Having a solid understanding of Linux as it relates to both basic operations and networking is a skill worth having. To avoid future difficulties, you should test using software like Nmap on new Linux distributions and become familiar with networking. One of the biggest advantages of using Debian for network engineering is that it has an incredibly package-rich repository, containing over 59,000 different packages. Among the well-known Linux distributions, Debian is famous for its excellent stability and high performance.
- The company is integrating their build of the Android and ChromeOS Linux kernels more tightly to leverage their work on AI.
- Learn how to configure Linux networking, how to create users and assign permissions, how to install and run Linux services such as DNS and DHCP.
- This article explores why Linux is crucial for network engineers, highlighting its key features, advantages, and the skills network engineers need to leverage its full potential.
- However, it’s also essential for network engineers to feel at home logging into a Linux server on the command line.
Cumulus Linux Fundamentals, plus Ansible automation
The kernel is licensed under the GNU General Public License, and most Linux distributions are either entirely or primarily open source. But in general, all of this means you’re free to modify, build upon, or even sell Linux. The ability to freely modify and distribute improvements is one of the most significant reasons for the operating system’s long-term success. People have been adding features they want into Linux for decades and integrating those changes into the larger codebase. In simplest terms, Linux is an operating system similar to what you’d find on a Windows machine, MacBook, or Chromebook. When people talk about Linux, they typically refer to the full collection of software packages and window managers known as a Linux distribution or distro.
Top 5 Linux Utilities for Network Engineers
I’ve used iperf many times to troubleshoot network slowness issues, verify whether the ISP would honor the DSCP marking, and measure the jitter value of UDP traffic. We have already written a post about using iperf in distributed monitoring, so I encourage you to read that if you want to learn more. For the routing process, we first used Zebra and then Quagga (which at the time supported OSPF).
John Breeden II is an award-winning journalist and reviewer with over 20 years of experience covering technology. Learn how mastering just a few basic skills can linux for network engineers advance your job and career. The range and scope of technologies that leverage Linux is large and growing rapidly. The deeper you dive into any technology the more likely you are to see Linux.
For network engineers, automation can simplify complex processes such as configuration management, network monitoring, and log analysis. Linux also supports a wide range of network protocols and can be used to simulate network environments, which is invaluable for testing and development. This article explores why Linux is crucial for network engineers, highlighting its key features, advantages, and the skills network engineers need to leverage its full potential. Im starting to look for network engineering jobs and alot of them are asking for linux experience. 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.
Embracing Linux and building expertise in this area is a strategic move for anyone looking to succeed in the field of network engineering. Knowledge of Linux is therefore essential for network engineers working in environments that adopt DevOps practices. Major cloud platforms like AWS, Google Cloud, and Azure offer extensive support for Linux, and many cloud-native applications are designed to run on Linux environments. Additionally, the stability of Linux ensures minimal downtime and consistent performance, which is crucial for maintaining reliable network services. Its robust security model, combined with the ability to quickly patch vulnerabilities, makes Linux a preferred choice for network systems that require high levels of protection. These tools are essential for tasks such as network configuration, monitoring, troubleshooting, and security enforcement.
The cause was that some traffic that used the entire IP payload without accounting for the IPSec header had the DF bit set. As results, the router would return an ICMP packet with code “Can’t Fragment Error”, something that I found out with tcpdump. Well, I think that having a basic knowledge of Linux is no longer just for students and computer geeks. Network engineers will often run into Linux-based network operating systems and command lines.

O’Reilly members get unlimited access to books, live events, courses curated by job role, and more from O’Reilly and nearly 200 top publishers. Many roles in network administration, cybersecurity, cloud computing, and systems engineering require a strong foundation in Linux. Linux is renowned for its security and stability, which are critical attributes for network environments. This cost efficiency extends to the tools and utilities that run on Linux, many of which are also open-source, providing powerful functionality without additional expenses.
- To avoid future difficulties, you should test using software like Nmap on new Linux distributions and become familiar with networking.
- However, the importance of that distinction is made clear when you look at how people have created projects based on the Linux kernel.
- Many of the packages that come preinstalled with openSUSE can provide you with incredible utility.
- You should plan ahead of time which packages you intend to use to avoid installing useless packages and keep clutter on your Kali system to a minimum.
- This course is for Network Engineers, Network Architects and anyone who wants to learn about Linux from a networking perspective.

Debian is a widely-renowned Linux distribution known for being incredibly stable and high-performance. I hope this blog post provided some useful Linux tricks that will make your life easier. If you have other Linux command line utilities in your toolbox, please feel free to share them in the comment section below.
Linux for Network Engineers: Practical Linux with GNS3
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. Linux and coding are becoming very valuable skills for network engineers that want to expand their horizons in new areas such as SDN, network automation, and DevOps.
Managing Your System with systemd: The Modern Init System for Linux
The monetary investment will be of minimal cost to you since you will only need to spend $60 (at most) to buy a Raspberry Pi (this includes the board, power supply, SD card, enclosure). If you happen to have an old laptop collecting dust, you can install Linux on that and avoid buying any additional hardware. 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. Adding those components to run Linux distros on Android devices is pretty straightforward.
