I am interested in becoming proficient in Linux system administration. The question is, where do I start? My educational background lies in automated control systems engineering, but I have no work experience yet. I have a basic understanding of IP/TCP UDP HTTP protocols, network topologies, and I have completed several projects in PHP and Java.

Embrace the console fully, abandoning the GUI to its maximum extent. The console is not just a tool, it is your loyal companion and partner in crime. Let us delve into the realm of Bash, where all file manipulations can be executed effortlessly through the command line.

As you embark on this journey, equip yourself with the knowledge of Vim or Nano editors. Remember, practice is key in any learning endeavor. Take the leap and deploy a variety of servers - DNS, ftp, mailers, and application servers such as Apache, Tomcat, Wildfly, and Nginx. Explore the realms of OpenVPN and XMPP.

Create a local network of virtual machines if possible, and if you dare, venture into the realm of physical infrastructure. Dabble in smb and ssh to expand your horizon.

Furthermore, acquaint yourself with LDAP for comprehensive understanding. Do not overlook databases and their administration, as they are valuable assets in your arsenal. For additional expertise, try your hand at deploying and configuring TeamCity, GitLab, and RedMine. And do not forget Docker, as it holds immense potential for automation.

And there's more to come. Python awaits as the next step in your journey towards automation. And in the future, clusters may come your way, requiring your expertise.

Keep expanding your knowledge of networks through books, articles, and magazines. The quest for knowledge knows no bounds.

I dedicated a significant amount of time to self-study, ultimately becoming a Linux administrator.
However, I am contemplating a transition towards interface design or front-end development. The reasons behind this decision are manifold. First and foremost, the demanding nature of server management often disrupts sleep and makes it difficult to enjoy a well-deserved vacation. The expectation of being available at all times, even during holidays, can further exacerbate this issue. Additionally, there is a sense of despondency that arises from a lack of tangible output. While automation tasks may be resolved within a matter of days, the remaining time is often spent idling away with little to do.

It is natural to seek new challenges and explore different fields within the realm of technology. Interface design and front-end development offer unique opportunities for creativity and visual expression. By transitioning to these areas, you can embark on a path that allows for more tangible and immediate outcomes, while still utilizing the technical skills and knowledge you have acquired as a Linux administrator. So, it's perfectly understandable and commendable to consider diversifying your expertise and pursuing a career that aligns better with your passions and aspirations.

Here's a rough outline for your plan:
1. Install the latest version of Debian Linux, preferably without a graphical user interface.
2. Begin by reading a couple of books that focus on Linux, its command line, and general concepts. I recommend "Linux Pocket Guide" by Scott Granneman.
3. Practice and experiment with various commands and tasks, utilizing online resources like Google for guidance.
4. Configure internet connectivity and other related settings through the command line. This process will help you gain valuable knowledge, especially by exploring the extensive "man" help documentation.
5. ?? (Additional steps or tasks can be added here for further learning and exploration.)
6. Eventually, you'll be ready to delve into more advanced topics and dive into Linux administration literature.

Now, let's discuss Linux administration in a more serious manner. When we refer to Linux administration, it encompasses a wide range of responsibilities and possibilities. Linux allows you to set up various services such as web servers, DNS servers, and even an Active Directory (AD) domain controller. Exploring and explaining this vast topic can be challenging due to its breadth and depth. However, it's important to note that Linux administration offers immense potential for building and managing robust infrastructures tailored to specific needs and requirements. Embracing this discipline opens doors to endless opportunities and the ability to shape and maintain complex systems efficiently.
