When these problems occur, the solution is to use the external tooling described in this article to diagnose networking issues. However, the client libraries make network calls over various protocols, which may lead to troubleshooting scenarios that extend outside of the troubleshooting scope provided. These issues include scenarios that range from troubleshooting an unexpected response value from a service, to root-causing a connection-closed exception.įor client-side troubleshooting, the Azure client libraries for Java offer a consistent and robust logging story, as described in Configure logging in the Azure SDK for Java. To check if promiscuous mode is enabled, click Capture > Options and verify the “Enable promiscuous mode on all interfaces” checkbox is activated at the bottom of this window.This article describes a few tools that can diagnose networking issues of various complexities. If you have promiscuous mode enabled-it’s enabled by default-you’ll also see all the other packets on the network instead of only packets addressed to your network adapter. Wireshark captures each packet sent to or from your system. You can configure advanced features by clicking Capture > Options, but this isn’t necessary for now.Īs soon as you click the interface’s name, you’ll see the packets start to appear in real time. For example, if you want to capture traffic on your wireless network, click your wireless interface.

Capturing PacketsĪfter downloading and installing Wireshark, you can launch it and double-click the name of a network interface under Capture to start capturing packets on that interface. Don’t use this tool at work unless you have permission. Just a quick warning: Many organizations don’t allow Wireshark and similar tools on their networks.
