Knowing which TCP/IP ports of a host are listening for incoming connections is crucial, especially when you’re hardening a server or locking down network equipment. Nmap allows you to quickly verify that; just run the Nmap command followed by the hostname or fully qualified domain name. I do have a background in Unix/Linux and currently work as a Cisco network engineer.
Embracing Linux and building expertise in this area is a strategic move for anyone looking to succeed in the field of network engineering. Many roles in network administration, cybersecurity, cloud computing, and systems engineering require a strong foundation in Linux. Knowledge of Linux is therefore essential for network engineers working in environments that adopt DevOps practices.
As a result, network engineers who use Fedora enjoy a greater level of linux for network engineers familiarity with the RHEL systems they may encounter throughout their careers. Of all the Linux distributions, one of the most highly regarded among network engineers is Fedora—and there’s a simple reason why. Linux is commonly preferred among network engineers—so if you’ve thought about installing it for your work, you’re not alone. Job growth for network engineering and administration in all technologies including Linux is expected to grow 4-5% in the next ten years. There are many ways to transfer a file between two hosts, and when you are looking for a quick and dirty way TFTP is one of the easiest ways to do it.

Specifically, I noticed that applications using the entire IP payload and also enabling the DF (don’t fragment) setting, would fail. Both of these have their merits (I’m a vi person myself), and both have strong followings. If you can get one of those straight, you can do pretty much anything. Though there is pico/nano and joe, depending on which linux distribution you use.
You can view all topics covered in this course below on this page under ‘Lessons’. Perhaps if you could be more specific about the area you are interested i could suggest some good books/study material. Get Mark Richards’s Software Architecture Patterns ebook to better understand how to design components—and how they should interact. Take O’Reilly with you and learn anywhere, anytime on your phone and tablet. There are also live events, courses curated by job role, and more.
- Linux is commonly preferred among network engineers—so if you’ve thought about installing it for your work, you’re not alone.
- 1) A lot of network operating systems are based on Linux, or have a Linux shell you can access, or use Linux type commands.
- I’ve used iperf many times to troubleshoot bandwidth issues, verify whether the ISP would honor the DSCP marking, and estimate the jitter value of VoIP traffic.
- My Linux work and network engineering work live in two different silos.
- Its significance in this field cannot be overstated, as it offers a robust, versatile, and secure environment for managing and optimizing network infrastructure.

That said, I do think knowing command line interface anything trains your brain in good ways to be a better IT engineer of any sort. There are people who get by using wizards, but they will only get so far. The people who get under the hood and use command lines and scripting are the real professionals. We also provide a PDF file that has color images of the screenshots/diagrams used in this book. Come back to expert answers, step-by-step guides, recent topics, and more. Python is not a difficult language to start with especially if you are only using objects etc. rather than designing your own classes etc. and you can become relatively productive quickly.
SSH Server
Network engineers can modify the operating system to fit specific network requirements, create custom scripts, and automate network management tasks. Use iperf to assess the bandwidth available between two computers. You can choose between TCP or UDP traffic and set the destination port, bandwidth rate (if UDP is selected), DSCP marking, and TCP window size. The UDP iperf test can also be used to generate multicast traffic and test your PIM infrastructure. This will help you manage your network devices via ssh remotely. While some Linux distributions are better suited to network engineers, almost any Linux distribution can be used with the right software and configurations.
- But you are not going to be as good as the guy sitting next to you that does know them.
- Network engineers will often run into Linux-based network operating systems and command lines.
- As noted by Brandon, the first thing you should do is download Ubuntu and get it up and running on your PC.

You can actually purchase laptops with it preloaded if you want. Proficiency in Linux opens up numerous career opportunities for network engineers. From routers and switches to firewalls and servers, many network devices and systems run on Linux or a variant of it. 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. Linux, an open-source operating system, has become a cornerstone in the world of network engineering. 2) Network Automation tools such as Ansible don’t run the command node on Windows.
I think Python is really important and can make huge difference for networking but dont forget about networking. There are a lot o technology coming besides sdwam like sda and aci. If you master this technokogy, Python can or not be important. If you need to choose, no doubt Python is better and way more importante for networking. Rather focus on learning and becoming good t using 1, however its really only worth it if I can apply it in the workplace. The dark web sounds fun, but there are some important security steps you need to take first.
If not it seems a bit depressing to know I have to spend hundreds of hours at least in next few months to learn Python/Linux after Ive been studying 10 hours a day on Cisco over last 4 months. With different flavors called “distributions or distros,” there are currently more than 2 hundred in the industry! Learning how to work with different distros is a key skill for network engineers and developers. This eBook reflects part of my journey picking up knowledge around networking management, testing, and monitoring with Linux by including a broad gamut of topics. All modern operating systems ship with ZIP file extraction built in.
I came across this problem when developing the NetBeez WiFi agent. I had to deal with sending test traffic (ping, dns, HTTP, traceroute, etc) through the wireless interface, but use the wired interface as the control interface for the agent-dashboard communication. In that scenario directing traffic to a specific interface had to do with setting proper routing priorities. In this series of posts we will try to make a smooth introduction to Linux for network engineers that have zero to very little knowledge of 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.
