Vista Not Playing Well With IPv6

netbuzz writes in to note that some early adopters of Microsoft Vista are reporting problems with Vista's implementation of IPv6. An example:"'We are seeing a number of applications that are IP-based that do not like the addressing scheme of IPv6,' says one user. 'We will send a print job to an IP-based printer, and the print job becomes corrupted. We're seeing this with Window's Vista machines. When IPv6 is installed, this happens without fail. As soon as we remove IPv6, all of our printer functions return to normal.'"

MS' Teredo (IPv6) blog

MS has a blog for this sort of thing. Sean Siler promised to answer questions and provide help on issues pertaining to this via an email list I'm on. http://blogs.technet.com/ipv6/ ... Anyhow, those parties with IPv6 issues, I bet ya a HUGE portion of them are using NAT...

They need a better implementation

I think they should scoop the one out of BSD UNIX.

Hell, it worked for them pretty good LAST time..

The entire IP stack of Vista/Longhorn has been reimplemented. IPv6 is kind of an "add-on" to the networking code in XP, but in Vista, IPv4 and IPv6 are implemented in a unified stack.

Just sayin', the behavior is going to be different, and having some bugs to shake out is really no surprise.

IPv6 FAQ

Q. How do I disable IPv6 in Windows Vista and Windows Server 2008?

A. Unlike Windows XP and Windows Server 2003, IPv6 in Windows Vista and Windows Server 2008 cannot be uninstalled. However, you can disable IPv6 in Windows Vista and Windows Server 2008 by doing one of the following:

- In the Network Connections folder, obtain properties on all of your connections and adapters and clear the check box next to the Internet Protocol version 6 (TCP/IPv6) component in the list under This connection uses the following items.

This method disables IPv6 on your LAN interfaces and connections, but does not disable IPv6 on tunnel interfaces or the IPv6 loopback interface.

- Add the following registry value (DWORD type) set to 0xFF:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip6\Parameters\DisabledComponents

This method disables IPv6 on all your LAN interfaces, connections, and tunnel interfaces but does not disable the IPv6 loopback interface. You must restart the computer for this registry value to take effect.

For additional information about the DisabledComponents registry value, see Configuring IPv6 with Windows Vista.

If you disable IPv6, you will not be able to use Windows Meeting Space or any application that relies on the Windows Peer-to-Peer Networking platform or the Teredo transition technology.

Heh... Removing (proper) IPv6 on Linux requires kernel re-compile and if you try on Ubuntu to remove something like Avahi (which 99%+ of people do not need and which _can_ cause a lot of problems with DNS) then you'll see that it would "remove" almost the whole of your system through dependencies.

Or, if you're not an idiot, you just add "blacklist ipv6" to /etc/modprobe.d/blacklist.

Umm, yes! On linux its as easy as:
rm /lib/modules/'uname -a'/kernel/build/somemodule.ko ; depmod -a on Mac OS X its
rm -r /System/Library/Extensions/YourKext.kext; rm /System/Library/Extensions.*; See?

Vista Performance Tip

[The MAZZTer]

If you have IPv6 enabled (which is the default) on a network which does not support it, all connections are noticeably slower in establishing. Disable IPv6 to get a great speed boost!

Windows: A few clicks of the mouse to *disable* ipv6...
Linux: A single command to *remove* ipv6 (rm /lib/modules/`uname -r`/net/ipv6/ipv6.ko)
