In the Wireshark menu, go to Capture Options. When running Wireshark, the first step is always to start a capture on a designated interface. Simply hit next and choose all the defaults in the Wizard to install. Capture filters (like tcp port 80 ) are not to be confused with display. 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. In this example we will be using Wireshark-win64-2.6.6.exe. The master list of display filter protocol fields can be found in the display. 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.
