[Bug 1092691] Re: A way to disable AAAA lookups in the resolver (again)
I have the same problem. After trying very hard to disable ipv6 completely (in order to get rid of EXTREME LONG download times for chromium git and having an ISP that does not support ipv6), my interface *STILL* has an inet6 addr and the resolver STILL does look ups :(. This is insane-- why is there is no way to disable ipv6?! eth0 Link encap:Ethernet HWaddr c8:60:00:c3:37:1c inet addr:192.168.0.14 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::92f9:ecc1:82d2:1d3/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:27837071 errors:0 dropped:0 overruns:0 frame:0 TX packets:24277886 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:13897890845 (13.8 GB) TX bytes:3590197010 (3.5 GB) Dowloading 13.8 GB of repositories (many of them) took me two days; should be possible in an hour. -- 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

Same problem here... and now it's 2017. My ISP is not going to support ipv6 for years :(, and in the mean time it would be nice if connections to servers with both, ipv4 and ipv6 (like google) I wouldn't run into a 2 minute timeout all the time :/. -- 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

Yes, I do have the same problem: Disabling IPv6 with kernel parameter does not work. Changing configuration in /etc/gai.conf does not work either. requests are still resolved on IPv4.

Have the same problem. Initial connect to a internal SSH server feels like connecting via 56k modem... Sucks! Disabling IPv6 with kernel parameter does not work.

[Bug 1092691] Re: A way to disable AAAA lookups in the resolver (again)
** Description changed:
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
+ 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
- ...
+ 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
