Now that collecting network packets is enabled, one should try to repeat the failing activity, or contact the license server again (to stick to our example here), by running the part of the Squish setup again where the license issues occurs, and check to see if packets show up in the list.Īfter this, the collected network packets can be saved via Ctrl+s or the File menu in File > Save. As you can see after selecting the device, some packets start to appear on the screen. Let us select the interface ‘eth01’ in our case. Select a device to start capturing packets by double-clicking its name. When packets have been collected, new lines will be added to the list. Capturing Packets with Wireshark After launching the Wireshark, you will see a list of devices to capture packets from. When starting collecting network packet, the UI will change to look somewhat like this:
To stop collecting network packets, click on the red square next to the shark fin, or press Ctrl+e again. To start collecting network packets, click on the blue shark fin on the toolbar or press Ctrl+e. In this, "PORT_NUMBER" must be replaced with the desired numeric port number, for example in case of the license server it may be "49345" (the default of the license server, but the specific license server setup may use a different TCP port). The ideal filter for this: tcp port PORT_NUMBER To capture only the packets from the license server, one needs to setup a filter in this field: If in doubt, please select all interfaces available for capturing. If no actual network hardware interfaces are shown here, one may need to grant ones these rights, or contact the system administrator. If the current user account has no network monitoring rights, one will only see a few virtual interfaces here. Normally that is either the Ethernet or the WiFi interface, depending on how the computer is connected to the network. Here one must select the network interface that the packet for the license server will go through. Here all the network devices that the current computer has can be seen. When first launching Wireshark, it will looks somewhat like this:
One can refuse this, but then one needs to start the application as an administrator/with elevated rights for it to be able to capture network packets. If the installer asks if one wants to grant access to regular users for capturing of packages. , and for Linux it can usually be installed via the package manager of the Linux distribution.

In this article we will demonstrate how to use Wireshark to capture network packets for inspection by, for example, the developer of an application. To investigate the network communication of an application one can use tools that capture network packets. Sometimes an application does not work as intended, and the network communication may be one of the suspected causes. Analyzing network connections with Wireshark
