I have do a fresh update of an OpenSuse to OpenSuSE 11.4. All works fine, except the update process.

It always resolve download.opensuse.org into the IPV6 address.

The result is the following:

zypper ref Download (curl) error for 'http://download.opensuse.org/update/11.4/repodata/repomd.xml': Error code: Connection failed Error message: Failed to connect to 2001:67c:2178:8::13: Network is unreachable

I have tryied also to put into hosts the entry like:

195.135.221.134 download.opensuse.org

but nothing, always resolv to ipvs. But the host command resolve it like this:

host download.opensuse.org download.opensuse.org has address 195.135.221.134 download.opensuse.org has IPv6 address 2001:67c:2178:8::13

Ipv6 is disabled:

cat /etc/modprobe.d/ipv6.conf #install ipv6 /bin/true

Urgent help needed, i am stuck....

I'm no networking expert, so only can say: 1-I recall no such problem accessing download.opensuse.org 2-my Grub kernel lines include this: ipv6.disable=1. -- "The wise are known for their understanding, and pleasant words are persuasive."

That does not disable IPV6.. you have to boot with parameter ipv6.disable=1 in grub ! Cheers. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Urgent help needed, i am stuck.... That does not disable IPV6.. you have to boot with parameter ipv6.disable=1 in grub ! Since a few days I have the same problem, so i fired up wireshark to see whats going on on network level.

Initially IP V6 was globally disabled with 'yast2 lan'. Doing 'zypper ref' (or libcurl) either timed out on some '::1' IP V6 address or more often just pretends "Repository xy is up to date" after 1 or 2 minutes. In any case I could not identify zypper related TCP connections with wireshark. Booting with kernel parameter ipv6.disable=1 did not help (and did not stop wireshark showing IP V6 packages traveling on my network).

look at /etc/sysctl.conf and uncomment the line where it says disable ipv6 then issue sysctl -p /etc/sysctl.conf This should sort it out Togan -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Well if you are running factory, the best place to get answers related to factory distro is factory-mailinglist. Since I am not using factory can't help you.

Are you sure ? that completely disables ipv6 at the kernel networking code level, there is no way you will be seeing ipv6 traffic from your host then... -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

you have 2 lines with "localhost" in /etc/hosts, translating it to 127.0.0.1 as well as to ::1. I'd suggest you remove "localhost" from the ::1 line, there should still be "ipv6-localhost" in that line. This kind of double-resolving "localhost" confuses a lot of software :-( Regards, Werner -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

With "ipv6.disable=1" on the grub command line. and you are running the command as "root" yes, as root. I did another reboot, nothing changes.

did you try with out the grub option because I can't seem to find a logic to understand why mine and Werner's method both fail unless it is not openSUSE :) Togan -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

My router has an IP V4 address, like all computers on my network (via DHCP4). Pinging download.opensuse.org shows the IP V4 address, as it should be, and browsing, e-mail, NTP works just fine.

Could this be https://bugzilla.novell.com/show_bug.cgi?id=684201 ?

Sven No, ipv6 nslookup for download.opensuse.org is successful, my problem is more https://bugzilla.redhat.com/show_bug.cgi?id=459756 which is cited in https://bugzilla.novell.com/show_bug.cgi?id=684534 comment #1 and https://bugzilla.novell.com/show_bug.cgi?id=685627 These make clear, why apps using libcurl are affected and not e.g. browsers) Looks like people updating to glibc-2.13 tend to be victim of no longer being able to update anything.
