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.
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.

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.

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.

The acronym DFMEA stands for "Design Failure Mode Effects Analysis". DFMEA is an extension of Failure Mode and Effects Analysis which attempts to estimate the frequency and severity of each failure mode.

The network protocol that uses port 21 is FTP (File Transfer Protocol). FTP is commonly used for transferring files between a client and a server on a computer network. Port 21 is specifically designated for FTP control connections. When a user initiates an FTP connection, the client connects to the server's port 21 to establish communication for sending and receiving files. It is important to note that FTP operates in two modes: active mode and passive mode, each using different ports for data transfer.
