In computer networking, a device on a LAN (local area network) is only supposed to (and expected to) receive and respond to packet messages directed to that devices address. In promiscuous mode, the device will receive and maybe process packets that were directed to other device addresses as well.

Promiscuous mode can be used to study network traffic and monitor for unauthorized devices.

In early networks, all traffic propagated to every device on the network and each device such as a computer or printer only paid attention to traffic intended for it and ignored the rest. This was a result of all devices attaching to different parts of the same cable (10Base2 for the technically aware) or because a device called a "hub" allowed each device to be on its own cable but distributed the same traffic to all the devices on individual cables.

Later development produced a device called a "switch" which kept track of what devices were on which cable and only routed traffic to its intended destination. At that point, promiscuous mode was no longer meaningful, with a few exceptions, since none of the other traffic ever reached the device.

What is the difference between promiscuous mode and non-promiscuous mode?

As promiscuous mode can be used in a malicious way to sniff on a network, one might be interested in detecting network devices that are in promiscuous mode. 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. If your firewall blocks all ICMP traffic, this will be prevented.


Difference between promiscuous and non promiscuous mode?

promiscous mode is one in which all the packets are sent to a computer and not only those which are addressed to it. in a non promiscous mode only those packets are send to the computer which are addressed to it.

What is the difference between promiscuous mode and inline mode?

Inline is used to look at a specific location such as between two routers, where as promiscuous mode captures traffic using a capture device such as a hub or switch, this way all traffic that goes through the device is monitored.

What is promiscuous mode in Ethereal?

For a message to send out, it has to address which Mac address to send. If the message I received doesn't not match with my MAC address then my network interface will drop the packet completely. If your network is on promiscuous mode, then your network interface will not drop the message. It is good for packet sniffing. I hope this helps.
