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 =( > 'ip nei' can be used to look at the current entries, it does not allow > for sending a ND solication, but effectively one can also do: > > in one shell: tcpdump -i eth0 icmp6 > in another: ping6 -i eth0 <address> > > should give you the packets too unless it is cached, but then you can > remove it with 'ip nei flush ...' to force it to be cached again. > > Note that 'ip -4 nei' is effectively showing the ARP tables, while 'ip > -6 nei' is for the ND based information. Thanks! I like the "ip" tool more and more... =) > > gcc -o ndping ndping.c -Wall -lnet -lpcap > > ndping.c: In function ‘callback’: > > ndping.c:65: error: ‘LIBNET_ICMPV6_NS_H’ undeclared (first use in this > > function) > > You need to install the libnet headers for that to work. 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, Tobias 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. -- Nine Internet Solutions AG, Albisriederstr. 243a, CH-8047 Zuerich Support +41 44 637 40 40 | Tel +41 44 637 40 00 | Direct +41 44 637 40 13 Skype nine.ch_support _______________________________________________ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
