I have question about promiscuous mode.in a lan nework if one of the node is having a lan card set in ...?
...promiscuous mode then
it starts sniffing all the data packets flowing across the lan this
can b harmful.in a lan nework if one of the node is having a lan card set in promiscuous mode then it starts sniffing all the data packets flowing acrossthe lan.we will send arp packets in lan with a destination address of which no node exist in the lan.
in promiscuous mode the node wil accept those packets & wil respond toit.in promiscuous mode all the packets in lan are accepted irrespective of their destination address.as soon as a node wil respond we can get 2 know that an NIC is in
promiscuous mode or not.there are 2 type of filtering done here:
hardware filtering & software filtering.
in hardware filtering the destination address of packets are atched wid hardware address.& hence on this basis filtering is done.
but in promiscuous mode hardware filtering is not done at
all..........so software filtering is done.
