My goal is to have an equivalent to "arping -U <my-ipv4-configured-on-eth0> -I
eth0" to do a "Unsolicited ARP mode, update your neighbours".
When I run "ndisc6 <ipv6-of-a-neighbor> eth0" I get the response. But when I
do a "ndisc6 <my-ipv6-configured-on-my-eth0> eth0" I get the "Timed out".
Maybe I don't understand it correctly =(

Thanks! I like the "ip" tool more and more... =)

I've installed "libpcap0.8-dev" and "libnet1-dev" (debian squeeze). Maybe I
miss another -dev package, but I can't find which one is missing =(
Cheers,

PS: I thought I should cleanup the list and write a new message to not
"penetrate" the thread "hosting for 1 powersupply with lan port" anymore =)
Sorry for the inconvience and for switching the language in the thread.
