Troubleshooting Tools In A Network Engineers Arsenal !!

As a network engineer you come across some corner situations where you need to play previously captured packet or construct a packet and play to DUT to see the behavior. Quite helpful to trigger bugs etc, lately in 3-4 years I have seen the colasoft popularity growing and there is a good amount of literature available on net which teaches you to use this tool. If the installer ask you to create an user account – create it. Aim to learn customised advanced installation later on once you have some confidence on Linux; Google it for details.

Honestly they don’t, no matter how many random Internet strangers tell you so on Reddit. There’s absolutely no reason you’ll need to know anything other than CLI for Cisco, Juniper, and maybe Arista. And tons of companies use Hyper-V in the enterprise setting, entire data centers without even a bit of Linux. You should learn Linux because you’re only setting yourself up for a world of hurt later in your career if you plan on only sticking with one OS.

The most useful software without a doubt is Putty which is available for windows as well as mac machines. SuperPutty is an extension of Putty software and provides tabbed window just like you will have in SecureCRT which is paid terminal software. 1) A lot of network operating systems are based on Linux, or have a Linux shell you can access, or use Linux type commands. I’ll show you an example using Cisco, Arista and Cumulus Linux. Pretty much everything is running some flavor of unix, running common unix tools in containers, or or just using linux to manage the hardware. Almost all Cisco hardware is running some flavor of linux, and knowing the backend has same me multiple times when shit goes sideways.

Historically, most network engineers have been focused on the CLI. The reasoning for this was simple, it was our only option. Using the CLI for a given vendor meant learning that vendor’s unique syntax. This meant that being able to configure a Cisco switch didn’t imply I could configure a Juniper switch. If we consider that most network switches are built off of a Linux base, and provide similar functionality, the CLI becomes an abstraction of the underlying Linux system.

Top Tools To Make A Network Engineers Life Easy

You can setup iPerf in two systems connected on two ports of the router and test the throughput of the router. The wireshark although great but it needs to be installed, what about a tool which is integrated with linux/Mac OS and can provide similar functions. For windows users you can install windump which is related with tcp dump but windows version to provide same capability on Microsoft windows based systems. With most network operating systems based on Linux and the number of Linux-based projects like OpenStack growing, Linux skills are a requirement for networking pros. The best Linux distribution for pen testing is Kali Linux, hands down. Kali is a Linux distribution that includes a lightweight desktop environment and tons of popular networking, programming, and tools. It is the de-facto Linux distribution for cybersecurity analysts and researchers.

  • All major networking vendors use Linux as is the underlying operating system on their routing, switching, and security devices.
  • For MAC users native terminal is a great tool however it gets annoying sometime when great protocols like telnet is not available in MAC Terminal.
  • Different Linux distributions (Redhat/Debian/Ubuntu/CentOS/…) use different tools for package management.

We’re having a discussion about whether to use the service tag or the serial number for inventory and insurance purposes for the Dell devices. This is obviously not a problem for non-Dell devices that only use a serial number, but since Dell uses both, I’… But I would focus on learning the Network Engineering stuff first and circle back around when you have that solidly under your belt. You just need to know networking, really really well. Monitor and control system processes using top, renice, kill etc. Conduct system performance tunning and capacity planning.

But, because Elementary OS is based on Ubuntu, that means you can use Aptitude to install any packages from the Ubuntu and Debian repositories. The developers behind Elementary OS developed their own desktop interface called Pantheon. Pantheon is one of the few non-traditional desktop environments available for Linux. Pop OS is based on Ubuntu, so its applications and application repositories are version-locked. Because Pop OS is based on Ubuntu, it has access to the entire Ubuntu repository.

So, instead, we are going a different route and recommending Manjaroas the best Linux distribution for rolling updates. The world of Linux distributions follows two philosophies regarding software and updates. First, some OSes, like Ubuntu or Debian, will version lock applications. That way, major releases of applications aren’t deployed by accident that might break something. On the other hand, other Linux distributions, like Arch, have rolling updates. In this case, updates for applications, whether they are major and minor releases, are available.

More From 25 Days Of Linux

While the field is rapidly changing, I’m going to suggest that one of the most important areas we as network engineers can focus on is Linux. First off, it’s becoming more and more apparent that most network operating systems are based on some variation of Linux.

Man lets you check the manual for a specific command. It’s an incredibly powerful tool, and one I use on a regular basis.

2) Network Automation tools such as Ansible don’t run the command node on Windows. In addition to the native Linux features, there are other projects such as Open vSwitch that seek to extend Linux networking functionality. While OVS isn’t native linux network engineer to Linux, it does have its own Linux kernel module 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.

Very useful in case you are troubleshooting performance issues in a certain path. For MAC users native terminal is a great tool however it gets annoying sometime when great protocols like telnet is not available in MAC Terminal. Hence you need something which you can use for Telnet etc whenever needed. FileZilla is another cool open source which I have been using for very long time. This tool is used for file transfer over FTP,SFTP and can work in Client and Server mode. Very easy to use and you can rely on it for any size of transfer.

Watch:  Runs A Command Every 2 Seconds

Those other Linux distros also have less potential for issues since they aren’t rolling OSes. Nonetheless, suppose you want a Linux distro with the latest and greatest software. In that case, Manjaro might be the best Linux distro for you. It’s easier to use than other distributions like Ubuntu. Once Manjaro is installed, you will be greeted with vanilla copies of Gnome, KDE, or whichever desktop operating system you want to use. We should mention that Elementary OS is based on Ubuntu. Because of that, the updates for Elementary OS can take six months or more to roll out after Canonical releases major versions of Ubuntu.
