didn't end up installing NetworkManager now, but it is something I will look more into, so I've noted it down. Learning networks is a big goal for this year.
If it's a standard Debian install, look into /etc/network/interfaces .
If the wifi is configured in there, just replace the wifi interface name with that of your ethernet adapter, and delete the SSID and password lines.
But personally I'd use networkmanager and nmtui.
'ip a' to show your active addresses
rfkill to hard disable wireless devices
nmtui if you want a simple way to change network configuration or disable something
‘ip a’ to show your active addresses
Nice, now only my ethernet interface shows an IP after implementing the changes to etc/network/interfaces as described in an edit in the OP.
rfkill to hard disable wireless devices
rfkill was also not isntalled by default on my server, but I've installed it now and see that they (i.e. bluetooth and wifi) are unblocked, so I will now go learn how to block them. :)

Nice, I will check this out!
You might be able to prepare a bag accept that does the switch and run that inside a tmux session. The connection would get lost, but don't the tmux session did not care the script would finish. Although that would require to have the exact working commands. If anything goes wrong you would have to plug directly into the server.
All I ever used was nmcli and I think it should work for this purpose. It was mostly pre installed. Rasbien as well as Debian had it or installed (the most used distros by me).
tmux has been on my to-learn list forever now. Seems it should be bumped up in priority.
NetworkManager was not installed on my system, but I will look into this later and check out nmcli and nmtui (as suggested below) to get familiar with these tools.
Even if you do not use or like this approach, learning tmux is quite easy and quick and super useful. Just that you executed commands do not end when your ssh session crashes, that you can collaborate. Just attach multiple ssh sessions to one tmux session and everything, even the input, will be sync. In advance you get windows and split screen in any terminal.
That sounds awesome
