The Infection Monkey program is available as a free download and the source code can be found on GitHub. Thankfully, there are many great tools available to help network engineers complete their never-ending tasks. Current trends are pushing the skillset of the network engineer and the server administrator closer together. 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. On the Linux server side, the days of simple host networking are quickly evaporating as more of the network logic moves down into the Linux host.

As well as automating and streamlining system administration tasks, Linux engineers may also train and support other IT personnel. Since they will be working with both client and technical teams, Linux engineers should have strong communication skills and be flexible in their work schedules. ETS also includes network troubleshooting tools that help engineers identify and resolve network issues quickly. These tools provide real-time network diagnostics and troubleshooting capabilities, enabling engineers to quickly pinpoint the root cause of network issues and take corrective action. Network engineers ensure all network systems are functioning properly and their fundamental goal is to provide maximum network infrastructure, security, and performance to the end users.

A telecom project manager is responsible for handling a team, which includes engineers and client representatives. The main role of a project manager is to analyze, maintain, and control all the aspects of the project, from both a technical and managerial perspective. The desired skills of a project manager include understanding logical configuration, having good client-interfacing skills, and a clear understanding of telecom business scenarios. A VOIP Engineer plans, designs, and implements the voice infrastructure and proposes solutions to the existing voice and data networks.

Network Engineer

Your expertise will contribute to ensuring the stability, security, and optimal performance of our Linux environment. Nmap, short for Network Mapping, is a free and open source tool used for vulnerability checking, port scanning and network mapping. It’s a powerful tool that is often able to discover hidden vulnerabilities in networks that are missed by other programs. There is a large community that supports Nmap today, including the original developer, Gordon Lyon. The tool, which anyone can get for free, is downloaded several thousand times every week according to the community that maintains it. And the network itself if being extended to the cloud, the edge and to the home office.

  • A network analyst is required to design, plan, analyze, and provide technical help for data communication networks or groups of networks in the organization.
  • It is open-source software that allows network engineers to access remote systems over a network connection.
  • SolarWinds Engineer’s Toolset (ETS) is a commercial Network engineering tool that is designed to help network engineers troubleshoot and analyze complex networks.
  • It helps network engineers to identify and resolve problems before they get out of hand.
  • Many network analysts discover that they become key personnel in both the business and technical sides of an organization where an important role is identifying business issues and applying a technical solution.

The Wireshark analysis tool is a free and open-source program primarily used to capture and analyze packets of data moving through a network. Wireshark was created back in 1998 by Gerald Combs, but don’t let the age of Wireshark fool you, because it’s just as useful today as when it was created. Wireshark enables network engineers to put network interface controllers (NICs) into promiscuous mode to observe most traffic, even Unicast traffic which is not sent to a controller’s MAC address. All versions of Wireshark and the source code are fully open source and can be downloaded for free. This course is designed specifically to introduce both new and experienced professional network engineers to the Linux operating system and environment.

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. While I think this is a fair generalization, it’s also fair to say that most vendors don’t run a completely vanilla version of Linux or the Linux kernel. NetBrain’s collaboration and knowledge-sharing capabilities are also noteworthy. It provides a central platform for engineers to collaborate on network issues, share knowledge and expertise, and document network changes and configurations.

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. Attacks are on the rise across the board, and attackers are constantly looking for vulnerabilities or backdoors, upping the need for solid and secure networking to act as an early warning system for cybersecurity defenses.

  • Another important feature of PingPlotter is its ability to provide a visual representation of network performance.
  • It provides a central platform for engineers to collaborate on network issues, share knowledge and expertise, and document network changes and configurations.
  • This analysis can help engineers to identify potential issues before they become critical and proactively implement solutions to prevent them from occurring.
  • It can also be used to identify devices that are connected to a network without authorization or that may be vulnerable to attacks.

First, Cacti provides a fully distributed and fault tolerant data collection framework. Cacti can be used both as a network monitoring tool or as a companion to other tools by providing a graphical interface for their data. There’s been a lot of talk recently about what network engineers should learn to stay relevant.
