Ok. I am pleased to say this has finally been resolved.

FWIW, I spoke too soon, I can only imagine the couple of sites I tested must have been cached by something else hitting 'em on login (ubuntu.com perhaps due to ubuntu one, and local dev site due to a cron).

[Bug 417757] Re: [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups
I've noticed multisecond delays since switching to Lucid. I have two boxes here. Identical resolv.conf entries for local DNS. The Karmic machine responds instantaneously, the Lucid one takes several seconds for uncached addresses. If I run: ltrace wget -O/dev/null http://domainwebserver/url/ And I haven't hit this webserver on our domain recently, I can see it hang for several seconds on getaddrinfo. It then hangs again resolving the full name (domainwebserver.ourdomain.local) if a redirect is issued. So far I've tried: disabling ipv6 in sysctl.conf and as kernel param in grub. replacing the hosts line in nsswitch.conf w/ only files dns (the full hosts line in lucid works fine in karmic). Uninstalling libnss-mdns. Despite all this I repeatedly get hangs on getaddrinfo - other things respond quickly, such as dig and nslookup. The only improvement I've experienced (and this was also new to Lucid) was that after I removed: mdns4_minimal [NOTFOUND=return] I no longer got complete failure to perform lookups. That line appears to work fine in Karmic, with the exact same servers. I've also tried adding or removing wins from the hosts line in nsswitch.conf in case that was why Karmic was fast. No difference. Whether wins was there or not, Karmic remained fast, and Lucid slow. -- [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups https://bugs.launchpad.net/bugs/417757 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

As you have both a working and a not working configuration, this makes you the perfect candidate for giving more details on that problem. Please give more details: What *exactly* is the problem you are talking about? Is it a problem while resolving a name to an IP address? (DNS) Is it a problem connecting to the other host? (Syn, Ack, etc.) Or is it a problem while beeing connected in some kind of TCP session? (bandwidth, etc.) If you are not sure, please use wireshark to monitor your connection. (All phases above are visible there and their timing.) Please do so on the working and not working system and report the difference. But since you are pretty sure it has *nothing* to do with IPv6, it is almost certainly another bug. So *please* open a new bug and give only a pointer to the new bug here. Hopefully this will finally bring some light on the cause of that issue. :) -- [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups https://bugs.launchpad.net/bugs/417757 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 417757] Re: [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups
Sorry to add to the noise a bit, but I just want to get the scope of this bug clear. I certainly have *a bug* but I can't figure out if it is this one or not. In the description, it says If disabling IPv6 or using good DNS servers like openDNS fixes the problem, you are not dealing with this bug. Does not dealing with this bug mean you have another bug which is unrelated to this, or does it mean you have this bug, but that isn't a valid fix for it. Maybe we can get this text cleared up to avoid all this confusion about who has the bug and who doesn't. It also says Routers which do not repond [sic] to this cause the lookup to take 20 seconds The latter quote seems to imply that the bug will appear for certain DNS servers (e.g., a router), but not others (e.g., proper Internet DNS servers). Therefore, if using a good DNS server like openDNS fixes the problem, why am I not dealing with the bug? The bug only shows up on certain DNS servers; changing my DNS server is a workaround, but surely it implies I have this same bug. I have the iiNet BoB router, which is giving me 20 second DNS lookup delays. Changing my DNS settings (in resolv.conf) to a public DNS server (in this case, using my ISP's DNS server) fixes the problem immediately in all apps.

Ok, you have a bug. But are you sure it is a bug in Ubuntu? Do you have any other OS working correctly with the same router? Please have a look at your network traffic. (Wireshark is nice for this.) *This* bug goes like this: Ubuntu: Hey router, what is IPv6 address of example.com? Router: (ignores that question and does not answer at all) Ubuntu: (waits for an answer for some seconds and finally...) Ubuntu: Ok, I assume you don't have one. Then do you have any IPv4 address of example.com? Router: (answering immediately) Sure, here you are. With disabled IPv6 Ubuntu does only ask for a IPv4 address and the problem is no longer visible. If your bug does not go away after disabling IPv6 it is *not* this bug. Please investigate where your delay comes from. Is it really the router not answering at all? Does it really involve IPv6?

My comment wasn't really to add to the bug report, but mostly to try and clarify the bug's description.

It was working fine in Karmic with the exact same setup (same laptop, same router). It works fine in Windows XP. It still works fine with any other router. So it's clearly a combination of this router and Lucid that is a problem *for me*. I'm not asking for help here (since I've already worked around the issue), just trying to figure out if I am having the same bug (so I can be useful, and provide you with socket dumps) or if it isn't (so I can get out of your hair).

Routers which do not repond to this cause the lookup to take 20 seconds (until the IPv6 query times out). *** PLEASE DO NOT COMMENT ON THIS BUG unless you have something constructive to say.

Please let those that actually know what they are doing concentrate on fixing this bug from now on. *** + + If disabling IPv6 or using good DNS servers like openDNS does fixes the + problem, you are not dealing with this bug.

Conversely, having the same symptoms (and as much as anyone has shown here since the fix for this bug was verified is that their network is slow, which is a very broad symptom) doesn't mean this bug isn't fixed. You say you've disabled ipv6. How did you do this? Do you have network traces showing that eglibc is still sending the wrong DNS queries? I have personally retested the karmic version of libc6 in response to your message here. The bug described in this report is fixed - a system with no routable ipv6 addresses will not generate DNS queries with libc6 2.10.1-0ubuntu16 installed. So whatever problem you're seeing should be tracked in a separate bug report. And don't tell me it is fixed because otherwise i wouldn't be posting here don't you think ? No offense, but experience shows that with high-profile bugs where the symptom is described in such general terms as is the case here, users *very frequently* follow up when the problem they're experiencing has nothing to do with the bug report in question. Really c'mon guys, why it is so hard? If it is fixed for you, nice! congratulations! now move along, we have people here that still have problems (including myself). If it's fixed for them, then it's almost 100% certain that people still experiencing problems have a different bug. Different bug - different bug report. (If you're reading this because you *did* file a separate bug and your bug was marked as a duplicate of this one, then that was a mistake and we should correct that status.

[Bug 417757] Re: [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups
@Ricardo Fernández As I mention above, in my case, after disabling IPV6, I still had the same symptoms. Terribly long delays making any kind of network connections (all wired). I noticed here that it seemed to be related to making more than one network connection at a time. Based on forum posts elsewhere, I upgraded the firmware on my D-Link 707 switch/firewall and then suddenly all network problems disappeared. Of course, CentOS, WinXP, Win2K and Ubuntu 8.04 never had a problem with the router, so I'm not sure why this fixed the issue. But unfortunately, I've wasted too much time on Ubuntu 9.10 problems. It's been by far the buggiest least reliable error prone distribution I've ever come across (been developing software using Linux professionally since early 1993). This is also the very first time I've been unable to find good information on how work around issues that come up despite having put in some serious effort. (Sound, anyone?) It's open source after all and I've offered to help track these issues down, but got no useful response. So I've bailed. I'm running Fedora Core 12 now.

@Ricardo: Amen. Ubuntu is a nice end-user-friendly distribution. I respect what they are trying to do. But there comes a point where bailing is the only sensible option. Fedora Core 12 works like a champ. Networking works. Sound works. Package management works. Java works. OpenOffice works. etc. And I've noticed the same thing you have. The quality of technical posts for Fedora Core is definitely much higher than what I've seen in Ubuntu. I'm not sure why. It's all Linux after all. I guess Fedora attracts a more technical crowd and they seem, at least for the moment, to be much more focused on solving problems. -- [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups https://bugs.launchpad.net/bugs/417757 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 was wondering something, If a Fix was Released, and if it doesn't work (as reported by almost all users since the release), what we should do? Open a new bug ticket? I'm not changing the status or anything, but it is kinda lame that the status can't be reverted because the fix doesn't work at all. After the Fix was Released no one at Ubuntu have been trying to reach the users to see what is going on, they just check that the bug is fixed and thats it; is there no need to check the feedback? This Bug is _NOT_ fixed at all, check the comments from the people, it didn't do the job, they are still delays on resolving names and the browser takes few seconds before opening webpages, this same is happening on 10.04 right now. I guess this bug will be like the VNC client on Ubuntu (the one installed by default on gnome, vinillo), 4 releases of Ubuntu and still doesn't work at all, no one can even use it, and still there was a Fix Released. *sigh* -- [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups https://bugs.launchpad.net/bugs/417757 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

Open a new bug ticket? No, you should try to determine if the problem you are experiencing is the same problem as the problem described in this bug. If you still have issues (which you shouldn't have, since *this* bug is fixed), try to debug and find which problem you are experiencing. This problem is about trying to get -records on machines that don't even have any IPv6 connectivity. (devs, please correct me if needed). If you tcpdump your interface, and see no -queries, this bug is not your problem, but there might be another problem. So, if you still experience issues. Try using wired networks instead of wireless (I myself have crappy wireless performance with Karmic and a Linksys interface), tcpdump your interface to see what happens.

Re: [Bug 417757] Re: [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups
This bug is about Ubuntu dealing with bad DNS servers that don't understand (IPv6) queries. Before claiming this isn't fixed, please make sure that bad DNS servers are in fact the issue. If disabling IPv6 lookups in Firefox fixes the issue, then you are dealing with this bug. If switching to good DNS servers like those of openDNS or Google fixes the issue, then you are dealing with this bug. If switching from wireless to wired* on the same LAN* fixes the issue, then you are not dealing with this bug.

This bug is far from fixed, there was a fix committed but it didn't do anything, they are still lot of people complaining (including myself of course), and it seems it still happening in 10.04. I don't know how you guys are testing this, but so far, I'm still getting DNS delays and the browser takes a lot sometimes to resolve and open a webpage. -- [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups https://bugs.launchpad.net/bugs/417757 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

Re: [Bug 417757] Re: [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups
I have a wired connection. And I recently changed my modem to a much newer one. I've been having issues recently, which seemed to spawn from an updated vbox. I have ubuntu running as quest on windows 7. After the update of vbox, my connection would be very strange, at start up of Firefox, everything would load. After couple seconds or so, the connection would grind to a halt. Recently, I activate IPV6 on Firefox, and the problem has gotten much much better, but not completely alleviated. Some pages are constantly trying to load, but never get there. But thats much better than before. Before I switched the flag in Firefox, pretty much all the pages would be stuck in load mode, it was so frustrating. Specs: Windows 7 with ubuntu guest through vbox wired connection straight to the modem, nothing in between. Windows 7 seems to work fine Ubuntu seems like there are some issues still.

[Bug 417757] Re: [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups
@Laurent yes. /ALL/ network access regardless of application is affected. Please re-read the report I wrote. Yes, this has nothing to do with the IPv6 DNS lookup problem. IPV6 record lookup was one issue that would cause the slow connections so many people are experiencing. My point is that while the IPv6 lookup issue has been resolved, it is not the only cause of the slow dns lookup/connection symptoms people are experiencing. As I have said, IPV6 is /disabled/ on my machine via grub. IPV6 is disabled in firefox. IPV6 IS NOT THE SOLE REASON FOR SLOW DNS AND NETWORK CONNECTION IN UBUNTU. i have verified this here. Maybe it should be listed as a separate bug, but none of the other bugs I have found (of which there are many) seem to match the symptoms I'm seeing here exactly. Slow dns lookups. DNS lookup failure 30% of the time or so. Connection failure 30% of the time or so. Extremely slow net connectivity over a wired connections. I've tried every combination of work around I could find on the net to no avail. Then I upgraded the firmware on my DI-707 router and suddenly the problem disappears. The confusing thing is that Ubuntu 8.04, WinXp and EVERY SINGLE DISTRIBUTION BEFORE had no issue with this router. It seems to be restricted to recent 2.6 kernels. I had read somewhere, I'm sorry I have forgotten where, that there was some TCP/IP standards issue that someone had decided to implement too strictly in recent kernels which caused connections through many legacy routers/switches/firewalls to fail (which is why I tried the firmware upgrade). At this point, for me, the problem seems to be solved, but I have the feeling that there are many Ubuntu users out there that are still suffering from slow/failing dns lookups and the IPV6 issue does not explain all of them. There is still some network level problem. But like I said, the firmware upgrade on my DI-707 seems to have worked around whatever problem Ubuntu has. I'm reporting this in an attempt to be helpful; too often in my own software business customers who are running into trouble with our software simply don't report their experiences so we have no idea that there's a problem. -- [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups https://bugs.launchpad.net/bugs/417757 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 417757] Re: [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups
@Laurent Yes, I was thinking the same thing since it's now fixed for me. However, if you do some searches, even in the Ubuntu forums I think, you'll find dozens if not hundreds of posts from people saying they turned off IPV6 but still had slow lookups/connectivity. There was one thread somewhere where it was mentioned that this was due to Ubuntu/Linux now implementing some standard (I don't know which one) more rigidly than many router/switch manufacturers. That was the reason I thought to upgrade the firmware in the DI-707.

[Bug 417757] Re: [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups
@Laurent Ok, I spent some more time researching this, playing with various scenarios. 1. Fedore Core 12 running in VMWare exhibits the same problem as Ubuntu 9.10 running natively. 2. WinXP running in VMWare does /not/ exhibit the problem. 3. Cent OS 5.4 running in VMWare does exhibit the problem. Something I was not expecting. 4. Ubuntu 8.04 did /not/ exhibit this problem. It started with 8.10 and appeared to be much worse in 9.10. Based on some discussions that I remember reading (but no longer have a link to) I decided to try to upgrade the firmware on my DLink 707 firewall gadget to version 2.57 from version 2.51. It's too early to tell for sure, but my initial feeling is that network performance is much improved. My standard test of loading multiple large pages simultaneously is not causing the problem. If this turns out to be the fix, the question would be why did Ubuntu 8.04 work flawlessly and later versions have problems? -- [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups https://bugs.launchpad.net/bugs/417757 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 417757] Re: [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups
From what I am observing here, the IPV6 problem is not the sole cause of slow lookups and connection speed. Despite turning off IPV6, running my own name server (even a local caching one), modifying /etc/nsswitch.conf, tweaking settings in ethtool, etc. etc. etc. I still get stalls and failed connections so often that the distribution is on the verge of unusable. To reproduce this problem open 15 tabs or so in firefox. close firefox. Open it again and open another network app like Thunder bird at the same time. More often than not many tabs will fail to load and you'll get a failed to connect error from Thunderbird. As has been reported, this does not happen, for instance, in WinXP running in VMware on the same physical machine. I am behind a D-Link DI-707 switch. Unfortunately, it looks like I am going to have to bail on Ubuntu. It's too bad.

[Bug 417757] Re: [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups
I can confirm that there is something else, beyond IPV6 lookups, that is causing timeouts. Kubuntu 9.10 with libc6-i686 2.10.1-0ubuntu16 (i386) which, if I'm not mistaken, contains the IPV6 fix. Dell Nseries desktop box. Completely stock. Using fixed IP behind a D-Link 707 consumer grade firewall. DNS server running on a CentOS 5 box on the other side of the firewall. IPV6 disabled in /etc/default/grub using GRUB_CMDLINE_LINUX_DEFAULT=ipv6.disable=1 quiet splash IPV6 disabled in firefox as well. Regardless of whether I use a local caching nameserver, pdns-recursor, or a name server on a CentOS 5 box, the timeout phenomenon is the same. From a gut feel point of view, I'd say it's worse when using the local caching nameserver. Running WinXP in VMWare Workstation 7 on the same physical machine with no timeouts. (i.e. While it's timing out in firefox I switch into XP and pull the same page. Comes up instantly.) My feeling is we're dealing with some kind of race condition in the resolver library because it happens when doing a number of simultaneous DNS requests. Open 20 or so tabs in firefox to various websites with varying load times. Close firefox. Reopen firefox and at the same time open Thunderbird. In this scenario Thunderbird will timeout 100% of the time as will the majority of tabs in firefox. It's intermittent. In FF, I can have one tab that's loading and other that's timing out. Sometimes it will pull the main html page but timeout on graphics or CSS. I would like to be able to run Kubuntu instead of having to fallback to CentOS 5. I am willing to lend a hand to track this down if you would like to give me some tests to run.

[Bug 417757] Re: [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups
This problem is not fixed on my computer, unfortunately. I'm a first time poster here - been watching this bug for a long time. It appeared to be fixed for a day or two, but I still have the long delays on page requests. Also, I've tried downloading large files via firefox and I've also been experiencing delays in the start of the downloads, as well as long interruptions. Watching this on the system monitor confirms, when this bug acts up, there is zero incoming transmissions via wireless. The only work around I've been able to get to work is to open a new window in firefox, and hit stop + refresh until it 'unlocks' itself and the incoming transmissions restart. Also, I don't seem to have the eglibc package installed on my version of Karmic (Desktop, 64 bit). Is this embedded in another package? I've found eglibc-source in the repos - am I supposed to install this? Sorry for the questions, but this has been a most frustrating bug and I'd like to see some resolution.

To clarify my terminology per Martin Pitt, I should have said that there are no longer any delays when browsing, using Rhythmbox and checking for updates.

Downloads are about 100kps were the very same machine (Fujitsu Siemens Amilo A notebook) running Windows XP does about 600kps. This is totally unrelated. The symptom of this bug is that it takes some 10 seconds to establish a connection (due to slow name resolving).

I suspected user (as in me) error after my report yesterday.

Speeds seemed normal and similar to what I was seeing using 9.04.

I' ve been experiencing intermittent slow browsing in Firefox 3.5 with IPv6 enabled. It's much better than it was but there are periodic 3 to 4 second delays in loading web pages. Additionally, preset radio stations in Rhythmbox sometimes take 3 to 7 seconds to load. Update manager is slower to start as well. When I switch over to Jaunty (with Firefox 3.5 installed) on the same machine, I see none of these issues. -- [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups https://bugs.launchpad.net/bugs/417757 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 use Karmic, and to overcome the bug I used the four numbers IP of my FAI SMTP I just checked that returning to the normal smtp name I obtain a correctly fast response. Also for internet browsing I had disabled the ipv6 in the configuration of the wifi lan. I just activated it again, and checked some pages: seems normal.

I tested the karmic-proposed package on my work machine, however, I'm still having intermittent issues with this. Since this is a work machine, I'm at the mercy of our IT department as far as routers and DNS resolution goes. I've disabled all workarounds, installed the new package and rebooted. It worked for about five minutes before going back to the same behavior I was seeing previously. All throughout this bug report, a lot of people (developers, I'm assuming) have commented that the routers are broken and it shouldn't be on Ubuntu to fix the problem. I'm sorry, but if I go from a working version of Ubuntu (Jaunty) and upgrade, I expect everything to work equally as well, if not better, than the previous release. -- [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups https://bugs.launchpad.net/bugs/417757 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
