Wireshark is a powerful tool that requires sound knowledge of networking basics. Administrators use it to identify faulty network appliances that are dropping packets, latency issues caused by machines routing traffic halfway around the world, and data exfiltration or even hacking attempts against your organization. It lets you put your network traffic under a microscope, and provides tools to filter and drill down into that traffic, zooming in on the root cause of the problem. This free software lets you analyze network traffic in real time, and is often the best tool for troubleshooting issues on your network.Ĭommon problems that Wireshark can help troubleshoot include dropped packets, latency issues, and malicious activity on your network.
