This issue occurs because the virtual switch does not deliver the packets to the mirroring destination port. In this scenario, the packet sniffing tool does not capture the packets between computer B and computer A. You run a packet sniffing tool on the VM. You set Mirroring Mode to Destination under the Port Mirroring section of Advanced Features in the VM's network settings. The two computers and the VM are in the same subnet. You have two computers (computer A and computer B) that both connect to the physical network. You connect the VM to a virtual switch that is connected to a physical network.

You create a virtual machine (VM) on a Windows Server 2012-based server that has the Hyper-V server role installed. Hope that helps you and happy packet hunting.Windows Server 2012 Datacenter Windows Server 2012 Datacenter Windows Server 2012 Standard Windows Server 2012 Standard More.

Even the ‘portable’ version of Wireshark isn’t entirely portable, and you may run into challenges trying to run it.Īfter some research, and testing, I’ve decided to use Microsoft’s built in packet capture commands and no, I’m not referring to Network Monitor. Each option has its own pros and cons that you need to determine on the fly for each scenario. Then I go down the rabbit hole of options: SPAN, hub, TAP, etc.

I wanted to capture packets from someone’s Windows computer, and I couldn’t install Wireshark for a variety of reasons.
