I’ve had a hell of a time with this and now all but YAST2 are ok. Going back some time to 10.0 this could be used to disable it very completely.
open terminal and run
echo “alias net-pf-10 off” >> /etc/modprobe.conf
echo “alias ipv6 off” >> /etc/modprobe.conf
restart computer.
Has anyone used this on more recent issues even 11.4 and are there any repercussions?
I assume that the inverse will but it back on ie off’s just become on’s?
I will be using cups when I install my printer which is one concern and I am not at all sure that modprobe will do anything anymore?
I also recollect that there is a command to cause the kernel to effectively reboot which would save restarting. Can’t remember what it is. Maybe some one can refresh my memory.
forget that…‘they’ rolled IPv6 into the kernel with 11.2 (or .3, or .1
i don’t really remember)…
so if yours has it in the kernel, you need to add this to the boot
options in grub’s menu.lst
ipv6.disable=1
and, many indivudual net apps carry internal IPv6 code…firefox for
sure is usually in need of redirection…but you said “in general”, so i
cease…
sorry, i too am drawing a blank on the magic to tell the kernel to pay
attention, without booting…

So I have been having a hell of a time recently getting to the openSUSE forums. I can’t place it to anything in particular except the issue is affecting two computers running different versions of openSUSE. All of a sudden, I could not get to the openSUSE forums reliably and the issue was DNS related. I switched to using the openDNS servers, but it was hard to tell if this was really helping or not. So, I have went the disable ivp6 in the kernel and rebooted. It is too early to tell if this is the problem or not, but for now one computer seems OK. Why all of a sudden would access to the openSUSE forums stop working properly if ivp6 is enabled? Can anyone hazard a guess?

did you also shut off IPv6 in your firefox?

Yes, I could get to the forum by IP, but it only made the first page work as the rest would still fail when DNS is not working. I continue to have an issues, even since our last message. It works to the forum and then it does not. I have disabled ipv6 in Firefox & Kernel. Removed the openDNS in my router, going back to the default for Time Warner. Nothing seems to fix the intermittent DNS ability to find the openSUSE forums from my home.

I also use Time Warner as my ISP. Mine is in Kansas City. With it, I run
full-blown IPv6 as it comes out of the box. I don’t have any IPv6 non-local
addresses, but nothing gets in the way. On the other hand, I did get fed up with
the delays that came from Road Runner’s DNS servers, and changed
/etc/resolv.conf to use Google’s public servers with addresses 8.8.8.8 and 8.8.4.4.

Thanks Larry for the information. I will give them a try. I just have no idea what is wrong, but a better DNS server might be the answer.
I found the following listing for DNS servers including Google and Level 3. I happen to know that Level 3 has a server farm close by my location as I did work on their HVAC control system, so I am giving theirs a try to see what it does.

I have had IPv6 enabled since they started doing it years ago without any
problems, except that my ISP only uses IPv4. In my lan v6 works. If it
doesn’t work for you, the issue is not Linux. I can’s say what it is, but
not Linux.

please be a little more careful with how you quote (or don’t), because
the way you did the above makes it look like i said what you actually said…
(which is ok, this time because i agree it is not a linux
problem–well i can also say it is a problem induced by many DNS operators)

I forgot we are on a forum and people might not see the missing quote marks
and interpret the text incorrectly. Which might happen again now and think
that “I” said the above >:-)

Had lots of problems importing my emails but finally did it with mandriva then over installed suse 11.4, fresh but leaving the desktop alone. It looks like it’s still using ipv6 even after disabling it in the network configuration.
Then did an update - IPV6 control isn’t available in Firefox now.
IPV6 performance varies with isp. Mine is so so but very slow in real terms. Some are less lucky - it doesn’t work at all. I’m currently using googles dns servers but that’s not a good idea speed wise from the UK.
I also bunged my old discs back in and installed 10.3. That’s what I have been using up to now. YAST offered to disable IPV6 during install. I just can’t understand why that facility has been dropped.
Open yast;
Click “Network devices”.
Click “Network Settings”
Click on the “Global options” tab.
Unselect “Enable IPv6”
Click OK, then follow the prompts to complete the changes. It will tell you that you have to reboot before they become effective.
lol! It has been noticed with thanks. I have a bee in my bonnet I suppose. The kernel seems to be set up to accept either in standard form. Some apps have the ability to choose and that to me is the sensible option. I have since moved on to my graphics card and used the google dns as a quick fix. The card problems are now much much worse. The other aspect of that fix was possible problems with cups. No idea just wonder.
I have my doubts about the yast global option also mentioned earlier and didn’t find it when I looked which seems odd but who knows. I did find a conf file with a disable ipv6 completely setting so I changed that. Konqueror then work but yast was still the same. Could be that it notes something somewhere else when global options are used but I failed to notice it in a machine wide search for contains IPV6. :sarcastic: There is a kernel compile option though. This is interesting as it suggests that there might be a boot and install parameter (cheatcode etc) that disables it. I spent some time looking for a list of these and didn’t really find anything conclusive.

you recognize, i hope, that SUSE and openSUSE has been “IPv6 ready” for
a long long time…unfortunately there are still lots of servers out on
the net which are misconfigured (on just not configured) for IPv6, and
turning off IPv6 in openSUSE is just a means to avoid the silliness that
gets fed back (and S L O W S down) connections to IPv4 sites (which
still are predominate)…
with IPv6 killed in openSUSE you will be unable to nav to IPv6 sites,
but you will get to IPv4 sites quicker (than having to wait for IPv6
queries to time out)…
you can check how your system (keyboard to distant destination) is doing
by trying to connect to these IPv6 test sites:
IPV6 control isn’t available in Firefox now.
