What is the promiscuous mode and give an example?
In promiscuous mode, some software might send responses to frames even though they were addressed to another machine. However, experienced sniffers can prevent this (e.g., using carefully designed firewall settings). An example is sending a ping (ICMP echo request) with the wrong MAC address but the right IP address.
What is Ethernet promiscuous mode?
In an Ethernet local area network (LAN), promiscuous mode ensures that every data packet that is transmitted is received and read by a network adapter. This means the adapter does not filter packets. Instead, it passes each packet on to the operating system (OS) or any monitoring application installed on the network.
What is promiscuous mode Linux?
What happens to a network card in promiscuous mode?

Why can’t I enable promiscuous mode for a virtual network card?
Well the problem is not in the network card because VMware always enables promiscuous mode for virtual interface. But the problem is within the configuration. It is not enough to enable promiscuous mode in the interface file. I had to add this line:
How do I Turn on promiscuous mode in Wireshark?
Click on Edit > Preferences > Capture and you’ll see the preference “Capture packets in promiscuous mode”. As long as that is checked, which is Wireshark’s default, Wireshark will put the adapter into promiscuous mode for you when you start capturing.
