NetworkManager and Dual-stack Addressing

http://blogs.gnome.org – Dodge the pig! (via the|G|™ under CC BY-NC-ND 2.0) The big reason that NetworkManager 0.9 is slower to connect than NM 0.8 is that we flipped IPv6 addressing on by default.  That means that when you connect to a new network and that network supports IPv6 autoconfiguration via router advertisements you’ll get IPv6 connectivity.  But if that network doesn’t support IPv6 then you’ll spin for 60 seconds or so waiting for a router advertisement because there’s nothing on the network that listens to the IPv6 autoconf solicitations that the kernel puts out when the link co (General)

Stories similar to NetworkManager and Dual-stack Addressing

hi guys, I have a problem about ipv6 on F17. My network support ipv6. I add Code: NETWORKING_IPV6=yes to /etc/sysconfig/network. I use Network-Manager to access network.

After I connect the system to network, I can go to ipv6 sites and use transmission to download via ipv6.

I believe setting the IPv6 Address method to automatic makes it send a router solicitation, and it waits for the router to respond with an IPv6 address.   It is probably erroring out when it doesn't receive one.  If your router doesn't support IPv6, then either setting the ipv6 address method to either "Disabled", or "Link Local" is the appropriate thin

Hi All,

I upgraded to CM 10.0.0 stable this morning and in the course of things noticed that IPv6 wasn't working on my WiFi connection. I have native dual stack available and all my other devices have connectivity for both ipv4 & ipv6 (on WiFi or Ethernet)

After a bit of digging I noticed that the wlan0 interface was getting a global ipv6 address but no default route was being added.

RFC 2462 specifies:

5.5.2. Absence of Router Advertisements

If a link has no routers, a host MUST attempt to use stateful autoconfiguration to obtain addresses and other configuration information. An implementation MAY provide a way to disable the invocation of stateful autoconfiguration in this case, but the default SHOULD be enabled.

I wonder if I can communicate via IPv6. I know this depends on the ISP. Is there any simple way how to deterimne if my ISP provides IPv6 connection or at least if my router provides this functionality?

If there is not such possibility to use "real" IPv6, what is the best way to simulate it on Ubuntu?

How to promote IPv6? 38 weeks 2 days ago

I currently have the idea to deploy IPv6 on the corporate network of my enterprise. But my boss (CIO) asked me what are the benefits ? And I did not have an answer.

So what could I say to promote IPv6 on this case ?

It will run in dual stack with IPv4.

We use both Firewalls, VPN, and multiple WAN accesses.

I was looking for configuring Slackware to use ipv6 but all instruction I found speak about using an ipv6 tunnel that encapsulate ipv6 request into ipv4 packet and send them to an external router that extracts ipv6 request and sends a reply (or, at least, this is what I understood).

Is that necessary? Isn't there a way to configure a pure ipv6 system?

IPv6 Support for Linux 2 years 43 weeks ago

Hi folks, As we all know that most of the ISPs are switching from IPv4 to IPv6 due to several reasons. I have some idea about the IPv6 address format, addressing types and knowledge about Linux. So, I want to configure a system so that it can communicate using IPv6 protocol. Some of the services which I want to use on that system are ping( to itself), ssh(to it self).

AFAIK Ipv6 are unique over LAN and WAN

using this tutorial http://doc.pfsense.org/index.php/Using_IPv6_on_2.1_with_a_Tunnel_Broker

my lan network has now ipv4 connection and ipv6

I would like to be able to access my lan machines by their ipv6

i'm confused with firewall rules which i need to set to be able to do that

For now lets say that for the 3 interface (WAN / LAN / IPV6TUNNEL) i tell p
