What Is Debian Linux?


Debian Linux is an operating system comprised of free and open-source software only, and all pieces pass a comprehensive testing procedure before becoming part of its distribution.

Debian stands out by being upgradeable, with developers regularly providing upgraded packages that users can install to upgrade their system.

It’s Free

Debian project software is free software, as outlined by its Social Contract and Debian Software Guidelines. Anyone may modify and redistribute it freely while also having access to its source code. Furthermore, Debian is unique among Linux distributions in that it uses a formal decision making structure instead of simply being run by volunteers; furthermore it tracks bugs and issues so it is easier for users to report issues directly with Debian itself.

Debian Linux is an extremely flexible operating system designed for desktop computers, servers and Internet of Things devices (IoT). It supports all major computer architectures including Intel 64-bit x86-64/i386 processors; Armada-based ARM; PowerPC processors; RISC processors as well as older hardware. Debian works equally well on new and legacy computer models.

Debian-based Linux distributions have long been among the most popular, including Ubuntu and Knoppix – two popular examples being originally based on Debian. Debian is an independent project run entirely by volunteers from around the globe; with a democratic decision-making process that gives each member equal say over how the project develops and its 29 year track record proving that it is a trustworthy organization.

Debian attracts many users due to its application software – programs to assist with everything from editing documents and running businesses, playing games and writing more software. Debian software package contains over 1500 packages or precompiled programs ready for installation on computers – all free. Furthermore, developers make adding other free programs simple.

Debian developers strive to meet a set of goals, yet sometimes this can be challenging. For example, new versions of applications must be included into Debian’s main branch for inclusion; otherwise, testers and unstable versions will have to wait before upgrading.

It’s Easy

Debian Linux operating system is one of the easiest Linux systems to set up. Perfect for purists who prefer an open-source approach to software development over proprietary, closed source solutions. Furthermore, Debian is very stable and secure; with an extensive user base ready to assist should any issues arise.

Security is of utmost importance in servers, and this operating system offers you a variety of customizable desktop environments like KDE, Xfce and Cinnamon for maximum desktop experience. In addition to that it comes equipped with numerous applications to assist with anything from word processing to video editing.

Debian stands out among competing operating systems by running seamlessly across a variety of hardware platforms. The OS can support Intel x86-64 processors as well as 32-bit ARM architecture – even on older hardware that cannot run more recent Windows versions.

Debian may have its quirks, but it remains an excellent operating system suitable for many different users. Installation should only take 10-15 minutes but please remember that its installer will wipe your hard drive – make sure you back up your data!

Debian website features a “download” button that will instantly install a minimal net install; however, this may not be the best way to get started as documentation can be lacking and difficult to follow – particularly with regard to installing non-free software.

Debian may not be as user-friendly as Ubuntu, but experienced Linux users will likely appreciate its flexibility. Debian differs from other distributions in that there is no fixed release schedule; updates come out when ready – which typically makes for longer release cycles compared to Ubuntu.

Debian systems tend to be more stable, making upgrades simpler, as well as being better at detecting dependencies and keeping files up-to-date, with Debian trying to eliminate bugs before releasing new versions.

It’s Stable

Debian is well known for being stable. Because it updates less often than other Linux distributions, Debian is less vulnerable to security vulnerabilities that affect other operating systems. Furthermore, developers implement an extensive testing procedure before considering software packages for inclusion in Debian stable releases, guaranteeing that any such program has been tested thoroughly before inclusion in that release.

Debian releases their stable versions every two or three years and boasts an extensive user base who provide feedback about the software. Debian developers use this information to make changes for future iterations of Debian OS; the process can often take years until new releases become stable.

Debian stands apart from most Linux distributions by including an extra repository offering newer versions of software packages than what are found in stable. This warehouse, known as Testing, serves to test out new software. When developers want to test out a new version of a package they upload it directly into Testing where it will become available to any stable distribution user. Once it has been in Testing for several days and fulfilled certain criteria (like no bugs filed with a specific priority) then its developer creates a.deb file and uploads it directly into unstable.

Debian provides many tools to make software installation and configuration simple and convenient, making it simple to select packages from different releases and easily mix and match packages across releases. However, it’s essential to understand their differences and how they all fit together – for instance if installing packages from unstable branches you could damage your stable operating system.

Debian is one of the world’s premier Linux distributions and has inspired various derivatives like Ubuntu and Knoppix. Debian is supported by thousands of programmers worldwide and continues to flourish today with strong future growth prospects.

It’s Secure

Debian stands out as both an affordable and secure operating system, thanks to being independent from one single entity – making it harder for malicious programs to attack it directly. Furthermore, Debian was designed from its inception with security as a top priority and many tools exist that help ensure its protection.

One of the best ways to protect a Debian GNU/Linux system is with a firewall. A firewall is a software program that blocks incoming traffic from accessing your computer and can block access for specific ports or protocols – useful in stopping hackers from attacking. A firewall can enhance security on both desktop computers as well as servers.

Installing the latest security updates is also key, as this can decrease the chance of hackers exploiting vulnerabilities in new versions of Debian software. Debian provides three release branches: stable, unstable and testing with each branch having its own schedule of updates – with stable receiving less frequent updates than its unstable or testing counterparts.

Debian systems can further increase their security by using secure shell. This will ensure you do not log in using public keys and thus reduce the chances of someone accessing your system using brute force attacks against its administrator account. It’s also wise to install Fail2ban which will block IP addresses that attempt to break in and block their attempts from accessing your machine.

Debian is an extremely secure operating system, yet not impervious to attacks. A system’s security can only ever be as good as the administrator makes it; that is why reading security guides and being mindful about what software you install on your computer are both vital steps towards keeping yourself protected from potential dangers. Joining a security mailing list also can provide invaluable updates regarding threats threatening it.
