So, what about GRUB_CMDLINE_LINUX=ipv6.disable=1 in Lucid? Doesn't it work anymore?

[Bug 313218] Re: IPV6 causes slow internet access
Thanks. What seems to be happening now is that your system does a perfectly ordinary IPv4 A record query for bugs.launchpad.net to 192.168.2.1 (the first nameserver in /etc/resolv.conf, which I'm guessing is your router), gets no reply for five seconds, and then retries successfully to 68.87.74.162. In other words, there is still a problem, but it no longer appears to be anything to do with IPv6. More to the point, I don't think it's anything that glibc can do anything about either; it's just doing what it's told to do. At this point I feel comfortable in saying that you should fix this by way of a configuration change. For example, if 192.168.2.1 is simply a broken DNS server and you don't really want to use it, but your router always sends its address out via DHCP, you could edit /etc/dhcp3/dhclient.conf and use the directives described in the OPTION MODIFIERS section of the dhclient.conf(5) manual page to override it: for example 'supersede domain-name-servers 68.87.74.162 68.87.68.162 68.87.73.242;' if those addresses are stable. ** Changed in: glibc (Ubuntu Jaunty) Status: Triaged = Fix Released -- IPV6 causes slow internet access https://bugs.launchpad.net/bugs/313218 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I am also having what I am guessing is this problem. It happened around the time of Jaunty Alpha 5's release as my Internet was unaffected earlier.

The router is fairly new (DLink DIR 655 Wireless N Series) so I'm unsure why it would not be able to switch between IPV6 and IPV4 as the other commenter noted regarding his Belkin router.

[Bug 313218] Re: IPV6 causes slow internet access
I'm wondering if I'm having a similar issue. I'm having slow internet access when I set a static IP. If I use DHCP it works great. I have this Ubuntu 8.04 Server directly connected to a comcast router. It has 5 static IPs. I use these all the time so I just set the static ip in /etc/network/interfaces and it normally works. I get 1.5mb down. Right now if I set the static IP I get about 300k down. Then if I change my interfaces file to iface eth0 inet dhcp and reload networking I get my 1.5mb down. I have IPV6 disabled. I use the same DNS with each test. If I plug my laptop running windows directly into the router I can get 1.5mb down with DHCP or static so I don't think it is a ISP hardware problem.

However if do wget -4(which forces ipv4) it does work. Further, if I switch the DNS server in /etc/resolv.conf to a ipv6 capable DNS server, then wget works fine without needing the -4 switch. Therefore, it appears very likely to not be a router issue, but to be specific DNS servers not supporting the IPv6 requests coming from Ubuntu. I would just like to add my support for the call that there is a simple way to disable ipv6 for those of us who have no need for it. -- IPV6 causes slow internet access https://bugs.launchpad.net/bugs/313218 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

it is probably both a problem with some routers and some dns servers , on my system bypassing the router and plugging directly into my cable modem eliminates the problem for me . the problem is that some routers and some servers are not ipv6 capable at this time so we need to be able to disable it . -- IPV6 causes slow internet access https://bugs.launchpad.net/bugs/313218 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 313218] Re: IPV6 causes slow internet access
Curiously, I can't reproduce this using any of the applications I've tried. While I do have some level of IPv6 networking, I've deliberately turned it off for this test, and in any case I'm testing at the tcpdump level; I can clearly see the A and queries going out in parallel, rather than what sojourner was seeing which was the query going out and then a long timeout. That means I need to figure out what's different about our environments. One useful place to start would be an strace of a fairly simple client such as w3m.

[Bug 313218] Re: IPV6 causes slow internet access
Although I have not investigated the network traces in this bug in any detail, people investigating it (particularly JoeKlein, who touches on similar issues) may like to bear in mind that we used to have a problem along these lines in Ubuntu, but adjusted glibc's resolver code in order to avoid it. As a result you may find that old documentation or documentation based on other systems is not as applicable as you might think at first glance. The original change was: glibc (2.5-0ubuntu13) feisty; urgency=low * debian/patches/any/local-ipv6-sanity.diff: Only do lookups if we have an interface with better than link-local addresses available. -- Tollef Fog Heen tfh...@ubuntu.com Tue, 3 Apr 2007 14:11:26 +0200 In the current glibc source package, you'll find that change in debian/patches/any/local-ipv6-lookup.diff. On general troubleshooting principles, if you are encountering a problem with lookups happening when true IPv6 connectivity is not available (as should be the case with non-IPv6-capable routers or ISPs), then I would strongly advise starting by figuring out if the behaviour described in this patch has regressed. -- IPV6 causes slow internet access https://bugs.launchpad.net/bugs/313218 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

With regard to the specifics of this bug report, we would prefer, if possible, to make any necessary further fixes to glibc and other similar resolver code rather than returning ipv6 to its previous modular state in the kernel. Remember that this has only happened in a development cycle, which is a good time to try to iron out these kinds of bugs that may affect several packages. sojourner (or anyone else who is actually experiencing a *real* IPv6 problem; Shirish does not appear to be experiencing such a problem and as far as I can see is simply asking for help configuring IPv6), could you please post the output of 'ifconfig'?

no that was a period where nothing was loading , after my initial pages loaded I paused to take a peek at what had been written so far and then loaded a couple of more pages . -- IPV6 causes slow internet access https://bugs.launchpad.net/bugs/313218 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thank you for reporting this issue. Please provide more details on why it seems slow. Where do you see the delays? How is your system and network configured? How can this be reproduced for testing? ** Changed in: linux (Ubuntu) Status: New = Incomplete -- IPV6 causes slow internet access https://bugs.launchpad.net/bugs/313218 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 313218] Re: IPV6 causes slow internet access
network is configured by network manager as open (no encryption ) network is wired with a belkin f5d7230-4 router and mororola cable modem , ISP is comcast (us) , system is jaunty ,currently instaled with daily alternate amd64 destop dated dec 31 08. I can tell ipv6 is the problem because prior to kernel 2.6.28-4 with ipv6 disabled, website access was fast and loading was fast and smooth, with ipv6 enabled there was a long delay 10sec accessing any web page and loading was slow and choppy ( burst of data pause burst of data pause finaly loads) this was evident in all browsers FF 3.05,3.1 (PPA),3.2 (ppa) , Opera 64bit 9.62 and 10 beta (builds 4103 and 4116) , epiphany , dillo, seamonkey and galeon . connecting to a different network (wireless) with a different router the problem dissapears , connecting with the original network with out the router and connected directly to the cable modem the problem dissapears , these results are duplicated with another system running ubuntu 8.04 (lts) upto date . In my case it appears to be the router that is the bottleneck but there are reports in the forums and elsewhere about the same thing with noncompliant ISPs . You will not be able to duplicate this problem unless you have a noncompliant router or ISP , please feel free to request any tests I can perform for you . -- IPV6 causes slow internet access https://bugs.launchpad.net/bugs/313218 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 313218] Re: IPV6 causes slow internet access
I think my problem is related. Since updating to jaunty I cannot use my default dns server (my router) and I have to change my resolv.conf to use my isp's resolv.conf (my other computers running intrepid and other OSs have no problem with my router's dns handling).

Regardless of the router slowness: the issue is that the choice to disable it *apparently* is no longer there. I currently have daemons listening on a non-existent IPv6 network. Likewise if I had IPv6, the choice to disable IPv4 would be appreciated.

Re: [Bug 313218] Re: IPV6 causes slow internet access
All, I am unsure that it would be considered a bug, instead, a set of decisions, based on your environment (routers, hosts, ISP, security) and a set of configurations. I am working on a decision tree and documentation to help fix this problem. Please give me a few weeks.

[Bug 313218] Re: IPV6 causes slow internet access
in my opinion it is a bug and also a regression in that it causes problems for people with some very common hardware . atleast here in the US (the only country for which I can speak) belkin is a very well known and widely available brand and my model is their low end and low price model . It has functioned very satisfactorily up to the point when IPV6 was built into the kernel, and by failing to resolve this problem we will essentialy be locking out many potential users . the same appplies to non compliant ISPs since here in the US ,broadband is often only avaiable from your monopoly phone company or monopoly cable company . -- IPV6 causes slow internet access https://bugs.launchpad.net/bugs/313218 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 313218] Re: IPV6 causes slow internet access
Sounds like we need to get to the bottom of what is causing the timeouts. Hopefully it can be resolved in a way that is not slow, and also allows both ipv4 and ipv6 without requiring manual configuring or disabling by the user. I expect that it would help to compare tcpdump traces on your host accessing something that demonstrates the problem Both with and without the delays, but with all else as similar as possible. But perhaps the procedure Joe is working on incorporates that, or is even nicer. -- IPV6 causes slow internet access https://bugs.launchpad.net/bugs/313218 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 313218] Re: IPV6 causes slow internet access
how do I do a tcpdump trace ? I can eaisly configure my system to have or not have the delay , simply unplug a cat5 cable and enable a wireless network or if you want it done on the same box/router/isp it will have to be done under an earlier kernel because in 2.6.28-4 ipv6 is not loaded as a module and cannot be disabled . -- IPV6 causes slow internet access https://bugs.launchpad.net/bugs/313218 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
