Top 5 Linux Utilities for Network Engineers

The Linux Engineer is responsible for the hardware and software components of the network and other devices within the business setting for current and future environments. This includes planning, developing, installing, configuring, maintaining, supporting, upgrading, and optimizing all network hardware, software, and communication links. This role requires the individual to proactively monitor system performance and issues and respond to incidents that require attention in a timely manner. There’s been a lot of talk recently about what network engineers should learn to stay relevant.

While the freelance market isn’t ideal for every position, Linux engineers are often a great fit. Learn the most in-demand business, tech and creative skills from industry experts. According to Lightcast, the median advertised salary for a Linux engineer is $99,000 as of July 2022. Although, there are many factors that influence salary such as location, job level, years of experience, company size and more. It’s common for a Linux engineer to hold a bachelor’s or master’s degree in computer science, computer engineering or engineering or have equivalent experience. The best approach would be to use either an old laptop and install Debian based Linux on it or to buy a single board computer such as the Raspberry Pi.

According to Gartner, Android’s share in the smartphone market for the first quarter of 2016 was 84%. Furthermore, Linux also has a future in appliances, such as drones and smart TVs. Since it is possible to customize Linux for as per the particular needs of each user, web developers also began embracing it as far back in the 1990s.

  • Having the ability to access the native Linux operating system gives us great flexibility and opens the door to many new possibilities.
  • Having an understanding of the inherent networking features in Linux is a must if you want to understand how they can be used together.
  • There’s been a lot of talk recently about what network engineers should learn to stay relevant.
  • It’s also a good example of the direction things are heading and the skillset that will be required to effectively work and troubleshoot Linux host networking.
  • Imagine you have just been hired by Simco Financial Services, Inc., to join their Network Engineering team.
  • Share what you’ve learned, and be a standout professional in your desired industry with a certificate showcasing your knowledge gained from the course.

If you want to be the MacGyver of your network, you must know the basics of netcat. If you use it in client mode, it’s similar to telnet, and you can create a TCP connection to a specific port and send anything that you type. Another use case is testing whether your firewall is blocking https://remotemode.net/ 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.

  • Train to work with server and database administrators to identify network capacity requirements and recommend hardware and services to support network usage.
  • Of all the Linux distributions, one of the most highly regarded among network engineers is Fedora—and there’s a simple reason why.

Engineers need to understand how the hardware of Linux OS works and must be knowledgeable about Storage Area Networks (SAN) servers. They set up configurations for network, database, and high availability services, besides designing and developing OS system configurations for software packages. A Linux Engineer installs and monitors Unix/Linux open-source operating systems and caters to the client’s needs in this environment.

The 6 Best Linux Distros for Network Engineers

So as you can see, there are a variety of reasons to learn more about Linux as a whole. But as with any new skill, the hardest part of learning is finding where to start. If you’re new to Linux as a whole, focus on getting comfortable with the command line. Learn how to get around, inspect system parameters, and make configuration changes. Once you get comfortable with the basics, start focusing on individual pieces of technology.

  • When you have a specific, well-defined goal in mind, this can be a great path to hiring an experienced Linux engineer.
  • The cause was that some traffic that used the entire IP payload without accounting for the IPSec header had the DF bit set.
  • For example, execute netcat in server mode on a host behind your firewall and then execute netcat in client mode from outside the firewall.
  • Upwork is a freelance talent network that helps individuals connect with experts in a variety of fields to accomplish project-based needs.
  • For the routing process, we first used Zebra and then Quagga (which at the time supported OSPF).
  • 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.

Strong communication skills are required candidate typically works with customers for support and new initiatives. For instance, Docker is able to deliver container network isolation by leveraging network namespaces linux network engineer along with basic Linux interfaces and bridging. Network engineers looking to understand these open source projects should make sure they understand the Linux networking primitives that these tools leverage.

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. 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.

OVS is a prime example of how a Linux host can be extended to provide more than basic level of network attachment. It’s also a good example of the direction things are heading and the skillset that will be required to effectively work and troubleshoot Linux host networking. Using the CLI for a given vendor meant learning that vendor’s unique syntax.
