The strongest simulator of Unetlab network associates Wireshark and grabs packets.
First, to associate with Wireshark, you first need to use the Unetlab-win-client-pack.exe downloaded from the official website of unetlab. com

Second, dual-computer installation is fine.
There are two options.
Third, after installation, in the simulator, right-click the device, select capture, and then select the network card that needs to grab the package, and then you can start the packet capture.
