Disable ipv6 in solaris 11 express (2010.11)

Is there a way to disable ipv6 in Solaris 11 Express?
I can unlplumb inet6 interfaces but it created again after reboot.
# ifconfig v1 inet6 unplumb
# ifconfig lo0 inet6 unplumb
# ipadm show-if
IFNAME STATE CURRENT PERSISTENT
lo0 ok -m-v------4- ---
v1 ok bm--------4- -46
Is there a way to get that change persistent?
And what is there right way to get rid of ndpd daemon?
Whenever I disable svc:/network/routing/ndp:default it gets back online by 'routeadm -u' after reboot.

I know how to create addresses. I have no problem with ip4.
Addresses created and persistent across reboot.
The only problem that there is also bunch of ipv6 interfaces brought up at reboot and NDP daemon.
For now I found workaround:
1. make lo0 controlled by ipadm:
# ipadm delete-if lo0
# ipadm create-if lo0
# ipadm create-addr -T static -a 127.0.0.1/8 lo0/v4
2. Remove lines with "_family=26" from /etc/ipadm/ipadm.conf
3. reboot.
That's all I wanted.
# ipadm show-if
IFNAME STATE CURRENT PERSISTENT
lo0 ok -m-v------4- -4-
v1 ok bm--------4- -4-
# routeadm -u
# routeadm | grep ndp
disabled svc:/network/routing/ndp:default
If anyone know how to do the same without editing ipadm.conf please tell.

Disable IPv6 in Solaris 11

I work for a regulated bank in the UK and we do not use IPv6. IPv6 is disabled on all our switches.
Despite this control we have previously been told by external auditors that we must also disable IPv6 on our servers. No problem in Solaris 10 and lower.
Can anyone tell me a simple way to do this in Solaris 11? there doesn't seem to be a way to only plumb IPv4 interfaces.
I found an unreliable source on the internet telling me to hack the file /etc/ipadm/ipadm.conf but this means I need to reboot after plumbing interfaces, something that we haven't had to do for how many years? There must be a sensible way to do this...???

Do not under any circumstances unless directed by Oracle Support as part of fixing a bug modify the ipadm.conf file directly.
You can't disable IPv6 in Solaris 10 either, what you can do is not have any IPv6 addresses active on plumbed interfaces.
You can do the same in Solaris 11. However you can't disable the IPv6 loopback address on Solaris 11 if you have zones
and want to be able to do 'pkg update' using system repostitory from inside the zone.
To remove the IPv6 address on net0 do something like this:
# ipadm delete-addr net0/v6addr

Is it possible to use wi-fi networks without NWAM in Solaris 11 Express?

Hello,
I have disabled NWAM in Solaris 11 Express and now I'm trying to set up a wi-fi connection with dladm and ipadm only.
I reached a point where all seems well configured and I can even ping my on dhcp leased address.
But I can't ping the default gateway, for example.
I get something such as "Network unreachable".
This is in spite of "netstat -rn" shows a reasonable route.
Thanks in advance,
Carlos.

When I have it disabled I'm not being able to ping other addresses but my own.
I don't know if I'm doing something wrong or if nwam is doing something else under the hood when it's enabled.
Regards,
Carlos.

Deal-breakers for real use of Solaris 11 Express

I run Solaris 10 U9 for my home 12TB NAS box - based on Supermicro H8SSL-i2 motherboard (ServerWorks HT1000 Chipset and Dual-port Broadcom BCM5704C) and their 8-port SATA2 PCI-X card (AOC-SAT2-MV8). It's a great (but aging) platform and a rock solid OS with the unbeatable ZFS volume manager/filesystem.
However, despite my willingness to run Solaris 11 Express in this role, I can't because of these deal-breakers:
1) Lack of a full-featured installer that allows me to lay out or preserve existing partitions the way I want. Making /var a separate file system is a must. Ideally, I'd be able to run multiple versions of Solaris on the same box by customizing grub, and use my ZPOOLs on either Solaris 10 or 11 Express while I learn the new OS.
2) Lack of support for the Broadcom BCM5704C dual-port gigabit NIC (and others), which work wonderfully under Solaris 10, but are badly broken under Solaris 11 Express. I know I could disable the on-board Broadcom NICs and go buy an Intel card - but why the need for this? Won't there be a fix for Broadcom NICs?
3) Lack of support for modern, generic, server-class motherboards and PCI-e multi-port SATA/SAS cards. I wonder about the future for Solaris without support for modern, affordable x64 server hardware.
Maybe I'm missing the point and Solaris 11 Express is only intended to be run as a virtual machine under VBox or VMware. But it would sure be nice to be able to run it on my real hardware - even if it is just a small hobbyist rig. Any suggestions?
Regards,
Mike

In Solaris 11, you get a separate /var by default. If you update from Solaris 11 Express to Solaris 11, this transition doesn't happen automatically. If you decide to tackle it on your own, you need to be sure that it is done in a way that beadm, pkg, and other consumers of libbe will handle properly. I would recommend something along the lines of the following. This is untested and may break your system - prove it out somewhere unimportant first.
Do the work in a new boot environment so you reduce the likelihood that you will break things in an unrecoverable way.
# beadm create sepvar
# beadm mount sepvar /mntFigure out the name of the root dataset of the new boot environment, then create a var dataset as a child of that.
# rootds=$(zfs list -H -o name /mnt)
# zfs create -o mountpoint=/var -o canmount=noauto $rootds/varMount this new /var and migrate data
# mkdir /tmp/newvar
# zfs mount -o mountpoint=/tmp/newvar $rootds/var
# cd /mnt/var
# mv $(ls -A) /tmp/newvarUnmount, remount
# umount /tmp/newvar
# beadm unmount sepvar
# beadm mount sepvar /mntAt this point /mnt/var should be a separate dataset than /mnt. The contents of /mnt/var should look just like the contents of /var, aside from transient data that has changed while you were doing this. Assuming that is the case, you should be ready to activate and boot the new boot environment.
# beadm activate sepvar
# beadm unmount sepvar
# init 6

How can I disable IPv6 EUI randomization with group policy?

I need to turn off IPv6 EUI address randomization. It can be done in netsh (a few commands) or powershell (Set-NetIPv6Protocol -RandomizeIdentifiers Disabled). How can I do this in group policy without scripting?

Hi Jordan,
Before going further, I hope that the suggestion provided by Martin can be helpful.
It seems that we can't configure this setting via native policy.To configure IPv6 settings,
we need to download ADMX files for IPv6. However, per the following article, the IPv6 settings that can be configured are:
Enable all IPv6 components
(Windows default)
Disable all IPv6
components (the setting you probably want)
Disable 6to4
Disable ISATAP
Disable Teredo
Disable Teredo and 6to4
Disable all tunnel
interfaces
Disable all LAN and PPP
interfaces
Disable all LAN, PPP and tunnel
interfaces
Prefer IPv4 over IPv6

How can i disable ipv6 in OL7?

Hi everybody,
how can i disable ipv6 on my OL7 box?
In /etc/sysctl.d i have test it with the file: ipv6.conf:
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.<interface>.disable_ipv6 = 1
But this doesnt work.
Does anybody know how can i disable IPv6 in Oracle Linux 7?

What I would recommend is not to set implicit or redundant parameters:
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
There is no need to disable the "default" interface, since it is already included in the "all" statement.
I do not know, but there could be a possibility that such statements disable the network card in question, but in turn enable every other. In such case, your 2nd statement invalidates the first. Perhaps that was was part of the problem when using your other configuration.

Will Disabling IPv6 harm a Windows 8 or Server 2012 R2?

I have a script that was written for Windows 7 and server 2008. I would like to know if it was harm a Windows 8 or any build of Server 2012 box. If so, could you please list what it would harm.
It was create to help with speed issues for an older network based program.

Hi:
I don't think anyone can say for sure if it would cause any harm to any build of Windows 8 or Server 2012Rx. No one would have tested disabling IPV6 on all the possible combinations. The conventional wisdom is to NOT disable IPV6, but given special
circumstances I suppose it might be done:
http://blogs.technet.com/b/sbs/archive/2008/10/24/issues-after-disabling-ipv6-on-your-nic-on-sbs-2008.aspx
While written for Server 2008 and SBS 2008, you might want to check the above link for ideas. About half way down it discusses some considerations.
Are you still running some older program that might benefit from this? If so, have you actually tested it without disabling IPV6 on say one server and one station. It would be easy enough to test then reverse the changes if there was no perceived
benefit.

Is it possible to disable the optimized compiler in LabVIEW 2010

Hello,
I have a project that take 3 minutes in LabVIEW 8.6 to build and now with LabVIEW 2010 it take 10.5 minutes. 3x more longer.
In fact my project as 61 .lvproj for a total of 4300 vi's that take 1 hour to build. If I interpolate, the entire build process will take 3 hours in LabVIEW 2010. This is not acceptable
I know that the new compiler optimize the code for better performance, but if I don't need better performance.
Is it possible to disable the optimized compiler in LabVIEW 2010 with an INI key in LabVIEW.ini.

One Application Builder setting you might try out to make builds go much more quickly is the Remove Unused Members of Project Libraries checkbox and the Modify Project Library File after Removi....
This can drastically cut down the build times. Note, however, that this option does not work well if your application will load external plug-in VIs when it runs, because the libraries of those plug-in VIs may conflict with the modified libraries in the executable file. If you don't have a plug-in architecture, this will not affect you.
The "Remove unused members of project libraries" was already selected but not the "Modify project library file after removing unused members" and selecting this cut the build time from 10.5 min to 4 min.
Thank you Jarrod for this tips

HT4667 How to disable IPv6 on MAC OS X Lion?

Hi everyone,
I am using Macbook Air OS X Lion. I have been facing slow internet browsing problem from quite a while now. I checked the forums and found that lot of people are facing the same problem. Also found that disabling IPv6 or setting it to manual mode will help fixing the issue. But another big challenge is how to do it. I tried setting it to manual which would need router address, IPv6 address and prefix length which is supposed to be collected from your ISP. Unfortunately Comcast hasnt implemented IPv6 yet so couldnt find that information. Also couldnt find the disable option as mentioned in one of the Apple article.
So I am stuck with Macbook air with slow internet speed. If anybody could help, it would be much apprecaited.
Thanks,
SJ

Solaris 10 express developer ed. dvd checksum error

Hi,
I downloaded the solaris 10 express developer ed. dvd. I used Sun Download manager for the download. the file e had checksum error. Hence the DVD contains checksum error. Is there any way we could correct the download without the need re-download the entire file. Other files ending a,b,c,e dont have this problem. Am i the only one getting this problem or is it a known issue?

Sorry there is no real way to solve this other than downloading the last segment of the file.

EA3500 Smart Wi Fi - How to disable IPV6 to address Parental Control Issue

Hi
I've been reading that parental controls does not work with IPV6.
I would like to disable IPV6.
How would I do that?
P.S.: I noticed responses for EA4500 that there is a check box to disable the IPV6. Very straight forward but my interface
does not have the same layout of the GUI.
Thanks

Hi petroski1, the process of disabling IPv6 in your router depends if you’re using the Classic user interface or the Linksys Smart Wi-Fi. You may refer to this link, for instructions: http://kb.linksys.com/Linksys/ukp.aspx?pid=80&app=vw&vw=1&login=1&json=1&docid=bd520bcb07a6474596169...
If you’re using the Classic one, select IPv6 under the Setup tab and just disable it. And if you’re also using the Linksys Smart WI-Fi, go to Connectivity, select Internet settings, click on IPv6 click edit and make sure to uncheck the enable box.

Using Solaris 11 Express for a multiprocessor CAD/CAM x86-64 system.

I'm considering using Solaris 11 Express as the OS for a multiprocessor Computer Aided Design/Computer Aided Manufacturing custom built x86-64 system for my machine shop business. I would like clarification of the license in this situation.
Would I be allowed to use Solaris 11 for free under the open-source license, or would I have to purchase a commercial license? Would I have to pay for program updates? Does just the Oracle Solaris Premier Subscription for Solaris 11 require payment rather than the actual software as well? Would I be required to purchase an Oracle Solaris Premier Subscription to use Solaris 11 in my situation, or can I purchase the Oracle Solaris Premier Subscription at a later date.
I have a lot of respect the open-source concept, and I would only use Solaris while keeping it's license intact. So the answers to these questions are very important factors affecting my decision regarding whether or not my company will start to use Solaris.

I'm afraid you'll have to contact Oracle directly to clarify what applies in your situation.
