What is a Network Engineer? Skills, Duties & Career

First off, it’s becoming more and more apparent that most network operating systems are based on some variation of Linux. Different vendors offer varying degrees of access to the underlying Linux operating system with the trend being to give the user more and more access into system internals. A lot of network operating systems are based on Linux, or have a Linux shell you can access, or use Linux type commands. The author shows you an example using Cisco, Arista, and Cumulus Linux.

Adding those components to run Linux distros on Android devices is pretty straightforward. Likewise, companies with multiple products using the Linux kernel can often merge functionality. Google, in particular, has often done so with its Android and ChromeOS projects. The company is integrating their build of the Android and ChromeOS Linux kernels more tightly to leverage their work on AI. In addition to the native Linux features, there are other projects such as Open vSwitch (OVS)that seek to extend Linux networking functionality.

The list will keep expanding, but for now let’s discuss how you can get your hands on a Linux box with as little cost as possible. There are a few free options if you are comfortable with working on the cloud. All major cloud providers (AWS, Azure, GCloud) have some free offering which allows you to spin a Linux host. The drawback is that all of those offerings have an expiration date, so you won’t be able to use them in the long term. Out of the box, you won’t have any issues configuring basic network settings through YaST (Yet another Setup Tool). Many of the packages that come preinstalled with openSUSE can provide you with incredible utility.

What is a DevOps Engineer? Roles, Skills, and Career Path

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. Network Administrators are essential personnel in any organization that relies on computer networks.

• Linux is renowned for its security and stability, which are critical attributes for network environments.
• 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.
• Embracing Linux and building expertise in this area is a strategic move for anyone looking to succeed in the field of network engineering.
• Most businesses store its data in cloud systems as these systems offer excellent security and scalability compared to traditional networks.
• Linux is responsible for some of the most advanced tools in the industry and creates opportunities for industry leaders to create incredibly powerful networks.

Labs, periodic Master Classes, and access to an Online Professional Community allow you to solidify your technical expertise. Embracing Linux and building expertise in this area is a strategic move for anyone looking to succeed in the field of network engineering. Work with other server administrators to help identify and refine minimums and maximum outputs.

As results, the router would return an ICMP packet with code “Can’t Fragment Error”, something that I found out with tcpdump. David has developed over 20 courses for HP which are used worldwide. These include multiple SDN courses and HP ASE certification courses (4 day Instructor led training). David’s software tools and training have been downloaded +100,000 times. Many thousands of engineers like you use his tools and training on a regular basis. Monitor Linux network usage and tailor parameters for optimum throughput.

Linux rose to fame on servers, and a network engineer’s use of the operating system will typically be within that domain. Some of the more common uses include the foundational elements of server management, monitoring network traffic, and investigating possible security issues. Much of this will be done with custom frontends that provide a more abstract view of the network and resource utilization.

Modern courses and learning activities in state-of-the-art technologies prepare you for your new career. For network engineers, understanding Linux is crucial for managing cloud infrastructure and integrating on-premises networks with cloud services. This community support is invaluable for network engineers, providing assistance and sharing knowledge about best practices, troubleshooting, and new developments. This ubiquity means that network engineers with Linux knowledge can work across a wide range of hardware and software platforms, making their skills highly transferable and valuable. In addition to these fixed salaries, network engineers can earn bonuses based on their performance or offer freelance services to diversify their portfolio.

Wicked is a powerful network configuration framework, for example, while Samba is perfect for enabling file-sharing between Linux and Windows systems. You won’t have any trouble installing the right tool for a job with openSUSE’s Zypper package manager. RHEL comes pre-equipped with the SELinux security module, so you will find it easy to get started with managing access controls and system policies.

Typically, a network engineer is a technology professional with linux network engineer the skills to plan, design, and implement complex network systems. End users typically need to know whether their hardware uses the Linux kernel. For example, Android phones use the Linux kernel but leave out many additional software pieces found in traditional distributions.

Network engineering is constantly evolving; sometimes, staying updated about the latest trends and technologies can become a hassle for engineers. They need to keep track of everything from new developments in network automation to cloud computing, which is quite overwhelming. Establishing secure systems is the ultimate responsibility of a network engineer. Firewalls scan different users and restrict access to users and computers showing suspicious activity.

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. Being a Linux engineer allows you to fully support and improve an organization while operating and troubleshooting multiple systems. Stressing the difference between Linux as a kernel and Linux distros might seem pedantic at first glance.
