ENThe 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. Having a solid linux network engineer understanding of Linux as it relates to both basic operations and networking is a skill worth having. Another area of Linux we should focus on is the Linux networking stack. At first glance, the networking configuration of a single Linux host may seem trivial.
Only experienced network engineers or developers can modify and access the shadow file. 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.
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.
Network engineer salaries and job prospects
Network Automation tools such as Ansible don’t run the command node on Windows. You are probably going to use Linux with tools such as Ansible, Netmkio, NAPALM and other network automation tools. SDN controllers such as OpenDaylight, ONOS, RYU and APIC-EM run on Linux.
He has also personally developed Cisco engineer utilities such as the VPN Config Generator, software, training materials, EBooks, videos and other products which are used throughout the world. 6) A new breed of network devices from companies like Facebook, Microsoft and Cumulus Linux use Linux. Learn the most in-demand business, tech and creative skills from industry experts.

Share what you’ve learned, and be a standout professional in your desired industry with a certificate showcasing your knowledge gained from the course. 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. Imagine you have just been hired by Simco Financial Services, Inc., to join their Network Engineering team. In this initial project, you will demonstrate your ability to analyze network traffic, configure a basic network, and make an RDP/VNC connection on…

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. In the future, CentOS Stream is likely to become the best option for anyone seeking an RHEL-adjacent distribution. Many of the qualities of RHEL that make it attractive as an enterprise solution are just as appealing for independent users. As one of the most popular enterprise distributions, RHEL is a great option because it is robust and reinforced.
Each version of RHEL has a 10-year lifecycle, meaning that you’ll be able to use your chosen version of RHEL (and enjoy little to no compatibility issues) for years.
- For instance, Docker is able to deliver container network isolation by leveraging network namespaces along with basic Linux interfaces and bridging.
- One of the biggest advantages of using Debian for network engineering is that it has an incredible package-rich repository with over 59,000 different software packages.
- Virtual Lab allows you to get practical experience under the supervision of people that not only know what they’re doing but are leading the way in their respective industries.
- Statistics reveal that 76% of organizations globally use a multi-cloud operating model, at least one shared and one private cloud.
Certifications like CompTIA Linux+ validates the skills of IT pros with hands-on experience configuring, monitoring and supporting servers running on the Linux operating system. Check out the CompTIA Career Roadmap to see what other certifications can help you become a Linux engineer. 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).
- In the future, CentOS Stream is likely to become the best option for anyone seeking an RHEL-adjacent distribution.
- Enter into your new industry with confidence after using our resumé services and interview assistance.
- Some other career options include network manager, cloud networking architect, network design expert, network analyst, and network technician.
- The cause was that some traffic that used the entire IP payload without accounting for the IPSec header had the DF bit set.
Recommend hardware appropriate for the network and support that hardware as needed. Learn how to manage and monitor Linux network usage and optimize it. Implement security systems and ensure the security of the data stored on your network. On our side, we’ll do our best to give a smooth but solid introduction to Linux for network engineers.
Get ready with one of these options and in the next post we’ll talk how to access your Linux box remotely and without a password (but securely) with ssh. Enterprise Networking Design, Support, and Discussion.Enterprise Networking –Routers, switches, wireless, and firewalls. You should test out software like Nmap and familiarize yourself with networking on your new Linux distro so that lack of familiarity doesn’t become an obstacle later on. Much like Fedora, CentOS Stream is a distribution that stays in line with the development of RHEL.
