Well Mr Fleming it takes care of the problem until someone figures out the real problem. Except that it doesn't and you haven't read a single word I've written. Turning off IPv6 lookups for one application doesn't solve the issue at all, just acts as a placebo at the absolute best. Your turn off lookups for /IPv6 records so-called solution is in the long term worse than useless - and I'm being quite charitable here. The OP has loaded the IPv6 modules - this will ready the kernel for IPv6 traffic and allocate link-local IPv6, but does not connect the host to the public IPv6 network out of the box. This is normal behaviour for most if not all Linux distributions released in the last few years and even Windows XP and later for that matter. The workstation I'm sitting at for instance (F11/x86_64) has that precise configuration (my servers are fully IPv6 capable) You will get a globally routable address via a 6to4 tunnel (see the documentation reference I wrote earlier) or a tunnel broker like Sixxs or Hurricane Electric (he.net) - some network providers/ISPs even offer native connectivity; it never hurts to ask. As for the OP's issue I am very sure that it is a more general DNS resolution problem, given that (for example) mirrors.ucr.ac.cr has no record, and the single A record pointing to 163.178.174.25 from where I sit. If the OP is seeing differently then it confirms my theory.

Any ideas? Regards, Clodoaldo This IPV6 thing is a problem in FC11 , FC10, everyone of the of the 12 boxes I have setup in FC11 I have had to do the below setup to even connect to rpmfusion.org. 1. Q: Networking (or DNS) seems really slow and fails often (Updated 2 January 2009) A: If Fedora 10's networking seems slow or you get frequent network connection failures (when other Fedoras or other OSes were working just fine on your machine), then you're probably hitting this bug. Here's how you can work around it: 1. Open a Terminal. 2. Become root: su - 3. Make sure that the dnsmasq program is installed (it usually is, by default, in Fedora 10): rpm -q dnsmasq If that says package dnsmasq is not installed, then you need to install dnsmasq, by running the following command: yum install dnsmasq 4. Now, you have to find out which network interface your machine is using: route -n You'll see some output that looks like this: Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0 0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0 The eth0 there (the furthest bottom-right text in the output) is the name of the network interface I'm using. Yours might be eth1 or something totally different. Just remember it for the next step. 5. Now create a file called /etc/dhclient-your network interface.conf. For example, if your network interface is eth0, the file would be called /etc/dhclient-eth0.conf. You can create the file with this command (assuming your network interface is eth0): nano /etc/dhclient-eth0.conf Then make this the only line in the file: prepend domain-name-servers 127.0.0.1; And then save the file and close it (Ctrl-X then Y). If you have both a wireless and a wired network connection, you will have to do this step once for each of them. 6. Now start dnsmasq: service dnsmasq start And make sure that it will start every time your computer starts: chkconfig dnsmasq on 7. Now restart your network connection: service NetworkManager restart And now things should be as fast as normal again. You might have to restart the programs that you're running for them to pick up the changes that NetworkManager made when it restarted. 2. * IPv6 You might notice that your browsing through Firefox is a little slow on Fedora 10. This is because Firefox 3 has enabled by default IPv6 which causes Firefox to first resolve an IPv6 address and after the connection fails it switches to IPv4. To change this setting type: about:config and in Filter box type: network.dns.disableIPv6 Right click on it, select Toggle and change its value to true. Restart Firefox and you are ready!

In instead I disabled it hoping it would help. I answered it before and I will say it again. I don't care about IPv6. Not at all. I just want my machine back to what it was before, that is, connections to whatever needs it.

When I set network.dns.disableIPv6 to true I can see all IPv4 in Wireshark. This is Fedora 10 64. While it is easy to solve it for Firefox there are many services that can't connect even if I disable IPv6 in the system. One symptom is Yum has to try repetitively until it finds a suitable host: http://mirrors.ucr.ac.cr/fedora/releases/10/Everything/x86_64/os/repodata/repomd.xml: [Errno 4] IOError:urlopen error (-2, 'Name or service not known') Trying other mirror. Another is that the weather applet and fold...@home can't connect. When I disable IPv6 in the system the applet connects but Yum behaves the same (multiple tries) and still fold...@home can't connect.

Any ideas? Regards, Clodoaldo This IPV6 thing is a problem in FC11 , FC10, everyone of the of the 12 boxes I have setup in FC11 I have had to do the below setup to even connect to rpmfusion.org. Turning IPv6 related DNS lookups off (even in firefox) is NOT fixing the issue - will people please stop posting this utter trash as helpful information please? There's enough myths around IPv6 as it is and this isn't helping. (plus such people might want to look at how the getaddrinfo() call works..) The problem is the OP has *enabled* IPv6 - loaded the module etc. but hasn't *configured* it. It won't magically set up a tunnel / 6to4 / native connection, you have to do a little more tweaking See ipv6-6to4.howto in the initscripts documentation (/usr/share/doc/initscripts-version/) for a brief primer on 6to4, which will get you up and going without having to sign up for a tunnel broker etc. I have two IPv6 tunnels running - one on a Fedora 10 server (qbert, served by my ISP here in Australia) and a CentOS VM (gyruss) through Hurricane Electric - both work OK [r...@qbert ~]# traceroute6 fedoraproject.org traceroute to fedoraproject.org (2610:28:200:1::fed0:1), 30 hops max, 80 byte packets 1 2001:44b8:61::62 (2001:44b8:61::62) 61.238 ms 63.470 ms 65.738 ms 2 vl67.cor1.adl6.internode.on.net (2001:44b8:8060:8000::1) 67.064 ms 69.794 ms 70.104 ms 3 gi0-0.bdr1.adl6.internode.on.net (2001:44b8:8060:14::1) 72.050 ms * * 4 pos4-2.bdr1.syd7.internode.on.net (2001:44b8:b070:2::1) 98.805 ms * * 5 pos1-3-0.bdr2.nrt1.internode.on.net (2001:44b8:f0a0:2::1) 217.948 ms 219.611 ms 221.365 ms 6 equinix-tyo.he.net (2001:de8:5::6939:1) 223.472 ms 197.651 ms 198.828 ms 7 2001:470:0:119::1 (2001:470:0:119::1) 310.388 ms 310.695 ms 309.959 ms 8 10gigabitethernet3-2.core1.pao1.he.net (2001:470:0:32::2) 286.479 ms 286.684 ms 283.265 ms 9 snvang.abilene.ucaid.edu (2001:504:d::bd) 318.081 ms 318.509 ms 318.226 ms 10 * * * 11 * * * 12 2001:468::155::2 (2001:468::155::2) 358.482 ms 358.215 ms 357.666 ms 13 2610:28:10e:2::1 (2610:28:10e:2::1) 393.498 ms 393.133 ms 392.833 ms 14 2610:28:105:13::2 (2610:28:105:13::2) 360.110 ms 360.089 ms 360.863 ms 15 2610:28:200:1::fed0:1 (2610:28:200:1::fed0:1) 361.113 ms !X 360.678 ms !X 361.396 ms !X [mflem...@gyruss ~]$ traceroute6 fedoraproject.org traceroute to fedoraproject.org (2610:28:200:1::fed0:1), 30 hops max, 40 byte packets 1 dotprofile-1.tunnel.tserv8.dal1.ipv6.he.net (2001:470:1f0e:16f::1) 8.000 ms 8.000 ms 8.000 ms 2 gige-g2-14.core1.dal1.he.net (2001:470:0:78::1) 8.000 ms 8.000 ms 8.000 ms 3 10gigabitethernet1-4.core1.chi1.he.net (2001:470:0:c4::1) 36.002 ms 36.002 ms 36.002 ms 4 ge-2-2-0.11.rtr.chic.net.internet2.edu (2001:504:0:4:0:1:1537:1) 56.003 ms 56.003 ms 56.003 ms 5 * * * 6 2001:468::155::2 (2001:468::155::2) 68.004 ms 60.003 ms 60.004 ms 7 (2610:28:10e:2::1) 64.004 ms 64.004 ms 64.004 ms 8 (2610:28:105:13::2) 64.004 ms 64.004 ms 64.004 ms 9 (2610:28:200:1::fed0:1) 68.004 ms !X 68.004 ms !X 68.004 ms !X Michael.
