IPv6 plus IPv4 on Solaris 8/9

Can IPv6 and IPv4 be enabled together on Solaris 8 or Solaris 9? If so can they be used inter changably in any fashion?
Does introduction of IPv6 change any network cards?
If a machine is enabled with IPv6 alone, then how will it interact with machines supporting IPv4?
Thanks a lot in anticipation of your answers.

Yes you can run the protocols together. They run on the same net card at the same time.
They are not "interchangeable" as you put it. IPv6 is not compatible with IPv4 in the sense that a pure IPv6 host cannot communicate with a pure IPv4 host, which answers another of your questions I think.
If you have a pure IPv4 box A and a pure IPv6 box B you need a gateway C that runs both protocols and can route between them.
And yes, your network card is "changed", in that it now passes IPv4 and IPv6 packets up to the kernel.

Convert from IPv6 to IPv4

Hi,
when using: request.getRemoteAddr() I get the ip in IPv6 format.
But, I am using maxmind to get geo information, which needs ip in IPv4 format.
How can I convert from IPv6 to IPv4?
Thanks.

I'm not too familiar with IP6, but I think it is controlled by the OS and hardware. Windows Vista, for example, uses ip6 by default, so you would need to switch to ip4 in order to get request.getRemoteAddr() to display as ip4 (such as it does running on my MacBook Pro)
If you are trying to get ip4 for all clients that connect and you don't know their OS, you can try some third party freeware programs out there like IPConvert.

IPv6 in IPv4 Tunneling

Any support for IPv6-in-IPv4 tunneling, e.g. HE, for us whose ISP do not do native IPv6 or 6RD?

All of the Linksys devices currently support only Internet Protocol version 4 (IPv4) addressing. However, WRT610N and E4200 nominally support the latest Internet Protocol version 6 (IPv6) but these products are NOT yet IPv6 compliant.
NOTE: Future firmware releases of Linksys devices will be available to support IPv6.
This information is OUTDATED.

Filtering/Dropping IPv6 on IPv4-only Devices?

Hi All -
Got an interesting requirement that (for something seemingly simple) has been remarkably challenging to locate a solution for...
Having a problem with random IPv6 traffic showing up on the enterprise LAN from time to time and freaking out certain network-connected devices that don't know how to process it (CPU 100%, etc.). So I'm looking for a way to filter/drop that IPv6 traffic at the network edge. I can certainly set the core 6500's not route (or even ignore) IPv6, but that still doesn't stop it from running around WITHIN a VLAN.
Is there a way that a IPv4-only device can identify IPv6 traffic (by a protocol type code or something along that line) so that it can be filtered/dropped before it even makes it onto the backbone?
Thanks in advance!
Mike

Mike-
Good question! The first thing I thought of was VACL's, but VACLs w/IPv6 are not supported on the 6000 series switch.
http://www.cisco.com/en/US/tech/tk389/tk814/technologies_configuration_example09186a00808122ac.shtml#vacl
Are the 6500's your access layer? Are they your L3 gateway? Is it possible for you to find the device(s) running IPv6 and correct them?

Why can't Safari 5.1 prefer ipv6 vs ipv4?

So prior to the installation of Lion, I had configured my network for ipv6 connectivity to the internet via Hurricane Electric Tunnel broker. Simply put, it was amazing. Now after the installation i've realized that my ipv6 support has slowed dramatically. When I tested to see exactly why this took place, i recieved the following:
It preferred ipv6 pre-lion, now its hot for ipv4, what gives? So I tested Dual Stack connectivity and i got this:
When i chose the ipV6 only test, I got this:
There's a not below the results that state: "If your browser is able to connect to the IPv6-only Test, yet using the Dual-Stack Test returns a page with a red box stating that you are using IPv4, then your browser and/or IP stack in your machine are preferring IPv4 over IPv6, which is undesired/broken behavior."
Since its obviously a Safari issue, Any idea how to correct this?

This may be a bit premature, as iPv6 has not been fully implemented yet:
What is IPv6?

http://en.wikipedia.org/wiki/Ipv6
The last five blocks of the IP Version 4 addresses have been handed over to the regional bodies that distribute them.
Those five blocks, called /8s and which contain 16 million addresses each, are expected to be completely depleted by September 2011.
The move to the new addressing scheme, IP version 6, is under way but could take years to complete.
"This is one of the most important days in the internet's history," said Rod Beckstrom, head of net overseer Icann at a press conference called to mark the handing over of the final five blocks.
"It is a point that the founders of the internet thought would occur far in the future," he said. "It gives us an opportunity to shift to an internet protocol that offers a pool so large that it is difficult even to imagine."
IPv6 has a pool of addresses a billion, trillion times larger than the 4.3 billion that IPv4 can support.
While that pool of 4.3 billion addresses was seen as plenty when the net was getting going, its recent growth has seen it get used up very quickly.
The shift to IPv6 was needed, he said, to support the continuing growth of the net and its greater use by all kinds of connected devices.
"The future of the internet and the innovation it fosters lies with IPv6," said Mr Beckstrom.
Despite the imminent exhaustion of the IPv4 pool, few ISPs, companies, academic organisations and others have made the switch. A World IPv6 Day is being planned for 8 June that will give governments, companies and others the chance to test out the technology.
Cisco, Verizon, Yahoo, Google, Facebook and many others have committed to testing IPv6 on 8 June.
In the UK, the switch to the new addressing scheme might take years, said Philip Sheldrake, head of 6UK, an organisation set up to advise companies how to make the move.
Most firms would upgrade equipment, routers, hubs and modems, as part of their "normal replenishment cycle", he said.
Equipment that is going to be in use for years before being replaced could be fitted with "dual stack" systems that can handle both IPv4 and IPv6 addresses
Some ISPs and others may take a more aggressive approach to the switch, said Mr Sheldrake.
"There are automated approaches that involve some remote updating of firmware in equipment," he said.
"The internet does not break when IPv4 is exhausted," said Mr Sheldrake explaining why this long term shift was feasible.
"What we are looking at here is that some parts of the world that have less IPv4 will be more on the front foot of adopting v6 than the UK because we have some good v4 space," he said.

OpenVPN IPv6 client, IPv4 server, Port forwarding?

I'd like to use an anonymous VPN with OpenVPN, but my new ISP only gives IPv6 addresses and IPv4 only via DualStack lite (4in6).
As a consequence, my machine is only reachable with IPv6 Port Forwarding.
The VPN-Provider only supports IPv4.
Now the question:
Can I reach my machine through IPv6 Port forwarding with OpenVPN and get a static IPv4 and Port forwarding(v4) from him?
As I see it:
I should be able to establish a connection with the VPN. I get a static address and the provider is forwarding the ports. Because I made the connection TO him it doesn't matter which ports are open on my side. Right?
Or is it the other way around, that both need ports that can be forwarded?

I guess you mean forwarding from WAN (server) to LAN (client) (both static IPs)?
(Server must be your Internet gw/router.)
NAT requires the ipfw firewall running so you need to add these ports (TCP? and/or UDP?) to the "allowed in" list for the server public/WAN IP. Turn on logging of denied packets to see what happens.

IPV6 and IPV4 ACLs

As we begin deployment IPV6 we are going to be in a mixed IPV4/6 environment - we have required access lists implemented for IPV4 and must applty the same ACL defined for for IPV6. Is it possible to apply IPV4 and IPV6 access lists concurrently on an interface or is a single access list containing both IPV4 and IPV6 addresses called for?

You will need to have concurrent ACLs applied to an interface.
The access lists are address familiy specific in their syntax and features so they cannot be mixed. An indicative example is shown below.
interface Ethernet1/1
ip access-group test-v4 in
ipv6 traffic-filter test-v6 in
ip access-list extended test-v4
permit ip any host 1.1.1.1
deny ip any any
ipv6 access-list test-v6
permit ipv6 any host 2001:DB8::1
deny ipv6 any any

Sun Video Plus PCI on Solaris 9?

Hi!
I have a Blade 100 here, with Solaris 9 installed. I have a firewire camera attached, no problem, it works great with Sun Forum.
However, I want to use the machine to import analog videos into mpg. We have a Sun Video PCI installed, and I have a CD with the software for this, Sun Video Plus version 1.3. In fact, I only need something capturing audio an dvideo and writing it in mpg-format to disk. This software is for Solaris 5, 6 and 7...
I heard in some newsgroups, that it is possible to use the software with later versions of Solaris. But I never found some real documentation or Howto on this topic. Do I have to install just the unVideoPlus-Software, as the drivers and the xil come with Solaris 9 (I see a 1.4-version in admintool) ? And do I have to set any environment variables, or is this done by the package installation? If yes, wher (in which files) does it set these variables?
And, last not least, is there any free software to simply capture from video and audio input? As the bundled software just supports very asic formats, I wonder if I shouldn't use software for compression, e.g. ffmpeg, but I still need something like a dv-file ;-)
Thank You, CU, Lars.

Any IPv6 support prior to Solaris 8?

Greetings! Can anybody confirm whether or not IPv6 is supported prior to Solaris 8? I suspect not, but maybe I am missing something. If so, does anyone know the patch/package number(s) for installing IPv6 on Solaris 7 (and/or Solaris 6)? Thank you kindly.

IPv6 was first introduced in Solaris 8. Not available prior to that, from Sun. Who knows "what's out there?"

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

How to configure DNS to support ipv4 and ipv6

I have a 2008 r2 domain controller in my lab.
i'm doing Exchange 2007, 2010 and 2013. I have mix Windows 2008 r2 servers for other applications.
i'm running into issues where i'm thinking it is time to have both IPV4 & IPV6 to run on all lab machines.
I can't get a clear picture on how to accomplish a mix environment. in the DNS administrator do I create a new "reverze lookup zone" with only the IPV6? or do I have to create a new record in the "forward lookup zone" to with both IPV4
& IPV6 which the later points to the new "reverse lookup zone".
I see a lot of internet article but little on "how to".
or on the DC should I enable the DHCP role to support the IPV6?

1. You assign an IPv6 address to the domain controller/DNS server
One method is letting this site (legitimate) create a random private IPv6 range for you:
http://www.simpledns.com/private-ipv6.aspx
For example:
fd06:fcde:8b4e:d6bd:xxxx:xxxx:xxxx:xxxx
You can configure the x's like this (you cannot leave the x's there):
fd06:fcde:8b4e:d6bd:0000:0000:0000:0001
If you close and open IPv6 properties, or do an "ipconfig /all" you'll see that the IPv6 is abbreviated as follows:
fd06:fcde:8b4e:d6bd::1
That's normal.
If you look in your forward lookup zone, you'll now see this IPv6 address (you may have to register that manually - ipconfig /registerdns - but it seemed to happen automatically for me.
So there is no need to create a separate forward lookup zone for IPv6.
OK, but what about the reverse zone?
2. Create reverse lookup
In DNS Manager (what you call administrator), right-click on reverse lookup zone, select New Zone, click, Next, Next (default values are fine) until you choose between IPv6 and IPv4. Selecft IPv6 of course.
Then enter your prefix as shown here:
That's it. The reverse lookup information is configured automatically (your prefix " backwards").
Now, unlike with the forward lookup zone, my domain controller does not seem to be registering its name in the reverse IPv6 zone: there's only the SOA and NS record.
But that's another question.
Please mark as helpful if you find my contribution useful or as an answer if it does answer your question. That will encourage me - and others - to take time out to help you.
