A common use case is automating tedious tasks in the terminal. Imagine you want to retrieve the serial number of all your devices, it can be very unproductive wasting your time connecting to each and typing show version. With a script, you can have the script connecting to the devices, issue the command and even extract just the serial from it. And, in the end, why not putting everything in an Excel file?

• Use this tool to validate if your SNMP configuration will function with programs like PRTG Network Monitor.
• The software gives full control of the entire configuration across the network, from systems, routers, and firewalls.
• If you’re looking for some command-line capturing, or maybe you want to programmatically trigger packet captures, don’t forget to check out TShark.
• When connecting to a variety of different types of equipment, a telnet, SSH or serial client is required; when this is required both the puTTY and Tera Term programs are able to provide these functionalities.
• WinMTR is used to capture packet drops for a particular path in extended period of time.
• SolarWinds Real-Time NetFlow Analyzer – FREE TOOL A free network traffic analyzer that shows live traffic flows per user, device, address, or protocol.
• I think there’s a ton of overlap there, and in my opinion, very little of it involves learning an actual programming language.

WhatsUp Gold is basically a managing tool highly used by Network administrators and Network Engineers. With this tool, the respective users can look into the status, performance, and functioning of Network Devices and servers in a cloud. PuTTY is available with source code and the user should not have to write new code for every amendment. It was written by Simon Tatham for Microsoft Windows, but later it has been ported to various other operating systems too. It is the most reliable and easy to use software to monitor various network hosts like Router, Switches, and Servers, helping to analyze system conditions like Bandwidth usage or uptime. With the increasing scope of the Networking field, there are lots of advancement brought to make it easier and a lot more accessible to people with the help of Networking tools and software.

A good cable tester detects shorts in a cable and will tell you if the wires inside an RJ-45 connector are arranged correctly. Obviously each of these topics is a rabbit hole – I encourage you to do more research into each, and use this post as a way to get the gears moving. Start thinking about how the tools and methodologies that developers have enjoyed for years can benefit networking. linux network engineer I think there’s a ton of overlap there, and in my opinion, very little of it involves learning an actual programming language. These are very simple applications and the Jinja language is quite powerful; review the documentation and think about how you could use this syntax to drive switch configurations. Using templates helps to enforce consistency and a decided-upon schema.

This type of specialist works with internal and external clients, vendors, and other information technology professionals and is required to communicate in both technical and non-technical language. Working well individually and or in a group may also be required. A networking research and development specialist might need to lift and transport heavy computer equipment, travel, or install networking cables or devices. Network managers are also tasked with developing new systems as an organization changes and grows. Network managers are vital members of an IT group alongside project managers, network engineers, and support staff and must understand the needs of a business from an operational and service-related perspective. Practices like Continuous Integration have really changed the landscape with regard to how code makes it to the light of production.

iperf, Wireshark and TCPTraceroute among useful tools highlighted at Interop conference

The daily activity of a network specialist consists of overseeing groups of PCs that work together, while guaranteeing that users have the right networks based on their business needs. A network specialist ensures that the network works effectively. This may include collecting information on the network’s performance, keeping up on network security and fixing issues as they emerge. A network specialist may need to remove and install software and hardware as well as oversee training new network users and providing security authorizations. Before you step into the computer networking industry, you should know what area you want to specialize in.

It checks for malformed frames, mis-ordered packets and other small things that can go unnoticed in your wireless network. You’re able to write your own rules and dictate exactly what the program is looking for.

I think the bigger point here is that configuration management tools enable us to treat our infrastructure (first servers, now switches/routers/firewalls/etc.) like cattle, instead of pets. This is because they didn’t require anyone to know how to write Python, or Ruby, or even the occasional bash script. Though I’d argue those are insanely useful skill sets, we’re talking about operations enablement here – which applies to both networking and server administration. I think we’ve only begun to see the tools ecosystem take shape in networking; the next 5 years will be very interesting.
