If we consider that most network switches are built off of a Linux base, and provide similar functionality, the CLI becomes an abstraction of the underlying Linux system. While I think this is a fair generalization, it’s also fair to say that most vendors don’t run a completely vanilla version of Linux or the Linux kernel. One of the biggest challenges for Linux engineers is staying up-to-date with the ever-evolving technology.

This is a crucial network engineer skill that every aspirant should develop. These professionals are primarily tasked with the designing, building and managing of an organisation’s computer network. For instance local area networks (LANs) and Wide Area Networks (WANs) are a part of these computer networks..
What is a Linux Engineer?
Being a Linux engineer allows you to fully support and improve an organization while operating and troubleshooting multiple systems. Network Engineers often work in more senior or specialized roles, planning and implementing network systems. They typically handle higher-level tasks such as network architecture design, including Local Area Networks (LANs), Wide Area Networks (WANs), and cloud-based networks. Network engineers might also implement and manage firewalls, routers, and other network-related hardware.

Fedora also offers users an incredible arsenal of open-source tools, built-in support for containerized applications, and consistent access to cutting-edge features and software.
Job outlook and career growth
Another use case is testing whether your firewall is blocking certain traffic. For example, execute netcat in server mode on a host behind your firewall and then execute netcat in client mode from outside the firewall. If you can read on the server whatever you type on the client, then the firewall is not filtering the connection. Current trends are pushing the skillset of the network engineer and the server administrator closer together. On the physical network side, the ability to access the native Linux shell enables us to install tools and application once reserved for Linux servers. On the Linux server side, the days of simple host networking are quickly evaporating as more of the network logic moves down into the Linux host.
This guide will provide you with the information you need to navigate the Linux Engineer career path and achieve your professional goals. The role of a Linux engineer may vary depending on the organization but overall is the same. They’re typically more needed and involved within a tech company than other organizations. Those with Linux skills are sought after in the industry which is why Linux jobs are currently on the rise.
As Linux becomes an increasingly important part of modern technology infrastructure, the role of a Linux Engineer is becoming more and more critical. The career path of a Linux Engineer can be challenging but also rewarding. It includes a progression from Junior to Senior positions, and it is important to understand the different responsibilities and skills required at each stage.
Fedora is an open-source distribution that serves as a community equivalent to Red Hat Enterprise Linux (RHEL). RHEL itself is commonly chosen as the operating system for enterprise-level systems. To avoid future difficulties, you should test using software like Nmap on new Linux distributions and become familiar with networking. Among the well-known Linux distributions, Debian is famous for its excellent stability and high performance. Debian offers several forks, including Debian Stable (extremely secure and focused on stability) and Debian Unstable (more prone to problems but offering the latest cutting-edge software releases). Out of the box, with YaST (Yet another Setup Tool), you won’t have any problems configuring basic network settings.
Job growth for network engineering and administration in all technologies including Linux is expected to grow 4-5% in the next ten years.

When I was a computer science student I spent a lot of time playing around with Linux. My home network was routed by a Pentium 2 workstation running Slackware and configured with IP forwarding and IP tables. In 2003, I attended a CCNA boot camp; the other students and I practiced routing protocols (RIP and OSPF) by building an overlay point-to-point network between our houses. We used OpenVPN for the tunneling and then RIP and OSPF inside the tunnels. We help you gain critical insights and make more informed decisions across your business priorities. Overall, the salary for a Linux Engineer job can be quite competitive and offer good earning potential, especially for those with experience and specialized skills.
