Moreover, the size of that window is usually not big, and if you maximize the window’s size, the resolution of the guest OS user interface is left the same. This fills in the switch’s CAM table, thus new MAC addresses can not be saved, and the switch starts to send all packets to all ports, so it starts to act as a hub, and thus we can monitor all traffic passing through it.After installing a guest operating system (OS) on VirtualBox, the interface of the guest OS is displayed in a windowed mode by default. Macof can flood a switch with random MAC addresses. n times Specify the number of packets to send. Homepage Options Syntax: macof -i interface Specify the interface to send on. This fills in the switch’s CAM table, thus new MAC addresses can not be saved, and the switch starts to send all packets to all ports, so it starts to act as a hub, and thus we can monitor all traffic passing through it. While this is nice for a hacker, most networks use switches, which inherently restrict this activity. This allows that device to simply collect all the data passing through a hubbed network.
However, in a hubbed network, sniffing data is very easy to accomplish by placing a network card into promiscuous mode. The data is typically rejected by all network cards, except the one it was intended for. A passive hub has no mapping, and thus broadcasts line data to every port on the device. This is the main difference between a switch and a passive hub. It actively monitors (cache) the MAC address on each port, which helps it pass data only to its intended target. The reason for this is that the switch regulates the flow of data between its ports. Macof is a member of the Dsniff suit toolset and mainly used to flood the switch on a local network with MAC addresses. MAC Flooding with MACOF & some major countermeasures
