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. The brilliant part of Linux is that there’s a multitude of “how to” articles on the internet that can walk you through just about anything you’re looking to do. The key here is to get hands-on experience that you can continue to build on. Job growth for network engineering and administration in all technologies including Linux is expected to grow 4-5% in the next ten years.
- Becoming a Linux engineer means overseeing the processes of installing servers and transitioning hardware from other operating systems into Linux.
- Having access to the actual hardware gives you the opportunity to “mess around” with more aspects of the system.
- First off, it’s becoming more and more apparent that most network operating systems are based on some variation of Linux.
- Virtual Lab provides hands-on, real-world practice using your newly gained skills on projects defined by industry experts, adding practical experience to your resume.
- For the routing process, we first used Zebra and then Quagga (which at the time supported OSPF).
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. 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.

Check out the CompTIA Career Roadmap to see what other certifications can help you become a Linux engineer. The world of Linux is growing, and there’s demand for up-and-coming engineers. Linux can be a complex system to learn, but it’s a valuable skill for IT professionals. Becoming a Linux engineer means overseeing the processes of installing servers and transitioning hardware from other operating systems into Linux. If you want to perform testing and troubleshooting while monitoring system performance, then Linux engineer could be your next move. Modern courses and learning activities in state-of-the-art technologies prepare you for your new career.
If you use it in client mode, it’s similar to telnet; you can create a TCP connection to a specific port and send anything that you type. When I worked full-time as a network engineer, my Linux skills helped me with the tasks of design, implementation, and support of enterprise networks. Here is a list of some of the command-line utilities I recommend to network engineers. It can give you useful information about https://remotemode.net/ what’s running on network hosts. With Nmap you can, for example, scan and identify open and filtered TCP/IP ports, check what operating system is running on a remote host, and do a ping sweeps on an IP subnet or range. With Nmap you can, for example, scan and identify open and filtered TCP/IP ports, check what operating system is running on a remote host, and perform a ping sweep on an IP subnet or range.

As results, the router would return an ICMP packet with code “Can’t Fragment Error”, something that I found out with tcpdump. 1) A lot of network operating systems are based on Linux, or have a Linux shell you can access, or use Linux type commands. Im starting to look for network engineering jobs and alot of them are asking for linux experience. 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.
- There are a few free options if you are comfortable with working on the cloud.
- With Nmap you can, for example, scan and identify open and filtered TCP/IP ports, check what operating system is running on a remote host, and do a ping sweeps on an IP subnet or range.
- If you can read on the server whatever you type on the client, then the firewall is not filtering the connection.

- With Nmap you can, for example, scan and identify open and filtered TCP/IP ports, check what operating system is running on a remote host, and perform a ping sweep on an IP subnet or range.
- For example, at remote sites connected with IPsec tunnels back to the main site, I was often able to figure out why some applications would make it through the tunnel and some wouldn’t.
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. You can also use it to open a TCP/IP port and read from standard input. 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.
Skills you’ll gain
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 linux network engineer that all of those offerings have an expiration date, so you won’t be able to use them in the long term. I have seen quite a few linux certification programs but am wondering what is valued what isnt.
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. 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).
