Re: [opensuse] opensuse 12.3 x64 and could not activate IPv6
Hi, we've disabled ipv6 on all servers, we hadn't IPv6 IP from providers. In this case the server is a firewall between LAN, DMZ and WAN. I enabled IPv6 on anothers server too, but only on this " important" server I've problem to enable IPv6. Why ? I've 6to4 tunneling at home on opensuse 12.2, at work is native IPv6 on another opensuse 12.2 with dns service, no problem at all... Kernel isn't old - "Linux kost.fnhk.cz 3.7.10-1.40-default #1 SMP Thu Jul 10 11:22:12 UTC 2014 (9b06319) x86_64 x86_64 x86_64 GNU/Linux". J.Karliak Dne 17.9.2014 v 08:29 Per Jessen napsal(a):

Good morning, I've some weird problems with opensuse 12.3 x64-bit on HP DL380G7 server, in the yast I've checked "enable ipv6" and rebooted server. Still I've not enabled IPv6, "sysctl -a" shows me only ipv4 configs. Did I missed something somewhere ? On another servers all works fine. This server has all updates (from tomorrow). Thanks and best regards J.Karliak.
Hi Josef
it would have been better to start a new thread instead of tagging this on to the "DNS not working 1.31" thread -
however, there isn't really enough information for anyone to go on. Why did you need to enable ipv6 on this server, was it disabled before? I have a number of servers running 12.3 with ipv6, both physical and virtual, no problems.

I am not familiar with how to disable/enable IPv6 at all, but I thought there was a kernel command line argument too?

I've enabled all IPv6 by the Yast2 -> Lan -> "Enable IPv6" and rebooted. Except this firewall all was after reboot ready to set IPv6, huh ...
So, we have to run with IPv6 over older firewall (SLES11SP3) , it is fully functional... But as I said, it is old server, HP DL380G4. Thanks and best regards J.Karliak. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Okay, that looks good - was it also loaded: cat /proc/sys/net/ipv6/conf/all/disable_ipv6

How do you know that IPv6 remains disabled? I mean, what indicators are you looking at?

The server age is not really relevant, except for maintenance etc. -- Per Jessen, Zürich (18.2°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
Hi, problem is, that IPv6 isn't loaded, in /proc there is no ipv6 subprocess. Here is a proof :) : $cat /proc/sys/net/ipv6/conf/all/disable_ipv6 cat: /proc/sys/net/ipv6/conf/all/disable_ipv6: No such file or directory and if I "ip add show", there is no IPv6 IP, including IPv6 link address. Damned no IPv6 process at all :-/ There should be some thing maybe - Iv'e distroupdated to opensuse 12.3 from opensuse 12.2. IPv6 was disabled as my default installation changes. Should opensuse while distroupdating detect settings and disable it by some ??????? completly ? I don't think so, but now I'm out of the ideas . J.Karliak. Dne 17.9.2014 v 12:01 Per Jessen napsal(a):

Okay. Check if module "ipv6" is loaded. If not, check your modules config - /etc/modules.conf etc. -- Per Jessen, Zürich (20.5°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Just wondering, was I right about the above? -- Per Jessen, Zürich (16.7°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

That can't be... systemd loads the ipv6 module in an explicit fashion at early boot UNLESS the user has blacklisted the module or it is disabled in the kernel command line. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Yes, that's exactly what I suspect has been done. -- Per Jessen, Zürich (18.0°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
