Wireshark is a protocol analyzer and one of the go-to networking tools for organizations of all sizes when network issues need to be troubleshot with a high level of granularity.

The benefit of using Wireshark to analyze network traffic is that you will be able to view the raw network packets, and this will often allow you to identify the root cause of an issue. This can be especially helpful in situations where it is unclear which application is not doing what it is supposed to or when you try to reverse engineer the functionality of a poorly-documented program.

The tradeoff here is that you will have a lot of data to parse through, so some technical knowledge may be required to drill down and identify the important information. On Windows operating systems, link-layer packet captures with WireShark are often made possible using Winpcap either Winpcap or Npcap is required. For a deeper dive on Winpcap, Windump, and tcpdump, check out our recent article on packet sniffers and network analyzers and download the tcpdump cheat sheet.

Wireshark is an excellent tool for processing packet data. There are a number of other tools that work well with Wireshark to create an even better data analysis system. The data search system Elasticsearch is free to use and it comes with complementary modules for logfile management and data display.

Together this suite is called the Elastic Stack. The illustration below shows how the Elastic Stack can be used with Wireshark to create an improved data analysis system from components that cost nothing. Although this setup looks complicated, all of the tools shown in this diagram are designed to work together and the Elasticsearch website includes guides on how to put this system together. Nmap is a popular security auditing and network exploration tool released under a custom open source license based on GPLv2.

While the most popular use cases for nmap are security scans and penetration testing, it can prove quite helpful as a network troubleshooting tool as well. For example, if you are dealing with an unfamiliar app and want to find out what services are running and which ports are open, nmap can help. Zenmap is the official nmap GUI and is a good way for beginners to start working with nmap.
