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 [root@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:ffff:155::2 (2001:468:ffff: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 [mfleming@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:ffff:155::2 (2001:468:ffff: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. -- Michael Fleming <mfleming@xxxxxxxxxxxxxxxxxxx> - (EMail/XMPP/Jabber) WWW: http://www.thatfleminggent.com Fedora / Red Hat Packages: http://www.thatfleminggent.com/rpm-packages Twitter: http://twitter.com/thatfleminggent -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
