Relevant part of my setup are at the end of this messae for anybody who may have the same problem. BTW, I notice that link-local router address behavior is strange and inconsistant for both 'host -6' and 'dig -6' commands. host -6 example.com fe80::<rest of router address> dig -6 @fe80::<rest of router address> example.com both hangs, but in the same time host -6 example.com fe80::<rest of router address>%<iface> dig -6 @fe80::<rest of router address>%<iface> example.com works! host -6 example.com fe80::<rest of router address>%1 dig -6 #fe80::<rest of router address>%1 example.com works too. Not understanding addresses without %<iface> or %1 looks like routing problems, but I don't know where to fix it. So, I try to use nameserver fe80::<rest of router address>%<iface> (or with %1 suffix) in my resolv.conf, as result host -6 example.com dig -6 example.com (without NS specified) both hangs despite they working when exact the same NS address is given in their command lines. So, I finally decide to use my router addres from IPv6 /64 subnet (given by my tunnel). It not goes through the whole tunnel, but directly to the router. host -6 example.com dig -6 example.com both works when it exists in /etc/reslov.conf. What I don't understand why all that bad things happens with link-local router address. To be sure I test it under Win7 and it works normally. Finally, what is working: /etc/resolvconf.conf: name_servers_append=<IPv6 router address from /64 tunnel's subnet> /etc/rc.conf: rtsol_flags="-R /etc/eat.sh" /etc/eat.sh: #!/bin/sh /bin/cat > /dev/null -- http://ache.vniz.net/
