Linux for Network Engineers: How to get started

As results, the router would return an ICMP packet with code “Can’t Fragment Error”, something that I found out with tcpdump. For network engineers, understanding Linux is crucial for managing cloud infrastructure and integrating on-premises networks with cloud services. This community support is invaluable for network engineers, providing assistance and sharing knowledge about best practices, troubleshooting, and new developments. This ubiquity means that network engineers with Linux knowledge can work across a wide range of hardware and software platforms, making their skills highly transferable and valuable. Major network equipment manufacturers, such as Cisco, Juniper, and Arista, often use Linux-based operating systems for their devices.

1. This ubiquity means that network engineers with Linux knowledge can work across a wide range of hardware and software platforms, making their skills highly transferable and valuable.
2. Just want to remind you this is a Cisco technical Forum(we suggest best what we can to guide you in a good direction – we believe).
3. This is something I discovered while listening to the wire with tcpdump.
4. You can create your own firewall using linux or any other operating system..
5. If that is really all you know, I would say go figure out how to download and install Ubuntu or some other version of linux on a computer and start playing with it.
6. Job growth for network engineering and administration in all technologies including Linux is expected to grow 4-5% in the next ten years.

The Importance of Linux for Network Engineers

The traffic control is mainly used to introduce artificial delay, packet loss or jitter to network traffic. It’s really useful and easy to simulate various network conditions when stress testing network connections and algorithm performance. This is one of my most popular posts, and when I wrote it I didn’t think that many others would be looking for that kind of information. It just put down on black and white what I had learned that day. If your video course doesn’t give you what you were expecting, either because of functionality problems or because the content isn’t up to scratch, please mail  with details of the problem. In addition, so that we can best provide the support you need, please include the following information for our support team.

If you have already purchased a print or Kindle version of this book, you can get a DRM-free PDF version at no linux for network engineers cost.Simply click on the link to claim your free PDF. Depends on how much general scripting/programming knowledge you already have and how quickly you learn which is impossible for us to guess. If you looking to learn Python, you need to know Linux too as a basic Operating system, Until you run Python scripting in Windows Box. If you have to learn just one then choose Python as it is more directly relevant at the moment to networking.

With every web service running on a server, it’s now essential to master computer networking. 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.

For example, if you are running a ping test, you will have to use the count option (-c), otherwise it will run continuously in background. Tpcdump is a great utility to troubleshoot network and application issues. For example, at remote sites that are connected with IPSec tunnels back to the main site, many times I was able to figure out why some traffic would make it through the tunnel and some wouldn’t. The cause was that some traffic that used the entire IP payload without accounting for the IPSec header had the DF bit set.

Advanced Packaging Tool (APT)

‘man’ and ‘apropos’ – I was told by my first mentor that these would save my life, and if I couldn’t remember any other commands, these were the two main ones to remember! Apropos allows you to search the command list for something aproximating what you want to do. It’s an incredibly powerful tool, and one I use on a regular basis.

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. Fedora is an open-source distribution that serves as a community equivalent to Red Hat Enterprise Linux (RHEL). RHEL itself is commonly chosen as the operating system for enterprise-level systems. Disable path length limit and set environment variable for Python.

Train to work with server and database administrators to identify network capacity requirements and recommend hardware and services to support network usage. It’s also one of the most popular posts we have on our blog. The list will keep expanding, but for now let’s discuss how you can get your hands on a Linux box with as little cost as possible. 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 that all of those offerings have an expiration date, so you won’t be able to use them in the long term.

I would also recommend trying to run your Linux in a virtual machine to start. If you have control of your own machine (not a corporate computer) and you can spare a little memory, processor cycles, and hard drive space. Go get Sun VirtualBox (FREE!) and you can run as many different Linux distros, FreeBSD, OpenBSD, etc. as your system will handle. If you royally screw one up while you’re learning then just blow it away and start again. Since it’s a virtual machine you can also save it in a certain state BEFORE you make critical changes so that you can just revert back to that state without blowing it away.

Having access to the actual hardware gives you the opportunity to “mess around” with more aspects of the system. You can create your own firewall using linux or any other operating system.. If that is really all you know, I would say go figure out how to download and install Ubuntu or some other version of linux on a computer and start playing with it.

When I started blogging about Linux and network engineering I was coming from a strong background in Linux administration, and I was building my networking knowledge. At the same time, some of the largest networking vendors and several newcomers had already started offering integration of networking management with Linux environments. This prompted me to start putting down on the NetBeez blog, what I already knew around networking related to Linux, but also what I was learning in the space for a broader audience. 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. 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. 1) A lot of network operating systems are based on Linux, or have a Linux shell you can access, or use Linux type commands.

We help you gain critical insights and make more informed decisions across your business priorities. But I would focus on learning the Network Engineering stuff first and circle back around when you have that solidly under your belt. Just as you should know something about how windows servers work. However with just starting out get a CCNA and get some job experience.

Security and Stability

Of course, I use that for machines on the same LAN that are protected and I don’t care much about security or encryption. On our side, we’ll do our best to give a smooth but solid introduction to Linux for network engineers. 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.

I’m interested in learning network administration (ip addressing, SNMP, building Linux firewalls ~ I’m currently learning and refining skills using freeradius through Ubuntu). How practical is doing all of this on Linux used in the workplace? I read online they suggest learn Python from several forums, however to me it seems the tasks mentioned above make Linux a valuable skill to have as a network engineer.
