Does the Linux kernel IPv6 NAT ?
I know linux kernel was not supposed to support IPv6 NAT.
But I am curious know , is there any Linux kernel which supports IPv6 NAT.
There is no verb in your question, so I don't know what do you ask about.
There are multiple guides on the net on how to setup ipv6 NAT on linux. This question shows you did no research on your own. Please read how-to-ask.
Does the linux kernel support the IPv6 NAT?
Yes it does. Have you even checked google ?
I know linux kernel was not supposed to support IPv6 NAT.
No, this statement is wrong. Linux kernel is supposed to support IPv6 network address translation.
Is there any Linux kernel which support Ipv6 NAT?
Any linux kernel with version greater then 3.9.0 and iptables utility greater then 1.4.18 supports ipv6 NAT (from here). So there are plenty linux kernels with that support.

I have a Mac OS X server running one instance of Windows 7 x64 Pro. The network adapter is in bridge mode, my router is assigning the proper IP address according to the mac of the VM through the DHCP configuration but I cannot ping the ip of the virtual machine even from the Host OS...
Any idea on shat is the problem? Is this Mac OS X Server related?
I had a similar problem with XP. Turned out that the windows (guest) firewall was blocking the pings.
Turning off the firewall (briefly) allowed the ping to work.
I don't know if what I want to achieve is actually feasible or not. I have an RTL8192CE wireless network Mini PCI card, which definitely doesn't work properly on Linux (running Ubuntu 12.04 64-bit (Precise Pangolin)). I have already tried everything I could think of: I downloaded the latest drivers from the Realtek homepage, tried using NDISwrapper with several different sets of Windows drivers, and also tried using generic wireless backports, etc. None of it solved my problem.
It does, on the other hand, work perfectly on Windows... I dual-boot Windows 7 and Ubuntu 12.04, both 64-bit. Apparently, there is a bug in Ubuntu related to this card.
I want to know whether there is a way to use a virtualized Windows installation (Windows XP or Windows 7, preferably not Windows Vista) under my Ubuntu 12.04 64-bit that uses a native Windows driver (since the network card works perfectly in Windows). The virtualization software can be either VirtualBox (prefered), VMware or any other. There isn't any problem if I have to manually configure that by shell scripting or anything similar.
So, to make it clearer, I have a VirtualBox installed in my Ubuntu 12.04 (my host), which I use to run Windows 7 (my guest). I wanted to know whether this virtualized (guest) Windows 7 could have "direct" access to my wireless interface -- such as the dual-booted Windows 7 I have installed, without passing through the Ubuntu drivers.
Apparently I could not achieve that by using VirtualBox's guest additions, could I?
PS: I believe none of VirtualBox's networking modes (NAT, bridged networking, internal networking and host-only networking) would allow me to do that, am I correct? How could I solve that problem?
What you are asking for is called PCI Passthrough in VirtualBox - and it should be considered a very advanced topic. I have experimented with this feature before in VirtualBox and VMWare ESXi (make that vSphere...) and it can be extremely fragile.
I would suggest you spend some time reading the VirtualBox manual section on this (Chapter 9: Advanced Topics), there are some limitations you will want to be aware of as well as just know that this is an area of virtualization that is very young and immature. Off hand, here are some of the rather strict requirements before you can even begin:
Your hardware must have an IOMMU (Intel calls it VT-d, AMD -> AMD-Vi)
Your guest must be configured with hardware assist enabled (VT-x or AMD-V)
Your host Linux kernel must be built to utilize the IOMMU hardware
If your hardware/software meets those rather strict guidelines, give it a shot. What will happen is your guest will be effectively given direct access to your wireless PCI card and it will show up directly as a PCI device to your guest. You will install and use the drivers exactly as you would if Windows were your host operating system instead of your guest.

I would like to connect to QNX Neutrino OS (qconn) running on the VirtualBox from the Momentics IDE running on the Windows 7 (the same computer) via IP on 8000 port. I tried to get IP address of this virtual machine, and it seems to be the same as my real machine's and it doesn't work on it. Thank you in advance for your help.
So, just to clarify:
You are using Windows 7 as your host OS
QNX Neutrino RTOS is running in a VM
Using Momentics on the Windows host, you want to connect in the IDE to the QNX target
Let's assume the IP address of your Windows 7 machine is 192.168.1.101 (acquired by going Start ==> Run... ==> cmd ==> ipconfig )
First, have the network type for your QNX OS VM set to NAT (Network Address Translation). Then, you need to setup port forwarding (please see this URL: http://www.rustyrazorblade.com/2010/12/virtualbox-4-nat-port-forwarding-gui/).
Once you've finished, you should be able to connect from the Momentics IDE in Windows 7 to the QNX VM by specifying the following QCONN target in Momentics:
Target: 127.0.0.1:8000
HOSTNAME: QNX_NTO
The forwarding you setup will cause all connections to 127.0.0.1:8000 (the Windows host loopback connection) on port 8000 to be automatically redirected to your QNX VM.
I've done this myself and it worked. Hope this helps for you.
Cheers!
If possible, configure your QNX guest virtual machine to use Host-Only Networking - this will put it on a private network segment with your host Windows 7. You should then be able to access it by the IP address is it assigned. By default your Win7 host will have an address of 192.168.56.1 and your virtual machine will likely be assigned 192.168.56.2.
If your guest requires access to the internet or other networks, you could experiment with other network options like Bridged (the virtual machine would appear as another computer on your same network) or NAT (you would need to add port forwarding options).
Hey all,
I was wondering how does clipboard-sharing work when using a hosted virtualized OS.
I mean, how would I go about writing such a bridge, for say a Windows host running a Linux guest?
In my experience, this only works when the "guest drivers / additions" are installed which enabled the host to communicate with the guest. I guess it's possible for the host to peek into guest memory and get the clipboard but that'd probably be much, much harder than a guest driver.
If you're not using a virtualization package that offers an SDK I think you'll be in for quite a task hacking from host to guest to peek into memory and processes.
I need to access my http://localhost/ (in IIS 6 on VM) from the MAC Host (Safari).
I am using NAT (or can use Bridged) network connection to the Guest, but not sure how to identify IP addresses, etc. A novice when it comes to networking ;-)
Thanks,
Geoff
A simple solution if you want a consistent hostname is to install Bonjour for Windows in the VM with bridged networking and then use http://computername.local in Safari.
It's possible to forward ports from a NATed VM too or ensure a consistent IP address if you want; some instructions are here.
In Safari, you should be able to type in the IP address of your VM and be able to access IIS that way. Firewall settings permitting of course, but I assume you've set that up already.
If it doesn't work, could you please post more details about your current setup (VM software being used to run the guest, OS X version, Windows version) and I'm sure we'll be able to troubleshoot further.
Just try to off Windows firewall on your virtual machine. This works for me in NAT mode.
Also, as mantioned before, is nice to have Bonjour for Windows installed to have more useful URL.
