At first glance, the networking configuration of a single Linux host may seem trivial. However, there are actually many robust network features inside of Linux system. Many of the top open source projects find ways to leverage these features in interesting, and sometimes complex, ways. Having an understanding of the inherent networking features in Linux is a must if you want to understand how they can be used together.
Real-life Projects in Virtual Lab
Wireshark offers tantalizing information about packets moving across a network, Nmap provides useful clues about network security, and SmokePing provides interesting visualizations of network latency. The Senzing tool is somewhat peripheral to networking and security, but is useful enough in certain situations. Senzing is able to find similarities and relationships within disparate databases. Senzing is deployed as an API for most major platforms, and is free to download and use to analyze up to 100,000 records.
- As a distribution designed for penetration testing, Kali Linux comes with a massive variety of preinstalled tools that network engineers are certain to find useful.
- She currently attends Eastern New Mexico University as a computer science major.
- In addition to the Network responsibilities, this role will also specifically contribute to the Tech Operations team.
- Infection Monkey is a continuous penetration testing tool designed for any size network.
- 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.
- Tools and applications that were once reserved for the server world become available.

Out of the box, you won’t have any issues configuring basic network settings through YaST (Yet another Setup Tool). Many of the packages that come preinstalled with openSUSE can provide you with incredible utility. Linux is commonly preferred among network engineers—so if you’ve thought about installing it for your work, you’re not alone. I have been told by many that to become a entry-level network engineer usually takes an ‘in’ with someone you know.
He is the CEO of the Tech Writers Bureau, a group that creates technological thought leadership content for organizations of all sizes. The fprobe tool is generally used to sit at a specific point on a network and record data about traffic moving through that point. It can be used to help locate functions that are eating up too much bandwidth or even shadow IT that is generating traffic or performing functions that are not supposed to be allowed on the network. In addition to the Network responsibilities, this role will also specifically contribute to the Tech Operations team. The Tech Operations team is responsible for safe operations, intelligent planning, and thoughtful execution of our AET platform. The people who thrive here share our belief that it’s not just what we do that matters–it’s how we do it.

For instance, Docker is able to deliver container network isolation by leveraging network namespaces 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. Despite modifications, having access to the native Linux shell affords us some significant wins. Tools and applications that were once reserved for the server world become available.

This course will help network engineers familiarize themselves with the DevOps tools needed to assist in the DevOps/Agile process. In addition to the native Linux features, there are other projects such as Open vSwitch (OVS)that seek to extend Linux networking functionality. While OVS isn’t native to Linux, it does have its own Linux kernel module https://investmentsanalysis.info/united-training-chosen-as-authorized-comptia/ and is used extensively with open source projects such as OpenStack. 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.
