The following configuration disables root logins on the remote machine. Only users belonging to the group ssh-users may establish a connection. Access to the remote machine is tied to the local user’s private key.
In this example, the name of the remote machine is debian-server, which has the address 192.168.1.10 on the network. sid is a user on debian-server, whereas bookworm is a user on the local machine. Choose an encryption passphrase to secure the private key that you will generate in Step 5.
On the remote machine
Install the secure shell server with the following command:
$ sudo apt install --yes openssh-server
If you are using ufw as a host-based firewall
Configure ufw to allow connections to the secure shell server.
$ sudo ufw limit ssh
If you are using firewalld as a host-based firewall
Configure firewalld to allow connections to the secure shell server.
When prompted to confirm the authenticity of the host debian-server, type yes and press [Enter].
The authenticity of host 'debian-server (192.168.1.10)' can't be established.
ED25519 key fingerprint is SHA256:C9RxLLVbvFwVJc0L4JHzcuHQSaPHJZe/GrRDvqy6rAG.
This key is not known by any other names.
Are you sure you want to continue connecting (yes/no/[fingerprint])?
In the next step, enter the passphrase for your private key.
Enter passphrase for key '/home/bookworm/.ssh/id_ed25519-debian-server':
On the remote machine, download a file to harden the ssh server. You are encouraged to inspect its contents.
In the absence of an official client from Microsoft, the OneDrive Client for Linux connects your Debian or Ubuntu system to OneDrive Personal, OneDrive for Business, OneDrive for Office365, Sharepoint and other such deployments.

Currently available Espanso packages fail to install on Debian 12 because of unmet dependencies. Given that I depend on Espanso to expand text shortcuts and insert special characters, I was stuck on Debian 11. Until now!
The following instructions have also been tested with Debian 11.
After completing the installation, Espanso 2.2.0 for Wayland will be installed on your system and enabled for the current user.
nullmailer can be configured to use Fastmail as a smarthost and hence ensure the deliverability of your messages. In principle, these instructions should also be applicable to service providers other than Fastmail.
In the following example configuration, debian is the hostname, bookworm the local username and firstname.lastname@example.org the Fastmail username.
The usefulness of this project cannot be overstated.
Running the Syncthing stable channel
Syncthing is included in the Debian and Ubuntu repositories, respectively. These instructions are targeting the latest release of the Syncthing stable channel. It is therefore necessary to add the Syncthing repository to your list of APT sources.
In the following example, bookworm is the local username.
Add the Syncthing release key for validation of packages downloaded from the Syncthing repository.
By default, the Cockpit web console listens on port 9090 for connections. If you want to make changes from the default, use the following command to edit /etc/systemd/system/cockpit.socket.d/override.conf.
$ sudo systemctl edit cockpit.socket
The example below changes the web console port from 9090 to 9091 and restricts access to the localhost.

Debian GNU/Linux was first released in 1993 and has been under active developement ever since. Today, the Debian Project unites thousands of contributors from across the globe with the aim of producing “an operating system distribution that is composed entirely of free software”.
This guide is intended to assist those who are installing Debian for the first time. It offers a straightforward path to a GNOME desktop, albeit one with a smaller set of applications compared to the default. There are over 60000 official packages available for you to choose from and tailor Debian to your personal requirements.
Debian and the new package formats
Debian stable is, above all else, focused on the task of maintaining bug-free software packages. It is the reason why Debian, in over 30 years, has gained a reputation for being “like a rock in an ever-swirling sea of updates”. It is also the reason why Debian stable can never keep up with the latest versions.
Universal package formats, such as Flatpak, Snap or AppImage, are managed separately from conventional packaging systems and thus provide the end-user with added flexibility and choice. They solve the problem of stale distribution packages because newer versions can be installed without compromising the integrity of the underlying operating system.
Before you begin
In addition to a target computer, you need a reasonably fast connection to the Internet, preferably an Ethernet connection to your router and a bootable Debian CD image. If your laptop does not have an Ethernet port, consider using the Plugable USB 3.0 Gigabit Ethernet Adapter.
Depending on your acutal requirements, there are different Debian CD images to choose from. In all likelihood, you are following these instructions to install on x86-64 hardware, for which the debian-12.1.0-amd64-netinst.iso would be the correct choice. It supports Intel as well as AMD processors and “includes non-free firmware for extra support for some awkward hardware”.
After completing the installation, Debian GNU/Linux will be the only operating system on your computer.
Choose a hostname and a username for your setup. In the examples which follow, debian is used as the hostname and bookworm as the username. Just remember to make the substitutions when executing commands that reference either. Choose 1) an encryption passphrase to encrypt your storage device, 2) a user password to secure your user account, and 3) a root password to secure the root account.
Ensure that all of your data is safely backed up because formatting your storage device will erase all of its data.
Installing Debian GNU/Linux
If your computer uses the Unified Extensible Firmware Interface (UEFI) and you are unsure about which settings to use, you may wish to disable the Secure Boot option.
After booting the system from the USB stick that you have prepared, continue by selecting the text based installer.
Keep English as the language for the installation.
[!!] Select a language
Keep United States as the location for your system. This will also set United States as the default locale for the system environment. You will have an opportunity to set additional locales and adjust time zones at a later point during the installation.
[!!] Select your location
Country, territory or area: United States
Use the keymap that is the correct one for your particular keyboard.
[!!] Configure the keyboard
Keymap to use: your keyboard
You will likely be asked to select the primary network interface for use during the installation. If network autoconfiguration fails, go back to try another network interface.
[!!] Configure the network
Network configuration method:
Retry network autoconfiguration
Retry network autoconfiguration with a DHCP hostname
Configure network manually
Do not configure the network at this time
Set the hostname for your system. In this example, we use debian as the hostname.
[!] Configure the network
Select Show Applications from the the panel at the bottom of the screen or press [Super + a] and open the Settings application. On most keyboards, the [Super] key is the one with the Windows logo printed on it. Continue by adding the following keyboard shortcuts:
From within the GNOME desktop, open Firefox ESR by using the shortcut [Super + b] and re-open these instructions at edafe.de/step25.
Open a terminal with the shortcut [Super + t] and, where applicable, use copy and paste to enter the commands set out on this page. Be careful not to miss any punctuation.
Set the time zone for your area.
$ sudo dpkg-reconfigure tzdata
Geographic area: your area
Configure locales for all the languages that your system is going to be used with. Use UTF-8 locales wherever possible.
$ sudo dpkg-reconfigure locales
In this example, German and Japanese locales are generated in addition to the default locale for the system environment.
Locales to be generated:
[*] de_DE.UTF-8 UTF-8
[*] en_US.UTF-8 UTF-8
[*] ja_JP.UTF-8 UTF-8
Keep en_US.UTF-8 as the default locale for the system environment.
Default locale for the system environment:
The Desktop was disabled in GNOME 3.28. This decision was not universally popular at the time. However, developers pointed to the fact that, as an unmaintained feature, it stood in the way of other improvements. The following command hides the now orphaned Desktop folder from view.
$ echo Desktop >> ~/.hidden
Install additonal Debian packages to give you a functional GNOME desktop.
By default, Debian installs the Extended Support Release (ESR) version of Firefox. The ESR receives crash fixes, security fixes and policy updates as needed. The flatpak, on the other hand, installs the Rapid Release version of Firefox. In contrast to the ESR, the Rapid Release receives major updates at least every four weeks. Both versions can be used concurrently and are available on your desktop as Firefox ESR and Firefox Web Browser, respectively.
Set Firefox Rapid Release as the default browser.
$ xdg-settings set default-web-browser org.mozilla.firefox.desktop
Consider using different themes to easily distinguish between the two versions.
My favourite Desktop is Unity because it is not MATE. This has been bugging me for quite some time. Like almost everyone else on the planet, I was unhappy when in 2011 Canonical declared Unity Ubuntu’s new default desktop. After years of using GNOME 2, I just thought that Unity felt a bit awkward. But I stuck with it, mainly for a perceived lack of alternatives and my wish to avoid PPAs if at all possible. Fast-forward a few years and, thanks to the excellent Martin Wimpress, I hear of MATE Desktop Environment almost every other podcast I listen to. With the release of Ubuntu 15.10, MATE is finally elevated to official flavour status and I was sure to be making the switch away from Unity. I ended up using MATE for about one day before going back to Unity. It was quite an uncomfortable thing to have to admit, but there was a problem: After years of using Unity, I just thought that MATE felt a bit awkward… ubuntu-mate.org

With the eyeD3 command you can easily set the compilation tag for compatibility of your MP3 files with Apple gear. Just change to the directory containing the files making up the compilation (or soundtrack) and execute the following command:
“When the N9, running MeeGo received the strongest positive reviews of any Nokia phone ever, the first handset of any brand considered better than the iPhone—what did Elop do? He said that no matter how well the N9 sold, Elop would never allow another MeeGo based device to be sold by Nokia.” Microsoft has just bought Nokia’s handset division for a knockdown price of 5.3 Billion Euros, prompting former Nokia employee Tomi Ahonen to chronicle the decline of this once mighty company since in September 2010 former Microsoft employee Steven Elop became the first non-Finnish director in Nokia’s history. communities-dominate.blogs.com
“We wanted the book to be freely available (that is under the terms of a license compatible with the Debian Free Software Guidelines of course). There was a condition though: a liberation fund had to be completed to ensure we had a decent compensation for the work that the book represents. This fund reached its target of €25K in April 2012.” Raphaël Hertzog and Roland Mas hope that you will enjoy the book. debian-handbook.info
