Kernel messages will appear on /var/log/messages, IIRC. And on dmesg and on the console. So I guess that, if there was any, you'd see them. > > Since my tcpdump result are not changed, it means I have to install > dhcpv6client? I need the "wide" one or another one? Can you try to capture the whole packet? Try setting a snaplen of 1500. I believe it is too early to give up on SLAAC. But you might need DHCPv6 anyway, if your router don't advertise the dns servers. See if you ain't getting malformed packets from the router, or if it's advertising, but with no actual prefixes/routes. Per RFC 7084 [0], a router should stop advertising when it doesn't have global IPv6 connectivity. But, not every manufacturer is fond of RFC's.
