[Devil-Linux-discuss] BIND and IPv6

[Arnaud Gomes-do-V. <Arn...@ir...>]

Hi folks,

I just upgraded one of my caching nameservers from Devil Linux 1.2.10
to 1.2.13. BIND no longer listens on my IPv6 interfaces. I didn't
change the config file (it still contains the "listen-on-v6 { any; };"
line). BIND binds to the IPv4 interfaces, but not to the IPv6 ones;
netstat doesn't show anything on IPv6 UDP port 53.

The machine has IPv6 connectivity and I tried both with and without
the net.ipv6.bindv6only sysctl.

Here is the relevant part of my config file:

options {
        directory "/etc/named";
        /*
         * If there is a firewall between you and nameservers you want
         * to talk to, you might need to uncomment the query-source
         * directive below.  Previous versions of BIND always asked
         * questions using port 53, but BIND 8.1 uses an unprivileged
         * port by default.
         */
//      query-source address * port 53;
//      allow-transfer { 192.168.1/24; };
//      listen-on { 127.0.0.1; 192.168.1/24; 192.168.9/24; };
//      also-notify { 192.168.2.210; };
        listen-on { 127.0.0.1; 129.102.2.11; };
        listen-on-v6 { any; };

        statistics-file "/var/named/named.stats";

};

Syslog shows nothing unusual; only the IPv4 binds:

Jul 24 12:43:28 src@nenesse named[1497]: listening on IPv4 interface lo, 127.0.0.1#53
Jul 24 12:43:28 src@nenesse named[1497]: listening on IPv4 interface eth0, 129.102.2.11#53
