Static IP address in Linux (Debian)

You can give your Debian installation a static IP address by following these steps:

1. Determine your network interface name: Use the following command to determine the name of your network interface:

ip addr

This will display information about all of your network interfaces. Look for the interface that you want to configure with a fixed IP address. The interface name will be listed on the left-hand side of the output (e.g. eth0, enp0s3, etc.)

2. Edit the network configuration file: Use a text editor to edit the /etc/network/interfaces file. For example, you can use the nano editor by running the following command:

sudo nano /etc/network/interfaces

3. Configure the network interface: Add the following lines to the file, replacing the interface name and IP address with your own values:

auto <interface-name>
iface <interface-name> inet static
address <ip-address>
netmask <subnet-mask>
gateway <default-gateway>
dns-nameservers <dns-server-ip-address>

For example, if your network interface name is “eth0” and you want to set the IP address to “192.168.0.10”, the subnet mask to “255.255.255.0”, the default gateway to “192.168.0.1”, and the DNS server to “8.8.8.8”, the configuration would look like this:

auto eth0
iface eth0 inet static
address 192.168.0.10
netmask 255.255.255.0
gateway 192.168.0.1
dns-nameservers 8.8.8.8

4. Save and close the file: Press Ctrl+O to save the file, and then press Ctrl+X to close the editor.

5. Restart the networking service: Use the following command to restart the networking service and apply the changes:

sudo systemctl restart networking

After you’ve completed these steps, your Debian installation should have a fixed IP address. You can verify the configuration by using the “ip addr” command again and looking for the interface that you configured.

Permanently switching off the GUI in Debian Linux

* Disable the Display Manager: The Display Manager is the graphical login screen that appears when you start up Debian. You can disable it by stopping the service and preventing it from starting at boot time. Use the following command to stop the service:

sudo systemctl stop display-manager.service

And then disable the service from starting at boot time:

sudo systemctl disable display-manager.service

* Remove the GUI packages: You can remove the GUI packages from your Debian installation by using the following command:

sudo apt-get remove task-gnome-desktop

This will remove the GNOME desktop environment and all its associated packages. If you’re using a different desktop environment, replace “gnome” with the name of your desktop environment.

* Reboot your system: Once you’ve disabled the Display Manager and removed the GUI packages, you’ll need to reboot your system for the changes to take effect. Use the following command to reboot your system:

sudo reboot

After the reboot, your Debian installation should boot into a command-line interface without any GUI.

Keep in mind that disabling the GUI permanently may make some tasks more difficult or time-consuming to perform. It’s recommended to proceed with caution and ensure that you have a backup plan in case you need to re-enable the GUI later.

The following has been suggested by https://fosstodon.org/@HankB :

Or

systemctl set-default multi-user.target

sudo systemctl set-default graphical.target

I have no idea why my fuse got bonked, but I simply made a folder named fuse in the dev folder and everything works as intended again.
