The Tools and Scripts a Network Engineer Can't Live Without

A network engineer without the right tools is like a chef without a knife. Sure, you might get the job done, but it's going to be messy, frustrating and take twice as long. In this field, efficiency is everything, and troubleshooting feels like solving a mystery. You don't just want the basics; you want the game-changer tools that turn chaos into order.

Over the years, I've developed a personal arsenal of tools that have saved my sanity more times than I can count. These aren't just recommendations from some checklist. They're battle-tested companions that have helped me through network meltdowns and impossible deadlines.

Command Line, Configuration Management and Wireshark

First off, the humble command line remains my home base. Whether you're connecting to devices via SSH using tools PuTTY , MobaXterm or Termius, the command-line interface helps network engineers get the real work done. Sure, slick GUIs are out there, but when the clock is ticking and a switch stack is misbehaving, nothing beats the speed and control of raw CLI.

Most engineers I know keep a personal stash of known, good configurations in a text folder somewhere. It might not be the cleanest system, but when something breaks, having a tested template on hand is worth gold.

Then there's Wireshark . Ask any seasoned engineer about it, and you'll see their face light up like they're talking about an old friend. It's the go-to tool for digging deep into what's happening on the network.

Monitoring and Alerting

When highlighting important network engineering tools, we can't leave out monitoring and the role monitoring tools play in a network landscape. Monitoring is non-negotiable. Whether you use SolarWinds, PRTG, Zabbix or another provider, it's crucial to have eyes on your environment.

More than that, however, good alerting is key. The goal isn't to know everything; it's to know the right things at the right time. A well-tuned alert system tells you when something is wrong before your users or boss do.

Text Editors

On the more day-to-day side, a good text editor goes a long way in helping you resolve a crisis in one shot. Notepad++ is an unsung hero for staging configs, writing quick scripts or comparing outputs. Visual Studio Code (VS Code) is another solid choice , especially if you're working with Markdown docs, Git or APIs. These aren't glamorous tools, but they're the digital equivalent of a favorite wrench: comfortable, reliable and always within reach.

Process Management

In networking, processes matter too. Ticketing systems, such as Jira and ServiceNow, might seem like overhead, but they provide structure and can be vital for larger teams that need to track changes and prevent "surprise" outages. While proper documentation might not feel urgent today, when something fails in six months and you're trying to remember what has changed and why, that Wiki entry or Markdown note you wrote might be the only breadcrumb you have.

Ping and Traceroute

Of course, we can't forget the classics. Ping and traceroute are the network engineer's equivalent of a stethoscope. These are the first tools most network pros learn when starting out, yet they never stop being useful.

You can have all the fancy dashboards and AI-powered analytics in the world, but when someone calls in and says, "The internet's down," what's the first thing you do? You open a terminal and type ping. Why? Because it's fast, simple and often gives you an immediate pulse check.

LAN Tester

Every network engineer's kit has that one underrated but essential gem: the LAN tester. It's not flashy, but when things go sideways, it clearly tells you if the cable is good or not -- no guesswork or debates. It's quietly saved more situations -- and reputations -- than most people realize.

The Engineer's Mindset

At the end of the day, the best tools are the ones that make your work easier, quicker and more reliable. It's not about having the flashiest interface or the newest software. It's about having tools you can count on.

Even more important is having a mindset that's always open to learning , always looking for ways to improve and never settling for doing things the hard way when there's a better option out there.
