When capturing the traffic with Wireshark there is no IPv6 traffic

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 folding@home can't connect.
When I disable IPv6 in the system the applet connects but Yum
behaves the same (multiple tries) and still folding@home can't
connect.

My name servers are set to opendns:

I have another machine, F11, behind the same ADSL router, Dlink DSL
500B, without problems.

Any ideas?

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

I think you misread his post, he doesn't *want* to do more tweaking to "get IPv6 working right," he wants IPv6 to go away. You seem to be telling him a really good way to do something he is desperately trying to avoid.

If you could change polarity on your expertise in helping people install and configure IPv6, you could probably tell him what surgery and chemotherapy will eradicate it from his system completely.
