![]() ![]() This should allow you to identify the protocol and physical interface through which they are connected, because you'll see both as fields of the frames which the display filter selects. If you are lucky, the actual detection of network neighbourhood takes place only after you open that window.Īfter the ghost devices show up, you would stop the capture and apply a display filter eth.addr = 00:08:15:00:08:15 (of course using the MAC address of the ghost device you are trying to identify). Finding this out is what you can use Wireshark for - on a freshly rebooted Windows machine, start a Wireshark capture on all available network interfaces first, and then go Windows Explorer -> Network. As always, this tool is available for free. ![]() ![]() It is an excellent means for verifying communication with MS/TP devices that are being accessed through BACnet/IP routers such as those available from Contemporary Controls. Or they may use IP but be connected to some other network interface of your PC than the one which looks towards the router. The BACnet Discovery Tool is a BACnet/IP application for Windows® that is easy to install and use. Too much is unknown about your network, so the fact that the home router does cannot see the MACs may be because the devices use some other protocol other than IP, so your PC can detect them using that protocol while your router cannot because it uses only IP and below. It would be best to set at least 2-4 ports as the source ports because we are not sure if which of the PCs will be able to obtain an IP address from the DHCP server. Figure 1: IP addresses and TCP port numbers of the client computer (source) and gaia.cs. Select a port (s) as a source port (s) on the JGS524Ev2 where the PC (s) is directly connected. Wireshark Lab 3 TCP The following reference answers are based on the trace files provided with the text book, which can be downloaded from the textbook website. Wireshark only lets you see data going though your own pc. Wireshark passively shows you the contents of packets it can see on the network interfaces, so unless the devices write something like "I am a refrigerator " into the packets they send, Wireshark can only assist your own investigation what those devices are. I suggest you to set up port mirroring on the JGS524Ev2 switch. No, unless you are sending data to that person directly, you cant know their IP address. ![]()
