[...] connect(3, {sa_family=AF_INET6, sin6_port=htons(53), inet_pton (AF_INET6, "::ffff:8.8.8.8", &sin6_addr), sin6_flowinfo=16895189, sin6_scope_id=0}, 28) = -1 ENETUNREACH (Network is unreachable) Looks like another effect of bindv6only, as I have "net.ipv6.bindv6only = 1". Perhaps you have set it to 0, as it is working that way: thetis:/home/lucab# sysctl net.ipv6.bindv6only=0 net.ipv6.bindv6only = 0 thetis:/home/lucab# getent ahosts www.debian.org 2001:888:2000:12::2 STREAM www.debian.org 2001:888:2000:12::2 DGRAM [...] Ciao, Luca -- .''`. ** Debian GNU/Linux ** | Luca Bruno (kaeso) : :' : The Universal O.S. | lucab (AT) debian.org `. `'` | GPG Key ID: 3BFB9FB3 `- http://www.debian.org | Debian GNU/Linux Developer
