[Bug 1092691] Re: A way to disable AAAA lookups in the resolver (again)
This is an old problem that recurs. Some time ago there was a bugfix for this - in glibc. http://jpmens.net/2011/09/28/-and-a/ https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/80571 Apparently the patch was not applied in this release (Ubuntu 12.04 LTS Server amd64). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1092691 Title: A way to disable lookups in the resolver (again) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1092691/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1092691] [NEW] A way to disable AAAA lookups in the resolver (again)
Public bug reported:
I like to known what's the way to disable DNS queries.
Already have disabled all resources ipv6.
1. Changes in grub:
vim /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT=ipv6.disable=1
update-grub
2. I'm using 12.04 LTS version (builtin ipv6 support)
grep -i ipv6 /boot/config-3.2.0-24-generic
CONFIG_IPV6=y
CONFIG_IPV6_PRIVACY=y
...
Before this i try with sysctl, but tcp6 sockets still alive.
After grub changes this solve the question - i can disable ipv6 address and
networks sockets too.
But, internal lookups stay wrong.
Some sites like www.caixa.gov.br are slow.
When i sniff my connection i can see many DNS records and server fail
Running lynx www.caixa.gov.br

I do bind changes too
vim /etc/default/bind9
RESOLVCONF=no
OPTIONS=-4 -u bind
vim /etc/bind/named.conf.options
forward only;
forwarders {
208.67.222.222;
8.8.8.8;
};
This dont solve requests.
I like to known a way to prefer ipv4 queries (A) or disable ipv6 queries.
When i'm using squid proxy the same problem occur.
To solve this i need compile squid with --disable-ipv6.
This works to Squid proxy, but i think that the best way is disable all DNS
queries.
This occur with lynx, wget and others.
