Hello, probably the question is stupid, but I just don't get it. I have a Linux host with a bridge that contain my normal eth interface and a tap device. The br0 interface has the IP address, tap0 and eth0 are up and don't have any IP. The tap0 interface is opened and read()s the frames coming in. On a second console, tcpdump is monitoring the traffic. No traffic is actually written to the tap0 interface. # brctl show bridge name bridge id STP enabled interfaces br0 8000.a24ecad3959c no eth0 tap0 No iptables. I configured even hub-like behaviour: # brctl setageingtime br0 0 # brctl setfd br0 0 Now my question: Why don't I see any traffic apart from broadcasts? Shouldn't I see any traffic that is incoming? Because both eth0 and tap0 are in promisc mode? Thanks for the advise! Regards, Bernhard
