I have operated redhat linux 7.x whcih kernel is 2.4.26.
When I run tcpdump or snort, the dmesg is seen like below.
"device eth0 entered promiscuous mode"
and when I stop tcpdump or snort, the dmesg is seen like below.
"device eth0 left promiscuous mode"
But I can't find PROMISC message when I execute ifconfig while tcpdump or
Why the result of the dmesg and ifconfig is different?
Thanks in advance.
