Promiscuous mode
Promiscuous mode is a network monitoring technique that enables access to entire network data packets and detect potential vulnerabilities.
Displays the configuration of a specific interface:
# ifconfig interface
To enable promiscuous mode on a physical NIC:
ifconfig [interface] promisc
ip link set [interface] promisc on
To identify if the NIC has been set in Promiscuous Mode:
ifconfig [interface]
// or
ip a show [interface] | grep -i promisc
To disable promiscuous mode:
# ifconfig [interface] promisc
