Hi all! Recently I was testing a 6to4 setup involving a gateway and a laptop behind the gateway. I installed radvd on the gateway and configured it to announce the tunnel running over eth1 on interface eth0. On the laptop, I just modprobed ipv6 and watched ifconfig's output to see it it automatically got a scope:global address. As it didn't get one after a minute or so, I started tcpdump in a second terminal to check if radvd was in fact advertising the tunnel. Well, big was my surprise when right after the next advertisement the global address appeared, and it was even bigger when it disappeared again 5 minutes after I had terminated tcpdump. Then I did another check with ifconfig eth0 promisc; sleep 60; ifconfig eth0 -promisc and the behaviour way exactly the same. It seems like the kernel can see the router advertisements only if the interface is in promiscuous mode. Is this by design, is it just not finished yet, or am I missing something completely here? Would the tcpdump output be helpful?
